Turbine housing shields are essential components in high-performance and motorsport applications where managing extreme heat from turbochargers is crucial for both performance and reliability.
Here’s a complete guide to help you understand their purpose, benefits, and available options:
What Are Turbine Housing Shields?
A turbine housing shield is a thermal barrier or insulation cover placed around the hot side (turbine housing) of a turbocharger. It can be:
A blanket-style shield (flexible, removable)
A rigid heat shield (metal casing)
A ceramic-coated or composite shell
Materials Used
Basalt or Silica Fabric: High-temp insulation for flexible turbo blankets
Titanium Weave: Excellent heat resistance and durability
Stainless Steel Mesh: Often used in rigid shells for external protection
Ceramic Coatings: Applied directly to the turbo housing for durable heat control
Popular Applications
Track-day and endurance race cars
Drift and drag racing vehicles
Rally cars with long periods of high-load driving
Street cars with high-performance turbos
Pro Tip:
For extreme motorsport use, pair a turbine shield with:
Heat wrap on downpipes
Gold foil reflective barriers on intake side
High-temp thermal sleeves for critical hoses and wiring
