turbo blanket

[Smiling lemon]

Since i have the time now I'll elaborate. So easy turbo blankets and headed wraps increase performance is two part.
1st: keep heat within the pipe before turbo i.e. more heat more pressure. More pressure on the turbine allows higher compressor speed increasing available boost.
2nd: insulating the turbine from the compressor reducing intake charge temperatures. Lower temperatures higher air density, Bigger bang, more power. And you can increase this effect further by using ice on a liquid intercooler or N2o on a air intercooler

Pros more power
Con higher temperatures in your turbo.

Long upgrades it becomes irrelevant do to the heat soak. Because of the higher temperatures you also cook the bearings and any oil in the turbo is going to be fried. Variable geometry turbo components also do not hold up to high temperature
