That above graph sums up perfectly why -5 cars will still be quicker at the strip than the RS'
All the antilag/launch control in the world wont keep the tyres or clutch slipping to keep the engine at 8000rpm unless you have 1000+hp, the revs will drop back and it will fall off boost
The other thing the graphs wont show is how long the RS's will take to come back on between gearshifts, Piggaz's car is near on instant, infact it was better than my old car, which I felt was about as instant as a turbo could possibly be.
Ive been in a RS powered GTR once, and I was counting the seconds for boost to come between gearshifts, it reminded my of a mates GTR that had a T88-38gk on it, but without the 1000hp hit up top
another mate had a 300zx with 2540's (near enough the same as RS') it was also laggy, and it had mega $$$ heads and manifolds on it, it was slower round QR than 300zx's with standard turbos and more weight
