Combine this experience with state of the art equipment such as ultrasonic tests, x-rays, laser measurement equipment, and applications like computerized Finite Element Analysis (FEA) and it is no wonder why Supertech has some of the best performance products on the market. Supertech also does extensive testing working very closely with many of today's top engine builders in order to continuously improve products. All of this is meant to insure Supertech's industry leading reputation for high flow rates, durability and uncompromising quality. Higher Flow RatesSupertech valves are not finished from generic blanks rather they are specifically designed for each and every application. Supertech works relentlessly, testing and researching every aspect trying to improve the air flow of their designs. DurabilityWith every valve design, Supertech strives to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc. Stem Super finishingIn 2006, Supertech introduced the stem Superfinishing as a standard addition to all valves and provided it at no additional cost. When Superfinish is combined with our Black Nitrided valve it reduces the surface roughness to 1/3 of a chrome coated valve. The end result... unsurpassed performance and durability. Strict Dimensional Tolerances It's unlikely you will find any of competitor valves with stricter dimensional tolerances than Supertech valves. Combine that with finished seats with equally strict run out tolerances and you won’t find a better sealing, better performing and easier to install solution anywhere!
