This is on the stock sensor for short runs...so take that for what it is.

Extended runs (ie. loading the engine with the brakes and staying in boost for a long period of time around 5K rpm I can see 60-65C) but that is as hot as it gets with no intercooler. And this is on a very hot day 100F.

With the water injection on I have very efficient cooling of the charge and this is with water only. My IAT is never above 40C on an 80F day. W/I is where it is at! It also allows me to cool the engine fluids far more efficiently but there is another thread for that.

I like the CAI idea. Don't know that I would cut up my bumper to do it, but I really like the idea. Which is probably why I have it...
