Looking for some feedback from anyone who has played around with advancing camshaft timing & retarded ignition timing on a Clevo.
I wanted to try advancing the cam timing to bring the cam on a litle earlier in a run.
2 deg advanced brings the cam timing to exactly what the Crane cam card spec is, the cam is a 528821.
I have tried zero,2,&8 deg advanced, I can go as far a 8 and still have .085 inlet valve to piston clearance.
The engine seemed to get lazy about 400ft with 8deg advanced, so I moved it back to 2adv.
I also wondered if I should try advancing the cam to get the half track times down, then pull timing out with the MSD in the top end.
If its only purpose is for racing, take into consideration how well it hooks and then how well it traps. Advanced cam timing could net you a better hole shot, or it could blow the tires off...
