The StraightGate 50 from Turbosmart is the world's highest flowing external wastegate! The StraightGate 50 is a zero-offset butterfly style wastegate which allows enormous flow and almost linear control with unparalleled boost control throughout the entire operating range.
The Boost-Based Pneumatic StraightGate50 takes the multiple award winning eSG50 and simplifies control via a traditional boost-based actuator. The Self-Balancing nature of the StraightGate50 means a huge tuning window of over 5 times base spring pressure can be obtained! Pre-fitted with 6 psi springs to the GenV actuator featuring both single and twin port control, the StraightGate50 is simple to use and packed with performance, flow and features!
The Turbosmart StraightGate50 has been designed from the ground up and validated in-house to create a new level of control and flow, never seen in any wastegate before. The zero-offset butterfly valve is subjected to exhaust drive pressure equally on both halves of the valve which pivots centrally, resulting in a valve that is self-balanced against any drive pressure. This self-balancing means less work is required to actuate against even the highest of drive pressures and a wider tuning window is possible, no matter how the valve is actuated. The increased flow is achieved through the efficiency of a straight through valve versus a traditional poppet style valve where the exhaust gas must be turned 90 degrees by the valve.
