Are Turbo Blankets and Ceramic Coating Worth Your Time?
Posted by Joe Neill on 27th Jan 2022
We often get asked about turbo blankets and ceramic coating on our manifolds and turbine housings, so I thought I would take a second to explain what these heat coatings and blankets actually do.
First we need to start with the basics properties of gasses and thermal properties.
It's common knowledge that things can expand and contract when temperatures change; What's going on in your new turbocharger is no different! On the exhaust side, as the exhaust gas temperature rises, the gasses expand. This expansion generates additional pressure. Additional pressure raises the velocity of the exhaust gasses. Thus you have more abundant and quicker moving velocity. These scenarios combined result in more and more readily available energy to drive the turbine wheel, which means boost comes on faster and turbo lag is decreased.
Now that we understand the thermal properties and how they directly affect performance, let's talk about ways we can take advantage of what we know.
Ceramic Coating: Not only does ceramic coating make the engine bay more uniform looking and aesthetically pleasing, it's a great way to keep heat inside the manifold.
Blankets: Specially made blankets of Kevlar and other materials are another great way to keep the heat in.
Wrap: This has a similar effectiveness and is by far the cheapest option, but can lead to rust and corrosion from holding moisture in.
Aside from the performance benefits of blankets and ceramic coating, there are a few others worth noting:
Aesthetics: A blank on a rusty turbine housing really does alot to clean up an engine bay. Same goes for ceramic coating on the exhaust manifold or turbine housing. Dressing up the engine bay may not have an effect on efficiency, but its something worth wild if you take pride in your machine, especially considering its also providing performance benefits!
Protection: While this may not be as much of a factor on our big truck builds, heat protection is very important in smaller packed applications like cars. The heat from turbine housing, down pipe, or exhaust housing can easily damage other components in the engine bay without proper heat shielding.
Bottom Line: Blankets and ceramic coating are not required, but for folks looking for a little extra from their setup, its an easy gain! If you have any other questions, about blankets, ceramic coating, or turbos - give us a shout!

Cummins N14/855 Upgrade Turbo
The factory HT60 on the Cummins N14 and 855 engines has a unique flange pattern and abnormal mounting orientation that makes it very difficult to retrofit a more modern upgraded turbocharger.With this in mind, we set out to create an upgrade that was a direct replacement from an installation stand point. Depending on the original [...]
Turbine Housing Explained | Which A/R works best?
A/R stands for Area over Radius. Area is the size of the housing inlet and radius is the the diameter of the housing. Before every keyboard warrior jumps down my throat...this is just a basic explanation for the sake of a general overview -we don't need to get lost in the weeds, we'll leave that [...]
Cummins ISX VGT Turbo | NEW Aftermarket Direct Replacements
The VGT turbo is nothing new to the Cummins ISX engine, since the introduction of the VGT style turbo on the CM870 ISX in 2003, each new rendition of the ISX has come with a VGT turbo. The latest ISX models, CM2250, CM2350, and X15 have the HE451VE turbo with electronic actuator from the factory. These [...]
CAT C15 Acert SDP Ball Bearing Turbo Cartridges
The SDP C15 Acert arguably has the best set of compound turbos ever put on a Caterpillar from the factory, the Garrett GTA5518BR and GTA4294BRS. What makes these turbos so great? BALL BEARINGS :) The compound ball bearing turbos on SDP engine serial prefix engines is easily identifiable by the fins on the cartridge (used [...]

If you have a 2008-2011 trucks with a Detroit Series 60 engine, your turbo salvation has arrived! The DDEC VI was the last Series 60 configuration available before being replaced by the DD15. While Detroit primarily used Garrett turbos on their series 60 engines, emissions regulations in 2007 pushed Detroit into switching to a VGT turbocharger [...]
New Turbos Vs Reman Turbos
New Turbos Vs Reman TurbosLet's start this conversation out with the most common argument for purchasing a reman over new: reman turbos are cheaper. Sure, the initial invoiced price for a reman turbo might be less then a new - but is it REALLY cheaper in the long run?Let's find out..As an example let's [...]
