Earlier this week, we told you about the 2015 Roush Stage 3 Mustang and how it would be making over 630hp and while we were impressed by the feat, we now know exactly how much power this fire breathing pony will make. How does 670hp and 545 lb-ft of torque sound? Pretty freaking rad in our opinion!

The 2015 Roush Stage 3 Mustang features Roush’s latest 2.3L TVS supercharger which helps kick the 5.0L Coyote scream all the way to 670hp. That’s 240hp above the stock 430hp that the 5.0L Coyote pumps out. What’s even more impressive is that this is just the first phase of their calibration. Roush is expecting to make more power in their phase 2 and 3 calibrations so you can expect those numbers to go up.

The 2015 Roush Stage 3 Mustang is backed up by a 3-year/36,000-mile warranty so you know Roush is serious about making astronomical power levels reliably. All we can say is we’re pretty darn impressed with just how much power the Roush Stage 3 makes and can’t wait to shred some tires with this beast!
