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.

Valve Housing: High temp stainless steel rated up to 1050° C
Diaphragm: High temp Nomex reinforced elastomer
Actuator Cover: Fully-machined anodized 6061 aluminum
Valve Guide | Bushing: Nitronic 60
Valve: high temp stainless steel with plated stem
V-Band: CNC machined 304 stainless steel
Flanges: Fully-machined 304 stainless steel
Springs: 17/7 PH stainless steel

Garrett Vent | GVW-50 50mm Blue Wastegate

MECHANICAL DATA

Garrett Vent | External Wastegates are created by the engineers that designed G-Series and GTX Gen II turbochargers. Available in three sizes: 40mm | 45mm | 50mm

Valve Diameter: 40mm | 45mm | 50mm
Valve Mass: (40mm)1.27kg | 45oz (45mm) 1.47kg | 52oz (50mm) 1.56kg | 55oz
Max Spring Base Pressure: 1.7 bar | 25 psi (1:1 backpressure ratio)
Minimum Spring Base Pressure: 0.2 bar | 3 psi (1:1 backpressure ratio)
Port Fitting | Air: M10x1.0 to hose barb (hose ID 6mm | .25in)
Port Fitting | Water: M8x1.0 to AN-3

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.

Max Thermal Stress (non-cooled): 270°C actuator body temp during thermal cycle test
Max Thermal Stress (liquid-cooled): 130°C actuator body temp during thermal cycle test
Max Exhaust Temp | Peak: Up to 1050°C

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.
Please see the boost control section for more information on how to install the port fittings based on your application.
