Only tested in hot weather 84-98 deg. I run about 28 to 32 degress over ambient. So at 86deg. last Saturday ,, I would run 117 IAT but after a few WOT,, it would average about 122 , once it cooled back down.

OK thanks but I need to know the temps before the I/C .... or alternatively how much the I/C reduces temps...

Sorry, I knew it was a 50/50 chance on the reply.. I was not sure if you meant before going into the I/C or before you install the I/C.. I posted the later..

I also look forward to seeing this information, as well. I would like to run a system that is at least 10-15 over ambient, without adding a big ice chest in the trunk..

I think IAT's are around 80deg C, I/C takes off maybe 40deg C, so I think we should be in the region of 120deg C.

Enough to flash water injection to steam!!!

But need to make sure.

Wow, neat concept. i thought they spiked up to about 130? and then fell again. That would definitely be in the gaseous zone, no? What are you gonna do, distill it? LOL!!!

Coming out of the kompressor it is 110-120F above ambient with stock 11.6 psi. After IC it is 30-40F above ambient.

At 14.5 psi on boosted cars it is 160-170F above ambient. Out of IC it is 50-70F above ambient.
