This is a baseline dyno taken last night by Evosport for my stock C230, manual trans, 5,000 miles. In case it's not clear I got 167.7 max HP and 178.5 max Torque.

I have noticed a nice ach between 3300 and 4200 rpm on all of the plots I have seen. You have a nice head start on me mine pulled 159.6 max HP and 175.1 max torque when I started. But it only had 900 miles on it maybe they losen up a little with more millage.

One thing to consider when comparing dyno pulls is ambient temperature. If one is done at 96 degrees, such as the one renntech posted,and another run is at 70 degrees, there will be a significant difference in results. Same thing can be said for humidity and atmospheric pressure.

Is anyone using a fan to blow air across the intercooler?

renncpe

Good point about the temp. We did run fan but not directly on the intercooler. It was blowing toward the grille with the hood closed, from a distance of about 3-4 feet.

The graph is SAE, so the dyno took correction factors to fix the numbers for variations in humidity, temperature etc.

So technically, if you compare SAE numbers...dyno'ing on a hot day or a cold day shouldn't really matter.

I don’t know if the dyno can correct for ambient temperature and humidly, even so that would still not compensate for the efficiency of the intercooler.

That run is very consistent with the run that Compact Sport Car did, so it is a very good baseline.
