Turbosmart Pneumatic Straight Gate 6psi External Wastegate

The StraightGate50 is the highest flowing wastegate on the market by its efficient butterfly-style valve and straight body, meaning the exhaust gas is no longer required to be turned 90 degrees like in the case of a traditional poppet-style gate. The zero-offset and self-balancing butterfly-style wastegate mean a greater tuning window with over five times base spring pressure achieved with external boost control and truly advanced strategies for the vacuum-based units, including the ability to mean and improve emissions compliance.

This vacuum-based unit uses the vIWG Vacuum Internal Wastegate Actuator Series which relies on the vacuum based architecture. This unit features a 6inHG spring and includes a twin port option for advanced strategy, including the ability for boost-assist via the second chamber.

Unlike the Electronic StraightGate50, which requires an advanced control strategy, the Pneumatic Series of StraightGate50 requires fairly common control strategies. A simple Boost-Tee will run great results from the Boost-Based version, while traditional Vacuum-Based strategies will work perfectly on the Vac-Based StraightGate50. It’s simple reference manipulation and controlled bleed – the kind of boost control that has been commonplace for decades.

The VBand allows rotation through 360 degrees with no impact on valve operation. Furthermore, the Billet Actuator bracket can be clocked to any of the three options provided by the 3-pin mounting system, providing a huge range of mounting options to fit into even the most complex and packed modern engine bay. There are design elements to ensure the least heat transfer possible into the diaphragm housing, and Turbosmart has validated this to 1300 Degree C with no impact on performance and reliability. These units are best mounting in the manifold prior to the turbocharger in the stream of the full exhaust flow for best control.
