Turbosmart PSG40 Pneumatic Straight Gate 6psi Black

\n\t\t\n\t\t
\n\t

The StraightGate40 from Turbosmart is the smallest butterfly-style external wastegate for tight engine bay confines and fitment. The StraightGate40 is a zero-offset butterfly-style wastegate that allows enormous flow and almost linear control with unparalleled boost control throughout the entire operating range. 

\n

The Boost-Based Pneumatic StraightGate40 takes the Multiple Award Winning eSG50, shrinks it, and simplifies control via a traditional boost-based actuator. The Self-Balancing nature of the StraightGate means a huge tuning window of over 5 times base spring pressure can be obtained! Pre-fitted with 6 psi springs to the GenV actuator featuring both single and twin port control, the StraightGate50 is simple to use, and packed with performance, flow and features! 

\n

The Turbosmart StraightGate40 has been designed from the ground up and validated in-house to create a new level of control and flow, never seen in a wastegate before. The zero-offset butterfly valve is subjected to exhaust drive pressure equally on both halves of the valve, which pivots centrally, resulting in a self-balanced valve against any drive pressure. This self-balancing means less work is required to act against even the highest drive pressures, and a wider tuning window is possible, no matter how the valve is actuated. The increased flow is achieved through the efficiency of a straight-through valve versus a poppet-style valve, where the exhaust gas must be turned 90 degrees by the valve.

Turbosmart


Smarter Turbo Control, by Design

Turbosmart is an Australian manufacturer of high-performance forced induction accessories, built around a simple but powerful idea: turbo control should be smarter, more precise, and more reliable than the standard solutions the industry has traditionally offered. Founded on genuine passion for performance, the brand has grown into a globally recognised name in the forced induction aftermarket, trusted by racers, tuners, and enthusiasts across the world who demand products engineered to win and built to last.

A Global Standard, Set in Australia

Turbosmart's vision is straightforward: to be the first choice worldwide for forced induction upgrades across both performance and service industries. That ambition is backed by a product range that spans everything a turbocharged vehicle demands, from street-performance daily drivers to dedicated full race builds requiring the highest levels of boost control precision. With a growing international presence and brand advocates spanning tracks and workshops across the globe, Turbosmart has firmly established itself as a name that resonates far beyond its Australian origins. Their in-house engineering department also takes on complex industrial applications where the same hallmarks of their racing pedigree, precision, heat management, vibration control, and repeatability, translate directly into real-world solutions. It is this ability to operate at the cutting edge of both motorsport and industry that keeps Turbosmart at the forefront of forced induction technology worldwide.

Designed, Tested, and Manufactured In-House

Every Turbosmart product is designed, rigorously tested, and manufactured entirely in-house, ensuring that quality and performance are never compromised by external variables. Their engineering team applies a motorsport-first development philosophy, if it cannot survive the demands of competition, it does not reach the market. The result is a range of boost controllers, wastegates, blow-off valves, and turbo accessories that consistently raise the benchmark for boost control efficiency, durability, and precision across a wide range of turbocharged platforms.
