The StraightGate50 from Turbosmart is the Award Winning, World’s first butterfly style, Electronic external wastegate! The StraightGate50 is a zero-offset butterfly style wastegate which allows enormous flow and almost linear control with unparalleled boost control throughout the entire operating range.
Turbosmart’s eSG50 Electronic StraightGate is a Patent Pending, Multiple Award Winning World First Electronically Actuated Butterfly Style External Wastegate. No reference hoses, no springs and no diaphragms means full electronic control via a servo motor and Turbosmart’s zero-backdrive gearbox which results in lower current demands as well as operation stability against huge drive pressures. The eSG50 includes onboard sensors covering actuator temperature as well as valve position in both analog and digital. The Electronic actuation results in the widest possible tuning window from zero boost (if manifold priority allows for it) to all available boost.
The Turbosmart StraightGate50 has been designed from the ground up & validated in-house to create a new level of control and flow, never seen in any wastegate before it. 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.
