Key Product Specs
  • Roush's Stage 2 Supercharger Kit blows the roof off the Stage 1 kit, it's calibrated to give your noble steed 625 horsepower and 525 ft/lb of mind blowing torque! Let's put that in perspective, that's 205 HP and 135 ft/lb of torque over the stock Mustang. This supercharger features Eaton's new TVS (Twin Vortices Series) technology rotating assembly that delivers more horsepower and torque, better fuel economy and superior performance in a small package. We can't emphasize this enough, Roush truly has raised the bar with this one.

  • Roush's R2300 TVS supercharger is a roots-type, positive displacement supercharger that features twin four-lobe rotors that are twisted 160-degrees. Compare that to Eaton's original supercharger rotating assembly which was only rotated 60 degrees. The fourth lobe and added twist, when combined with newly redesigned air inlet and outlet ports, greatly enhance thermal efficiency, deliver higher volumetric capacity, enable higher operating speeds, creates a smoother, more efficient flow of air into the engine and has improved noise and vibration characteristics.

  • Unlike turbochargers, superchargers are belt driven which means instant power at your disposal throughout the entire powerband. The entire kit includes the R2300 2.3L TVS supercharger, an 85mm supercharger pulley, fuel charging assembly with Roush designed upper and lower aluminum intake manifolds, twin 60mm throttle body and matching throttle body spacer, a cold air induction system with 110mm MAF, washable/re-usable open element air filter and air dam, a high flow fuel rail with 47lb injectors, a high efficiency intercooler system featuring large full face low temp radiator, oversized coolant degas bottle, high capacity air-to-water intercooler and formed hoses with abrasion-resistant sleeves, Roush's flash voucher card as well as all of the required fasteners, wiring, brackets, hoses and clamps. Although that was a mouthful, you can be sure you're getting everything you need to take your Mustang to the next level. This kit utilizes the Roush Flash Voucher card to be calibrated using ROUSH Diagnostic Tool (RDT) software and pass-thru device. If you do not have access to an approved pass-thru device, you can send your PCM back to Roush to be flashed.
