In the hyper-competitive world of aftermarket horsepower building, itâ€™s all about the numbers. To show off the capabilities of its supercharger systems, Roush Performance recently released a video of a tuned-up Phase 1-supercharged 2015 Mustang, and the results were downright impressive.
â€œOur development team has been busy at work finalizing our Phase 2 and Phase 3 kits for the 2015 Mustang,â€ the company said of its video. â€œAttached is a recent dyno run for a development vehicle showing rear wheel horsepower with a stock engine and our phase 1 Supercharger kit hardware plus the following upgrades: 75mm supercharger pulley, upgraded fuel injectors, revised version of our 2011-2014 fuel pump booster kit, and minor calibration enhancements.
The car made three back-to-back pulls over 700 rear-wheel horsepower, with the best pull approaching 750 at the feet! Check out the dyno runs hereâ€¦
â€œTesting was done using 93 octane, stock manifolds, and stock catalytic converters,â€ the company added. â€œAs you can see, with some small modification to our Phase 1 hardware, our 2.3-liter supercharger kit is more than capable of making in excess of 800 horsepower at the crank. Stay tuned for more on our Phase 2 and Phase 3 kits coming soon!â€
We are certainly excited to see how much more power they can wring out of this system with the upper-level Phase kits!
