PSG40 Pneumatic Straight Gate 6psi Black

The StraightGate40 from Turbosmart is the smallest butterfly-style external wastegate for tight engine bay confines and fitment. The StraightGate40 is a zero-offset butterfly-style wastegate that allows enormous flow and almost linear control with unparalleled boost control throughout the entire operating range. 

The Boost-Based Pneumatic StraightGate40 takes the Multiple Award Winning eSG50, shrinks it, and simplifies control via a traditional boost-based actuator. The Self-Balancing nature of the StraightGate 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 StraightGate40 has been designed from the ground up and validated in-house to create a new level of control and flow, never seen in a 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 self-balanced valve against any drive pressure. This self-balancing means less work is required to act against even the highest 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 poppet-style valve, where the exhaust gas must be turned 90 degrees by the valve.
