My E63 Dyno experience...


Seriously though,05Venom's E63 was running 12.1x's@116mph+ so all the cars are pretty close.The extra .10sec may/may not have been driver related but being these cars are basically step on the gas&go who knows
2nd ... I have the 7 speed in my SLK55 and the loss from crank to rear wheel is only 15.49%. I did multiple dyno runs ... this loss was on a Dynojet.
Mercedes told me to bring my 08 E63 in after 2000 miles for a tune . Tell u the truth it feels like its holding back .
You hear peeps dynoing stock e63's at 420-430hp but i think its the dyno Or they are testing a car that is hot . im going again saturday and im gonna yank the filters and let the car test cool . hope the oil reads in the 60c range or lower . i heard a light rim and tire package will also increase the final numbers too .

Placed a big fan in the front, 91 oct fuel, dyno mode, manual mode in 4th gear.
Two pulls, both in the 364 range. The air fuel ratio quiet a bid on the lean side
I posted the dyno graph on the CLK section

If these guys running dyno tests have 91 octane (I think that was mentioned in this thread) that would cost maybe 5% of the spec'd power?
Altitude hurts too. I live at 3200'/1000m and I know there is 10% lower air pressure here than sea level. My E63 had a much nicer growl at sea level than it does here.

as my source on the matter.
If I were you i'd take mine back and ask why you have approximately 336KW at the flywheel....
