guesstimate on horse power
Larry Williams November 12th 2010, 7:04 pm
my new toy a pump gas 466 had 460 hp on a chassis dyno. Any knowledgable guesses as to flywheel horsepower?

That's exactly what they will be ... GUESSES.
A chassis dyno is a good tool for tuning. No two are ever the same or comparable to anything else.

I agree considering what I understand a 20 - 30% factor

Depending on trans, convertor, gearing, which dyno, how it's programed etc. Add 10-20%...... But that's a guess too.

82 - 87 % of flywheel hp hits the ground on most setups
