DieselSite GTP38 TP38 Garrett 38R Wicked Turbo Blanket - 7.3L Ford Powerstroke

Turbo Blanket material is made with Lava Rock fiber which can be an irritant to some people by touch similar to fiberglass installation. If you have sensitive skin, please consider wearing gloves during your install.

Why a Turbo Blanket?

Turbocharger insulating has been promoted for years for their benefits.

1. Insulating the exhaust side of the Turbo can Increase Power AND Decrease Turbo Lag.
2. It decreases under-hood temperatures.
   • Keeping the "under the hood" temps down is all around a good idea. Primarily allows the intake charge to stay cooler. Inter-cooler and radiator works more efficiently.
   • Less wear and tear from temperatures on plastics and rubbers.
   • Less heat transfer to the firewall and cab.
3. Keeping the turbo section hot will help the exhaust gases flow faster. Thus: reduction in spool times.
   • How does this help the turbo to spool faster? In physics, dissipating heat slowly equates to wasted potential energy. Thermodynamics could explain that the more heat you retain in the system, the greater the efficiency of the turbo is.
   • Trapping heat in the turbine is actually a good thing. The expansion of hot gasses will cause the turbo to spool faster.
4. It looks cool! However, the visibility of the exhaust housing in the turbo in the 7.3L is limited, so "looks cool" is at the bottom of the list.
