I've always had it wrapped. The heat without some kind of wrapping or shield is unbearable.

im wrapping mine as we speak, have the wrap soaking and the downpipe on my bench.

Cant wait to see some before and afters on this one

I don't think you're supposed to soak the wrap, just moisten it a little bit. Or at least that's what I thought and have done in the past.

do those universal turbo blankets fit on the stock turbo?


Does anyone have the stock turbo/manifold heat shields for s5?

instructions say to allow to soak for a few minutes at least the DEI wrap I was using said that.
I was told by others to soak it as well- allows for a tighter wrap

ya i soaked mine. too bad i didnt take pics. but the blanket i did notice made adiffernce according to my intake temp sensor on haltech.

I bought the Ebay one posted earlier in Grey. It looks great and is really good qaulity(was around 115.00 so hopefully the price stands for quality). Fits my 62-1 very nice. We will see how it performs once I get the car running.

Speaking of heat shields and wrap; I've heard that over time, heat wrap makes holes in exhaust components. This hasn't happened to me, but I wonder if it's happened to anyone else. As far as heat shielding goes, I know of a person who chose not to heat shield his turbo because it would make it somewhat of an oven, so it's better to have it open so the heat can escape better. Anyone know if any of this is true?

my car is not a daily, its pleasure driven.

if not getting roasted in the car is a by-product of some of the exaust not lasting as long- so be it!

chances are the motor will be swapped before the exaust anyhow, lol

Actually heat is good for a turbo. A turbo is spooled not solely by the velocity of the exhaust but also by its heat.

Heat shielding = win/win

Thanks for the info!

ive heard the best wrap you can get is old fire hose material if you can find it. its usually hard to get and often requires you to know someone who is a firefighter. but is suposed to be like 5 times better then the normal wrap.

sounds plausible....now who's a fire fighter?

bump for more info on that cause i have a friend that works for afd .

Two or three layers of regular parts store heat wrap works amazingly well. On my previous turbo setup I had about 3 layers on the turbine housing and could lay my hand on it while the engine is running and hold it there for about 6 seconds. Consider how much of a reduction in heat that must have been from the raw turbine housing. Far better then any ceramic coating...

Both if you can but a turbo blanket will make a significant difference in engine bay temps which equals heat exchangers being able to work a bit better.

it just so happens that I can get this stuff. What do you suggest to wrap the turbo and downpipe with it? Just wrap it around very tightly and then safety wire?

I cant imagine trying to wrap a old fire hose around a downpipe or turbo?

I cant imagine being able to cut it to so easily into 2" stripe to try to wrap it that way, or being able to slit it down the middle and have it make bends too easily?
whats the diamater of a old fire hose anyhow?

I can see some bloody fingers and other injuries from trying to slit open one of those hoses, lol

solareon

that's why you wear gloves when cutting stuff. They have to cut the stuff somehow to make different length hoses so it must be cuttable.

just about to search for this. i have a single layer on my DP and it gets REAL hot in the car....i also have a gotham racing heat blanket.

So you actually managed to wrap the turbine housing as well with downpipe wrap? and pictures of this or tips? I would imagine it would be hard to wrap there.

Rob XX 7

iTrader: (8)

making a cut to length is much easier- im sure they have nice band saws for this, or they use hacksaws, try slitting a hose down the middle though to make it a split hose- not so easy.
Now try cutting it to mimic heat wrap which comes in 2" strips- cant use a cut off wheel as im sure the hose will melt as you try to cut it, similiar to cutting rubber with a cut off wheel- if you have ever tried it aint easy.
Maybe with a scroll saw, but that aint gonna be easy either.

I would like to hear one person who actually cut old fire hose and made it work because so far it sounds like one of those things people repeat but have never seen work.

btw- I double wrapped my entire DP, I only drove the car about 10 miles so I cant say how different it is- but so far the shifter feels MUCH cooler.
I am going to take off the exaust and wrap the mid pipe that goes from the DP-pre silencer- im expecting that to make a huge difference in cabin temps

azfc3s

you could coat the downpipe, exhaust manifold, and/or turbine housing with ceramic or something like what jet-hot offers.

It was a real pain in the ***. Keep in mind this was the stock turbo. I just crossed the wrap under and over it until complete coverage was achieved. Whether it would have held up for the long term I can't say. If I was going to do it again and it needed to be reliable for years, I would make a metal heat shield to fit the stock turbine housing then rivet several layers of heat wrap on the bottom and top.

The Griffin

If you are running a "dry" cartrage turbo (i.e. oil only) I would be hesitant about using a blanket,but that's just me. A shield with insulating material riveted to the underside would make a decent shield as Aaron Cake mentioned ,probably the next best thing to the blanket and definitely outlast it also.
