RPG Installs A Phase 2 ROUSHcharger Kit

Forcing The Issue

To say that Roush has a lot of cache in performance and racing circles is a huge understatement. Jack and his trademark hat have more race wins than most teams have race entries. So when we heard the RPG guys were going to be installing a Phase 2 ROUSHcharger to a 5.0 engine-equipped truck, we wanted to watch the process.

We are fans of superchargers, and have a great deal of respect for Jack Roush and his accomplishments and the company that he’s built. So, we wanted to take a look at the system.

The heart of the system is the R2300 Supercharger. Delivering 8 pounds of boost increase, the R2300 Supercharger features what Roush calls TVS Technology, and they say that the Twin Vortices Series has four-lobe rotors with greatly enhanced thermal efficiency, thus enabling greater volumetric capacity at higher rpm. Cooling is done with a large aluminum intercooler intake manifold along with a low-temperature radiator with a nicely molded air duct and a high-capacity degas bottle.

To keep the R2300 filled with air and to take full advantage of that life-giving boost, other tricks include Roush-designed high-flow fuel injectors, a Roush 60mm dual-bore throttle body and an all-new, high-capacity, low-restriction air filter and complete induction system. Tuning is done with the all-important Roush Phase 2 calibration file that’s delivered with the exclusive Roush Diagnostic Tool (RDT).

And maybe the best part is that the Roush Phase 2 ROUSHcharger system is 50-state emission legal, according to the 2015-2016/CARB E.O.#D-418-27.

For $7,500 plus install, and you probably do want to have it installed, the Roush system is a great way to increase horsepower. Like every supercharger install we’ve ever seen, installing one is a hugely complicated process and this system is no different, but the results are always worth it. We want to thank the crew at RPG Offroad in Laguna Hills, California, for letting us shoot over their shoulders while they went about their business.
