Quote:Eightsix: the timing map sometimes becomes constant or smooth at high rpm, with a fixed max.advance..however big cammed engines can have very irregular VE maps with large fluctuations between 4000 and 8000rpm..you need to adjust your timing too them...maybe just ask Ben what he does for timing and what difference he expects..he probably knows from experience.

I have dropped Ben an email, but havent heard back yet. If I can increase the power by having the timing set properly then fantastic just means I am quicker on track. The car performs well on its current set up, but I know its not perfect. Just want to make an informed descision on which way to go.

Quote:160hp on poorly adjusted timing sounds like 300deg cams and 1200rpm idle. Would be very very difficult to make that kind of power with the stock rev.limit. Get it on a rolling road some time and before that post some vids...carbies sound great.

Its got 288 cams, head skim, idle is lumpy and high. Goes nicley and sounds amazing - taking it to about 8k but pulls beyond and power is stillclimbing. I should have some video footage shortly.

I have no email, please expand on the problem?
