This 2015 Roush stage 2 is one of our shop test vehicles that made an astounding 850 rwhp on the stock engine. How did we get there? With a Vortech JT supercharger that peaks at about 16 psi, this setup has surpassed even our expectations. The Vortech JT is the upgraded head unit from Vortech for more boost and bigger power gains. We added a GT350 intake, an 8-rib swap to prevent belt slip, the air-to-air intercooler, and all plumbing to easily install this kit. We added some ID1000 injectors and a fuel pump booster to handle the fuel requirements, along with over 80 hours invested in custom tuning on our in-house dyno and the street to get the perfect blend of drivability and performance together. We are an authorized Vortech dealer, so give us a call to order this package for your S550.

Our latest development has been to create a “Cammed Idle” calibration for this car using the variable cam technology to adjust the cam overlap. This creates the awesome sound of aftermarket camshafts without the expensive upgrade to new cams. We’ve spent hundreds of hours perfecting the Cammed Idle tune to put our flare on the way we think the car should act and sound.
