Does this dyno result sound low to you??
1st run...94 degrees, 30.18 in-hg, 3rd gear
419 hp
508 torque
2nd run
404 hp
490 torque
The guy did mention my IAT was at 85 when it should be at 60 so it may be an intercooler pump that is weak or dead. The car does seem slow once it is fully warmed up compared to when it has just reached temp.....

I am assuming these are rear wheel measurements. If so, they seem a little above the factory ratings (493 hp and 590 tq) in the 1st run and are a little below them in the 2nd. Lets say a conservative 20% loss to transmission.
1st Run
419 x 1.2 = 502.8 hp
508 x 1.2 = 609.6 tq
2nd Run
404 x 1.2 = 484.8 hp
490 x 1.2 = 588.0 tq

419 x 1.2 = 502.8 hp

490 x 1.2 = 588.0 tq

Yeah...they do show right at the stock figures, however it seems Mercedes underrates the 600's. For example, a Renntech tech showed me a dyno sheet from an S600 that ran 446rwhp stock (and then 515hp after the ECU/TCU upgrade). That's why I figured I'd post a thread and see what others are pulling.
It was extremely hot the day I dyno'd the car as well so I'm sure that didn't help things. Gotta love Miami!

Miami's a fun place...killer heat in the summer. Mercedes does underrate their motors. Some months ago, a guy with an automobile identical to mine posted rear wheel dyno results which equated to 480 tq, 60 more than MB rates. If I can find some time, I'd like hit a dyno and see what it can do. 480 tq would be real nice.
