Turbo blanket

Noiseydiesel · May 21, 2022

Okay, playing with the reassembly of the project once more and looking at the turbo as I got the down pipe mounted to the turbo.
Oh joy. pulled off the hood latch and laid a length of plywood across the opening, (no radiator) stretched out across that and a prayer sent up. I believe I got lucky and got the down pipe on the turbo.

So looking at this "coal stove" on top of the engine, pro's and con's of getting a turbo blanket to stuff around the turbo?

Thanks in advance!

It keeps the heat within it. I'm not sure it's super important on a truck due to how big the engine compartment is, but I did add one on my E350 because it's buried in the back of the engine bay right by the doghouse cover.

It's still a good idea on a truck. It will help to keep the heat away from the return lines, cables, wiring, etc that runs close to the turbo. It helps to keep the heat away from the firewall. Even if there is still insulation on the firewall, it will help to keep heat out of the cab. It will also help the turbo to perform a little bit better. It will spool up slightly faster and build boost slightly sooner. That may not be a big gain, but for the cost of the turbo blanket, it's a cheap gain. I feel that any insulation that you can put over, under, or around your turbo is well worth the cost and effort.

+1 to the above, they work great and keep damaging heat out of the engine bay and cab. 700*-1200* will mess stuff up fast.

It definitely helps a little with boost and spool and efficiency, too. And I'd guess the bigger the exhaust housing the more benefit you'd see from a blanket, since there's more surface area to bleed heat.

Just because it's crazy to me, I pulled over one day to poke around the turbo without letting it cool and realized I touched the turbo blanket accidentally and it didn't even feel warm. What should have been about 400* was ambient to the touch!

I haven't noticed any delay in mine on spool time. Cooler temps on surrounding components sound like a winner.
Next question is, any particular recommendations? Fleabay has a few around $30/35 That I could probably make work unless there is a particular one that is recommended.

I put a cheapy one from eBay.

It likely only makes a small difference. On the other hand, you may be able to notice the difference after you install the blanket. You may not be able to tell it if you're experiencing lag.

That look pretty close to the one that I bought. I feel that even if it's not the "best" quality, it's still better than nothing.

I got it ordered up. The turbo is about as warm as the wife is getting to me not having this done.

any of these cheaper blankets caught fire? I read a lot of reivews on amazon of ppl burning them up and that terrifies me but wondering if our engine bays don't get as hot due to size?

No issues here, I got some cheap T3 Titanium job on amazon. Cheap turbo blanket it's unavailable now. But I drive it up to 1150* EGT's, sometimes 1200* and never had any problems.

I used a snap on style exhaust pipe wrap that came with a Rear Air Suspension Kit we put on a buddy's new Dodge 5500. He shortened the tail pipe to dump in front of the axle, and didn't need it to protect the air springs. I was concerned about frying the plastic injector caps and fuel return lines that are right under the turbo, since there isn't much air flow back there. Just used some steel wire and wired it into place. Picture was during mock-up, so no wires yet.

Chevy starter blanket

Noiseydiesel · Mar 28, 2023

I like the starter blanket idea. That turbo stuffed in the rear and the down pipe near the firewall also is in need of something. I found that out when pulling back the carpeting to get the trans tunnel cover off.

some of you are brave running NA injector return style under the turbo

I bought a cheap titanium blanket off Amazon for a t3/t4 turbo slapped it on to keep engine heat out of the engine bay
Does fine
