Well. I took a gamble and lost.. took a stock max4 and put the Pro Stock starter Kit on it I have been trying to sell.. made 2 passes with just pipes and carbs. not bad... spinning around 9300rpm. then put the RPC box on her with a 90 degree chip with some where around a 10,400 rev. limiter. It made it threw the 330foot lights a full second faster and I just started smiling looked at the tach it was past 10,200 then the crank went out of phase about the 660 mark. OPps. rolled the dice. ran out of time to weld cranks. ran it and lost...lol AmSnow ended up a rain out so in hindsight I didn't`t miss to much.
