Why the TR7 in particular?The carrera 3.2 that is in the pics went really well aswell and you could tell he was an old hand at racing,i reckon there will be a few dices with him this year..
The laptimes on Paz's link give me some hope to chase,check out fastest laptimes of the cars that finished just need some consistance,got some ideas for the car that will hopefully bear fruit.Fingers crossed.

1) Slowly raise the revs
2) When it gets to 2.5K step off the clutch like you would on a normal everyday smooth and gentle gear change
3) Hold a constant throttle until the car stops dancing then full throttle.
Note when I did all those test launch runs a couple of years back if you get a touch to much wheelspin or the car doesn't dance a little (it will then bog a touch) the result is a 0-60 more like 7 to 7.5 seconds, very dependent on surface. TBH I found this amazingly frustrating as you either nail it or get a duff launch. If more grip add some revs so the 3K revs idea sounds ideal if more grip then road tyres on a grippy surface.
Once again well done Mark.

The launching off the line thing deffo needs some practice,maybe not too much as when i get my new clutch i dont want to ruin it straight away!but will have a look at the technique you describe Neil.The clutch was deffo slipping by the end of the 40 min race i could hear it as i tried to lay in the power,i was looking at the stopwatch in the car thinking" wave the fiddlesticking flag before my clutch fails!"
It lasted fine in the second race as it had time to cool right down but it was hammered when i mislaunched the first time, someone commented that there were bits of clutch particles all over the engine....
Thanks Scott,it was a dream of mine to race the turbo more than any other car it is a unique car i reckon especially in its day,there are some tracks i reckon where it could do better the esses at the end of the back straight at snett are tricky because of the gearing and keeping it on boost so a bigger track might yield some good results maybe?Plans for the rest of the season are just do as well as i can,i am quite focused on it,maybe a bit too much,there is so much to think about its pretty involving,the preparation of the car the logistics of it all hopefully will become more second nature..
One thing i have learned reversing a trailer with a car on is beyond me[]

[] Funny you say that I worry more about driving with the trailer then anything else. One thing I have decided for sure is that I won't be buying a trailer this year, rent them per weekend instead.

p.s. I'm no expert but the 944 turbo is probably the hardest cars to launch I've ever driven. I tend to hold the revs quite high and let in the clutch quite quickly moving your foot to 'say' 2/3rd's throttle at the same time. If you get it just right the wheels slip slightly and are just re-gaining traction as the turbo spools. It sounds very scrabbly but feels smooth in the car and gets you 0-40 very cleanly.

I've also heard good things about another US company called Southbend clutches. http://www.southbendclutch.com/aboutus.html
I would also concur with Scott in saying that a stock 951 with an S2 crown wheel and pinion really transforms the car on road or track. I have had this for well over a year and wouldn't go back to a stock transmission ratio unless I raced on very long, fast circuits or did a lot of long distance travelling. It reduces your overall final drive ratio by approx. 15% but it truly livens up the car considerably. It just seems to place you more in the 'meat' of the engine's power spot. It can mean that you change gears more often which is not always desirable, but overall I wouldn't go back. On a large capacity 3L plus motor, then I'd say stick with the stock gearing or something else, but for a 2.5L where you are racing on rpms rather than mostly tq, then seriously consider the change...or better still, get another tranny. Excuse my ignorance, but what LSD unit do you have also?
you might find reversing with the trailer easier if you snake it a bit deliberately, curve it left and right a little as you reverse and it makes it easier to know which way to turn. Or practice by reversing boats down your nearest slipway on a sunny bank holiday

Thanks Patrick,will have a look,really not sure of what to do at all....[&:]The LSD is standard Turbo S,works really well though.
Did a day at Silverstone today with my dad and Brother on the National circuit,had some lessons aswell,really picked up a couple of pointers and fundamental fixes i reckon.My car needs new front discs now really badly they just about go through the calipers still,totally warped but have never faded or failed to bring the car up sharpish.Front tyres shredded too,front left tyre is comedy[]
