Best Turbo heat wrap?

[dblake]

Hey guys and gals. What is the best turbo heat wrap out there? I’m trying to limit the amount of heat coming off my turbo since it’s damaging some lines I installed on that side of the engine bay. I’m assuming most heat comes off the turbo and not the exhaust pipe. Or should I wrap that also. Thanks for the help..

You will probably want a “turbo blanket” vs heat wrap tape for your exhaust housing. Here’s a nice example:

Heat wrap tape would work nicely on the first few feet of downpipe to keep the heat out of your engine bay as well. Summit, jegs, basically any performance shop has that type of material.

I had a manifold and turbo blanket on my 05, and wrapped the first few feet of my downpipe with exhaust wrap. They were made by turbo performance products. Levi's products are top notch.

I’d like to see a real “study” or experiment as to how much cooler these things actually make the engine bay.

From my race bike days, pipe wrap was to keep the exhaust gases hot for quicker evacuation. I wrapped the head pipe on a dirt bike once to try to keep from getting burned because it didn’t have a heat shield. Sure enough, I had a little spill and the bike landed on my leg. It burned the weave pattern right through my pants and branded my leg. I’d say it was as hot or almost as hot as the pipe itself.

On my '05 I pulled over a couple times at the top of a grade where I was holding 1200° pre-turbo and was able to rest my hand on the exhaust manifold blanket. There also wasn't near the heat radiating on the passenger side. I do recall measuring the temp on the outside of the OEM airbox and seeing cooler temps, but I don't recall those numbers...but they are probably somewhere in the TDR archives.

That sounds wonderful, in a retroactive sort of way. I used to tow a travel trailer with a 1983 Jeep Wagoneer Limited. They were called Grand Wagoneers beginning in 1984. It had a 360 V8 which I upgraded with AMC's dual plane intake, a Motorcraft 4350 carburetor and a new catalytic converter. It burned a lot of 91 octane gasoline and put out a lot of heat. It would have been great to have been able to wrap the head pipes with that material, if it had existed and if I had known about it back then. I was getting to the point of having louvers cut into the front fenders behind the wheels when I gave up and bought the 1996 CTD. We went from 5 mpg to 16, and never looked back. (The Waggy was sure comfy, though.)

Sorry, no real study. I installed a custom heat blanket system from Advanced Thermal Products in Irvine, CA in 2015 (about 140,000 miles ago). The valve cover, exhaust manifold, turbo, oil pan, and the down pipe past the middle part of the transmission were all covered. No heat measurements with a thermometer, but I tested under hood temperatures in the same manner @AH64ID did - with the same results. There was far less heat buildup in the engine compartment. First thing my wife commented on was that the floor on her side never got hot again - no matter how hot the ambient temperature nor how long the grade.

Thanks for the help. I ordered one of these.
