Turbosmart's StraightGate is the most efficient external wastegate in the world! The StraightGate is a zero-offset butterfly valve that allows for enormous flow and near-linear control with unrivaled boost control across the entire operating range.

Turbosmart's electronic StraightGate is patent pending and is based on the success of the world's first and multiple award-winning eSG50 butterfly-type external wastegate. The absence of reference pipes, springs and diaphragms means fully electronic control through a servo motor and Turbosmart's feedback-free gearbox, resulting in lower current demands as well as operational stability in the face of enormous driving pressures. The eSG includes onboard sensors covering actuator temperature as well as valve position, both analog and digital. Electronic actuation provides the widest possible tuning window, from zero boost (manifold priority permitting) to all available boost.

The Turbosmart StraightGate was designed from the ground up Z and internally validated to create a new level of control and throughput, never seen in any wastegate before it. The zero offset butterfly valve is subjected to exhaust pressure equally on both halves of the valve which pivots centrally, resulting in a valve that is self-balancing against any driving pressure. This self-balancing means that less work is required to operate it, even against the highest drive pressures, and it is possible to achieve a wider adjustment window, regardless of drive pressure.
