There is also a variance between cars.

My 01 would only sidestep once If you tried again soonafter you burned up the clutch. My 00 will do it with much more ease and frequency ...

The 00 also feels like it has some gravel in the gearbox when compared to the 01 which is buttery smooth.

i didn't dump the clutch.. that's what i figured..
wisconsin.. i know you have launched plenty.. is the tire squeal in my first launch what should happen, or should there be no tire marks?
yes, you should hear tire squeal. as for skid marks, that has nothing to do with whether you did it right or not, vs the type of surface you are on.

see the link in the bottom of my sig. it has a video that shows me launching pretty well.

excellent case in point about each car being different. my 01 could take clutch dumps minutes apart with no problem.

I clutch dump anywhere from 4-10 times per day at each autocross event, stock clutch (and diff) is still holding up at 35k miles. You gotta spin the tires, dont feather the clutch and don't bog.

no. "lose power" is a loose term.

while the torque tends to go down a bit, it's still easily making useable power. so to say that it's "losing power" in the sense that it's hurting acceleration would really be incorrect. redline/fuel cutoff is the optimal shift point.

True that, although peak power is made at 8200, if you were to shift at 8200 and not bring it up to redline you will be at alot lower RPMs in the next gear than if you redlined. Basically your making more power at 8900 than you would be at say 6200.

basically shifting at a higher rpm so that you are in a higher rpm o=in the next gear, leaving you where the power band is in our cars (high rev)
