The GT Wastegate is the highest flowing of the HKS Wastegates. Its 60mm diameter valve is design to accommodate high output applications producing from 600 horsepower to well beyond 1000 horsepower. The adjustable rate GT wastegate spring is specifically engineered to provide ample resistance to the extreme exhaust pressure developed by these high output applications. The enhanced diaphragm and spring design being provides stable consistent boost levels by preventing the valve from over opening and releasing exhaust energy. Despite its complex structure, the GT Wastegate is a very compact unit that utilizes a V-band inlet and outlet structure that provides extremely smooth flow characteristics and better sealing at high temperatures. The use of V-band clamps also offers extremely versatile mounting and adjustment options for custom applications.
