Its all in the feel.. You'll know. Key is to minimize wheels spin as much as possible..

I'd be way to scared to do a redline launch on a bolt on car.. Just because it might **** something up pretty bad.

Have to brake things to find the limit ........the old adage "gotta pay to play" comes to mind as well.

With 305/35/18 555R's, ~18psi, slight feathering then full engagement, 4-4.5k rpm launches, consistent 1.75-1.85 60' (as long as the clutch holds up)

555R drag radials or regular 555r street tires? I had the street tires and they are/were junk.

You would definately get a hard launch at 850 rpm. Actually you really need to take in many factors, one of which is the tires. You want as much traction as posible and end up in a good area as far as your hp/torque curves, that will vary greatly with different setups.

The NT555R's are the drag radials. I believe the streets are NT555's.
