RESULTS:

The moment of truth for our 600hp build arrived when we strapped the truck to the chassis dyno. After producing 502-rwhp on fuel, we made sure ample bottle pressure was on tap, armed the NX system, and made a pass on spray.

Thanks to the nitrous and with a 0.078 jet installed, we picked up 94 hp at the wheels and squeezed 596 hp out of the 16 year old 7.3L. As you can see the nitrous cleaned up the smoke almost completely, so we’re sure that with some tuning for more fuel and a step up in the nozzle size, we’ll be able to get every last drop of NX’S 150 hp rating with numbers closer to 650 hp. With adequate traction at the track our near-600hp Super Duty should be capable of running a mid-12 in the quarter-mile.
