Supertech Performance Valves

Don't build your engine with inferior parts! Supertech valves are the best on the market, made from one piece of forged stainless steel for the ultimate in strength and durability. Supertech valves go through a special heat treatment process that obtains the right amount of harness for each engine to ensure the ultimate valve for your performance motor. Supertech offers their valves in either chrome coating, used in high performance valves, or hardened black nitrided which is most popular in European and Japanese motors.

Supertech High Performance Race Engine Valves features:
  • The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer (microhardness is 800HV minimum)
  • Surface finish is smoother than with chromed stems, having less friction between stem and guide.
  • Valve seat surface is harder with the nitrided layer, lasting longer with lead free fuels, alcohols, nitro or other "explosive" mixes. Matches any kind of seats (nodular iron seats, steel powder metal seats, hard aluminum-copper seats or beryllium copper 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 brake 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.

What is the difference between the Black Nitride valves and the Inconel valves? Can the inconel valves be used on the intake side?
The black nitride valves are stainless steel valves, with a black treatment that hardens the valves. The inconel valves are made from a Nimonic 751 alloy which has better resistance to heat than stainless steel. The inconel valves are only used on the exhaust side, it is the only side that is needed to use a higher temperature alloy.

What is the hardness of the Nitride layer on the valves?
The nitrided valve harness is about 800 Vickers - equivalent to 52 Rc (equivalent because it is just a thin layer).

What are the operating temperatures of the valves?
Our stainless valve has a 1,460F (approx 1900 F EGT). The Inconel valves have a 1600 F (Approx 2200 F EGT)

What is the durability of the titanium valves?
Depends on many factors like operating temp, seat hardness, rms, etc, but a reasonable number is 1000 miles in a racing application.

SUPERTECH Racing components for the Nissan GT-R 2007-2011

Supertech is now offering high quality one piece forged Intake valves in stainless steel that stands out for its precision and consistency. The Black Nitride heat treatment provides less friction for less power absorption and better heat dissipation than chromed valves. Exhaust valves in INCONEL high temperature alloy for Turbo charged applications. Available in 1mm oversized.

Dual Valve springs kits are made with premium Super Clean Chrome Silicon Vanadium Steel alloy for higher performance & durability. Titanium retainers CNC machined, Steel Seat locators. Offered in two different spring set-ups for higher RPM and boost applications.

Also available are Solid lifters, Completely CNC machined from heat treated billet provides only the necessary and calculated thickness of the walls with very special shapes, providing better rigidity with an important reduction in weight

The Black Nitride heat treatment provides less friction for less power absorption and better heat dissipation than chromed valves. Exhaust valves in INCONEL high temperature alloy for Turbo charged applications. Available in Standard size and 1mm oversized.

Dual Valve springs kits are made with premium Super Clean Chrome Silicon Vanadium Steel alloy for higher performance & durability. Titanium retainers CNC machined, Steel Seat locators. Offered in three different spring set-ups for higher RPM and boost applications.

High performance standard & oversized Pistons, manufactured from extruded high silicone enhanced 4032 alloy that has low thermal expansion. Coated with a Phosphate dry lubricant coating to protect rings against micro welding and enhance lubrication on the skirt and cylinder area.

EVO X Press Release

SUPERTECH is offering high precision EVO X Stainless Steel Nitrided Intake valves and Inconel high temperature alloy Exhaust valves in standard and +1mm head diameters. The superfinished valve stems have a very low surface roughness for low friction and the extremely tight excentricity tolerance of the head and nitrided treatment will provide a long durability and sealing properties. More valvetrain components will be available soon
