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

Testimonials

This guys are hands down the best turbo specialist in South Florida. Well worth the 2 hours drive. Got my Perkins Marine turbo Remanufactured and all I can say is wow. From a rust bucket to a brand new looking turbo in 3 days exactly. Just as promised, and the best part is I saved over $1k compared to the cheapest price I could find. They just got a life long customer.
If you are looking for a true turbo specialist, give these guys a call. Highly recommend them!
