What is cam overlap and how do you adjust with a thundermax auto tune
Cam overlap is a mechanical design feature and is not adjustable by any means whatsoever after engine assembly is completed (with possible exceptions being extremely sophisticated pure race-only engines and dual overhead cams).What is cam overlap and how do you adjust with a thundermax auto tune
Cam overlap is when both valves (intake & Exhaust) are open. Cain't help you with the Thundermax.
Excellent info prodrag and completely concur. Thanks for filling in the gaps I left open.lift has nothing to do with compression requirments(duration and opening & closing specs determines what compression it should be set at),the .570 likes to be set @ 9.8-1 (10.0 max),second overlap is what it is and cant be "adjusted" with your T-MAX.a S&S .570 is a mild cam and not really seeing why your haveing a problem tuning it.we use ALOT of them and are tuned with no problems
I think your reply was warranted. All you did was ask a simple question.
You want to hear cam overlap? Put your ear at the exit of your muffler. That is where you hear long duration and overlap.I have a stethascope I listened to the Heads.cams.lifters,pushrods,flywheels, all the engine but when I listened to the throttle body putting the stethascope insude without touching the sides I heard the sound whop whop whop is that cam overlap ??
