On a turbocharged engine, building boost fast is the name of the game. However, making too much boost can lead to disaster. That’s where the wastegate comes in to save the day!
Inside of a wastegate is a spring pressing against a diaphragm. Once the pressure of the air leaving the compressor exceeds the pressure of the spring, it moves the diaphragm, which is linked to a bypass valve before the exhaust turbine. The bypass opens, and some of the exhaust gas pressure is released into the exhaust (or, on some race vehicles, the atmosphere), mitigating boost.

On a turbocharged engine, building boost fast is the name of the game. However, making too much boost can lead to disaster. That’s where the wastegate comes in to save the day!
Inside of a wastegate is a spring pressing against a diaphragm. Once the pressure of the air leaving the compressor exceeds the pressure of the spring, it moves the diaphragm, which is linked to a bypass valve before the exhaust turbine. The bypass opens, and some of the exhaust gas pressure is released into the exhaust (or, on some race vehicles, the atmosphere), mitigating boost.
An internal wastegate actuates a bypass valve located inside the turbocharger itself, while an external wastegate operates a bypass valve separate from the turbocharger. An internal wastegate system is more compact and requires less plumbing (most OE turbochargers use an internal wastegate), but is limited by the housing of the turbocharger. Most high performance and racing vehicles use an external wastegate system for its greater versatility.
Top Brands
When it comes to protecting your turbocharger and engine, you want a wastegate from a trusted manufacturer. That why Summit Racing Equipment only partners with proven brands like STS Turbo, Precision Turbo & Engine, Turbosmart, and VS Racing.

Turbosmart Gen-V HP Comp-Gate Wastegates
Turbosmart Gen-V HP (high-pressure) comp-gate external wastegates feature a new unique appearance, Gen-V architecture, more options, and more boost. Upgrades include their modularity, improved thermal management, water cooling options, and even more gate flow than ever before. Turbosmart answered the needs of the diesel tuning community years ago with their HP wastegate range. These Gen-V units take all the advances in design and entineering—such as water cooling, rotating housing, industry-leading gate flow, and 1/8 NPT reference ports—and pushes the results to new heights. The new Gen-V HP springs options alone mean as much as 50 psi of base spring pressure. Included in the box is the new Gen-V HP mechanical wastegate with 35 psi worth of pre-loaded springs (10 psi inner and 25 psi outer), all inlet and outlet weld flanges, valve seat and clamps, and basic reference port fittings needed to get set up and running. These wastegates are available in different external relief diameters.

Turbosmart StraightGate50 Pneumatic Wastegates
Turbosmart StraightGate50 vacuum wastegates are zero-offset butterfly-style units that allow enormous flow and almost linear control, and unparalleled boost control throughout the entire operating range. These high-flowing wastegates are simple to use, and packed with performance, flow, and features. The zero-offset butterfly valves are 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 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 pneumatic StraightGate 50s are available in a boost-based pSG50 6 psi or vacuum-based pSG50v 6 InHg versions. Both pneumatics take the electronic eSG50 version and simplify control via a traditional boost-based or vacuum-based actuator. Select the one you prefer. Key features: * 50mm (1.97 in.) butterfly-style zero-offset valve * 383.9 CFM/10.87m3 per minute flow * Stainless steel (630) butterfly and shaft * Stainless steel (347) main body * Stainless steel, heat-treated 431, V-band clamps * 6262 T-6 anodized aluminum bracket and actuator * Turbosmart unique locking collar ring * Base spring options from 6 psi to 42 psi * Suitable for single or twin port boost-based control * Stainless steel (N60) linkages and control arm

The Gen-V external line introduced modular architecture, allowing a rotatable diaphragm housing, optional water cooling, and the ability to swap actuator housings between gate sizes. These new models offer all the flow and interchangeability—with the kind of control never seen before, independent of any reference signal, without the need for compressed gas or boost lines. They're fully adjustable from your tuning interface; no need for changing springs. Boost control is completely adjustable from your laptop. As boost control strategies become more complex, Turbosmart engineers wanted a solution that maintains all the performance and reliability of the Gen-V range—and adds truly infinite control. These electrical wastegates operate on a current draw while providing fast and efficient boost control against up to 80 psi drive pressure (for the eWG60) and over 120 psi (for the eWG45). As with the Gen-V range, there is a provision for optional water cooling. Order the Gen-V model that best suits your performance needs.
