Turbo Blankets?

[Merica]

Hey from someone who used to be in the WRX STI world, why are turbo blankets never talked about with these motors? Prevalent in diesels as well. Haven't seen any and was curious.

They do very little, if anything at all.

I believe they are shown to make a large difference during spool up.
Much more boost and resulting torque at tip in.

Also no talk of a turbo timer.

Also no talk of a turbo timer.

No need for a turbo timer with modern oil & water cooled turbos. Regarding turbo blankets, have you seen what the do to turbos on daily driven street applications? Trapping the heat can cause cracking and corrosion on a daily driver. In a race application the certainly have merit but for the street there really is any benefit.
