DINOSAURS AREN’T EXTINCT

perfectly with each other, and make a significant difference in the 7.3L’s power output. Another high-horsepower 7.3L addition is a Meziere electric water pump, along with a water pump adapter plate from Gray’s Diesel Performance.

TWO HPOP’S, BIG HYBRIDS, AND ALL THE FUEL SUPPLY

If you’re building a 7.3L to compete against a sea of 1,500hp Cumminspowered trucks, you start with the biggest injectors Unlimited Diesel Performance makes, a set of its 455/400 hybrids. The high-flow injectors are capable of moving 455cc’s worth of fuel through 400-percent over nozzles, and they’re supported on the oil side thanks to a Swamps Gen3 high-pressure oil pump mounted over a stock, 17-degree Super Duty HPOP. Brian’s fuel supply system revolves around the use of an Aeromotive A1000, complete with a regulated return and a -6 AN fuel line feeding the back of each cylinder head.

RACE-READY S480, CUSTOM EXHAUST MANIFOLDS, AND A LITTLE NITROUS

As one of the pioneers for highhorsepower, big single turbo 7.3L’s,

Brian has run more than his fair share of Borgwarner S400’s over the years, so he knows what works. Currently, an S480 from KC Turbos crams as much as 70-psi of boost through the truck’s On3 Performance intercooler. The 80/96/1.32

With gobs of fuel and a bit of nitrous in the mix, an external wastegate is always a good idea—and two is even better. Although Brian tells us he hasn’t sprayed the engine enough to worry about over-speeding the turbo yet, his 46mm Precision wastegates will come in handy when he decides to push deeper into the 5’s. For now, the turbo produces a relatively safe 70-psi of boost on a typical 5.90 pass. Big injectors require big fuel supply, and Brian didn’t skimp in that department. Massive, -10 AN hose feeds an Aeromotive A1000 from the rear-mounted, 5-gallon Summit Racing fuel cell. From there, -8 AN line carries fuel to a Y-block, where fuel supply splits into two -6 AN hoses to feed the back of each cylinder head. Pressure on the adjustable Fuelab regulator is set to 65 psi. The bottle is always full, but Brian maintains he isn’t using much nitrous to run consistent 5.90s. In fact, he’s only using a .070 jet and a .030 spool jet in his mild two-stage system at the present time. Brian uses Nitrous Express Lightning .125 solenoids and brings N20 into the cold-side intercooler pipe. The spool stage is manually triggered on the steering wheel during staging.
