72bluebird: Glen; I don't like the stress that would go through drive-train with loading the revs & dumping the clutch, so I just sorta hit the peddle from about 1200 revs & do a double bounce on the clutch to launch out without bogging. At one meeting I did 17 runs & every 60ft time was 2:0-2:06 sec's, so I'm very consistant.
Clutch is a Center-Force Dual-Friction which lasted three years of pretty hard launching. Ram Twin-Plate next time for me.
