I'm off to SantaPod next week, long story short, promised a mate who's been building his (B5) S4 into something special (480bhp/500lbs) a match up.. Not wanting to let loose on the public highway I thought Santapod would be the perfect place.

I realise pulling away on a 1/4 mile run puts alot of strain on your car (996TT), also mines mine remapped etc so even more strain.

Can anyone give advice on the best way to start your 1/4 mile run?

In most cars I have raced 4000 rpm and dump the clutch. I do not mean side step it just bang it in quick. Hope this helps.

In my TT (stock) I find about this exact method works very well. Espcially to upset Ferrari 360 owners biggrin

4k rpm and let up the clutch very quickly. You will get the smell of burning clutch though, so probably not to be done too many times unless you have deep pockets. I have only done it once and I don't think I will do it quite that aggressively again.

But for those TT owners out there who haven't I think you should, just once. The car is phenomenal the way all 4 wheels rip into the tarmac and literally catapult you forward. I thought there would be some wheel slip, but there is none at all. It really just accelerated stupidly hard. Amazing car!

I done a few in my 996c4, which felt fine, but with 150+ hp/lbs more I wondered if you went gentle to start then once rolling go for it...

If you get a bit of wheelspin, it's much nicer on the rest of the mechanicals! You don't want to be doing too many hard drag starts unless you want to take out the clutch, gearbox, diff, prop etc (speaking generically not just about 911s).

GuyVert, let me know when you're going and I'll head out there too. I was there a couple weeks ago and was destroying everything out there (there wasn't much). If you dump the clutch at 4000 rpm you'll get massive wheel hop which is not a good thing. Honestly I found that the best short times (1.8x 60') were had by slipping the clutch out at 3000 or so and then getting into it once you establish traction. Lowering the tire pressures to 25psi all around helps as well, and avoid the water at all cost.

For these quick starts, dropping the clutch and all that....should you turn the PSM off?

Same. If you don't have too much HP, you can transbrake it to build boost off the line. The 997TT does this and is faster to 60 (stock) than the manual.

Before I turned my track car into a manual I did one sprint as an auto and blew everyone away to 64ft by holding the car full throttle on the brakes on the line.... then light goes green, lift off the brake and gone.....
Obviously not good for the transmission but it was coming out anyway smile

Now it's 3700RPM and let it in progressively until its in and away you go, if you sidesep it will slip badly and go nowhere, although it not a Porsche!

The thought of spanking my car up Santa Pod makes me shudder. I'd be apologising to it for weeks, if not months. Hell, I apologise to it profusely even if I miss a gear shift.

I have once and then only by accident done a real sling shot get-away. I pulled up at the lights in the 'wrong lane' only to see a supra turbo thing in the correct lane. 3500rpm, off the side of the clutch and the car literally exploded off the line. No wheelspin, bang, second gear and gone. Never done it since. Made a sound like a shot gun going off. Scared the sh*t out of me as i'd only had the car two weeks.
