Dyno is calibrated and ready to roll!

Mustang engineers came out to Quantum Performance this week and have finished calibration of our machine! Our Dyne is fully functional and ready to roll. The accuracy is top notch; with our first car following calibration putting down consistent numbers with each pull. In fact, back to back power runs produced the exact same numbers on the same vehicle! And, the machine has proven itself to be very safe and easy to operate. No ramps or risk of falling off like above ground machines, multiple rollers create less risk of driving off a roller, and easy on/off for lower vehicles. We are very excited to have one of the best dynes in the world, in our very own shop! Check out the website GALLERY for more pics of the machine and the install, and look for some videos to come!
