Tmax-Turbo Blanket

Stay cool when it gets hot


icon  The stage & the players

Turbochargers in cars are used to get more horsepower and better fuel efficiency. Their main drawback, however, is the heat they generate in the engine bay, especially if they reach their limits and operate under extreme conditions like those in the tuning and car race/motorsport world. Undesired side effects could be a drop in power, failure of heat-sensitive components such as plastic and rubber hoses, electrical wiring, electronic components, … and damage to the paint.

Tmax-Turbo Blanket helps. It reliably insulates the turbine, keeping the hot side of the turbo hot and the cool side cool. As a result, the turbine, compressor, intercooler, and radiator can work more efficiently, increasing power and torque output and decreasing turbo lag. Preventing heat escaping from the turbine dramatically reduces the engine bay temperature which in turn means a longer life for heat-sensitive components and materials.

Glass fiber fabric with PTFE* (Teflon) coating
icon Thanks to its impermeability, it prevents the hot surface of the turbine from getting into contact with ignitable fluids like oil or fuel, reducing/avoiding thermal risk. It also helps to protect and ensure durability and increases the lifetime of the insulating inner layer, since it has good thermal resistance, high flexibility and high wear resistance. 

* PTFE, commonly known as Teflon, is a synthetic polymer consisting of two simple elements: carbon and fluorine. Due to its properties – it is highly flexible, chemical-resistant, thermal-resistant, non-stick and electrically resistant – it is used in a wide range of applications.


Mesh Foil
icon This is an ultra-thin, stainless steel fabric combined with glass and silicate fiber fabrics. Its abrasion and temperature resistance (depending on the applied glass and silicate fiber material) makes the blanket extremely stable and long-lasting.


Mesh Foil
icon The stainless-steel fabric is vibration- and galling-resistant. Applied on the sides of the blanket, it increases its lifetime. 


Silicate fiber needle mat
icon Thanks to its low thermal conductivity, it keeps the heat in the turbine housing, providing maximum insulating efficiency. High vibration and temperature resistance (depending on the applied silicate fiber material (SNM750/SNM1000) ensures longer durability.

Long-term heat resistance: 1292 °F (700 °C)

For each turbo, the right outfit

To choose the right blanket size, measure the circumference (flange not included) and the width of your turbine at its widest point (flange not included) as shown below.

 Or four good reasons why you should use a Tmax-Turbo Blanket:

icon  1° TRACK: “Let there be rock”

icon You get MORE POWER and a BETTER PERFORMANCE since a turbo blanket decreases spool-up time, increases power and torque output and reduces turbo lag.
The Tmax-Turbo Blanket keeps the heat in the turbine section of the turbo. This has two positive effects on the functioning of the turbocharger. One the one hand, it improves the efficiency of the turbine. In fact, heat is energy and hot gas expands faster, creating more pressure on the turbine wheel which spins up more rapidly. This equates to a quicker spool-up of the turbo, improving turbine performance, and subsequently compressor performance, i.e. an increase in overall boost pressure and decrease in the time it takes to build that pressure. 

On the other hand, covering the turbine housing with a blanket means preventing heat radiation on the compressor section of the turbo and the air inlet, keeping the intake air cool. The cooler the air is, the more dense it is, and the more oxygen it contains per unit volume. In this way more oxygen reaches the combustion chamber and enables more fuel to be burned, increasing combustion efficiency and providing improved power output.

icon  2° TRACK: “All right now”

icon You keep your engine compartment in GOOD SHAPE since all sensitive components are protected from radiated heat and can continue to run healthy. 
Tmax-Turbo Blanket contains the heat in the turbine housing, preventing it from reaching and damaging temperature-sensitive components like plastic and rubber hoses, electronic parts and electrical wirings, extending their life and improving their reliability.

icon  3° TRACK: “Shine on you crazy diamond”

icon You enjoy the paint job for a longer time since the turbo blanket helps prevent PAINT DAMAGE from heat. 
Preventing the heat in the turbocharger from dissipating in the engine compartment means protecting painted surfaces like the hood, firewall or wings, thus avoiding fractures/cracks and damages to the paint. These parts are actually not designed to withstand great changes in temperature.

icon You enhance the APPEARANCE of your engine compartment since a turbo blanket looks good. 
A Tmax-Turbo Blanket simply makes your engine bay look gorgeous … ready to rock the scene.
