Anything from COOL-IT, is good stuff. I have rolls and rolls of thier header/exhaust wrap which can be used on absolutly everything. Works great.
Keep in mind that the turbo wrap isnt really for performance gains... its more of a safty thing... to prevent anyhting that may end up flapping around near the 1200 degree turbine housing from catching fire.
i could def use some of that stuff

I am using it. I would recomend it. It helps keep under hood temps down. It also
keeps heat in the turbo longer. For performance it is good, more heat stored in the turbo, means more energy. The turbo will not be as laggy. will you feel it in the seat of your pants?, maybe not, maybe. The more heat left in the turbo, between shift pionts for example, will result in less time to heat the turbo back up for it to produce boost.
Mainly this just means a more responsive system.
You will definatly want to have a turbo timer to alow for plenty of cool down time.
Yeah i espceially need it to keep the temps down under the hood. I noticed today after driving for awhile in the rain, the hood was smoking right above where the turbo sits. (2200 engine)
