Supercharger & Turbocharger

[Thirdgen89GTA]

1/10 in the "60 ft" is worth 2 tenths in the 1/4....every 100 lbs of dead weight is worth 1/10 in the quarter, and every 1 lb of rotating weight (wheels/tires/rotors,internals etc etc etc) is worth 7 lbs of dead weight in the quarter....

I've always heard .3, but either way launch is important.

Less rotating mass is almost always a good thing. I'd rather have a lighter driveline because I prefer road racing and don't need to hit it hard at launch. I'd rather have the engine gain RPM quicker.
