Electronic StraightGate ESG50 External Wastegate – TS-0565-1002

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!

Developed off the back of Turbosmart’s SEMA 2019 New Product Award Winning eWG range with full electronic actuation and control, the StraightGate50 features an in-house designed, CFD driven and real world validated butterfly valve style external wastegate which provides all the benefits of over two decades of boost control experience with the latest technology for truly advanced boost control strategies with virtually no limits.

The valve body is non-direction and can be installed radially through 360 degrees on the V-Band. The actuator housing can also be located in any of the 3 clocking positions for truly versatile fitment.

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.

Incorporating Turbosmart’s Zero-BackDrive technology means the valve consumes no current while stationary reducing overall current requirements and ability against high drive pressure levels never before seen.
