GOIN’ FOR BROKE
to lose. His Heui-injected, stock-bottom-end 7.3L is up against a sea of built-to-the-hilt Cummins and Duramax mills, many of which are cranking out 400 more horsepower. The fact that his Ford can hold its own against some of the strongest running trucks in the Southeast says a lot about its overall setup and his driving experience. With more than 130 hooks on a junkyard 7.3L that regularly sees 4,200 rpm and nearly 60 psi of boost, it’s easy to see why the weight box says Goin’ for Broke.
Keeping a stock-rod 7.3L Power Stroke alive at 600 hp means limiting low-rpm timing and making sure the engine lives upstairs. To do this, Green called upon Power Hungry Performance for custom PCM tuning via one of the company’s Hydra Chips. The custom-tailored file Green pulls with waits until roughly 2,600 rpm before aggressively ramping up timing, and also calls for 3.2 milliseconds of pulse width and 3,500 psi of injection control pressure (ICP).
This shift box, built by Irate Diesel Performance’s Matt Maier, allows Green to have full control over converter lockup. During the course of a pull, Green leaves the 4R100 in third gear, locks the converter at 4,200 rpm, and doesn’t unlock it until the truck spins out at the end of the track.
