    Can a wild cam timed mild, beat a timed mild cam timed wild?

    sorry, thats my attempt at being funny...

    Scouger your thinking of ignition timing controlled by ecu. But yeah I agree, factory figures are usually best. You can swing the timing on the dyno, but usually your talking altering a few bhp peak for a few bhp mid...or smoothing out a torque curve.

    Could you tell me all specs of a genuine Williams cam? And I'm wondering what does the timing open-close mean?
    Thanks!

    I usually look at the lift at TDC and duration for the inlet and exhaust side before deciding, so my new cams that I have ordered are pretty wild, but not too wild, will still run and idle normally to the point you'd not even know the car is cammed.

    inlet opens 22* before TDC, and closes 62* after BDC, exhaust opens 62* before BDC, closes 22* after TDC.

    so duration would be 22+180+62 = 264*

    same principal with the other e.g. youve given.
