Does this dyno result seem?

I posted this on the CL forum too, but the threads tend to be slow there....

Anybody have a S600 dyno to compare this to?

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.....

Seems pretty healthy to me. Either way, you're still making more than advertised power. 508 ft-lbs would be more than 600 at the crank.

You are good. CL600 Powerchipped tuned several years ago started at the same 420HP and 500TQ and went to 470HP and 575TQ after tuning.

I'll be dynoing my new S600 soon...will post the results here. I remember Ben Treynor posting a baseline run of 480 rwhp in his 03 S600, but that was probably not SAE corrected.

Did you put the car in dyno mode?

Renntech did the dyno and I saw that they did put it into dyno mode.

The air temp was 94 that day too, that and altitude are big factors in sapping power.
There was a recent test in a mag of supercars where they were stuggling to get the expected performance figures due to the high temps. that day.
Plus, it's inevitable to get a slight dif, from engine to engine.

What correction factor did they use, if any? SAE or STD?
