Full Race WG Blanket For TiAL MV-R 44MM & MV-S 38MM Wastegates

Full Race Wastegate Blanket Fits TiAL MV-S 38mm/Garrett 40 /Turbosmart 40 or Tial MV-R 44MM/Turbosmart 45MM 

Wastegate diaphragms are exposed to some of the most extreme and localized heat found in your engine bay, plus constantly heat cycling – This is the number one reason for wastegate failure, boost leaks from the wastegate, and inconsistent wastegate operation.  Full-Race WG Blankets are designed to withstand the harshest of conditions and extend the life of TiAL MV-R and MV-S wastegate diaphragms, as well as protect nearby components from damaging heat.

Our new WG Blankets are constructed with an outer layer made from basalt volcanic rock (Rated 1800°F Direct Heat / 2500°F Radiant Heat) formed into fabric and woven into a tight mesh weave using Kevlar thread. Full-Race WG blankets are internally insulated with high temperature calcium magnesium silicate wool (Rated 1832°F Continuous / 2300°F Peak) overlaid with a high temperature stainless steel mesh for increased durability, improved thermal resistance and proper fitment.


Full Race WG Blankets for TiAL MV-R and MV-S Wastegates

Full-Race's WG Blankets minimize heat transfer to the wastegate diaphragm, resulting in increased boost control consistency and optimized performance of externally wastegated turbocharger setups.

  • TiAL MV-R 44MM
  • TiAL MV-S 38MM 

*Can also be used as a universal WG blanket / heat shield for other similarly sized wastegates (TurboSmart and PTE External Wastegates with dimensions of 100mm x 106mm)

What's Included?

  • Full Race WG Blanket For TiAL MV-R / MV-S Wastegate
  • Stainless Steel Spring and Stainless Steel Wire to provide a perfect fit

What does volcanic rock have to do with wastegates?

90% of the world’s volcanic rock is made up of basalt – this unique material can be extruded and melted into filaments and woven like a traditional cloth fabric.  Soft to the touch, this one of the toughest and most heat resistant materials available.


  • Wastegate shields are not designed to be removed after the first heat cycle. The fibers lose their initial flexibility after they are exposed to the extreme heat of a turbo housing. This does not reduce the thermal properties of the shield.
  • If you are installing the WG Blanket using the included safety wire, be sure to bend over a small "pig tail" to avoid being cut by the sharp end of the wire protruding out into the engine bay. Twist safety wire approximately 7-10 twists per inch using pliers or twist by hand. Over twisting will cause the wire to snap. See example:
