Hey all.

Does anyone know how much, if any, air intake temperature effects power on the dyno? Additionally, does anyone one have experience with differences, with different temperatures.

For example, I just got my car tuned yesterday. I just added some QTP HVMCs, and I DID have a measurable increase, although, admittedly, I was hoping for more. Regardless, I had the standard QTPs, when tuned before, and the only change was going to the HVMCs. Anyways, when dyno' d with the standard collectors, the air intake temperature was only like 78*. This time, with the HVMCs, the temperatures were near 110*. I understand the cooler the air, the more dense, but, more than anything, I suppose I am just trying to justify the added expense in the HVMCs, and additional labor I invested.

Thanks for your help!

Chuck

Depends on what the IAT was...at a certain point, there are tables that will pull timing (how much depends on what it was reading).
