The ROUSHcharger (pictured) is officially rated to increase the Mustang's 4.6L V8 to 510hpr and 510lb-ft of torque (380kW and 691Nm), but as mentioned above this unit is designed to be tuned to improve performance even further. The TVS2300 ROUSHcharger features Eaton’s new Twin Vortices Series technology, utilizing a four-lobe rotor and high-flow inlet that greatly enhances thermal efficiency, allowing higher volume capacity and higher operational speeds in order to boost engine performance.
Included in the package is the complete TVS2300 ROUSHcharger system featuring new upper and lower intake manifolds for the high capacity air-to-water intercooler and larger TVS supercharger. A custom ROUSH calibration is included, as well as new fuel rails and high-flow 52lb fuel injectors, a high-flow capacity fuel pump, and a dual electronic throttle body. A Roush Cold Air Kit with a carbon fiber clean air tube rounds out the package.
The whole kit is priced at $5,899 but if you already own a Roush supercharger package several components of that can be re-used to lower the asking price to $4,999.
