I have a single pass gallon "super" cooler and my IAT's on the street are 20º over ambient. I don't know what's going on but I'm going back to the stock H/E to find out. With the super H/E I see 180º peak IAT's. I never logged with the stock H/E so let's see what happens. After I switch and learn what I can, water/meth injection is planned. My real motivation are my ECT's. I hope to lower them some by uncovering the radiator and even more with the water injection. I've often wondered if a stronger pump would lower the IAT's, now we'll learn something.
