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.
