Which turbo blanket lasts the longest?
Which are you guys using?

 

I've been through a few blankets now, and without a doubt this bad boy wins the prize:

Thanks!

 

"This shield is not designed to be removed after it has been through heat cycles. After the fibers have been heated they lose their initial flexibility. This does not reduce the thermal properties of the shield. Be aware of this before you decide to remove the shield."


So if you want to swap turbos, you have to buy a new heat shield also?
Or does it just get stiff and tough to remove, but still re-usable?

 

It probably gets brittle and loses the flexability that it had compared to when it was new.So if you do take it off you would have to do so with the utmost care as to not break it.

 

id say this is more of a concern than having a maracas for a shield..

However, if any flammable fluids are introduced to it, conditions may be suitable for a flame to be produced.

coated with a typical blanket imho is the model solution to reducing temps.. shielding the lim is also ideal

 

Is it good to have a blanket? I thought it cooks the bearings

 

ive heard that as a rumor or anecdotes, but i would like to read some hard evidence or info from turbo manufacturers regarding that. would all these companies manufacture turbo blankets if they were really killing the turbos? doubtful

all i know is turbo blankets (good ones) work INCREDIBLY at reducing engine bay heat.
for example, i was over at a local shop recently and they were dynoing a 1100hp TT mod mustang.... he did 3 full pulls, coasted to a stop, idled a min or two and shut the car down.... and told me to touch the turbo blanket... warm, but you could grab the thing easily. pretty amazing, considering maybe 1/4" on the other side of that blanket was an insanely hot turbo.

 

BTW, forum vendor turblown makes some REALLY nice shields and blankets

http://www.turblown.net/store/index.php?categoryID=18

in their description of their turbo shield, they say the following :

"Generally turbine blankets were designed for diesel applications because of their lower exhaust gas temperatures. A blanket on a turbocharged gasoline setup will simply create an extreme heat soak environment and turbocharger bearings consequently suffer. "
