I've heard and read differing opinions on this. Some say it's underrated, whilst others think it's dead-on.

Mine did 400rwh with a bad water pump.
400x1.2=480 to the crank, I am not sure about the conversion. But it's what I've heard.

Evosport dyno'd a stock E55 - there's a thread about it on the forums about it - I believe they dyno'd at around 520 crank.

Evosports dyno numbers tend to be a little higher than seen on other dynos. The E55's produce around 15rwhp less than the S/SL55's on average from what I have seen. I think the numbers are dead on.

As for what the E55 really puts out at the crank.... all that matters is what it puts out the rear wheel. Pick a drivetrain loss % and you can pretty much make it whatever you want. I usually use 15 - 17%, but I don't think anyone on this board knows what it really is

It's very impressive, nonetheless.
Thanks for the informative replies.

Using a 18% loss factor,
422.7 RWHP equates to 515 Crank HP.
481.3 RWTQ equates to 586 Crank TQ.
RWHP / 82 * 100 = x
I have been told DynoJet's sometimes show approx 10% greater #'s than in reality.
