flywheel horse and rear wheel

Thanks BrianT-that is what I am looking for. I am curious to learn and cut through the crap that some "experts" spout about how much less power is made on a chassis dyno compared to an engine dyno. like "chassis is 25% less than flywheel". I know it is not that simple. depends on tranny and rear endand fluids used and more. and I don't like engine dyno testing done for the big bragging number-no air filter, no mufflers, etc. I have not dyno tested my chit, I do it at the Epping 1/4 mile
