I clearly wasn't just judging my speeds based on HP alone. did you not see the 3 youtube links i posted?
why would you bother to go into eyeballing acceleration times when you don't know if the race track is flat, or not? Why put them in completely different environments to compare, when you have an actual test between 2 cars one after the other, M4 GTS and GT350R on the same track, on the same day, by the same driver? It's not rocket science.
Fact is, there's just no way that a GT350R will be several clicks slower than a BMW M3 at the end of the straight. Unless the driver totally cocked up the drive.
