I have been battling some IAT issues which is preventing me from turning the boost and timing up on my car. I had a smaller intercooler, so I swapped it out for a new 4" Mishimoto large core intercooler. Temps with previous intercooler were 160-170* right before the intake at the top of the 1/4 mile with only 16# boost and 12* timing. After swapping out the intercooler, the temps were down a little bit to 140*-150*, not as much as I was hoping. I had a buddy ride along with me to video the intercooler temps. I installed a gauge that reads pre and post intercooler temps. I was surprised to find that the pre intercooler temps were over 300*, so the intercooler is definitely working! Any idea why the charged air temps are getting so hot? Anyone else had this issue? This is a built 4.6 2V with FF CG fab headers, precision 76/75 CEA turbo. Thanks for any help.
