Wastegate – New V Series, 5th Generation Wastegates at SEMA 2017

Turbosmart Press Release

Turbosmart 5 series wastegate range

2017 sees Turbosmart introduce its 5th generation wastegate range and a brand new member to the Kompact BOV family as the team kick off SEMA 2017.


Based on 20 years of continual development in our products. For 2017 we have revised every aspect of our wastegates, analysing over 700 simulations performing fatigue testing at over 1 million cycles, all to provide our customers with the best performing wastegate currently available.

Our new wastegates are a direct fit upgrade to all 4th-generation Turbosmart wastegates and feature our unique collar-locking system, completely variable actuator cap and base, strap-type V-band clamps, liquid-cooling, 1/8″ NPT ports, and are provided with a range of springs. They are also available in Motorsport and Gas-only versions for those requiring specific applications.

Turbosmart 5 series wastegate modular design


The 5th series wastegate range has been designed for maximum user-adjustability, without compromising performance. We designed our new unit to allow actuators to be interchangeable across the range. So, if you need a large wastegate in a tight space you can run a smaller actuator on the larger body. Additionally, if you decide to upgrade your new wastegate to a Motorsport or Gas-only actuator you can with an upgrade kit!


The unique variable adjustment design allows the wastegate actuator base to be oriented independently from the weld flanges. The cap is also completely independent and indexable in 12 different positions compared to the actuator base and body. This allows the wastegate to be fitted in confined positions without compromising packaging for fittings or aligning the cap.




Upgrades and Servicing

Due to the modular construction, the new range is also upgradeable and completely serviceable, as all components can be removed or upgraded. Components have been tested for over one million cycles so reliability will be rock-solid.

Turbosmart V series wastegate Thermal flow

Flow and Thermal Performance

Our new range of wastegates out-flow all competitors thanks to our world-leading engineering and simulation abilities by conditioning the flow path around the valves. Thermal performance has been improved drastically compared to our nearest rival, and all wastegates feature liquid cooling ports for further thermal performance if required

Turbosmart V series wastegate Breakdown


Turbosmart’s wastegate range features the same spring increasing in rate at 2psi increments, up to 32psi. The uniform spring rate allows for easy closed loop PID boost control scaling and complex maths integration. Our diaphragm design offers linear travel, regardless of spring, pressure and valve position, while improving response. For fine-tuning, boost performance, a selection of springs will be supplied with each wastegate. All wastegates a feature 1/8″ NPT ports for maximum response and flow while maintaining a high level of compatibility for fittings.
