Turbo blankets? good, bad, or not worth it?

[supermech21]

Whats the consensus on turbo blankets? Do they work well? Any adverse affects? Does the trapped heat in the turbine housing hurt anything over time?

Heat is energy so its not bad in a turbo. I see that you have an SRT-4 so the blanket will really help protect your underhood equipment if you are running a very large turbo. If you have the stocker I wouldnt consider one though.

I usually like to run a Snuggie on my turbo

You dont know what a stock turbo/manifold looks like do you? It would be impossible for a blanket to go on.

not really ive worked on a few and its not that hard to access them

lol at snuggie.

he was making a generalized statement concerning turbo's and blankets....

any why try and argue a question YOU asked in the first place...

not impossible,but improbable, and impractical

and the ones you have linked wouldn't work anyway seeing as how you have a "unicast" design for the turbo mani/housing anyway...maybe with a bigger turbo, or you knew somebody with some exceptional stitching skills

[st00lenpeace]

Ok.... when someone answeres a question I like a detailed answer.

You said heat is energy right? How does heat help a turbo? I understand how wraping it would be benificial to other underhood components but, does it really have an effect on the turbos functionality? If so, how?

Stock:


Turbo blanket will not fit. Yes impossible, improbable, as well as impractical.

My turbo:


Turbo Blanket will fit.

I never said i had a stock turbo fold, i thought it was a "given" that im running a aftermarket turbo.

Well....considering that the first post NEVER specified that you had an upgraded turbo....

and considering that your Sig Line says:

2005 SRT-4 (stock)

it was a "given" that you were running stock
and saying:

I never said i had a stock turbo fold, i thought it was a "given" that im running a aftermarket turbo.

doesn't help your case much and if i were you, i would fix that sig line then if you want to avoid future confusion

and if you know someone, then you CAN have a blanket made for a stock srt4 turbo...if there is a will, there is a way...all it is is heat resistant fabric and stitching...

point is...be a bit more specific next time

Heat doesn't help a turbo, but it doesn't help it either...

consider this...
blankets hold heat in the housing...
since there is now more heat in the housing, there is more heat on the turbine, therefore more heat transfer to the shaft and the compressor, if you have the right cooling mods and exhaust, then this isn't going to be too much of an issue and you will never know anything different is going on...but the possibility is still there...worst case scenario:

the turbo housing (hot and cold sides) become way heat soaked, so the air that is entering the compressor is getting hot immediately, add the heat generated by compression and you have some pretty high temps, after time, it doesn't matter if your intercooler is running 90+% efficiency, it will become heat soaked resulting in higher IAT's and lower power,

but again that is just worst case, on a stock system, a turbo blanket would be plain unwise, on an upgraded system, it wouldn't matter too much as long as you kept the IAT's under control.

If you are wanting to purchase a blanket for the purpose of saving engine temps and not damaging wiring or other devices that may be damaged because of heat, these are an "ok" idea. If you are doing it to improve performance, there isn't any performance gains. There also harder (shorten the life) on the turbo because the "turbo blanket doesn't allow the heat to escape.

If you want to shield something, put a turbo shield on would be easier solution.

My bad, i didnt take into account my sig...

[Johnny wangwang]

I could think of a few reasons to use a "blanket"

-quicker spool up from the hotter air going into the turbo and the not escaping through the turbine housing. These are turbos. They are made to get hot. The shaft is cooled so I doubt that compressor wheel would get that much hotter.

-lesser under hood temps. This would probably negate the fact that the turbos getting a lil bit hotter.

-cleaner look then that rusty turbine housing.

Depends on how the shaft is cooled, if it's oil cooled then good luck or buy an oil cooler, and if it's water/oil cooled then it's going be be harder for the compressor to heat up..

and hell...if you can afford it, skip the blanket and go with a ceramic or high temp powder coat....hell you can get them in damn near any color you want now...

[st00lenpeace]

I think im going to go with the general idea that heat has no performace advantage... Maybe through some principal matter of thermal kinetics, heat would cause a slightly faster spool up but, I dont understand how the hell thats really possiable or, if its really worth all of the other negatives.....

so therefore, I'm not going to speculate other then to say "Heat=bad"...... Turbo wraps/blankets are a bad idea in my opinion.... I'd agree with Rich in saying that if you want to sheild something from the heat of the turbo, then do so but, traping the heat on the unit itslef just does not seem like a smart idea at all.... especially considering that realiability is just as important as the power you seek on a street driven build

[breathinezinbri]

To my understanding you want to keep the heat retained inside the trubo for spool up. The hotter the air the faster the air will move or escape. This is one of the benifits from coated headers. The scavenging effects of removing the exhaust gases at a faster pace. The other of course would be to keep underhood temperatures down. On my wrx since I have a tmic it helps keep my ic from getting heat soaked. And I do have the benifit of oil/water cooled turbo. This is the first I have actually heard people not wanting a blanket becuae it wouldn't affect performance and damage the turbo. I just don't agree...my 2 cents.
