Here's the theory
The turbo is really hot. (obviously) When you have a hot turbo in a cramped engine bay you end up with a hot engine bay. When the engine bay gets hot your IATs rise and you lose power. Also since the engine bay is now hot it is harder to get rid of the extra heat from the engine. When you use a turbo blanket it will keep the heat inside the exhaust system instead of releasing it into the engine bay. This improves turbo response since hot gasses have more volume, and the gas volume going through the turbo is what spins it. In our cars it probably isn't that significant since our turbo is bolted to the head. The lower engine bay temps will help though when you are sitting in staging at the drag strip or at autox.
I have half my downpipe wrapped and it made a noticeable difference. This winter I would like to finish wrapping it and get a turbo blanket. For those concerned about fire hazards, exhaust wraps and turbo blankets are not knitted from yarn by factories of grandmas trying to keep those turbos toasty warm. They are made from fiberglass. Glass melts at around 2600 degrees. If your EGTs are that high then you need to contact your tuner immediately.
Is there any real data that shows a blanket actual works? People can speculate all day long on this and without any real data, then that's all there is, theories.
It's also worth noting that various OEM's are starting to equip their cars with turbo blankets from the factoryIs there any real data that shows a blanket actual works? People can speculate all day long on this and without any real data, then that's all there is, theories.
Also, how did you notice a difference with your DP and in what way?
