It's interesting how much the air heats up due to the supercharger.
My numbers might vary since I'm at around 6-7000 feet of elevation, but running a 3.12in pulley, I'm making 10psi above 7300rpm, and just doing a couple pulls on the street my IAT's have gotten as high as 180f, with the iat sensor in my chargepipe. This is with ambient temps of about 50f.

Currently I'm on full e85, or I guess e70 since that's what it ends up testing at, but I'm planning on running the water to air manifold that stagefp should be releasing soon.
