Turbosmart Straight-Gate 50 External Electric Wastegate – 50mm (Part #TS-0565-1002)
Next-Level Boost Control Without Springs or Hoses
Traditional wastegates rely on springs and reference hoses to manage boost. They work, but they are limited. Boost response is inconsistent. Spring choices limit your tuning window. Reference lines are prone to failure.This is the Turbosmart Straight-Gate 50 Electric Wastegate. Part #TS-0565-1002. 50mm. Electronic actuation. No springs. No diaphragms. No reference hoses.It is the world's first electronically actuated butterfly-style external wastegate . It won multiple awards for a reason. It is the highest-flowing external wastegate on the market . The difference is immediate. Boost control is precise. Consistent. Tuneable.Why Butterfly-Style?
Traditional wastegates use a poppet valve. Exhaust gas must turn 90 degrees to exit. That creates restriction. The Straight-Gate uses a zero-offset butterfly valve . The valve pivots in the center. Flow goes straight through. Smooth. Efficient. The flow rating is 383.9 CFM . That is massive.The butterfly design is self-balancing. Exhaust drive pressure applies equal force to both halves of the valve . The valve stays stable against even the highest drive pressures. The actuator does not have to fight the exhaust flow.How Does Electronic Actuation Work?
The eSG50 uses a servo motor and a zero-backdrive gearbox . The control system is a dual H-bridge input. It includes onboard sensors for actuator temperature (0-5V analog) and valve position (0-5V analog and PWM digital) . You get real-time feedback. You can tune boost precisely. The tuning window is the widest possible. From zero boost to all available boost .The system includes a 7-wire unterminated flying lead loom . You integrate it into your engine management system.Built To Last
The main body is cast stainless steel (347) . The butterfly and shaft are heat-treated stainless steel (630) . The V-band clamps are heat-treated 431 stainless steel . The black anodized top is 6061-T6 aluminum. The actuator uses liquid cooling for stability .Features & Benefits

Vehicle Fitment
Universal fitment for turbocharged vehicles with a 50mm wastegate flange. Requires an engine management system capable of controlling a dual H-bridge actuator. The weld-on flanges included allow custom fabrication to suit your specific setup.What Is In The Box?
Electronic Straight-Gate50 wastegate. Inlet and outlet V-band flanges. Inlet and outlet weld flanges. 7-wire unterminated flying lead. Turbosmart decal .FAQ
What is the difference between the electric and pneumatic versions?
The eSG50 uses electronic actuation. No springs. No hoses . The pneumatic version uses a traditional boost-based actuator with 6 psi springs . The electric version offers the widest tuning window and most precise control. How do I control the eSG50?
You need an engine management system capable of controlling a dual H-bridge actuator. The 7-wire loom provides power, ground, and signal connections. The onboard sensors provide feedback for closed-loop control . Does this wastegate require a spring?
No. The electric version uses a servo motor and gearbox. No springs required .What is the flow rating of this wastegate?
383.9 CFM (10.87 m³ per minute) .Does this wastegate come with a solenoid or controller?
No. The wastegate is the actuator assembly. You supply the control system through your engine management.

Precise boost control right from the cab. the ESWG50 responds quickly and holds target pressure consistently. Great upgrade for any boost setup.
Carlos Tenesaca –
Finally got boost control dialed in on my turbo build with this electronic wastegate. The response is fast and consistent. I can hit my boost target lap after lap without creep or instability. The construction is solid and it handles the heat near my turbine housing without any issues. My tuner was impressed with how cleanly it integrated into my setup. Boost curves are now exactly what I programmed. If you’re serious about a quality turbo build, this wastegate is the right component.

Added this electronic wastegate to my turbo setup for more precise boost control and the difference in consistency is immediate. Boost holds steady run after run instead of the creep I had with my old mechanical gate. Response time is fast enough that my tuner had no trouble mapping it smoothly across the RPM range. Build quality feels serious, no leaks or chatter under load. Install required some plumbing work but the included hardware made it manageable in my home garage. Excellent upgrade for anyone serious about boost control.
