Description
Turbosmart Electronic StraightGate ESG50 External Wastegate
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!

What is the first rule of boost control?
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.
How fast is the eSG50 StraightGate50?
Fast. Full Valve Actuation can be achieved in 63ms.
What do I need to do to Control it?
<>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.
Can I rotate the Actuator Housing?
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.
What Spring Options does the eSG50 have?
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.
