I have heard that a good way to "ballpark" your cam timing is to put a compression gauge on your engine and adjust the cam timing for maximum cylinder pressure. Is this a decent backyard method to get the timing close?

That is the way I set mine up, I will test that theory this weekend on the dyno.

Not acceptable method.

Use degree wheel with piece of stiff wire for pointer and dial indicator, piston stop. Google every where else for details on how to "read" a cam to determine where camshaft centerline is at.

Please post results.

I'd be interested to see what advancing/retarding the cam does to EGT's as well (do you have an EGT guage to monitor that)?

I will do 20psi 25psi then open dump and then play w cam timing on the last run. I do have egt, but I am no sure how to datalog at the dyno, maybe just put a camcorder in there. I am getting a data logger fom innovatemotorsports in a bit too.

One the runs just write down what max EGT was during each pull. That should suffice. Good luck.
