A turbocharger is a heat engine, keeping the heat in the hot side improves it's efficiency.

I work on large marine engines, all of them have insulation (lagging) on the hot side of the turbocharger. They do it for a good reason. I suspect that automobile companies don't lag the hot side of the turbocharger to save money.

One of the first things I did to my MINI was to put the WMW turbo wrap on it. It fits under the stock heatshield and is nearly invisible. The insulation has been there for almost five years, with no problems.

How hard was it to install. Is it an item the dealor is going to have kittens over concerning my warranty? Also, did it make a significant differance in your hood/air scoop temp?

it is pretty easy to install. the hardest part form was to get the screws started on the front of the heat shield, I couldn't get my hand between the turbo charger heat shield and the radiator. I asked my wife to try it and she got it started with no problem.

One of the reviews of Way's turbo wrap says that they measured a 25 degree drop in under hood temperatures with the turbo wrap.

My dealer has never mentioned it, when I've brought it in for service.

Turbo head shield?

Heat is energy which is transferred to the turbine. This is power.

I had this insulation tape I use on my large sportbikes. Its trick stuff shame hiding it underneath, I used it on the underbelly of my AEM heat shield. Had a large scrap after doing my bike. 675 f insulation factor. Its net benefit probably limited.

I second Systemlord's comment. A ceramic coating is an excellent thermal insulator as ceramic is a very poor conductor of heat. For example, the superalloy turbine blades on the hot section of jet engines are coated with a ceramic thermal barrier coating (TBC) to allow operating temperatures to reach 1200 C! And of course Formula 1 engine exhaust components are nowadays are coated with ceramic.
Oops, looks like the materials engineer in me slipped out!

Anyone just use header wrap ? I like the alta idea but again it's over priced like most of their items.
Heat is energy. This heat (energy) is used to spool the turbine. The more heat the faster it spools.

I thought they've gone from ceramic coatings to iconel and other super alloys?
