Does anyone know what the volumetric efficiency is on the hp500 at wot. Or the teague 620hp or similar 502/510/540 combos. Thanks The Ironman.

Come on somone must have some dyno specs on something close to one of theese BBC's All I need is a ballpark figure for some calculations. Thanks, The Ironman.

My dyno sheets don't have volumetric efficiency on them, but when I simulate my 500 HP oval port 502s, the dyno program says 90% V. E. at 5000 RPM. That should be close enough.

I'v seen numbers over 100% with good headers and a single plane manifold.

Thanks, I am thinking that over about 500 hp will require more than an 800cfm carb on a marine engine anyways at ve = 95 or so.
