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.

  • 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

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
