So I have been driving my truck a little. Very lightly, havent even gotten into the throttle at all. I stop and everything under the hood feels very hot. The AC drier actually looks bulged to me. When I stopped the truck it was reading 420, then cooled down to 320. Anybody else having this problem. I though it was far enough away from the DP. I couldn't imagine what it would get up to when I srart building boost.

 

I'd pull that wrap off, put a layer of ceramic fiber on the DP then rewrap it to hold it in place. It's not gonna get hot after that.
My turbo blankets were 1" ceramic and I could drive for hours, pop the hood and hold my hand on the exhaust housings.

 

Do you have a blanket on your turbo? You might think about putting that factory insulation back on the dryer. DEI makes the heat reflective tape that I wrapped my AC line and dryer insulation with. I could just be imagining things, but I think it made the AC blow cooler air.

Oh and you need to change the batteries in your thermometer too

 

That AC dryer does look weird.

Personally, I think my underhood temps were higher with my old SS 1 7/8" headers than with my current setup (DP wrapped in DEI Titanium and turbo blanket) on gasoline. But the underhood temps were still high. When I switched to E85 the underhood temps went way down.

 

Damn thats hot. Im amazed its even working. Normally that suckers a couple hundred degrees cooler than yours lol.

 

i have my DP double wrapped and a turbo blanket, never had any problems.

 

I do have a blanket on the turbo. Im going to have to look into that ceramic stuff, maybe I will even get the DP ceramic coated.

 

Here is what it was like right after I stopped driving. It is hard to see, but the laser is on the drier, not the DP.

 

For some reason it never had the insulation on it that I see some trucks with.

 

holy smokes thats hot. hows the overflow tank doing BTW with the heat? thought there was some insulation wrap you could put on it ive seen in some engine bays.
