Turbo Blanket

This is all thermal dynamics. 95% of cars do not have forced convection cooling inherent in their design like ours do (functional hood vents). The turbo blanket would remove almost ALL convection cooling (both forced and natural) from the turbine housing. That means that all of that heat is distributed through the manifold to the head through conduction, INCREASING the engine temperature. Usually, this is overcome by the initial DROP in intake temperature, which helps cool the turbo and engine from the inside out, doing slightly better cooling than the blanket does heating. That's why there are minimal gains in almost all cars. But with our cars, and the position of the intake, we aren't taking in air from the engine bay really at all. So if there is no drop in the intake temperature (a turbo blanket isn't going to cool the outside air, where most of our intake air is coming from), then the engine bay will actually get hotter. That is my only point, thinking of this objectively. But like I said, there are differing opinions and this topic is debated often. This is merely my opinion. Feel free to form your own. I was just encouraging everyone to think objectively about it.

You have made a great point. Thanks. blanket will be a waste of money but a scoop that can catch more air will aid in helping the turbo stay cool.

I know this is for turbo blankets but that brings me to the question to ask what of thermal wrap? not for your turbo but for the exhaust manifold and the down pipe?

So Im guessing heat rap may not be a good option. but some are good for up to over 2500 degress.

I have heat wrap on my other car, a JDM Forester T/tb, no problems at all. It is on the exhaust manifolds (headers in US speak ?) and the up-pipe and downpipe. Keeps heat in and that helps the turbo spool and keeps heat out of the engine bay.
I just ignore the youtube video as when did you ever drive a car where the revs were so high at such a constant speed for so long ? For a road car it is a totally irrelevant bit of nothing. If you want to heat wrap then do so.
I shall now retire and put on my tin hat !

lol, Brian I am just throwing cons out there. I know most of the cars will not see 6-7k rpm for a few minutes. However, I have seen some built cars go up in flames. Sometimes you do have to weight the pros & the cons of an upgrade/modification. Just food for thought, no need for tin hat.
