Re: Honest Power figures
I don't get much of this. You have a pushrod with 2 valves per pot, 408 cu in, about 6500 rpm peak, a cam, an exhaust so you'll be pushing about 0.415kg/sec of air to get 350kW @ peak revs. That presupposes you have a decent sized throttle body (eg 100mm or dual 68mm), intake ports of about 2400mm^2 and exhaust ports of about 2050mm^2, and failry minor pumping losses.
So how do you expect to get 410kW out of an aesthmatic engine, with poor volumetric efficiency, presumably heads designed for low swirl, on pump fuel?
