Hi All BEC enthusiast,

I'm developing a reverse gearbox + overdrive (the RBox) for BEC owners world-wide. In the states, not only is there great demand for a reverse gearbox solution for BEC cars but also overdrive to reduce the rpms down whilst crusing on the street. This make the BEC a more viable solution for on-track/street use. It has come to my attention that many prospective builders choose CEC locosts over BEC because CEC cruise a lower rpms < 3,000 as well as better low-end torque. Of course, BEC can't provide greater low-end torque than CECs, but its possible to reduce those high-rpms down for crusing. We all love the sequential-shifting, high-reving bike engines but can't stand the high-rpms while crusing on the street or on short trips @ 70 mph. Below is quick look on youtube:

I've been looking for some kind of overdrive lately but everything seems wildly expensive or far too big. Your one looks like it could be just what I'm after. Any idea of cost and a rough completion date?

Looks like a winner - will the overdrive gears be helical as square cut could be very noisy?

Of course price will ultimately be the decider.

I'm looking at $1300-1400 USD and a ready date of early 2012'. I guess +- 650 euros for you guys? Box will use standard straight-cut (spur) gears to keep the cost down. I have a prototype (with reverse only) in my locoBusa and i don't hear 'whinning' gears as the car drives. Also, the design calls for a carbon-fiber cover and dual o-rings to prevent oil leakage.

I think you got your conversion a bit wrong there it's going to be more like 1000 euros or £900. Why a corbon fibre cover? Once fitted it probably won't be seen again. It's going to be quite an expensive unit so why not try and keep costs down.

seems a great idea. It was the reason I hardly used by bec when I had it. Always fancied taking it to work, but couldnt hack an hour of




RRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRR!

on the motorway

Is an overdrive ratio as big as that viable?

I've been working on something very similar for myself for a while. Straight cut gears, although helical is not a lot more pricewise, and dog change. Straight drive 1:1, and overdrive to bring bike revs down to little more than car. ~1:1.3+/-

Cost of the gears and shafts I've been quoted at less than £120, made here in London. The casing is £45 for a batch of 10, then theres the machining and the shift yokes. If a man was resourceful, he could make the whole thing using gears from one of the Hewland or the ex-Staffs racing 'boxes, for little more cost.

Should end up well under £400.

I'll be doing it when I get my little bike engined project moving early next year. I wouldn't be looking to make these boxes commercially, but if the demand is there...

Configuration will be with double input and output bearings, specifically for use parallel to the engine crank and chain drive.

I know I could get the gears made cheaper in USA, and where to go, but they want big batches(>100) so how matey is getting his pricing I do not know. £900 + freight, then VAT. Costs don't compute.

Cheers,
Nev.

Really looking foward to this. Do you have any photos?

Would be interested in how well this works out - the Z cars equivalent never made it past the prototype as it kept ripping itself apart.

After much thought, I concluded that overdrive ratio was far too high on the RBox. The consensus and research convey that overdrive should be a 30% increase of the nomal 1:1 or as already stated ~1:1.30 +/ or .80 , mine will come in at 1:1.22. Much thanks to Chris Gamlin's BEC speed/ratio calculator. I was able to plug my new OD ratios using the calculator tool and things are looking bright for the RBox. I can change the gear arrangements and make slight mods without having to make custom gears ($$). Also, I pondered on the pricing of the unit and concluded I can get the price down a couple hundress dollars ($1000 USD) ~ (727 Euros) or (£622).

As with anything developed in this world, you try it out and if fails you try some thing different - you live and learn. But back to the pricing, it's fair relative to all the others out there, especially if it's 1) safe 2) durable 3) does what its expected to do.

For educational purpose, why did your CF products fail? Have there been success stories using CF? Yes there has been. Some one please tells me about the success stories and not so much about the failures - we can learn from failures though, but at the end of the day we all want to know what made it successful. I do understand that the consumer will always push new products to the limits and beyond - that's expected.

I'm even more curious about CF as the gearcase now!!

---

Lets not forget that the cf part is just a cover to contain the oil. No significant structural support or housing bearing radial loads. I do expect some torsen or twisting forces. I have 5 long socket cap screw bolts that sandwich the cover and bearing plates together like the old eurotech fr2000 reverse box did. My prototype box in my car uses the same concept, except it has a 3mm steel cover.

I've got to be honest if this box works its worth the money

its £700 for a quaife box that has no over drive and leaks regularly (so im told). so at 900-100 it doesnt seem unreasonable

That's what I'm talking about mike! Quaife charges 900 pounds for reverse only.

I made this statement 10 odd years ago, (and was 'demonised' for saying negative things about Quaife!), when these boxes started appearing on the BEC scene, and IMHO nothing's changed! Still think that both are too much money by far!!

My version will be more costly, now priced at £1200, with choice of overdrives(£1500), so is much better! Still won't cost more than a third of that to make. But, if the mugs want to pay, I'll take the money. Next April/may when I get to it. Already got designs and prices, still got to make the patterns for the box and external shaft supports.

Cheers,
Nev.

Were I not a cynic Neville, I'd consider your riposte somewhat cynical.
Keep up the good work. No-one shall sleep so long as you police the technalia of this website.

I have a MK reverse - no disrespect to MK but its not the most elegant solution Ive ever seen, its using off the shelf parts and still costs £350 (I think a few people have sourced there own parts and knocked £100 of this price)

now to design and make a solution to do this and make a profit I dont believe for one minute anyone could do for £400 - the parts might cost £400, but labour, overheads, prototyping, testing, marketing, insurances (and all this needs to be done - as if it decides to come apart at 10,000rpm you probably dont want to be sat next to it!)

then you have the low volume - how many BEC owners are there? how many of those BEC owners are likely to purchase one?

I dont think you would sell more than a few hundred globally when your competing against quaife who come with a exceptional reputation in motorsport (be it true or not)

I see how quaifes costs £700 (partly paying for the brand I admit), and I see how a person trying to make a solution could end up nearer the £1000 mark.

To all the naysayers...

Look up gearcutting companies, ask them to give you a price to cut 10 sets(pairs) of straight spur gears with dog faces, say with a 75mm effective diameter, and an internal spline of 30mm od and six splines.

You should get a price of about £400, I did, but that may include a small discount for being a long term customer of sorts. And because there are 3 and a bit pairs in the gearbox, I get ten full sets for £1200.

These guys used to cut gears for top F1 Teams, and still do, and I've dealt with them since 1989. And no, I won't be telling anyone who they are, not publicly at least. The UK is awash with gearcutting companies, and they are very competitive at this point in time.

I can get the cases and external shaft supports done as rough castings in Southampton, for £800 for ten sets.

The gearcutters will cnc the cases and externals, and provide the shafts to what is designed. That leaves shift forks, which I have yet to decide on materials, but when I do, I would see them costing about the same as a pair of gears.

Bearings are standard shelf items, as are the seals. About £30 all up per box.

Add it all up, and you finish well short of £400.

Ideally, I would have liked to get gears from one of the race 'box makers, and also the shift forks to match, then it's a simple exercise to build the rest of the 'box. BUT, when they find out what you are doing, the prices skyrocket, and you may as well give them a blank cheque. Hence, the need to get everything custom made, and at normal industrial prices, NOT MOTORSPORT PRICES!

I said at the start of all this, that I see no market worldwide that would support a small business full time, so what I make will be for my own use, and the few who will benefit from the prices I get by ordering enough to build ten units. I'll probably hang on to two or three for my own use.

As for warranties, the bearings aren't a problem, been used in racing boxes for yonks, shift forks will not be any less strong than what's in your everyday drive, and may even end up being a shelf item from somewhere, and the gears will be to the same standard that a big name racing gearbox mfr gets.

But, none of this will happen until at least March 2012, as I've got a couple of paying projects to do in the interim, mostly so that I can make a reverse box for the bec I'm building, which will need a reverse to comply with rules.

If people don't want to buy because the price is too low, then their problem.

I see no reason to grossly overprice an item, other than greed, and people will pay what the market dictates. If I end up making 100/year, then that is still only a man in a shed for a week or two every month. Not a multi million £ operation by a long way.

You don't have to buy what I will make, nor even read what I've put. Your choice.

Cheers,
Nev.

I'll add this bit extra.

Everyone should be familiar with what a VW aircooled gearbox is. A large number will know what a Hewland Mk9 transaxle is.( A VW aircooled case with Hewland guts and rear casting.)

In the late 80's I had a discussion with a guy at Hewlands, and asked why their Mk9 at the time was over £2000, and a spanking new VW box was a bit over £300. The Hewland guy got up and walked away, never to be seen again. I was after a few boxes, and ended up with a USA made copy. Both the yank box and the UK box used a VW factory sourced gearcase, and both bought them by the 100 or more from VW in Mexico or Brazil, so churned out a lot of boxes.

You see, the VW box has helical gears, synchros, and all the extra work which that entails. The Mk9 is straight cut and dog engagement. Cheap and chearful to make as a gearcutter sees it, when compared to the VW. And the Mk9 gears are not made from any better material than the VW, as was attested to by a metallurgical report.

So, there is no reason on this earth why the Mk9 should be any more expensive than the VW, and many why they should have been cheaper. This is where greed comes in, and 'what the market will pay'.

You argue among yourselves, but if I can bring some sense to just a few people, I'll have achieved what I wanted, and everyone involved will be the happier for it. I'll have three, and I've got a few people contacted me, so the rest will move on fairly easily when the time comes, but these will cost a bit more than the first lot.

Wait until I turn my efforts to a 'box similar to the Caterham six speed, then the ship will hit the sand big time. Costs are as above, just add a few gears and shifters. A Ford Type 9, brand new in 1989, was a little under £300 from Power Products. A new rwd MT75 from Power Products is about the same as a recon anywhere else. And that is with Ford making a profit. Think about it.

Cheers,
Nev.

The subject of manufacturers making 'huge' profits often comes up on here and it surprises me that certain, apparently very clever people, fail to understand why companies have to make a reasonable margin on the goods they manufacture.

The man in the shed making bits as a hobby sees no other costs other than the bits he is bolting together. A company however has a heap of other bills to pay. Rent, rates, taxes, salaries, insurance, marketing, tools/equipment, electricity, telephone, bank charges... The list goes on and on.

The fact is that in small scale manufacturing a gross margin of less than 50% is likely to be insufficient to stay in business. That may seem excessive at first until you do all the sums. This is another reason why really professional companies tend to avoid markets with lots of men in sheds supplying. It is impossible to compete.

As for your man who is making the reverse/overdrive unit, good luck and don't let this obsession with price, drive you into compromising the quality of your product. A few pounds extra on a price will, of course, make people think twice. A reputation for noisy, leaky, unreliable units will mean they don't even consider buying in the first place.

Hi Mike,

I sort of understand why you would be saying this, though I do not agree with a lot of it.

I have already said that I would not 'knock' anyone's product, but I do not believe that the bloke in the States, and definitely not Nev, would let price compromise quality - or safety!

I would also point out your comment that "a reputation for noisy, leaky, unreliable units will mean they don't even consider buying in the first place" - does that not apply to the Quaiffe reverse box, yet so many people buy them?

Cheers, Nick

Mike,
Most of the techie stuff in this thread is lost on me. However, I do understand business basics and commercial realities.

My observations would be as follows: Whilst agreeing with the fundamental tenets of your post, I have two major misgivings, (a euphemism for 'I think you're wrong'. Firstly I don't think there's an 'obsession with price.' Certainly,not from Nev's perspective; rather, given his circumstances, his main concern would appear to be value for money. Secondly, that being so, it's axiomatic that the quality of his product would be paramount. Reading his posts, does he really strike you as the type to compromise quality by producing 'a noisy, leaky, unreliable unit?'

Just my two pen'orth.


Okay guys,

I think you have misunderstood my intentions a little. I was simply trying to get over the following points:

1 Why, when the bits cost £400, a selling price of £1000 is not unreasonable if you are running a company.

2 That given the negative response to his proposed pricing, the guy in the States may get the impression that he needs to drive down his price at all cost...

Adding to that.

Knowing Nev I know that he would not compromise on quality.

There is an obsession with price. Value for money is simply the ration between price and quality. Price seems to me to be the factor being discussed

And yes, people did buy the Quaife box. But why? It was the first commercially available product on the market and it has taken time for it's reputation to develop. I suspect that the sales of this product are not what they were. Given that Mike Quaife is an old friend of mine I find that a shame.

Whatever, anyone who is proposing to make a quality product at a reasonable price to fill a void in the BEC market needs to be encouraged in a positive manner and not confused by spurious arguments.

The only bit I can add to this, is that the costs of components I was quoted, went down by 40%~60% if I ordered in batches of 100. Basically, 2 for 1 if you buy a 100. Still a very large outlay for what I percieve as a very small world market. I have doubts that there would be sales of anywhere near 100 units/year, and to have the biggest part of £20k sitting in a corner is absolute madness, not to mention impossible while I have sons to support in long term studies.

As has been observed, I'm not in this for big profits, but I need to recover setup costs, which are relatively small as I am blessed with manual skills, so at the price threshhold I've put, for 10 units I'll end up even. The subsequent units would make me profit, and if demand rose, price would as well to the point where production and output were balanced until the market was saturated, at which point sales would drop off. This could be a year, two, maybe three, but I see nor more than that. Then Sales would be a trickle, and as I've put, probably very small yearly.

The setup costs for 100 cases are substantial, as the foundry wants to switch to metal moulds(dies) and gravity die casting methods, instead of sand casting in traditional ways. For 100 units, this is economical, and the dies are good for a lot more.

The machining setup costs are the same for 10 as 100, this goes for the gears, shafts,and cases. But, once the machine routines are on disc, the next 10 or 100 are already most of the way there.

Re Quaiffe and the others making reverse boxes, firstly, the first seller sets the price which the others follow. This first price is based on motorsport pricing, my opinions on same have been voiced far too may times already.

If a market is small, you either go into it at fair pricing and expect a long payback period, or not at all. If you have the first and unique product, you charge what you want until a cheaper and better version comes along. Then you drop your price, or your product.

Anyway, none of this is going to come together for 5~6 months. I could win the lottery in the interim, I might buy a good rain jacket first, and wear it constantly, to ward off the exhaust of the pigs passing overhead.

The business profit ethic in England was explained to me by a very wise and educated old gentleman many years ago, and it goes back to the days of sailing ships and trading in the empire. A man in The City would charter a ship, and send a full cargo of English manufactured goods outbound, on which he expected to double his money at offload. The ship then brought a return cargo, purchased with the doubled money, which was expected to bring at least twice the purchase price here in London. all of this in a twelve month. You do the sums. This ethic still drives the City traders, whom I despise, today. They mightn't get close to old time profits, but give it a good try. Shylock was a generous man, compared to todays cretins who run banks, pension funds, venture capital, and the like. I mix with these people in my sport of sailing, and I would not call any of them worthy of being friends. Maybe I should be living a simple life camping in the bush, living off the land. If life were that simple......

Cheers,
Nev.

Te That bit emphasised above is where you are all getting things out of context.

The bits are NOT costing £400, far from it as I've put earlier, and that's for a batch of 10. I make a profit at £400, to cover setup costs and labour. For 100 the costs near enough halve.

I'v been working on the carbon fiber cover for the RBOX + overdrive unit and was able get one half-way done. Thus far, I've layed up three layers and kevlar-hybrid and three of 2x2 twill 5.3oz black CF. I'll add another kevlar and CF layer as a "finish" to bring the thickness around 3mm. Then trim down the length, add oil fill/drain plug and mount engagment lever

I see that www.Beltingonline.com abroad in the UK has a nice selection of metric pre-cut gears!! I need many 17 teeth 2.5 MOD pinion gears to give me the right overdrive ratio (34/16 * 17/29 ~ 1:1.25) for the RBox.

You might find something similar to 2.5 module in the gearcase of a wiper motor, by way of example.

I'll try and be nice, so don't get upset unnecessarily.

Fella, you need to get some books on gear design, and study them, then try and understand what you are doing. 2.5module gears are meant for small industrial useage, and would end up as a bunch of filings in the bottom of any gearcase which is having bike power put through it. Remember, the engine torque is multiplied by the gearbox, before it gets to the OD/Rev box. This thing isn't a toy, and will have to handle a good deal of torque, and more than occasional shock load from having a heavy clutch dumped on it at a good amount of revs.

The cf, well, I won't comment further.

What you've made so far in ali is very pretty, but I think you may have to brush up on your engineering a little. Pretty isn't necessarily the correct design or strength.

I'm only trying to be helpful. I won't be making pretty, it's not seen. Function is paramount, and mine will be going in a racecar

---

I think that sums it up- the proof is indeed in the pudding. Lets stand and watch to see what happens.....

Ive been talking in pitches with the gearcutters, so have mixed terminology and numbers.

I can get the costs down by designing to use the cutters which are on hand. The guys at the gear makers have a very comprehensive range available, as well as what is currently in use by a couple of big gearbox mfrs.

I'll stand by what I've said on strengths.

Given the confines of a Locost tunnel, the geometry in which the box has to fit is fairly well fixed. A hyabusa at full chat in first gear will put a good load on the gear train, and this has to be accounted for, and not just reverse.

I've also got an eye to using the box for compensating diff ratios for cec's. It would be far easier, quicker and cheaper to change a pair of gears than to swap out a diff. This then makes it a viable option falling short of the big expense of cwp's, which give a fixed ratio change. Sort of like a quick change diff, but in the driveline.

I'm also looking at reducing part count, by utilising the old fashioned method of sliding the gears for engagement, thus taking away the need for dogs. Nice and simple, and keeping the gears in engagement by using helical toothform. Thus the driving gears will keep engaged with thrust. Only needs a very slight angle. Keep the reverse trio straight.

Anyway, at my current workload, this isn't going to happen until mid year, as I've put previously.

And 'yahshuatwo', I wouldn't have the effrontery to call myself what you have, knowing the origins of the words. Yahshua the second you most certainly are not. You'll have to explain it on the day.

Now, before throwing another hissy fit Mr.Yahshua, get hold of a gearbox out of a 2l~3l car, and check the gear sizes on the final pair of first gears on the layshaft. Then make them bigger by a percentage. It's as simple as that. You may find your 2.5 module a little light in comparison.

Cheers,
nev.

Nev
I'm glad you know a little about 'Yahshua' because 99% of the world does not!. My intent is to give YAHSHUA credit and glory because he helped me design the RBox anyhow. I've decerned your 'intent ' all the way since your first post on my thread and It has been
nefarious, planting doubt, attempting to discredit my design without proof. Get the behind me Satan thou art an offense to me.

All you're doing is making me more determined to prove you wrong!

Go research 'Dr. Kinley' you might learn you some sense.

I'm man enough to admitt my design flaw if the current design doesn't pan out.

I would, in all sincerity, want to see what you build succeed. Whether buyers will prefer a pretty, expensive item, or a cheap functional item will be borne out with time.

You come across as a very cocky and mouthy youngster.

I'll leave you to your own now, after all, you seem much more informed than I, as you don't have the need for reference books.

The art of a good engineer, I was taught, is not to carry all of his knowledge in his head, but to know where to look and find the knowledge, and how to apply it. You may have John Boy and Billy Bob in their NASCARS to talk to, I'll stick to my teaching of First Principles, and where to get my information in particular references. Then there's the gearcutters who have, and still do, make gears for top racing classes, whose ear and interest I have had for far too many years.

You, by your own words, are above this. You know what you are doing.

Please, get your gearbox built and sold to a punter here, then I can see how, or not maybe, I should proceed.

Cheers,
nev.

Nev, not mad at you but a little annoyed. Sounds like you know a thing or two about gears and transmissions. My design is so simple, no need to re-invent the wheel. But when it comes to YAHSHUA you don't know who you're dealing with. I would happy to give you some reference material if you desire. I'm Yahweh and so is everyone else.

Sorry if I have offended anyone on this thread

Yahshuatwo.

I won't even begin to answer that lot.

Get on with it.

Cheers,
Nev.

The world is full of cranks and crackpots. Some places moreso than others.

I think I'll go find an abo, a roo thighbone, and.....job done!

Yamaha, Suzuki, Honda and named others, have already proven my design at some degree. I'm riding there coattails if you get the point.

I'm not a cocky youngters, you drove me to that disposition with your comments.

Your Target market is definitely not BEC locost! No one can afford your design from what you're describing. My product will be competitive with Quafie and Westfields inline boxes. I'm not targeting 400 HP/175 ft torque applications at the moment. Most installations in the states don't even have busa engines (ie. 190 HP / 110 ft torque) but my design is resilient. Potential customers can 'upgrade' bearings, shafts if needed
In all fairness, we i different target markets - there is plenty of pie to go around


Nev, Do your research on Dr. Kinley.

Cheers,

Ryan

Look up Dave Gorman, he had an interesting interview with that mob of nutcases you are referring to, shown here on TV a few nights ago.

Ok will do. Was Christ a nutcase? How can you prove he existed? some might call you a nutcase for designing a box no one can afford
This creation is a great mystery. Graham Hancock knows some stuff too. For what ever you seek, please demand proof.

Jesus, you guys need to give it a break, or change gear

We are Steve M, its just our egos and competitve nature playing in. I'm designing a gearbox, Nev is designing one too. Nev attacked my design first out of his insecurites, so I attacked back. No hard feelings between us two; Nev seems to be a very knowledge bloke with a lot of experience. No need for us to spat anymore, there is enough customers for both of us, although his product isn't 'locost' affordable. I'm gonna be the bigger man and change gears.. I will at some point ask Nev for friendly advice if I run into a snag with my design.

My design uses spurs gears like most of the jap 1 litre bike engines. They may have a little more backlash than Nev helicals, but the'yre stronger and not as loud as most would expect. I built a prototype box in 2010' and have it install in my 02' locost yahbusa car, and it works very well. I haven't driven it in a pure racing scenario, but i'm confident it would hold up well.

God Bless Nev, and this forum. I've learned a lot about BEC building from everyone's input through the years on this site.

As a very, very final word from myself, I will repeat my initial post, abridged for today, and only add that this IS a personal project, and not for income, so no, I don't have to price to make big profits. I'll stand by all I've put below, and as I work 'in the trade', I can assure everyone that what I've put is as things are today. Steel and aluminium prices are rising, and the little that the price may rise is not a significant factor at present.

I am not in this to compete(except on track), and most here should by now be well aware of my gross disdain for the pricing( and excess profiteering) of motorsport and performance targetted parts.

I will be here for the foreseeable future, to give any support necessary, by way of parts and advice.



Finally, I'd like to thank all of those who have contacted me. I am keeping a short list which now near justifies a short run, and will be in touch when I get this project underway in earnest.

Cheers,
Nev.

Cost of the gears and shafts I've been quoted at less than £120, made here in London. The casing is £45 for a batch of 10, then theres the machining and the shift yokes. If a man was resourceful, he could make the whole thing using gears from one of the Hewland or the ex-Staffs racing 'boxes, for little more cost.

Should end up well under £400.

I'll be doing it when I get my little bike engined project moving...... next year. I wouldn't be looking to make these boxes commercially, but if the demand is there...

Configuration will be with double input and output bearings, specifically for use parallel to the engine crank and chain drive.

I know I could get the gears made cheaper in USA, and where to go, but they want big batches(>100) .............................................................................................................

NEV, one final note also for you... Please don't highjack my thread, start your own where you can solicate your design - very unstatesman to do mine. I will be happy to provide you a per diem for your knowledege (westward) IF required.

thanks again Nev for making the thread lively, I wish you the best of luck on your project.

another take at the RODBox with shift mount attached. I need to drill another hole thru the CF for the ball plunger set screw (will keep gears in correct position without sliding around). Man, the CF cover is resilent!! Strong, lightweight, definitely will take a beating.

Received the 2.5 MOD gears from beltingonline and moved them to the local machinist for boring and spline broaching- expensive - we will see? Those gears will work swell after hardening and stress-relieving.





[Edited on 25/1/12 by yahshuatwo]

Just a few weeks out from testing the FNR + overdrive RBOX. I can't wait to see it in action. I sold my prototype reverse unit after making a few mods to it. The gentleman who purchased it will install it into the following:

http://forums.24hoursoflemons.com/viewtopic.php?id=11901

this is an endurance race in the states, so my prototype will be put to the test..

Any news on either Nev's or Yahshuatwo's reverse/overdrive boxes yet?

Yahshuatwo's youtube link no longer works and he doesn't appear to have been active on here since his last post in March...........

Im still here and working out some kinks in the design. I ran into some oil seal issues with the CF cover (im sure Nev is happy to hear this). easy fix and will male it happen soon. I have two boxes completed and to ready begin inital testing , minus oil seal issue.

hi, sorry but i havent time to read the full topic, ive had my westfield reverse gearbox in my car for the last 8 years with no problems & what ive always wanted is to be able to change the gear ratios with out keep swapping the diffs over, at the moment i have a blade 893cc feeding a quaife 3.21 LSD diff via a 1:1 RGB.

So one day i would like to do a sprint/ hillclimb, the next doing to a trackday say around silverstone & the next cruising along a motorway to a kit car show, so in in a nutshell & preferably in layman terms what has yours to offer?

I'm also still interested in a sensibly prices reverse box with over drive.

Update:

*Overdrive gears have been shipped to be heat-treated (induction hardened); I'm waiting the status / shipping date.


* Any BEC owners in the North/South Carolina? I'm looking for a tester immediately. I have a special incentive for the tester.

Over the past several days I've been thinking about the reverse unit and pricing once again. I developed a business model that supports a reasonable initial price-point and offer services that hopefully will make potential buyers happy in the long-term. So I will overview the
R-Falcon features and business model:

R-Falcon Features:

*1:1 Forward, 1:1.25 overdrive and reverse (dog-meshing for forward, overdrive is just gear-to-gear - doesn't support dynamic shifting on the fly)

*Aluminum bearing housings /w carbon-fiber/Kevlar cover

*Epoxy sealed unit - this guarantees no leaks after some unsuccessful attempts to use O-ring seal on the CF/Kevlar cover to the aluminum housings. Purchaser/owner will not be able to disassemble the unit due to the epoxy sealing which is further explained in my business model below.

* Supports up to 250hp/120 ft torque when using the Robinson Industries Heavy-Duty output shafts (28mm x 13 spline vs the oem 25mm x 13 spline) - I contacted Bill Robinson about becoming an authorized reseller of the heavy-duty output shaft and we're going to partner-up. The only issue is finding the prop adapter to match the bigger spline profile. They make the counter-sprocket for the bikes but I need to source the prop adapter - I may have a source in mind.

I recommend purchasing a resilient torque shaft for the front (engine to unit) to mitigate the BEC "clank" experience. I've driven my car with a FR2000 Eurotech box, my prototype and the R-Falcon; I still seem to have that experience occasionally regardless of the reversing unit.

Business Model:
1. Buyers can purchase a new reverse unit for $1100.00 (£717.64). The units include everything necessary to integrate with the BEC car except for two prop flange adapters (separate purchase).

2. (Optionally) buyer may purchase a gearbox "rebuild kit" services $250.00 (£163.10) + shipping. This will allow the buyer to have the unit service rebuilt by us due to bearing wear or other issues. It kind of gives you a warranty/insurance. $250.00 will include:

Inspection of the unit
New bearings pressed in
New CF/Kevlar cover
New oil drain/fill bungs
New shift mount boss oil seal
Original shift mount boss will be retained
Original fill/drain bolts retained
Original shift lever retained

Box is resealed, tested and shipped back to customer. Customer needs to retain original shipping box/crate.

I think this model is fair and is competitive in pricing with the "other" units out there. Again, the rebuild service is optional and can be purchased anytime, and it does allow one to extent the service life of the unit, protecting the initial $1100.00 investment. The "guarantee no leak" is the main directive behind the new business model

Finally, we will not offer refund/warranties on the unit (as other don’t offer due the nature the use) but we'll offer "No DOA (dead of arrive) time period" clause/terms of use.

Thanks,

Ryan

Davegtst - 26/6/13 at 04:01 PM

Am I reading right that you can't change into overdrive while you are moving?

---

yahshuatwo - 26/6/13 at 04:57 PM

Correct. I've done some prelimenary testing in attempt and its a hit or miss. Overdrive engagement isnt dog-mesh similar to bike shifting. Overdrive down to forward 1:1 is possible but from forward to overdrive will lock 95% of the time, especially at high rpms

Overdrive is intended to road crusing, foward 1:1 is normal as all the other reverse unit do.

Maybe I'll redesign the unit down the road to accommodate this feature.

I'm gonna try to post a youTube video tonight/tomorrow going through shifting of the box -- stay tuned..

Hats off to Chris Gamblin's Bike ratio /speed calculation tool! I modified it to include the R-Falcon reverse unit..
BEC ratios speed using reverse units

Not at this pricing point. The main driver behind the current design is to simply offer an overdrive gear in which Quaife, MNR nor Nova offer at the present time. The dynamic shifting required for overdrive will be considered, but just not in this release.

Again, my main objectives derived four years ago where as follows:

1) Develop a reversing solution which could potential be sold under $1000.00 USD . We're can possibly get under that pricing point once we tweek the manufacturing process and re-coupe the initial R&D costs

2) Offer a badly needed overdrive gear to: a) reduce crusing rpms/noise (better fuel effieciency ) , b) faster top-end



In the states it's hard to find a donor vehicle with a rear differential ratio < 3.62. 4.11 in a BEC at 1:1 in the reverse unit will be quicker
off the line but max out top-end around 110mph. 1990's Subaru Imprezas, Legacies and SVX offered these ratios in the US:
Impreza/WRX 3.89 expensive for the 3.89 from a WRX, 4.11
Legacy: 3.89 visious LSD (Turbo) Hard to find, 4.11
SVX 3.54 ( hard to find)
Others vehicles: mainly live axles with > 4.x ratio



I luckily found a 1992 Legacy Turbo with a 3.89 visious LSD back in 2003.

Price and feature compare the R-Falcon against the competitors and you'll see that we have a solid deal. Our product just hasnt been proven as of yet.

Cheers,

Ryan

sdh2903 - 26/6/13 at 09:48 PM

Surely there are plenty of e36/46 bmws in the states with lower diff ratio's than you quote? Mines a 3.45 from a 318is, the 328i iirc was a 2.97 diff, early e36 m3 was 3.15 etc and thats before you look at the different larger series cars.

Good job perservering with the project although I too would only be interested in a selectable when moving overdrive to be worth the effort replacing my current mnr box.

ceebmoj,

I just uploaded some picks of the R-Falcon on the front page

---

Davegtst - 28/6/13 at 09:34 AM

OK, so it's £718 plus shipping plus import duty. That buys me an untested unit that comes with no warranty from a relatively unknown manufacturer and it can't be changed while driving. To be honest mate I don't think you will be getting too many buyers this side of the pond.
To be fair to you it does look like a quality item but being a brand new untested design I would want to know exactly how it was built before I spent that kind of money. Just a couple of observations: how do you mount it to stop the whole thing spinning? Why oh why did you make the shell in carbon fibre? Aluminium or steel surely would have been cheaper and easier to make and you are never going to see it.

matt_claydon - 28/6/13 at 12:49 PM

I agree with the comments on the business model; I don't see anybody buying an unproven product from thousands of miles away with no warranty.

Don't see a problem about the lack of dynamic overdrive shifting though - you have six gears available at any given time from the bike 'box, why would you want any more? This is more like an easily changeable final drive ratio, tall for road, short for track.

---

yahshuatwo - 28/6/13 at 01:45 PM

Well, perhaps I should consider a tester in the UK? I will be willing to do that if someone wishes. Its a far way over the pond and some type of contract would have to written up to ensure my product is returned to the states after testing. I'm currently seeking a tester in the states in my area right now. I have a potential tester on the west-coast with a Mini/VFR setup.

I had no intentions of selling my product without testing; right now i'm just promoting the product.

As far warranties, well, i'll probably will need to do some research on the competitors. I know for sure they're products have been proven but i'm uncertain that they offer any warranties as well?? And yes, unknown + unproven + no warranties = no sale across the pond


For me as a start-up in a niche market where few sales are expected, I chose the carbon-fiber/Kevlar cover because its cheaper and more convenient to manufacture (in my shop). I researched and tried the alum or mild steel route and most shops wont take on small orders, plus they cant seem to get the CNC radii bends right on the corners. And Westfield, Nova and Quaife with the two piece T6061 alum housing still appears to have oil leaking issues, whether it be the around the shaft bearings or the casing split?? I purchased a EuroTech FR2000 back in 2004 off ebay to put in my car. It worked ok and occasionally would lock-up; it spewed oil out the shaft bearings and leaked around the bearing housings/cover mating (no metal or rubber gaskets). I took queues from this unit to design the R-falcon.


I will concentrate this weekend on making a youtube video on the break-down of the R-falcon. We'll look into the internals and seen how it works. Back to the proven: I know the internals are proven (gears and shafts) because they're Suzuki OEM parts.

I think the manual overdrive is a better selling point in the states. Builders over here have asked for it. They're probably not familar with the low diff ratios found in the BMWs.

I think its quite a good idea

a bit like on a jeep/landrover, you have a high ratio for the road and alow ratio for off road
like matt_claydon said on this you'll have your crusing/high gear for the road or really fast tracks
and your sporty gear for the tight twisty bits
same way that racers change ratios for different tracks but without the hassle of changing the diff/gearbox

the BMW diff's do have some decent ratio's, but from what I've seen they are quite big and heavy and don't have a reverse

Received the newly heat treated overdrive gears yesterday. They have Rockwell hardness around 55-57 HRC.
this will get the job done! Gear on the left is C45 steel; I had a shop cut the internal spline profile out using EMD, then it was heat treated.
on the right is a make shift gear (bored and weld in spline) used for development.

How long have you run the box in you're car for? How do you engage reverse or over drive?

Final design been in the car for two years , built prototype three years ago. been up and down street in the car, but limited use cause car still unfinshed after ten years

reverse is a no.brainer,.overdrive works great but need more thorough testing..

I'll test it for you. What are the terms?

We finally come to a point where serious testing can take place with R-Falcon reverse box. Carbon fiber/Kevlar cover is holding up very will. I mounted the unit in the chassis over the weekend and took a short cruise around the community. The next step will be to dyno it at high rpms and see how stable it is. Then off to the track. And Yes, I will install steel mesh around the shaft tunnel just in case....

Unit isn't leaking oil; will do further testing on the reverse and overdrive gears
