Turbo blanket to reduce engine bay heat

[Uwon]

^^^pretty compelling video that the blanket does keep the engine compartment cooler but it really makes little difference performance wise on the 6.7 L Cummings diesel with a turbo that has a 6”+ separation between the exhaust and air intake sides.
I wonder if a similar test has been done on air cooled and water cooled turbo Porsches with their unique rear located boxer engines.

I think people are forgetting the 944 is not the usual turbo car.

a) the turbo is quite far away from the exhaust ports so heat loss is higher than normal
b) the turbo is right underneath the intake manifold.

I think there is defiantly a case for improved performance due to retaining more heat in the turbo to improve spool while keeping the intake temps down post intercooler. Turbo blankets are common in marine applications where the turbo is mounted further away from the exhaust manifold due to packaging restraints.

Im not overly concerned about oil contamination, the blanket only covers the turbine housing, not the core.

I think im going to buy a Funk motorsports turbo blanket for the hot side of my turbo as well as a wrap for the manifold. Ill give some feedback here.

Hoping to see a spool up performance increase and significantly reduced engine bay heat.

i built a heatshield in between my turbo and intake, dont like turbo blankets in tight spaces.

Do you have a picture of your heat shield that you can share?

Here you go

Thanks, I did the same thing with my intake manifold and the brake booster shield.

Why would you even consider a turbo blanket that keeps the heat in, heats up the oil lines unnecessarily, burns up oil into coke (sp?), shortens the life of the turbo bearings in order to keep the rest of the engine compartment "cooler"? Oh, yes, it goes out the exhaust...and there goes another prematurely burned up catalytic converter worth thousands, pre-muffler, etc. And the claim of more power...I say humbug. Alternative facts....had enough of that recently.
