Has anybody raced in this? Thoughts / opinions?

Many Thanks

I blogged about it a while back.


livelee - 19/8/10 at 11:17 AM

Cheers, nice blog entry.

I've looked at the lap times and the cars competing. I'll be in Class C with my fairly standard 2.0L Zetec. Seems you need a Caterham and a large budget. Do people with MK, Mac etc not race or are their other series where they race? Imagine Hispania in this years F1. That will be me. lol.

Thanks

Dan

And yes I am in a similar (but CEC) situation to you. My car wont fit into the 750mc kits series due to running TB on the engine.


TimC - 19/8/10 at 11:57 AM

To be honest, I'm only aware of four MKs racing - three in the North West Championship and one in 750MC kits. I've never seen a Mac#1 racing.

The slowest cars are very slow in the turns from what I could see and the fastest cars are ballistic. I'm sure you'll find people to race with.

I should say that since that blog entry its become clear to me that my car certainly would be eligible for RGB which is really good news. Mag7s does seem to be very good VFM though, and I'd be tempted to try to form a two car team as concentrating that hard for 50 minutes takes some building up to I suspect!

Hi

Yep we have run three of our LA Golds in the sevens. That's with 750 kit spec 1800 zetecs with 170 HP. It's fair to say that unless you spend something like 50-60k on a motor you are not going to win out right.
However we have had some promising results with a 3rd in class and 5th overall.

With something like a good reliable 200HP similar results should be achievable with a good driver OR two if double driving. To finish higher your looking at 260 + Hp and a 6 speed sequential G.box as per the high spec R500's.
There is more and more Kit racers slowly moving over to the Sevens championship due to the 750 Kit car championship being left with no sensible regulations or scrutineering to stop the cheating. More than a few have sold Phoenixes and switched to Westfields or converted phoenixes in to Strikers to compete. But most are aiming for the 200+Hp class.

There's also the north west sports cars championship or what ever it's called ( sponsors name on championship ) This is where tin tops and specials run side by side and again there is no real regulations and they are using slicks. This would give a better chance of an overall win for the more basic kitcars as the lap times are relatively slow considering the regulations being more open Ie they are only on the same times as the RGB times on 048 yoko's. Most of there rounds are based more around oulton and croft occasionally Mallory and Cadwell. Where as the Sevens is more mid to south based with outings to Spa. There's also the SEMSEC championship where highly modded kit can run but there champ rounds are based purely at Lyden and Brands hatch and with entry fees of £310 per race at lyden for very few laps it really just doesn't add up to being sensible compared to other's entry fees in comparison for £ per laps remembering the seven are 40 min races with one or two drivers. with compulsory pit stop for driver change or 1 min stop. remembering there is no refueling allowed during the race so a large tank needs to be taken in to consideration.

Any Q's i can pass on some details for the guy who is running the Sevens championship.

Cheers Matt

Oh yea forgot about the Welsh championship. Sure Tim knows more about that than me. Only ever setup one or two cars for that championship and don't really have any knowledge of classes or regs. seem to remember thinking you would need to lap at around 1 min at Pembrey any quicker and they ballast you up or something similar. But a good Kit with 170Hp will lap Pembrey at around 1 Min as a guideline.

Cheers Matt


Andy D - 19/8/10 at 04:12 PM

..and, dont forget the NSSCC. Northern Saloon & Sports car championship. It's as it says.. a mix of cars, with classes for slicks and 1bs. My son is currently racing his Honda Civic in the 1600cc class (D) There are a few kits racing too. Caterhams, Westfields, the odd F27, Fury, and Ginnettas etc..

We race mainly at Croft, but there are away races at Cadwell, Mallory, Knockhill and in the past, Oulton and Anglesey.





livelee - 20/8/10 at 12:14 PM

Good info there Matt, many thanks.

Being based on the IOW I think any Northern championships would be out. The results you've managed with the 1.8 Zetec is encouraging, I'd imagine my 2.0 to be around 170bhp.

The cost of upgrading my car to get closer to the front would pay for a Locost so that might be another option I should look at. Keeping my existing car for trackdays and faster laps.

For interest what do your cars lap Brands Indy @?

Cheers

Dan

In case Matt misses it, Steve Lansley in his LA Gold is in the low 54s.


livelee - 20/8/10 at 12:26 PM

Cheers. It's a target to aim at.

Regarding the other kits racing, I guess it's either the people buying them are not racers or the chassis are not good enough to be competitive.

[Edited on 20/8/10 by livelee]


progers - 20/8/10 at 01:04 PM

Just for clarity, the 54s time is for a 750MC kitcar series spec car. The locost lap record is 58.5 secs.

Ah, go on Mr Modesty, you might as well mention your own 50.46 record while you're posting.


progers - 20/8/10 at 01:24 PM

Nah far too modest me

I was going to mention that fireblade engined seven is capable of doing high 52's though, not bad for a farty 900cc engine

procomp - 20/8/10 at 03:37 PM

Hi

52's ain't bad. But allow the kits to shed the extra 35 KG of regulation min weight and fit an ATB. They would be knocking on the door of 51's.

Cheers Matt


livelee - 20/8/10 at 03:42 PM

What do your Golds weigh Matt? so with an LSD you think they would make the 51s?


procomp - 20/8/10 at 03:56 PM

Hi

As a CEC they can be built as low as 480KG engine dependent. kits require a 535KG minimum weight +success ballast for the zetec class.
The ATB or plate diff depending on exact application of use will make a big difference to corner exit / following straight speed.

Cheers Matt


livelee - 20/8/10 at 04:03 PM

Interesting, so you're circa 315/320bhp / tonne in kit spec and that's good enough to deliver a 54 @ brands.


procomp - 20/8/10 at 04:12 PM

Hi

Yep but if you take a look at Kit results i am pretty sure you'll find that a 54 is a time taken from a race situation with traffic. Where as Paul is quoting RGB lap records. So kits with the zetec are capable of achieving 53.3 in Kit regulation spec.

Cheers Matt


livelee - 20/8/10 at 04:20 PM

Cheers, yes I am interested in times relevant to cars similar to what mine will eventually be. BEC does not interest me.

So I now need a low 53. Jolly good.


TimC - 20/8/10 at 04:24 PM

What about a 210 BHP red top Gold with Alcon brakes - what would you expect that to lap in?


livelee - 20/8/10 at 04:32 PM

Well that should be circa 400/tonne. Based on what we have been talking about here and the laptimes in the Mag7 i'd expect a high 50 or a low 51.

Matt has the front end geo on your Golds changed much since that one was built (2002)


procomp - 20/8/10 at 04:42 PM

Hi

Ehhh what we talking about. Is this a specific car !!!

Cheers Matt

procomp - 20/8/10 at 04:58 PM

Hi

Oh yes there's been just a few updates since then. The whole chassis rear suspension front suspension. That is one of the very early ones sold 2000.
Good engine but brakes are just a little overkill. That particular car would not be on the pace with one of today's versions. Still a very good starting point as it would save waiting for me to find time to build one. Modding that to later spec would be quicker.

Cheers Matt


livelee - 20/8/10 at 05:02 PM

I'll revise my lap time prediction then and say maybe 54/55.

The front end did look a little "dated"


procomp - 20/8/10 at 05:17 PM

Hi

In all truthfulness even a 54-55 round Brands will take some building up to. The dive down into paddock hill needs a good setup that wont bite. And getting traction out of Druids and Grahame hill will require some playing with dampers to get best results from traction. Those are possibly lap times to build up to through the day rather than say 10am.

Cheers Matt


livelee - 20/8/10 at 05:20 PM

Yes they are a target to aim for,not an expected result at 10am.

Brands will probably be my 1st trackday / testday in the car so with something to aim at and if I can come away close then I know we're heading in the right direction.

Lap record is actually 52.5, in a racing situation they are typically just dipping into the 52's i.e half a second slower.

I have no doubt a well built CEC with 180- 200bhp would go faster, I was just being cheeky and pointing out the advantage of low weight in a track car :-)

- Paul

P.s. How are your feet recovering? Get well soon (and no practicing heel and toe technique )


livelee - 20/8/10 at 06:53 PM

So assuming p2w is equal what's the general rule for BEC vs. CEC in race conditions?

BEC wins on tight courses and CEC wins on the longer more open ones?


steveiow - 21/8/10 at 02:33 PM

Dan - would be good to see you racing in 750mc events if the car fits into the right series. That would make 3 of us from the little Island as I believe Baz picked up his stock hatch today.


Procomp21 - 23/8/10 at 11:16 PM

For best results do as follows:
As you travel down the start line straight clip the marshall's post on the right. Hug the pit lane to the right (it is downhill) until you pass you are 3/4 of the way down. Move to the left and when you think you are at the end of the straight keep it nailed, because you have another 400 metres to go. Aim for the pit exit line to the left and brake like XXXX. Once you see the apex nail it. Enjoy the feeling of going to the moon, and use all of the kerb available on the left (you will need it). Travel up the hill at full throttle and dont touch the brakes until you arrive at the bridge before Druids. Take a 3/4 line to the left and get the power on as fast as your car will let you down to Graham Hill Bend and get over to the right then take loads of kerb on the way in as early as you can, but dont hook your wheels over it as it will slow you down. As you approach the chicane at the end of the straight give a momentary lift and the go through flat out (this requires some balls). Once through straighten the car up and barke hard. Turn right and aim for the right of the new MSV building and use all the left hard side of the track, then aim for the Marshall's post onto the start finish line. Repeat for 20 minutes whilst defending your race line. If you get it right you will lap in low 54's. Good luck (but what would I know)...

How do you get 170bhp from a 1.8 zetec? Im already thinking that its going to cost a small fortune

So when is someone going to suggest a rule change? My suggestion I keep banging on with is to run with engine intake restrictors, and no rules on engines and spec, with exception of no knock sensing and no forced intake.(This leaves out the F3 engines, which hand grenade even with knock sensing)

Classes then based on restrictor size and weight.

Cheers,
Nev.
