Recently noticed some nice examples of wrapped exhaust, and was wondering if a turbo blanket would be appropriate for a stock turbo...

Thoughts on turbo blankets?

thanks,
manny

Not worth the bother and higher egt.

Sounds counterproductive. Why would you want the turbocharger to get even hotter? Now a water-cooled turbo from an old Volvo....

Wrapping a turbine with an insulating blanket decreases the amount of heat energy radiating from it, forcing more heat energy to pass through the turbine. Hot exhaust is expansive, and directing more heat through a turbine wheel will cause it to spin faster, increasing spool and engine power.

Basically the more heat the more energy. If that stays in the turbine housing and exhaust manifold with an exhaust wrap, the more energy you will have available to spin the turbocharger.

But the fine line is higher EGTs is not what your after, but keeping heat in is what you want. The other drawback is the possibility in keeping heat in is reduced turbo life and possible warping of exhaust manifold and turbo housing.
