                            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
