Speedway Illistrated Discussion

Speedway Illustrated Magazine
An article has appeared in this magazine discussing the advantages to be found in using Thermal Barrier Coatings authored by David Vizard. It includes information on the benefits to be found in coating intake manifold bottoms as well as coating the intake runners. By coating these surfaces you can effectively reduce the intake temperature as well as reduce the heat that can be absorbed by the air or air / fuel mix as it passes through the runners.
An additional point was made about the gain that can be seen by coating the intake valve. The incoming air/fuel mixture will pass over the valve just before entering the combustion chamber. When the mix passes over the valve it will pick up heat that has been absorbed by the valve, during combustion. This can lead in extreme cases to detonation. In less extreme cases it still can reduce power. Coating the valve reduces the heat absorbed and contributes to a "cooler" air fuel mix, which means a greater power potential. Wheel Coatings
There is a great deal of interest in wheel coatings. This is of special, interest to Circle Track competitors as wheel and tire temperatures are critical. Tech Line Coatings has been recommending a variety of coatings for wheels. By choosing the proper coating wheel, tire and break temperatures can be controlled to a beneficial degree.
