Default IAT's too high???

I recently installed a MP112 on my truck along with a aeroforce interceptor gauge. According to the gauge my IAT's are in between 150-170 daily driving in stop and go traffic. I dont know if that is normal for this blower and this time of year or not. It has been averaging about 92-95 here during the day. Does anyone else know if this is normal or too hott? The kit came off a hummer so it has a small thick HEX with a 10inch efan on it and still creeps up at a stop. I have water wetter in the reservoir along with dexcool and a little bit of water. INPUT NEEDED. I do not need to be burning up another motor due to this. Thanks!

Make sure that the pump is circulating.

Throw up a pic of your air intake setup. Also, what size pulley are you running?

Its a 3.1 pulley. About 6-7 psi. I did realize my iats cool down ALOT faster and run alot cooler with the hood up so im goin to try to seal up that box around the filter

One of our local tuners (has a mp112 on his truck also) put a meth kit on his truck and said he only noticed 2-5 degree iat differences. Said it cooled off faster and let him run more timing though

In my own research, meth kits didn't do very much for IAT's on MP112 setups. But the boost in octane can help you make more power. So I agree with you there.

I'd start by sealing up that airbox. Your Maggie is gobbling up that under hood air like a fat kid at a buffet. I'd also recommend getting the largest air filter that you can make fit. That little filter is a restriction, and that can make the blower work harder=more heat.

The meth doesn't lower my IAT's by much, but as mentioned it does help with timing. Those IAT's are crazy hot though, in 90 degree temps even after hot lapping at the track I dont see those temps after a full run.
