ESG50 StraightGate50 by Turbosmart
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 three clocking positions for truly universal fitment.
ESG50 StraightGate50 Thermally tested to 1250°C / 2280°F
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 controls a smaller 40mm valve, with flow exceeding that of a traditional 60mm valve. Teamed with Electronic Actuation, all the limitations of conventional 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. Full valve actuation can be performed in 63ms and give 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.

Frequently Asked Questions
Ensure you have an over-boost cut-out. This is a safety feature built into basically all factory, aftermarket & programmable ECU’s. You can never be too careful. Make sure it is set at a sensible & reasonable limit. Increasing the boost will put more load on your engine and there are other tune related factors you must consider. If in any doubt, speak with a professional tuner / calibrator.
Fast. Full Valve Actuation can be achieved in 63ms.
You will need a programmable ECU (Engine Control Unit) and a ‘High Current’ (20Amp) output H-Bridge output. This can be done on some ECU’s (speak with your manufacturer) or, via an external H-Bridge module. The Turbosmart BlackBox is available as an external driver which can be controlled via recalibrated / programmable factory ECU’s (Via traditional PWM boost control output) or with a programmable aftermarket ECU via PWM, 0-5v Analogue output or with CAN based override.
Yes. There are 3 clocking options to choose from. The valve body itself is also rotatable on the V-band axis and is non-directional so you have huge flexibility with fitment.
Just the one – None. The Turbosmart eWG series is fully adjustable without the need for springs. It can actuate against extreme levels of drive and backpressure and does so without any springs at all. There is nothing to change, ever. IT also features our ‘Zero BackDrive’ technology to further bolster its ability against high drive pressures. This means the largest tuning window possible with no minimum boost pressure limitations of traditional wastegate systems.
Here is a handy self-help guide to helping you with your Turbosmart install and answers to some of the most frequently asked questions we get here. Turbosmart recommends that you get your products fitted and tuned by a qualified technician. If you choose to install the product yourself, ensure you have all the necessary tools and technical knowledge to perform this task.
