in regards to an earlier post about inirtial dyno's "guessing" at HP numbers...this stuff makes my blood boil, do you even understand what horsepower is? it is a measure of work done vs time, accelerating a known mass is the most direct way to measure that. if anything, a load bearing dyno is a guess, it relies on calibrations to approximate the load being generated, which varies greatly based on type of resistance/load etc.

Out of respect for the OP, I'd prefer to have this discussion in a different thread about dynos. When I start the official dyno database thread, maybe that would be a good place to discuss it.
