Description
GTX4720R GEN II Turbocharger
About Garrett? GTX Series Turbochargers
Garrett? GTX Series turbochargers are designed specifically for the hard-core enthusiast who wants optimal performance. The forged fully-machined billet aluminum compressor wheels feature next generation aerodynamics that provide a larger horsepower range and maximize boost response.
Ported shroud compressor housings increase surge resistance and provide reliable, continuous power throughout the power band. A dual ceramic ball bearing cartridge prolongs the lifespan and improves shaft balance. The water cooled CHRA keeps housing temperatures to a minimum. The turbine wheel is constructed from Inconel, a Super Alloy that maintains strength during prolonged exposure to high exhaust gas temperatures.
Turbine kits are offered in open volute and twin scroll, and a variety of A/R and flange configurations. GTX Series turbochargers are used by today?s top motorsports teams and are ready to boost you to the podium or wherever your destination may be.

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
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
