I have no top speed on the long straights and my temps have shot up. I am assuming that I am heating due to high RPMS. Should I go up to 14t or 15t? I read that someone was running this high of a pinion witha 4.5t 550 motor. Can someone provide their experience?
Start with lower sized pinion that you have available that is bigger than the 12 and check temps again.
What people are running boost etc with there pro4s? I have been hearing about people doing this, gearing down then making up top end with boost, super charger, etc.
