That is not my understanding. The Theory is they keep heat OUT of the parts. They CAN, on engines with VERY little deck clearance, reduce combustion chamber volume enough to case trouble. From the Techline site (vendor claims, so discount them accordingly, but Techline has been around a long time, and has been used by a lot of people):Internal coatings will result in the surfaces being hotter. That will need a CR drop. That will reduce the cycle efficiency and power you get. I'd rather use water injection.
POWERKOTE™ CBC-1 CERAMIC THERMAL BARRIER COATING
- Combustion chamber coating for all metals.
- Excellent for piston tops.
- Thermal barrier/heat management
- Reduces part temperature. Protective to above 2000°F.
- Keeps heat in combustion chamber longer through the power stroke.
- Blurs hot spots. Reduces the potential for detonation.
- Highly resistant to thermal shock. Survives cyclic heating and cooling.
- Increase torque and Horsepower
- Increase combustion chamber efficiency.
- Reduce fuel consumption.
Bob also used water - spraying it on the outside of the radiator of his overloaded Toyota pickup! Great for getting up long grades in the dessert in the summertime.
