Product Overview

Supertech - Sport Compact - SEVN-1010 - Subaru - Exhaust Valves

Made as a one piece forged valve for higher strength and reliability.We use mostly EV8 (21-4N) for Intake and Exhaust valves but there are other alloys that we use along with different heat treatments to manufacture valves for different applications.Other hard metal alloys may be welded to harden certain areas like the tips or seats.Higher rpm's engines take full advantage of all previous features. The higher the engine speed the bigger the power loss due to internal engine friction! The black nitride layer reduces this power loss due to less valve-guide friction.The nitrided layer is adhered to the base material at a microscopic level, so does not "flake" or break when the valves bend due to impacts with the pistons.The Black Nitride applies to the whole valve while the chrome coating is only applied to the stem.All valves are swirl polished, have stem undercut and a hardened tip.
