eSG40 Electronic StraightGate 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 which allows enormous flow and almost linear control with unparalleled boost control throughout the entire operating range.

_x000D_ Turbosmart’s eSG40 Electronic StraightGate is a Patent Pending and based on the success of the Multiple Award Winning, World First eSG50 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 Electronic StraightGate40 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.

_x000D_ 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 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.
