Racing Turbocharger Heat Shields & Blankets

It is no secret that a turbocharger heats up to extreme temperatures during operation. Its hottest component, the turbine, works at a temperature ranging from 900 to 1500 °F approximately, just like the exhaust manifold, which makes these two parts the main generators of heat in a vehicle. But what's normal for the turbine and manifold is not that good for the air intake and various mechanisms and electrical parts under the hood. It's well-known that cool air intake is good, and there are different accessories meant to make the incoming air as cool as possible.

Turbo blankets are some of them. Made of heat-resistant fiberglass materials, they are put on the turbine and help to keep its heat inside preventing it from spreading into the engine bay. Most producers of these accessories promise improved turbocharger performance, and some racers even conduct certain experiments to prove (or deny) such statements using a thermal imaging camera, temperature sensors, and other specific equipment. According to one of such tests, the temperature on the surface of the installed blanket was about 2.5 times lower than that of the uncovered turbine housing. The temperature of the compressor and oil and coolant lines of the turbocharger was also notably reduced, so the blanket's role is quite obvious.

As for heat shields, their use also makes sense if you want to protect neighboring components from the heat emitted by the exhaust system. In practice, not every driver is able to notice the difference in performance with or without a blanket, but it doesn't mean that these changes also remain unnoticed by the timers measuring a lap time on the racing track. Making minor or more serious improvements here and there and applying them reasonably, you will finally attain perfect performance. Our online store is always ready to help you with that by supplying first-class products including turbocharger heat shields and blankets.
