Then why didn't you vote? ^^^ It always seems the vendors that offer coating and wrapping always have studies and huge things about heat soaking. But they never really have any solid proof it helps that much. Other then when it causes headers or ups or such to crack from the heat.

If it comes coated more power to you. If you have to send it in to have done waste of time and money.

I am going to wrap my UP when I install. It's hot enough in the engine compartment as is and I have seen the flanges on my stock UP glowing red a few times! Thats gotta leave a mark if it isn't insulated.

 

Performance wise, it may not be measurable. For long term reliability of other components under the hood, IMO, it's necessary.

I wouldn't wrap it, the steel will rot real fast.

 

My headers were on for about 6 months (winter only) and they melted my plastic undertray because they were not coated. I don't know how bad it would have been in the summer.

 

It gets real hot under the hood, and anything you can do to keep heat in is a good thing.

important as in in what? keeping as much heat out of engine compartment as possible which in turn should help lower interior/under hood temps or the performance gains by higher gas flows or maybe the safety factor of not getting burned if you happen to touch a pipe? i have up/dp/turbo wrapped and all i will say is run the car hard then stop open hood and put you hand on/near wrapped pipes. :icon_cool < get it? bosco

I can rest my hand on top of my turbo blanket even after running hard, spend your $ there not on a coated pipe

 

thats what i was getting at when i said put your hand on/near the pipe. wrap all the pipes. bosco

Is a turbo blanket good for long term reliablility, will stuff corrode faster?

 

I am kinda interested now.

I talked to one blanket vendor and my thought was that the turbo blanket might be good for temps underhood and to prevent heatsoak, the cost is all the heat trapped in the turbo and perhaps a shorter turbo life. The vendor (I can't remember who) said that he thought a blanket would shorten turbo life 10-20%. I asked what the stock turbo life was for the LGT and his reply was about 60k miles b4 the cast housing started to crack and lose performance. I don't know how substantial a crack has to be to "lose performance" but I imagine it would have to be all the way through the housing. However, I truly doubt Subaru would install a turbo that failed in this way at 60k miles. It wouldn't do much for their reputation given the cost of replacement.

it's fiberglass webbing. most new exhaust system pipes are SS not to worry. the blanket is not on turbo that tight not like a wrap, anyway your naked turbo is going to oxidize/rust with a blanket or not. you only wrap the exhaust side i don't see where that is a big issue with reliability. bearings are oil/water cooled, if someday it fails i'll buy the bigger turbo i want anyway. :icon_bigg i am/have run wrapped exhausts never had a problem. your car isn't submerged in water plus the heat from exhaust dry's it. they also have a high temp paint for sealing the wrap. i really could care less who uses or does'nt use the wrap/blanket i think it works. everyone has their own ideas and experiences i guess it's what works for you. bosco

I can put my hand on the trunk after driving the car and it is not hot to the touch; should I install a trunk over the downpipe??? :lol: What about the floor mat?

 

If you want to wrap your exhaust system, put a sweater on it or knit a tea cozy for it, go for it.

We wrapped your sprinkler system :lol::lol::lol:

Just seems like our engine bays are on fire when you open the hood (ok, not literally). Even the hood prop rod is hot to the touch. If I did it again, I'd get everything coated--turbo, UP, DP, maybe headers. I just don't want to take it all off.

 

I tried to wrap my turbo (thermotec) but it's kind of cumbersome. The wrap does indeed get hot, so you don't want a bunch of bulk near components you want to keep cool (and you don't want the wrap touching other things...if that makes sense; hence why the stock heat shield has space between it an the turbo.)

 

I wrapped the upper 2 ft or so of my DP with thermotec (and used their high temp paint). I'm sure wrap works, but coating just seems a heck of a lot cleaner and more complete. Also, my car stinks a bit still even after several weeks due to the wrap and or paint. Thermotec says it's the curing process.

 

Last, if you try and to wrap with the pipes on the car (what I did) it's a lot harder and would suggest wearing safety glasses and gloves--glass fibers were floating everywhere.
