Here's what I'm saying. I have the R1 package and the temps got to almost 140 and the WHP maxed out at 535 and dropped off way before redline. We are going to try a larger heat exchanger and a cooler box in the trunk to see how much more WHP we can get with the temps down.
I didn't do a baseline Dyno before the R1 installation....I know.....

On my CLS55 intake air temps were much higher at like 158 on a full throttle run! Seems like a big improvement in the stock cooling setup over the 55K engine.

Just did a run with the Renntech R1 software before installing the IC mods. Temps went up to 140 with ambience temperatures here around 86F...

Now you're making me think twice about installing it. What were your ambient temps when u got 137?
