Turbosmart Electronic StraightGate 76 External Wastegate
Fits Most Models
TS-0567-1002
Overview:
The Turbosmart Electronic StraightGate 76 (eSG76) is the world’s highest flowing external wastegate, engineered to deliver unparalleled boost control and exceptional flow capacity. Designed for performance enthusiasts and professional tuners alike, this advanced wastegate replaces traditional mechanical components with full electronic actuation, offering precise and linear boost management across the entire operating range.
Whether you are building a high-horsepower turbocharged setup or seeking the ultimate in boost control stability, the StraightGate 76 provides a reliable, tunable solution that enhances your vehicle’s performance and responsiveness. Its innovative design ensures consistent operation even under extreme exhaust drive pressures, making it ideal for demanding street, track, or race applications.
Key Features:
The Turbosmart StraightGate 76 combines cutting-edge technology with robust construction to deliver superior performance and durability. Key features include:
- 76mm (2.99 inch) butterfly-style zero-offset valve for maximum flow efficiency
- Exceptional flow capacity rated at 723.7 CFM (20.49 m³/min), the highest in its class
- Full stainless steel construction: 630 stainless steel butterfly and shaft, 347 stainless steel main body, and heat-treated 431 stainless steel V-band clamps
- Zero-offset butterfly valve design that pivots centrally, creating a self-balanced valve that resists exhaust drive pressure equally on both halves
- Full electronic actuation via a servo motor and Turbosmart’s zero-backdrive gearbox, eliminating the need for reference hoses, springs, or diaphragms
- Onboard sensors providing analog (0-5V) actuator temperature and valve position feedback, plus a PWM digital valve position sensor for precise monitoring
- 360-degree mounting options on the V-band with clockable actuator position offering three 120-degree orientation choices
- Liquid cooling system for actuator stability under high-temperature conditions
- 7-wire unterminated flying lead loom for flexible wiring and integration
Construction & Design:
The StraightGate 76 is meticulously engineered from premium stainless steel alloys to withstand harsh exhaust environments and high temperatures. The zero-offset butterfly valve design allows exhaust gases to flow straight through without the 90-degree turn required by traditional poppet-style wastegates, significantly improving flow efficiency and reducing backpressure.
The valve’s self-balancing mechanism reduces the force needed to actuate against high exhaust pressures, resulting in smoother operation and a wider tuning window. The robust electronic servo motor and zero-backdrive gearbox ensure stable, low-current operation and precise valve positioning, even under extreme boost conditions.
Performance & Sound
- Delivers the highest flow capacity available in an external wastegate, supporting increased horsepower and torque potential
- Enables near-linear boost control across the entire boost range, from zero boost (if manifold priority allows) to maximum available boost
- Improves throttle response and boost stability by eliminating the lag and variability associated with mechanical wastegate actuation
Installation & Fitment:
The Turbosmart Electronic StraightGate 76 is designed to fit most turbocharged vehicle models, offering versatile mounting options with its 360-degree V-band clamp. Its clockable actuator position allows for easy orientation to suit various exhaust layouts.
Installation requires integration with your vehicle’s electronic boost control system via the included 7-wire flying lead loom. The wastegate comes with a detailed installation guide to assist with setup and wiring. No cutting, drilling, or special tuning is required beyond standard boost controller calibration.
