Gen II Compressor Wheel Dimensions and Aerodynamics

GTX4709R GTX5009R Available in 76mm and 80mm inducer diameters

  • Comp exducer is now 109mm (+1mm vs Gen I)
  • Gen II wheel produces 15% more air flow
  • 39% lower inertia

GTX4720R GTX5020R Available in 76mm, 80mm, and 88mm inducer diameters

  • Comp exducer is now 120mm (+2mm vs Gen 1)
  • Gen II wheel produces 9% more air flow
  • 30% lower inertia
  • Reduced inertia due to reduction of material in the hub and blades
  • Roughly 20% lower mass
  • Lower inertia helps make boost faster and increases overall turbo efficiency
  • Increased flow has potential to make more power at same boost or same power at lower boost levels

Larger Comp Exducer on Gen II

.88 A/R Compressor Housing

Gen II features a larger .88 A/R (Gen I .69 A/R)

  • This helps maximize the power capacity of the new compressor wheel.
  • This is also the same compressor housing used on the GTX5533R (85mm and 88mm)

Larger Compressor Volute

.88 A/R Compressor Housing

Gen II features a larger .88 A/R compressor housing that will cause an increase in outline dimensions only on the cold side of the turbo.

  • +6mm longer on the comp outlet Fig. A
  • +10mm longer on the comp inlet Fig. B
  • Comp outlet diameter 107mm (same)
  • Not outline interchangeable with gen 1

Additional Features

  • Lightweight billet backplate
  • (NEW) Backplate to compressor housing O-ring
  • Speed sensor port compatible only with new flange style speed sensors: (pn 781328-0003 Street Kit | pn 781328-0004 Pro)

Compatible only with New G Series Speed Sensor

About Garrett® GTX Series Turbochargers

Garrett® GTX Series turbochargers are designed specifically for the hard-core enthusiast who wants optimal performance. The forged fully-machined billet aluminum compressor wheels feature next generation aerodynamics that provide a larger horsepower range and maximize boost response.

Ported shroud compressor housings increase surge resistance and provide reliable, continuous power throughout the power band. A dual ceramic ball bearing cartridge prolongs the lifespan and improves shaft balance. The water cooled CHRA keeps housing temperatures to a minimum. The turbine wheel is constructed from Inconel, a Super Alloy that maintains strength during prolonged exposure to high exhaust gas temperatures.

Turbine kits are offered in open volute and twin scroll, and a variety of A/R and flange configurations. GTX Series turbochargers are used by today’s top motorsports teams and are ready to boost you to the podium or wherever your destination may be.
