The Aurora 4000 is an upgraded turbo charger that is great for added performance on your 2003-2007 Dodge 5.9L Cummins. The 63mm inducer compressor wheel on the turbo is a significant jump in performance over the stock charger. This turbo has the capability to reach 600hp with supporting fuel modifications and higher tuning levels with the ability to run 40 and up psi. The increased air volume will utilize all fuel injected into the cylinder creating a more complete and efficient combustion event.
This will result in lower EGTs, high horsepower capabilities, and a more efficient/powerful torque curve. The billet compressor wheel is one of the strongest on the market, and has the ability to run higher pressure ratios without fin deflection or fatigue. It is also capable of being spun harder and faster and keep its form even after thousands of heat cycles.
