sorry if ive asked this before, but its a little diferent this time. what clutch bells do u have on ur hellfires (if u have 1), and how and where do u drive them?

14 & 15 for track only, i think 14 will still hurt the stock 4.6 for some real top speed, will try 15 tmr

btw note for the front engine bearing for the stock 4.6, mine had just gone bad [:'(]

what are your driving styles? where do u drive and how long does it take to top out with the 13T bell? i dont want it at top rpms for too long cause hpi says it will blow the engine if it stays there for too long, but i do want good acceloration.

i drive very aggressive[>:] imho 14cb will still kill the stock engine at top rev i just killed one (not sure if it's bcos of the front bearing problem or top revs though) but the sound at top rev sounds crying for help[:'(]

i drive at track only, w/ 13cb it will top very if not too quickly

i just bought another set of piston sleeve if it still doesnt last i'll probably skip for a new engine...
