Ive been having a problem with bogging off of the line. I've tried several different launch RPM's (stalling from 1400-3000 ) and methods of launching and i still seem to bog. My car will spin and the tach will hit about 4500rpm's and then i will get wheel hop and it will drop under 4000. Whats the deal? I am about to spray a 75 shot out of the hole to see what it does. Any suggestions?
