On my 01 the prior owner put the boost gauge input just after the turbo pipe before the intercooler. I am in the process of ordering the IPT boost gauge install kit with their map mod. I was debating on putting a intake temp gauge in its old spot. just wondering how hot does the air get after the turbo before the cooler. thanks

It can get up to the 300º-400º range IIRC.

You will read a lb or 2 higher on the hotside because of the drop across the intercooler.

With my stock turbo I was seeing well into the 425*F range at the compressor discharge.

Personally I would put the boost gauge and MAP line at the turbo output. I like to see what boost the turbo is making as thats what keeps thrust bearings alive. Also on my OBS truck after the IC install I reduced the lag alot by moving the MAP line. It may not be much of a gain on the SD but the smaller exhuast housing but I bet it would make some difference.

It can get stupid hot. Depends on the Pressure Ratio and the compressor efficiency at that pressure/flow.

Black Widow had a graph that showed the boosted air entering the intercooler at 485*.

heard numbers here between 300-485 wouldnt that,melt the boots ????

Nope. Thats why they are hi-temp silicone.

Combine high temperature with high pressure on even a good silicone coupler and you will get a coupler that's in it's third trimester, lol.

Push it a little harder past that and you'll get an oily C-section :doh:

The little 38R "Impregnated" more than one silicone coupler on the hot side when it was a single with flames rolling down the CAC tubes at 40lbs of boost with BD's litin it's ass up 24-7.

In excess of 500 degrees is not unheard of. And if you start running some serious boost you can get truly ludacris temps. Think what the IAT would be on a Mod class truck without the water on...

I noticed just this past weekend where a cable coming close to the intake on Double Overtime was all melted on the side right where it passed the intake manifold....
