Dyno Chart w/Intake Cam Retarded one Tooth?
The stock cam closes the intake at 45 ABDC
Adding 21 would make this then 66 ABDC
Woods A1 is 58 and Woods 7 is 72 ABDC
For a mildly tuned motor this would be too high.
Retarding the cam would lower cylinder head pressure by 20 - 22 PSI
Compression would have to be raised by 1 to regain PSI.
I think retarding the cam 5-8 degrees for a carb (mildly tuned) motor may have merit.

On stock cams, I can buy that. The turbo is making power at least 1000rpm higher than stock, so it probably fell right into peak power.
Oldmanracing, this post has gone too far! Competitors might start figuring things out! [img]i/expressions/face-icon-small-smile.gif[/img] Nah, it don't matter anyway, nobody is going to buy that many camshafts to optimize duration, lift, lobe centers, ramp rate, etc... Then change their engine a little and have to start the process all over again.
