Gen II Compressor Wheel Dimensions and Aerodynamics

 

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

 

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 
  • +10mm longer on the comp inlet 
  • 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
