I find with my car its way way WAY faster to launch harder. I.e at higher RPM even if you spin ( alot ) at the line,
it quicker.
If you launch too low, about 2500 - 3000 rpm, it might bog, and its really not in its power range.
I launch at 3500 rpm, and just drop the clutch, as soon as i feel i have traction i plant my foot.
This is for the E46 thought.
