I'm curious if any of you have any experience or information on turbo and exhaust manifold blankets. Are they worth it, any pros or cons to using them?
Depends on the turbo setup. Underhood temps will be night and day difference. Intake charge temps go down 25+ degrees. Initial spool isn't always noticeable but mid-range spool (think passing gear) is. It'll make max boost more quickly and typically see 1-3psi overall boost increase on most setups.
I just put blankets on both turbos and my manifold. They look and fit great! I can tell my EGT's are definately lower, but I'll have to drive more to tell you just how much lower. Levi does make a great product and back's up everything he sells.
