I've seen owners claim healthy engines making 415-420whp so like 480bhp at the crank.
I noticed this mostly in the latest IND thread on the new M2 where the guy said it's making 547bhp at the crank...
Then, we come to the UK, which I know is much harsher on the results but the same car will be dyno'd here and get similar, if not the same numbers, yet they will be crank BHP so a 405bhp M2 Comp will be like 360 at the wheels.
What is going on here?

the more you know, the less they know
i don't believe any of these numbers
drag race and show me real life straight line, locked in gear, turbo lag, etc
still doesn't tell you how it drives etc etc
