Busa engined middy build

Gakes - 12/10/09 at 04:59 PM

Hi Guys,

Heres a few pics of my bike engined build based on my first car (learnt a lot from all the constructive criticism. Im using a Sierra diff(3.36), made up some Haynes style uprights, VW starter for reverse, custom revers gear, cortina front uprights and Golf 3 steering.

In the process:
machining reverse gear and fitment of Discovery 1 rubber coupling as cush drive

Next on the list:
1.Fabricate starter mounting and fit electric starter

I am in awe of all you people with the talent to build things like that! I lake the imagination too!

Very nice so far, keep us posted!

Superb!
Some classy fishmouths there, do them by hand or some special tool?
Can't wait to see more

Gakes - 12/10/09 at 05:33 PM

Thanks for the nice comments.
I've learnt quite a bit messing around with my first car and not taking any shortcuts this time

Just a grinder and lots of time

Nice

Looks very atom/moterleira-esque

Miks15 - 12/10/09 at 06:45 PM

looks very tidy! look forward to seeing finished product!

One question, how come you decided to mount the busa longditudinal and not transverse?

prawnabie - 12/10/09 at 06:51 PM

Im shocked no-one has mentioned the lass yet lol

OX - 12/10/09 at 07:17 PM

very nice but like prawnabie has said why are you putting it in the wrong way ,,with all that room it should fit in a doddle

Gakes - 12/10/09 at 07:25 PM

Im mounting the the engine longitudinally so as to use a prop instead of a chain drive. Not too keen on a chain snapping

The diff is mounted offset to the right with the engine just left of the centre. This will also keep most of the weight as low as possible and compact as possible which in turn will hopefully balance her a bit more.....in theory that is

I hate copies!
Nice job, welcome to the dark side

Luke, I am your father..............Nooooooooo

Boy howdy she looks bored but at least she's in the shed, I used to have one that would sit in the shed and give me that look too. It did not end well.

For the tube notching I'm guessing he's using somerthing like this:

Which fits in a pillar drill and uses hole saws to cut the tube. I have a similar device and love it as it makes you look like a tube fitting genius.

lol. Honestly I just use a tape measure, marker pen and grinder.

I did however build a mini milling station this week and still looking for long hole saws here in South Africa. But that little machine Doug38 posted was looking pretty tempting

Then you need to stop wasting time and get the "Tube Mitre" software thats floating around the net in many places, brilliant little program I even emailed the creator and told him so with a big thanks!

Your girl looks like she needs some build time too.

Gakes - 4/12/09 at 05:42 AM

I've checked out the software. Didnt use it cos I didnt know how good it was. but if you say its that good, I will give it a try. I've just invested in a set of good Bi-metal hole saws. We'll see how they work in a drill press.

Heres more pics of the build. I sold it to a guy in California, Cord. He is busy with a Sonic 7 as well, and I can see he has a good eye for these things.

Like we did:

undies-03

...about 7 years ago.

(Ignore the 'cake tin' exhaust - it was an extreme effort to meet Bedford Autodrome's noise restrictions - and it worked!!)

I wouldn't be worried about chains snapping, I competed in the RGB championship for a few years in a BDN and never experienced a problem with chains. Out of the cars competing in the RGB there were far more problems with props than with chains. Using chains gives you a lighter solution and it's certainly much easier to change ratios.

Below are a couple of shots of the rear of the BDN S3, which has chain drive:

also using a prop makes the car longer

Gakes - 5/12/09 at 06:29 PM

Thats the idea "tadltd", nice job What engine you using?

Bobbus, thats a good setup as well. The guy that ordered the car(Cord) wanted a rugged setup to take lots of power. I have also seen some chains snap on the track, maybe they weren't serviced as well as yours. Dont get me wrong, the chain drive was tempting as well.

Heres a diagram that illustrates my idea:

cheapracer - 6/12/09 at 10:52 AM

When I look at tadltd's picture and your chassis it looks like it may be a tight squeeze? (bum to axle distance).

Yeah that software is great, I always told the software that the male tube I was using was 1 mm bigger than the female to allow for the thickness of the paper and 2mm wall thickness.

Not necessarily. I measured an actual Quaife & 'Busa chain setup with reverse, and then measured out a longitudinal 'Busa with differential. There's less than 1" difference in length. Either way, it's a tidy little package in the xO400 with lots of extra room.

I actually requested this design from Gakes, less for chain snap and more because I thought it could be reproduced at a lower price than the Quaife solution. Not that it's better, just as a proof of concept. Gakes filled in the details quite nicely, I think.

aitch - 10/12/09 at 04:59 PM

my idea for busa engined midi

only in a draw programme not in cad so its a bit basic.

locost front suspension and uprights from Rally designs and haynes rear suspension and upright from 3gecomponents so a major cost but worth it i think for tried and tested parts

sierra drive shafts and diff converted for chain drive, escort steering rack

nothing at all way out there or new really, this will be fully enclosed GRP composite bodywork

aitch

p.s. hopefully pic is small enough to see now and ill start a new thread soon with thought process

Great layout Aitch, just flip your front wishbones around I think it will help the Kpi.

I hope you get starting soon

thanks gakes i could have been going off road and this pic been posted in three places although i realised you are the only person that pointed it out
