Garrett - GTX5009R GEN II Turbocharger

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 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
