Lookin on ebay at a subaru, and noticed this thing on the turbo


Anyone know what it is and why? is it a "hood" to keep all the heat into the turbo, and off the rest of the engine bay? If so, seems like a great idea...

in tight engine bays with rubber lines and fuel lines running close it to the turbo, just provides a little protection. also helps to retain the temperature on the exhaust side of the turbo to try and reduce turbo lag. Haven't seen proof of this thou.

Yeh they are turbo bags. XTR also make them. My brother had a few issues with these on his Drag Car. I don't think these are suited to high high high horsepower cars. It ended up cooking the bag. Smoke pouring out of the engine bay. That said, a few mates run them on the VL turbos and haven't had any issues. They help keep heat away from other things such as ABS units, sensors etc etc. They don't help with turbo lag.

its like a heat shield on ur exhaust manifold,worx the same way.jus keeps the majority of the heat in 1 area.
yes there mostly artermarket.

MTQ sell them, they are SONIC branded. They are good and bad, they do retain heat, reduce lag and lower underbonnet temps, they also can cause the exhaust housing to fatigue due to the retained heat.

We use these at work and also have them made to cover the whole exhaust for safety perposes on Cummins M11's.

funny i see that pic... i was once told by them garrett boys, that you void turbo warranty if these sleeves were used... but by looking at the pic, they obviously make and sell them.
