Garrett Vent External Wastegates regulate turbocharger shaft speed by venting exhaust gas around the turbine stage of the turbocharger. CFD optimized design maximizes flow and delivers optimum boost control. Advanced thermal optimization increases durability of the diaphragm. The cap design makes spring changes and serviceability of the entire GVW lineup easier and more reliable to perform.
Features
Flow Data
Garrett engineers created GVW as a high flowing product with low degradation in performance over its lifespan. Here’s how the three GVW wastegate sizes flow in LBS/MIN and KG/SEC at various increments of the valve stroke.
Material Data
The valve housing is cast from high temp stainless steel and rated for exhaust temperatures up to 1050° C. CFD optimized for maximum flow and thermal efficiency.
Mechanical Data
Garrett Vent | External Wastegates are created by the engineers that designed G-Series and GTX Gen II turbochargers. Size: 45mm
Thermal Data
When researching and testing common shortfalls of wastegates, we observed how heat cycling and normal wear can rapidly change their actuation characteristics. Garrett engineers created GVW as a high flowing product with low degradation in performance over its lifespan. Actuation data (opening and closing) in the chart was measured before and after extreme testing conditions. Results show the heat cycled GVW product maintains linear control of the wastegate as compared to the new product. Precise actuation of the GVW provides accurate calibration settings and performance throughout the lifespan of the product. Accurate wastegates, allow for optimum performance of the turbocharger.
Kit Contents
GVW Wastegates include all the following parts:
Wastegate Springs
GVW wastegates are set to 1 Bar / 14.5 PSI of base pressure and can be configured from 0.2 Bar / 2.9 PSI – 1.6 Bar / 23 PSI (considering 1:1 backpressure).

GVW Wastegate Placement Suggestions
Wastegate placement on the exhaust manifold is a key factor in wastegate performance. The following suggestions can help identify the best choice when purchasing or fabricating an exhaust manifold for your project. The connection on the manifold greatly affects flow capability, and correct orientation of the wastegate to the manifold is essential.
The ideal connection is at 45° with a smooth transition (Figure 1). Placing the wastegate at 90° to the manifold (Figure 2) will reduce flow capacity by up to 50 percent and can cause over boosting! More reduction in flow capacity will result if the wastegate is placed at angles greater than 90° (Figure3). Figures 2 and 3 greatly reduce the control you have over the system and can put your entire drive train at risk. Never mount the wastegate to the turbine housing at any time, this will reduce the performance of the turbocharger (Figure 4). Contact an authorized distributor for additional information.
Wastegate Port Fittings
GVW wastegates feature a water-cooling circuit which allows the product to be operated in extremely high temperature conditions while maintaining its actuation characteristics. Water-cooling symbols are etched near both of the fitting ports for easy identification. If watercooling, both ports must be used to create a coolant loop. (2) Water fittings and (2) washers are included and can be installed with a 14mm wrench or socket.
There are two air ports on the top cap and three air ports on the valve body. (2) 14mm Banjo fittings with washers and (3) 5mm hex head air plugs are included.
