Ceramic Coated Heads

By applying a Ceramic coating to the combustion chambers, runners, valve stems the heat of the combustion stays in the cylinder allowing more power to drive the piston in turn driving the turbo harder. 


The coating in the runners is a "Heat Stop" it prevents the exhaust gasses from transferring into the head slowing heat soaking.

Valve unshrouding

Our custom CNC valve unshrouding increases flow by opening up the area around the valve seat allowing for faster air movement at early valve lift through full lift increasing flow.

We offer top quality piston coatings. For any needs from street, turbo, diesel, to nitro. We can provide Thermal Barriers, Thermal Dispersants, Dry Film Lubricants, even skirt & bearing buildup when tolerances need to be tightened up.

Runner Coating

Diesel, gas, turbo, it doesn't matter all engines could benefit from a Thermal Barrier in the runners, this coating will slow and almost stop heat transfer into the heads making the motor run cooler and sending harmful heat out the pipes where it belongs.
