From time to time, someone will ask us “Why does my car put out 290 horsepower on the dyno if it was rated at 300 horsepower stock?” Dyno results can be confusing for anyone who hasn’t read up on the topic. How can the same car put down different numbers just because the dyno manufacturer isn’t the same? These answers are simple much easier to understand if you know how a dyno calculates or measures horsepower and torque.
Grand Prize Winner: Ron’s 2009 Bullitt!
Wheel style & size: 18 x 9 and 18 x 10
Tire brand & size: NT555 255/45 & 285/40
Ron’s Mustang Bullitt has an impressive list of modifications. An Edelbrock E-Force Street-Legal Supercharger has bumped his dyno numbers up to 427RWHP and 396 RWTQ. With a Dynotech 3.5″ aluminum driveshaft, a BMR driveshaft loop and 4.10 Ford Racing gears, Ron’s making the most of all that horsepower. In order to help him harness all that power, the Bullitt now features a Steeda adjustable panhard rod, a CHE K-frame brace with Q-Limiters, BMR billet lower control arms, and Koni Yellow shocks and struts.
Ron hasn’t neglected his Bullitt’s appearance for the sake of performance, though. He’s added sequential tail lights and satin tail light trim, plus a chrome surround for the rear panel and a blackout panel. DG window louvers, smoked front turn signals with stealth bulbs, and SHR lower grille inserts round out his exterior mods. In terms of the interior, the ’09 features Autometer wideband air/fuel and boost gauges on an SOS double gauge pillar mount.
