How to launch a manual on the street?

the way I used do do it (back when I used to do things like this) get the engine up to its peak power band and when the light turns green start slipping the clutch looking for that point of maximum traction and power (when the tires start slipping in a car or when the front wheel starts floating on a bike) keep your RPM's up when the clutch is all the way out SHIFT and do it again (you will beat faster vehicles burn out a lot of clutches and break things)
