The StraightGate50 eSG50 from Turbosmart is a 50mm (1.97in) butterfly valve style external wastegate for turbocharged engines. The StraightGate50 provides more flow than any conventional 60mm poppet style valve while also providing more control and almost linear response for unparalleled boost control throughout the entire operating range. This is Boost Control re-imagined!
Thermally stable and tested to 1250°C / 2280°F the eSG50 is capable in the most demanding environments while providing control never before seen before via liquid cooling and the inclusion of a ceramic thermal insulating spacer between the actuator and valve body. The onboard temperature & position sensor outputs allow for advanced control strategies.
This StraightGate50 50mm Valve provides the control of a smaller 40mm valve, with flow exceeding that of a traditional 60mm valve. Teamed with Electronic Actuation, all the limitations of traditional boost control are a compromise of the past. With appropriate manifold priority, these valves can provide 100% bypass for zero boost up to maximum boost and do so faster than any valve before it – Full valve actuation can be performed in 63ms and provide an unparalleled tuning window.
