Supertech Performance Valvetrain Quick Facts

by James Innes

Here some Supertech Performance Quick Facts:

  • Our stainless valve has an operating temperature of 1,460 F. (approximately 1900 F EGT) The INCONEL valves have and operating temperature of 1,600 F (approximately 2200 F EGT)
  • The Nitrided Valve hardness is about 800 Vickers = equivalent to 52 Rc (equivalent because is just a thin layer).
  • Our Piston material 4032 alloy expands 18% less than 2618 alloy.
  • Our Cam Followers require the use of shims. The 8mm shims are sold seperately, and one should always measure the clearance between cam and valve tip to know what size shims are needed.
  • 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 then the stainless steel. The Inconel valves are only used on the exhaust side, it is the only side that it is needed to use a higher temperature alloy.
