WHP is a much better indicator particularly if youre comparing multiple runs (stock vs. Modified) on the same dyno.

Because other countries like the EU countries, they use bhp as a measure of power.
whp is just a calculation from a particular brand of dyno...hence why you get different whp numbers between a mustang dyno and a dynojet even though there both in whp.
I just gave numbers in bhp since the OP understand power in bhp and not whp.
but end of the day bhp or whp doesnt matter long as you know the delta between your mods based on the same dyno. |
My point is, you can't even get BHP without measuring output at the flywheel. And unless you're ripping the motor our, you won't get that.
Most dynos people use are going to give you WHP. If they show BHP, it's just a calculation on assumed drive train loss, which isn't consistent.
Agree it doesn't matter for comparison, but you also have to assume that the dyno operator didn't adjust the drive train loss percentage.
