Default Re: chassis dyno

My car, running a normally-aspirated VERY MILD 360 Magnum Mopar engine made 260 RWHP on a Dyno Jet dyno, with a 2.76 rear axle ratio.

If I had swapped a 4.56 gear into my car on the spot and had immediately, re-run the test, I am SURE I could have accelerated that inertia roller a lot more quickly.

Would that have altered the "reported" HP output, since it did the same amount of work more quickly?

It should have, or maybe I don't understand physics.... a definite posibility.

If NOT, then how is the Dyno Jet type of computer able to deal with this variance, and give us a legitimate HP number with both rear axle ratios?


Just askin'....
