I've a question: If the engine can handle 35 degrees total advance at 2500rpm then would it not be able to handle even more at higher revs and give more power?

Julian.

Blue is talking about a light race car , your Jenson is a different ball game , if you don't believe what i'm saying , maybe some of the other guys will chime in.

Low compression 'smog' motors can handle more spark advance , bearing in mind you're running around 10:1 static compression , chances are it will detonate with anything more than 38* total advance @ 3000 rpm , on pump gas.

10:5.1 compression is the max you want to run for pump gas , bearing in mind you want somewhere around 40 thou quench , any more than this your gonna run the risk of detonation or haveing to run high octane fuel.

Don't know why you would be concerned Pete , as the car will never see the street , could'nt be easier , more bricks you lay means higher octane you can go.

Pete , dynamic compression will never be higher than static compression , no matter what the cam profile may be (IVC) , blowers , turbos , nitrous not included.
