It’s all about keeping control.
As much throttle as you can and lifting the clutch as quick as you can but without the tyres breaking traction too much.
Easy to say but when you’re on the line and the adrenaline has started it is all too easy to give full throttle and dump the clutch.
Once you have the hang of it it is relatively easy to keep all your times within 1 – 1.5 tenths of a second of each other .

Thinking the clutch will be the weak link in our case.phazed said:
I run a McLeod twin.
We have used them on other cars (we built a Mk2 Jaguar with XKR supercharged V8 & Tremec T56 Magnum gearbox, for example) and they seem like great clutches - light operation but with great torque rating.I do prefer the clutch to be the weak link if possible - safest and least expensive failure mode.

From memory, there have been more broken drive shafts/CVs than broken clutches. That’s with standard kit fitted. If you don’t gave suitable drive shaft spares, I do have one, and while I don’t plan to be at Santa Plod, I can probably get it to one of those who is going. I pass Alex’s gaff at least twice a week, and he is frequently seen at such events, taking grief for his six year LS twin turbo build duration.
Interesting. I have personally not broken a driveshaft or CV joint but probably not driven them hard enough by the sounds of it! We can bring a spare driveshaft and CV joints if you think it worthwhile, thank you for your offer though.Would be good if you could make it too, would be nice to meet you.I have Dave Mac shafts now so no problem. I snapped a driveshaft at York once and replace it with a spare assembly within an hour and won the next race.
I will be in mu van and have plenty of tools. I also have a driveshaft so we are covered. It takes at least 380 bhp and sticky drag tyres to break a shaft normally so shouldn't be a problem.

just curious Derek ,
i re engineered my 2500M stub axles and half shafts using jag stubs and prop shafts ,when your shaft broke , did the car turn sharply to one side ? i always used this idea as provocation for going to the trouble of changing it all .

I had this on a Supra after changing the LSD. It was faulty and was locking up. i re engineered my 2500M stub axles and half shafts using jag stubs and prop shafts ,when your shaft broke , did the car turn sharply to one side ? i always used this idea as provocation for going to the trouble of changing it all .

I just lost complete drive and rolled to a stop!
That was the run after I did a 1.65 seconds, 0–60 ft.
Think of it as nothing more than a traffic light Grand Prix but in this case you're just concentrating so much more on the balance of the clutch and throttle to give minimal wheelspin, nothing more.
I am sure novices mess up because of the adrenaline, the pressure of being the focus of attention and the novelty of being at the line!
