Turbosmart StraightGate50 Vacuum-Based Pneumatic External Wastegate
The Turbosmart StraightGate50 Vacuum-Based Pneumatic External Wastegate is a high-flow, butterfly-style external wastegate engineered to deliver exceptional boost control across the entire operating range. Its innovative 50mm zero-offset butterfly valve provides almost linear control and industry-leading flow, while the vacuum-based GenV actuator supports advanced boost strategies, including cold-start emissions control and compatibility with factory vacuum-operated boost control systems. The self-balancing valve design reduces actuator effort under high exhaust drive pressures, providing a wider tuning window and consistent boost regulation for high-performance street and motorsport applications.
