“We’d make a change, and then go to the track on Friday night,” he told us. What he didn’t plan on was the truck running low eights almost immediately, followed by high sevens within the first year of ownership. The fogger system helped the truck gain more than 100hp on the chassis dyno, and Steven says it is calculated and sized to support a 250hp hit.īought for just $700, Steven’s initial goal for the truck was to put together an E.T. But Steven’s nitrous system goes beyond that, as he engineered and built his own fogger system within the intake plenums, to get as close as possible to individually feeding each cylinder a solid dose of N2O. A Nitrous Express Lightning 250 system adds another 180hp into the mix. To curb this, Steven routes fuel through a Derale electric auxiliary cooler that he remote-mounted to a cross member in the bed. With just six gallons of fuel onboard, diesel heats up fast and can rob horsepower. The Walbro pump pulls fuel from a six-gallon, stainless-steel fuel cell that Steven fabricated himself. Steven built his own electric fuel-supply system around the Walbro unit, which incorporates a pre-filter, fuel filter and a Fuelab regulator, set at 67psi. Another readily available yet proven component that made its way onto the truck is the Walbro GS元92 lift pump. Absorbing nitrous blasts and seeing 70 to 75psi of boost on each pass, the non-waste-gated turbo has been extremely durable.

The corresponding intercooler pipes, intake plenums and up-pipes also came from Irate, while the plastic intercooler was sourced from a 6.0L Power Stroke. The proven BorgWarner S467.7 FMW turbo feeds the engine and mounts in the lifter valley, thanks to a T4 turbo mount from Irate Diesel Performance. Dyno Proven also handles the PCM tuning, and Steven navigates tunes via an F8 chip from DP-Tuner. high-pressure oil pump from Dyno Proven maintains the oil volume they require.

For fuel, a set of 300/200 hybrid injectors from Full Force Diesel sit above each cylinder, while a Honey Badger Sr.

Its only hard-part upgrades consist of beehive valve springs from Dyno Proven, Smith Brothers Chromoly pushrods and ARP head studs, which were threaded in one at a time. A 367,000-mile forged-rod, stock-bottom end 7.3L Power Stroke is the foundation of Steven Davis’ lightning-quick F-350.
