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
