Hey I am considering put in a heat shiled but I am not sure which one is better the main reason is prevent my ABS line from frieding and keeping underhood temps down, I really don't want to put a blanket I prefered the stainless steel cover because using a blanket after shutting the car down it will keep the heat inside.

you can always install a heat reflecting sleeve on the abs sensor harness.

 

If you are only concerned about one component, then shielding that component may be the way to go. To keep overall under-hood temperatures down, the turbo blanked is very effective plus it apparently reduces spool time. Some believe that the turbo blanket traps too much heat coking the oil causing bearing damage. I have not been able to find a good thread that really drills into the pro's and cons of the turbo blanket and either confirms or denies if turbo blankets will actually ruin the bearings.

 

stainless steel cover anyday.

 

Never thought about keeping the heat on the but I think ill be getting me a cover instead.

 

I ended up using a turbo heat blanket along with a lower intake manifold heat blanket, ceramic coating my upper and lower intake manifolds, and exhaust wrapping my downpipe and exhaust manifold. Seems to keep the heat in check as much as possible. Still gets pretty hot though.

 

The heat blanket is almost a one time deal. As the heat destroys parts of it.
After removing the turbo once or twice, my blanket started falling apart.
Then went to a SS heat shield, it does not fail with use.

The blankets also cost more besides their shorter life.

 

That's exactly what happened to mine. ^

Mine burned on the dyno.. Didnt even have to pull the turbo once out of the car

 

If you don't buy the cheap turbo blankets you can reuse them for years to come. The bigger the A/R turbine housing you have the more benefit you'll get from a blanket. Eric's cooking pot method is the cheapest one out there if you don't mind fabbing for an afternoon

 

DEI makes a very high quality 'titanium' blanket.

 

My buddy's DEI Titanium lasted about 1 month on the 20b. He sees EGTs peaking around 1600f.

 

Stainless steel shield works fine in my FD

 

Thanks for the input everyone, I think almost every component under my hood (engine wise parts) is coated in hi-temp but temps is still high. I end up buying the following stainless heat sheild from Amazon company name godspeed yeah I know they r cheap,. But the material they use for the stainless steel is good. I put it to test and accroding to my digital meter downpipe ( no cover) read 500 degree/ on top of the stainless steel cover read 150 degree, that from cold engine startup and let it run for 15 minute water temp read 177 degree when i shut it off to do the test.

 

Mine was from the now defunct Gotham Racing and cost over $400.

 

Odd, I saw peak EGTs consistently higher than that and my DEI blanket lasted over 2 years, when I took it off it was still useable by a friend that I gave it to.

 

Could be Q/C, we called and DEI sent a new one to us just haven't been using it since. I should mention that as unbelievable as it is the 20b just creates so much more radiant heat than the 13b it is unbearable. I always thought that things surviving in an FD engine bay was a miracle but with the 20b my thinking was altered.

 

Well I finally got installed here are few shots of the heat sheild.

 

Do you like the Jet-Hot Coatings ??

 

^in my experience they do not last on rotary exhaust components.

 

With fresh paint in the engine bay I do not want anything damaging the paint. I chose a turbo blanket made by PTP. They are around $150 for the T6 version. I'll let you know how it holds up after some high heat passes.

Stainless heat shield.

Less chance of saturation and easier to put out with fire from oil or coolant.

 

I was going to have one made out of thin stainless, then put a inconel sheet material in it as well. Has anyone put a meter on the stainless shield? Thing has to get really hot?

 

Stainless is the way to go

 

The custom inconel type is the best, but they are very expensive and I've heard that they may rattle a lot.
