WARNING: Maximum allowable turbocharger speed is 102.5krpm. The use of this product above max turbocharger speed is at the owner’s risk, and can result in damage and premature failure. To protect the turbocharger from overspeed when operating, a speed sensor can be installed into the compressor housing to monitor shaft speed. Sensors sold separately. (click here for details)

Performance results of this product are highly dependent upon your vehicle’s modifications and tuning/calibration. The horsepower numbers represented above are calculated based strictly on choke flow of the compressor map (total turbo capability), which represents the potential flywheel horsepower.

                                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
