OVER THE TOP
With the fuel system capable of supporting some serious power, it was time to turn to airflow. The factory turbocharger wasn’t going to hack it, so Mofford replaced it with a 69mm SX-E turbo from Borgwarner and added in a Stainless Diesel Performance intake and 5-inch Flo Pro exhaust. Tuning came in the form of a custom EFILIVE program by Starlite Diesel.
Making power is one thing, but getting it to the ground is another. Mofford wanted to make sure he was able to use the power he had, and the factory Allison stood little chance of survival behind the modified Duramax, especially because the truck was putting its 700 horses through 42-inch tires. There was no doubt about it; the transmission needed an upgrade. It was Mofford’s neighbor down the road, Dimitri Millard at No Zone Diesel, who came to the rescue. No Zone strengthened the Allison in a number of areas internally and was also able to select a converter combination that would work well with the elevated ride height and tall tires.
After nearly a year of planning and hard work, Nick Mofford was ready to hit the road in his unique show truck. Because of the truck’s upgraded engine that makes a lot more power than an average show truck, as well as larger wheels and tires and even a powdercoated frame, Mofford might have gone a little far with his newest build.
But isn’t that what hot-rodding is all about?
