Overview

Turbosmart StraightGate50 Pneumatic Wastegates

Turbosmart StraightGate50 vacuum wastegates are zero-offset butterfly-style units that allow enormous flow and almost linear control, and unparalleled boost control throughout the entire operating range. These high-flowing wastegates are simple to use, and packed with performance, flow, and features.

The zero-offset butterfly valves are 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 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.

Turbosmart pneumatic StraightGate 50s are available in a boost-based pSG50 6 psi or vacuum-based pSG50v 6 InHg versions. Both pneumatics take the electronic eSG50 version and simplify control via a traditional boost-based or vacuum-based actuator. Select the one you prefer.
