DTRC Snetterton

[graham bahr]

forgetting the US stuff for the moment ( i know nothing about it) yes a locked diff does initially do understeer and as Al says switches to oversteer once enough power has been applied, i've tried it in light lowish powered cars and it works, but with a heavy car and 500+bhp its going to be enormously difficult to get a setup that will allow a smooth slight tailout attitude, the things going to be on a hair trigger as to whether its going off backwards or forwards.

What happened to Kris Waits Cosworth, how bad is the damage ?

That cars spoiler brings new meaning to 'Whaletail'.

[chezza]

Oh blimey looks like I missed lots of drama!!

Update on race 1 classification - with the race only being scheduled for 10 minutes that meant that after 5 minutes a result would be declared should a stop happen. With the stop after Kris's incident the results were given at 4 laps.

After Alan's query we went back to the timekeepers who checked back through their times, the result being Alan was now shown as a finisher but Alex and David, having only completed 3 laps when the class winner had completed 4 laps, still fell foul of the 80% rule.

Ultimately it was the very short race distance that caused the Not Classified problem.

Aside from that, a tremendous variety of cars and THAT rear wing certainly was a talking point!

If I ever get this Penske IROC finished Graham I will book into a track day and you can have a go and see what you think, I am not 100% sure whether it has the locked spool or a detroit locker (slipper) I will try check tonight. I agree with what you are saying and although this is the way they seem to go in the US I don't have the bottle to try a fully locked spool.

It's RWD Al, but running a locked spool is not a good idea at Snetterton, or anywhere other than a shale oval in my opinion!

Rob.

This was Kenny Coleman of EDA as it happens and he ran a Big Block Iif I remember correctly, talking to Johns engineer (unless he was spining me a line) they are using the Windsor engine which is by no means the best in the line up, almost like the 305 Chevy, i.e. longer stroke to bore ratio, there are much better lumps in the Ford line up, a Cleveland for one but I do believe from what I was told that is being worked on.

Thanks for all the pics...sounds like an eventful weekend!

And if Andy Pipe is reading, your left rear wheel was bouncing badly under braking for the right hander at the Esses - what was the cause ?

Dunno, just think slamming it down to 1st for the right hander dont help

[Al Weyman]

Try some double adjustable rear shocks Andy.

Memo to self..................Ring Gaz

There's a name I haven't heard for a long time. Gaz the shocker man....

Or Try taking it in 2nd? or is that too tall?

I seem to remember using 2nd around there in my 1600 Nova (the thing that's sitting outside here rusting....)

Due to the rules (earlier classes and championships) we have very short dampers on Andy's car, and as such there is not a lot of droop, so under braking the car has a tendency to lift, And as Andy is racing against the FWD' ers who all lift a wheel through the corners we thought we would copy them

We may turret the car next winter which will allow the use of 13" closed length 3 way adj' dampers as I belive its now legal for Andy to have turrets and not have to use the original suspension pick-ups.

We had also had backed of the damping on that wheel from race one ... but even with the bouncing he was 2 seconds quicker I belive..

[Al Weyman]

Those guys in the Pre 74 Post Historics really get those Mk1's flying, have a deco at what they are doing, we are out in force at Brands on the 28th May.

[retro_msport]

Al, Les Lyons in his class B RS1800 holds the Silverstone lap record for Class C, 1m 09.081 on the 26/3/06...
Andy did Silverstone in 1m 12.365 on the 29th in a Class E/D* car so he aint that bad and the chassis isn't that bad either... As i'm thinking that that RS1800 has either an 1800cc BDA or a 2000ccBDA in it, not a 1600cc 8 valver like Andy.

We will keep pluging away at Andy's car... and it will get better and better

he was certainly working hard going through sear, you could see it twiching back and forth as andy wound the lock on and off several times each lap, although he looked to carry as much corner speed as the front wheel drive stuff.

[retro_msport]

Al.... got me cars and classes mixed up for Les... His lap record at Silverstone is in a Mk1 ... the Mk2 is the RS1800,
Whats he running in the Mk1 ... and please say it at least a 1600 not a 1300GT

Dave, Thanks - the cheque's in the post !

Sorry I wasnt with you guys.will be out with you next time round,looks like I missed a lot of fun!

Group 1 Touring cars (plenty of restrictions like wheel size, tyres, single carb I believe so maybe not a good comparison) the site is showing record holder as Stephen Cripps in an RS2000 Mk1 at 1.23.7 in 2005 but I am sure Steve Primett (spelling?) can better that now as this was 2005 and it rained then and rained in 2006 so not really a good guage. I am just going by the way Stephen came past me at Thruxton when I was out for an afternoon cruise all on me own in class A the other week, they were flying, I think Rob knows more about Stephen's car.

Actually correction there these records were prior to 2005 and it was torrentual 2005 and 2006 so I would not go too much by that.

[R59]

Mark Primett's car is a "RS2000" in that it has the crossmember between the rear arches, as per the last Mk1's. IIRC that happened somewhere around 1974, but was used in earlier AVO builds (RS1600?)
Therefore, it has the longer, more vertical (almost) shocks.

The rest of the car is as per the Ford AVO prep manual, and was built with meticulous precision.

And Mr Primett is getting quicker with experience.

Correctamondo

[R59]

What diff ratio?

[andypipe]

4.44:1. I was pullin 8500 at the braking point on the revitt straight. Cant go any higher, and havent got the budget for another built up lsd

[Al Weyman]

Put some taller tires on :-)
