The 2015 Mustang provides a great platform to build off of. With the engines ability to handle great amounts of power, it was a no brainer to go with a Supercharger. There's a lot of superchargers in the business but we chose to go with Whipple. Whipple offers a reliable product that is made of high grade material and runs into zero fitment issues. The Kit is made to slap onto factory applications and includes everything you need for the installation eliminating the hassle of hunting down part by part. The horsepower and torque gains are exceptional over stock even with factory manifolds and exhaust! We went with the Stage 2 Kit and received 230hp gains over stock! This was enough power for our client for now, however with the installation of Long Tube headers and a cat-back exhaust system, we can push out horse power numbers in the range of 670hp!
