I have an issue with my car currently. I keep breaking belts and popping the bust plate it usually happens right around the 1/8 mile. I am having problems figuring out why it does that. The car is a Top Doorslammer style car with a blown TFX hemi. I checked all the intake valves and none are leaking. The valve springs are also all in descent shape. between 310 and 340. I tried to take less fuel out with the high speed i also raised the rev limiter to make sure it wasn't hitting the limiter but neither helped. More engine data: 500 cui TFX hemi Stage 1 AJPE fuel heads SSI standard helix 14/71 fuel blower (36 OD) Fuel cam cr 9:1 What gives, it is getting old really fast changing belt and bustplates.
