Supertech manufactures a variety of high performance Inconel valves for many applications. These valves are manufactured from a Nickel base super alloy material (Inconel 751 or Nimonic 80A) this material is chosen because it is designed to withstand very high temperatures. These valves feature a one-piece forging, hardened tip, and our “superfinish” stem. Our Inconel valves are extremely popular choice for turbo and supercharged applications.
Supertech Sodium Filled Valves made of Inconel / Nimonic Alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines.
A Cooler Valve improves the material strength and durability while allowing the tuner more flexibility and a wider range of spark timing advances. Combine that with an average weight reduction of 10% and there isn’t a cooler valve on the market
