SUPERTECH Black Nitried Intake Valves BMW/PSA 1.6 Turbo. Set of 8 pcs valves with single groove keepers. Supertech stainless steel intake valves are manufactured from an enhanced version of EV8 (21-4N) steel.
We have chosen this material specifically because it's the highest grade of steel available and provides the strength to withstand just about any application. Our exhaust valves are made from EV16 (21-8N) or EV8-Nb/w for even greater strength at higher temperatures. Our stainless steel valves are one piece forged valves, and depending on the application feature hardened tips, hardened seats, swirl polish, undercut, and our black nitride coating. Supertech black nitride coated valves feature a harder surface area and a smoother finish, providing less friction and subsequently longer life.
Supertech apply more than 30 years of experience in the development of each and every Supertech racing valve we sell. 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. While this is more than most manufacturers we don't stop there. We also do extensive testing working very closely with many of today's top engine builders in order to.All of this is meant to insure Supertech's industry leading reputation for high flow rates, durability and uncompromising quality. Our valves are not finished from generic blanks rather they are specifically designed for each and every application. We work relentlessly, testing and researching every aspect trying to improve the air flow of our designs. With every valve design we strive to maximize durability through higher fatigue resistance and tensile strength. Each valve tip is hardened beyond 52HRc.
In 2006 we introduced our stem Superfinishing as a standard addition to all of our valves and provided it at no additional cost. When our Superfinish is combined with our Black Nitrided valve it reduces the surface roughness to 1/3 of our chrome coated valve. It's unlikely you will find any of our competitor's valves with stricter dimensional tolerances than our 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!
