to be honest, a massive chunk of time lost in 0-60 sprints is in the change from 1st to second on a manual box. even a totally perfect shift will be over .25 of a second. plus unless you are running anti-lag or flatshift the turbo will need to spool up again too. ive spent a few years racing turbo'd cars and although i tried using a short ratio gearbox i quickly realised that with a powerful engine (mine is circa 450bhp) you are needing to shift more often and are actually slower 0-60 with the short ratio box was always 4.0 0-60 with the standard box was 3.8  edit: before i got the sensible S8, i nearly bought a SLK tiptronic with 7 (or 8?) forward gears. that would have been awesome ripping through the box

Ah yes, good point about the wheels and tyres. I don't really have enough knowledge about drag racing or tracks and all the asdjustments and parts needed for each type of performance.
Its true I forget that with only 317lbft, and probably only 200lbft from 1000rpm, I don't have grip problems from a standstill. Your RS8 must have over 500lbft I'm guessing. Quote:
Its true manuals lose some time in the shift, but so much is gained in terms of weight and less power loss. Just look at D2 S8, with auto box 0-100 is 6.4s with manual its 5.4s. And Car and driver with a pro driver actually got 4.99s with a B6 S4 essentially same drive train as a S8, so with complete disregard for transmission crazy times can be acheived with a manual car.

500 ft lb I have already at 2700rpm
I did a power test on my RS8 in November 2012 This is my torque and hp in the engine. 1500rpm = 300 ft lb and 80 hk/ps 2000rpm = 350 ft lb and 130 2500rpm = 440 ft lb and 220 3000rpm = 540 ft lb and 310 3500rpm = 610 ft lb and 400 4000rpm = 635 ft lb and 500 Unfortunately, did a piston melt at 4300 rpm because of a bad ecu tune, but I bought another RS6 engine after that and got a good ecu tune that I have been using since then, but I have not tested my engine power again but will do it this summer.

Carry on carry on.... I'm bussy eating popcorn and reading the thread
As of now the car is nicely placed in the garage since MOT expired 01.09.13 Got all the parts needed but with 1 kid in the hospital for the last month there has not been any time to do the Job.. As prob most of you in here there are so many plans... I for now really want an RS2 for keeps but if i manage to get the one i have in sight the 8 has to go... So RS2 or race S8?

The question is what are you going to use the car to?
RS2 is nice to look at but it's no big difference against a much cheaper S2. And for the cost of a RS2 you can buy a much better RS4 or RS6. So if you want a good looking fast all day car then Rs4 or RS6 is your choice. But if you want a track car, well then an race S8 will be a really fun car for less money than an RS car.
