Design Highlights:
-
Self-Balancing Valve: The zero-offset butterfly valve is balanced against exhaust drive pressure on both sides, enabling central pivoting and reducing the effort needed to actuate against high pressures. This results in a wide tuning window and enhanced performance.
-
Increased Flow: The straight-through valve design eliminates the need for the exhaust gas to turn 90 degrees, improving flow efficiency over traditional poppet-style valves.
The StraightGate50 is engineered for maximum flow, control, and simplicity, setting a new benchmark in wastegate performance.
