Companies don't quote wheel horsepower. So if you have seen someone post that a stock m3 puts down 370whp, best thing to do is get you car on the same dyno and see what it puts down. Or at the very least get a pull on the same brand dyno, but even same brands will put down different numbers.

Purpose of this post was really just to illustrate how much of a difference there can be between dynos. They are a tuning tool.

But still, it is fun to say I have 404whp, even if that number on its own is somewhat meaningless.

Fwiw, this guy put down 350whp stock on a dynojet.
