hi guys,

My question is related to this:

Is it possible to ACCURATELY determine engine power from a dyno reading/graph. I have always believed that only power at wheels can be calculated on the dyno and engine power is ESTIMATED based on 25 - 30% drivetrain power loss.

Am I correct in saying that engine power can only be estimated from a dyno unless you rip out the engine and dyno it alone on a "special" dyno?

100% correct, flywheel power is only estimated unless pulled from car!

The load from trans/axle is different in every vehicle & can only be estimated.

I don't even care about dyno output as they can never simulate the real thing, they'd have to be in a wind tunnel!

They're just good for tuning.
