Hey Eldartford, glad you set those silly folks at NASCAR straight on cryo process.
Cryogenic processing is now being used by NASCAR and other racing teams. They have taken advantage of this treatment to reduce wear of their engine components and increase horsepower which are important to their crossing the finish line. Some of the engine components treated include blocks, push rods, valves, camshafts, brake rotors, crankshafts, heads, and even spark plugs and spark plug wires.Cryo
