Turbo Blankets: Where Heat Meets Performance
If you’re serious about turbocharging, you’ve likely come across turbo blankets. But where did they come from, and why are they now a must-have for performance builds? Let’s explore the origins of the turbo blanket, the importance of size-specific fitments like T3, T4, and T6, and highlight some top options from Black Sheep Industries in Canada.
🔥 Origins of the Turbo Blanket
Turbo blankets, also called turbo heat shields, were born out of necessity. In the early days of turbocharging—particularly in motorsport—engineers realized that turbochargers were becoming massive heat sinks under the hood. This heat not only raised intake temperatures, reducing performance, but also jeopardized nearby components like wiring, hoses, and even brake master cylinders.
Initially, racers improvised with exhaust wraps and metal shields. But as turbocharger technology advanced, so did the need for a more effective solution. Enter: the turbo blanket.
Made from high-temp insulating materials like silica fabric, ceramic wool, and stainless steel mesh, the modern turbo blanket wraps around the turbine housing and keeps heat where it belongs—inside the turbo.
🚗 Why Size Matters: T3, T4, and T6 Applications
Turbo blanket sizing isn’t one-size-fits-all. Your turbo’s frame size—T3, T4, or T6—dictates which blanket you need:
-
T3 Turbo Blankets
Ideal for smaller, responsive setups. These are commonly used on four-cylinder applications or street builds that prioritize fast spool-up and compact packaging. -
T4 Turbo Blankets
One of the most common sizes in aftermarket performance. Found on mid-to-large power builds, T4 turbos benefit heavily from proper thermal insulation in both street and race environments. -
T6 Turbo Blankets
Built for serious power. These large-frame turbos are common in drag racing, high-horsepower street cars, and diesel performance builds. A T6 blanket helps manage the massive heat these units generate.
🇨🇦 Canadian Innovation: Turbo Blankets by Black Sheep Industries
Black Sheep Industries offers high-performance turbo blankets designed and tested for Canadian conditions. Their product line includes:
-
T3 Turbo Blankets
Great fitment for compact turbos with tight engine bays. -
T4 Turbo Blankets
A versatile option that suits most aftermarket builds. -
T6 Turbo Blankets

These blankets are crafted with durability in mind, using premium insulating materials to reduce engine bay temperatures, improve turbo response, and protect nearby components from heat soak.
🧰 The Real-World Benefits
-
Lower under-hood temps = safer, more reliable performance
-
Faster spool-up = more responsive throttle
-
Better thermal efficiency = improved exhaust energy retention
-
Protect nearby parts = avoid melted hoses and wires
Whether you're chasing quarter-mile times or just want a cleaner, cooler, and more efficient turbo setup, a turbo blanket is one of the smartest upgrades you can make.
