I've been using header wrap with satisfaction for a few months (In fact my car had a small oil fire, and started leaking oil again but no fire thanks to the header wrap!, now fixing the leak before something happens). Anyway, I like header wrap, it reduces engine comp. temperatures greatly, I want to wrap my turbo too since it gets hotter with the headers wrapped, and radiates a lot heat into the intake. Trouble is I don't want to spend $90 doing it, anybody know where I can get some turbo wrap for cheaper than that (I'm going to do the crossover pipe again too, there's too much oil over it).

Thermotec makes a boot that fits over the hot side. IIRC, it was like $50. Wrapping it would not be easy. I decided to do all but the housing.

Do you have a link to a seller that'll let me buy it for around that price? I'm pulling the crossover and the intake (oil pan gasket), so access would be improved significantly...

For that price, you might as well get it ceramic coated on the inside & outside. These coatings perform much better than the wraps too...

I used the Thermotec hot side wrap. It's awesome. There's almost no heat given off of the turbo. I was amazed.

You have to cut the piece in a sort of triangle which depends on the measurements of your hot side.

Then you use the stainless wire and thread the sides.

Then you wrap around and pull each side tight. Pretty simple actually.

I've got the usual Thermotec wrap on my turbo down pipe, and on the pipe feeding up to the turbo. I didn't use it below the car becuase I drive the car in the rain and water screws up the wrapping over time.

I must say, that with these 3 things wrapped, there's virtually NO heat under the intake manifold.

Just tonight literally stuck my hand underneath the intake manifold becauase I couldn't believe that there was no heat.

DO IT!

Do you know where I can get this stuff?

Ahmet, you used to be able to buy it online directly from them but I think now you have to get it from vendors. I know Summitt Racing and I think Jegs sell it on their web page, search for turbo wrap.

I used regular 1.5-2" wrap to do the turbo hot side and down pipe and it worked quite well. I did that while the engine was out of the car though so access was not a factor.

I used the Thero-Tec blanket kit from Summit and it does a decent job.

Lindsey Racing has a nice section of this stuff on their website.

Thanks for the responses... I wonder if I can make something myself using some sheet aluminum and fiberglass...

I was planning on wrapping the headers, crossover, turbo and downpipe. Ya know reduce some temps, kill some lag and help keep the heat off the turbo cartrage and bearings. I was concerned aabout cracking something with the added heat, most aftermarket header makers void the warranty with the use of wraps due to added heat stress. Anyone have any longterm experience?

"I wonder if I can make something myself using some sheet aluminum and fiberglass..."

You want to use steel for heat-shields since it's a better insulator than aluminum (conducts heat 3-5x slower than aluminum). Titanium would be even better. I've drilled some titanium bar stock where it's glowing red-hot in the center and I could hold it without feeling any heat at all.

Anyone have any experience with the silicon-foam insulator? I think they called it Air-gel or something like that?

one thing I wondered about wrapping things: Where does the heat go? If the the general idea is to deflect the heat and stop the metal from giving off heat to the air around it, doesn't this mean that whatever's inside is going to stay hotter? This might be good for the things around the item (turbo, header, pipe, etc. But doesn't it mean that the item itself will stay at a higher temperature for longer?

I'm no physics expert, but it seems like the heat has to go somewhere. Of course, maybe the item stays cooler because the area around it has less ambient heat, and therefor helps cool it. If wrapping helps everything, why not wrap every single piece on the car that could get hot! Sorry if I'm ignorant on this one.

The extra heat goes out the exhaust.. where you want it.
