It helped a little.

My comparison is suburb to highway to city traffic type driving.

Before the second pump my temp would settle (after fully warming up) to 30 degress above ambient.
Now it stays at about 25 degrees above. When I hit the gas and get a liittle air moving it dips down about 5 degress. Wednesday night drags at BIR so we'll see what happens under boost then. I don't really go flying around on the street too much.So, I think I am seeing minimal gains with the two pumps, but I had them lying around and it was fun to take the bumper off anyway.

Jim's highway IATs are the benchmark for me. WOW!

The fan controller however works great. Hottest day we have had so far this spring has been 78F and my ECT never went over 178F. Highway, traffic, the throttle just seems snappier at a lower temp. I really thought that lowering the engine temp would help with IATs but they settled to the same 30 degrees above regardless (now 25).

32Krazy, let me know if you want to get rid of tha KC, I'll throw that bad boy right in!
