Thanks Greg, we'll see you in Spartanburg.Originally posted by greg:
Jim Dolan - sorry for the late reply. I'm not sure I understand your question, though.
I'll try again, though, using different words. In my opinion the driver made two errors. His launch was initiated with RPM way too high, which resulted in excessive wheel spin all the way to redline. Because the wheels were spinning, the car was going a LOT slower in 1st at redline than it should have been if it were "hooked up".
And that lead to the second problem. In his 1-2 shift, you can hear the engine slow down OVER TIME to match the rather low revs of the now hooked up 2nd gear. Because the car wasn't going as fast as it should have been going if he redlined in 1st with the wheels hooked up, the rpm difference between 1 & 2 was a lot greater. A proper launch and 1-2 shift would have engaged the clutch much more quickly - you should hear the tires chirp, but you should hear the engine change pitch as if you went from one note to a lower one on a piano - more or less instant - instead of sliding from one to the other like a trombone. That is how clutches get ruined in a hurry.
I can't remember which of the magazines it was, but in one of the March '00 reviews, they said their optimum launch technique was to rev to only about 2000 RPM (if I remember correctly) and to "feed in" the throttle as the clutch pedal was lifted, specifically to AVOID excessive wheel spin.
