                              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
