Turbo Heat Wrap

[Mayolives]

Boost Logic and others, manufacture a blanket that wraps around the turbo that significantly reduces under hood temps. My buddy has one on a Neon track car and it does work. You can actually put your hand on the wrapped turbo after being on track. I'm reluctant to install one on my GT35r equipped, race car due to the possibility of damaging the turbo. I emailed Garrett for their take on the subject, but they choose not to respond. Does anyone have experience with this product or have an opinion about it's use? By the way, the hot part of my system have been Jet-Hot coated.

You aren't going to damage the turbo. They glow red under load. I had to wrap the turbo on my truck as it was really close to the plastic valve cover, brake master and plastic dashpot. It saw more load/heat than most turbo cars because of the weight if the truck and big a$$ tires. I never had a problem . I was on boost from every stop light and would often be under boost seconds before parking it and letting the turbo bake .

Another theory (mine) may be that by having the insulating blanket around the turbine housing, you are avoiding some damage that could occur from rapid heating/cooling cycles by keeping the turbo at a more constant temperature. Just my $.02... On diesels at least (the majority of my experience) the water cooled turbine housings were most often reserved for high horsepower applications, due to the higher exhaust temperatures damaging the dry housings. In my opinion, theres no downside to having an insulating blanket on the turbine housing and even the down pipe.
