As a full-time firefighter and EMT for Anne Arundel County, Corsilli stays busy working overtime putting out fires and saving lives; but during his time off, he enjoys wrenching on and racing this 2009 6.4L Power Stroke dubbed “Murica,” which has not only turned out multiple, low-11-second quarter-mile times, but was the first single-turbo 6.4L Power Stroke to crack that 1,000hp fuel-only milestone. “Michael Corsilli built this 2009 Ford for two reasons. One, to go fast. Two, to go even faster”Subscribe Our Weekly Newsletter Modest Intentions After first purchasing the Ford new in late 2008, Corsilli vowed that this one was going to stay relatively stock, with maybe just some performance tuning and a better exhaust. Unfortunately, when you’re best friends with Craig Briggs, owner of Maryland Performance Diesel (MPD), and just an hour away from Innovative Diesel, where owner Eric Eldrith has specialized in Power Stroke tuning for more than 10 years, that’s a promise nearly impossible to keep. While the truck was making close to 600hp with mild bolt-ons, it soon grew “boring” and a single-stage NX nitrous kit was added to push power levels a bit further. After a few engine troubles on the sled pull track, the cab was raised so the engine could be repaired and upgraded with ARP head studs. Still running stock turbos, this setup was good for an 11.60@118 mph at the track but eventually, this setup finally started taking its toll on the stock transmission. At this point, Corsilli was hooked on drag racing and there was no turning back. Again, he turned to MPD for help; the factory 5R110 transmission was pulled and worked over with upgraded clutches and billet shafts. The factory torque converter was replaced by a triple-disc billet unit from Diesel Performance Converters of McDonough, Georgia. With a transmission that could finally hold some power, Corsilli jumped into things a bit further: he helped MPD test and develop a single turbo conversion kit to get rid of the factory VGT compound system in favor of an S472. Still running stock injectors, this combo was a bit laggy for daily driving needs, but managed to put down 947hp with nitrous on the dyno and run an 11.35@122 mph at the track. All In After driving the truck in this form for a few months, MPD fabricated a more conventional compound turbo kit for the truck that fitted a Borg Warner S483 in the fender well to help feed the S472. To go along with all that air, additional fuel was added with some 60 percent over injector nozzles from Maryland Fuel Injection; an Industrial Injection Dragon Fire injection pump and Aeromotive A-1000 lift pump were added to help maintain rail pressure under hard load. This combo made dozens of fuel-only mid-11-second passes; however, after 60,000 miles, the factory pistons and pushrods finally decided enough was enough and led Corsilli to start a complete engine rebuild from the crank up. “It’s the first single-turbo 6.4L Power Stroke to crack that 1000hp fuel-only milestone” The new engine was fully balanced and blueprinted by MPD and included .020+ Ford pistons machined with de-lipped bowls and deeper valve reliefs. The camshaft was upgraded to Colt Cams Stage 2 to increase lift and duration for better power at higher rpm. Cylinder heads were left basically stock, but upgraded with River City Diesel pushrods and valve springs. Along with the internal upgrades, the injectors were also honed out further to 100 percent over and matched up to a Dual Fueler injection pump kit from River City Diesel. The compound turbos were removed and a billet 76mm S400 with 92mm turbine wheel and 1.10 A/R T4 was ran again on the MPD single-turbo kit. After some time on the chassis dyno at Innovative Diesel, after dialing in the fueling and tuning via the SCT Livewire tuner, the truck has bested all previous times at the track with an 11.05 e.t. on fuel only. The new powerplant also lit up the dyno room as the first single-turbo 6.4L Power Stroke to break 1000hp, with a 1,016hp and 1,599 lb-ft of torque dyno chart to prove it. Under the hood you’ll find plenty of aftermarket parts helping that 6.4L Power Stroke put down more than 1,000hp on fuel only. The MPD billet crankcase breather re-route kit, River City Diesel Duel Fueler Kit, and Forced Inductions 76mm ETR turbo are key parts to the truck’s build. The polished 76mm turbocharger is mounted under the hood using a Maryland Performance Diesel single-turbo conversion kit. Not wanting to be limited on power by sticking with factory-style VGT compounds, the big S400 turbocharger moves more than enough air to support low-11-second quarter-mile times in a nearly 8,000-lb truck. The interior of the truck has been kept pretty simple; beside the hydro-dipped digi-camo panels from Baltimore Hydrographics, you’ll find a DashDaq monitor for watching engine vitals, a couple 0-100psi gauges to watch boost and drive pressures, and a handheld nitrous switch for when the need arises. Putting all of that horsepower to the ground is a set of 305/50R20 Nitto 420 tires wrapped around two-piece 20×12 Fuel Maverick wheels. The truck also rides on a set of Rancho shocks and custom-fabricated rear traction bars built by MPD. Lookin’ Good Since you can’t have a stock-looking 1,000-hp truck, the chassis and body have also undergone multiple upgrades. The factory suspension has been lowered by removing the rear blocks and replacing the front coil springs with shorter, 4,400-lb coils from Ford. Shock absorbers have been upgraded to Rancho RS9000, which allow some suspension adjustment for both street and drag use. For tires, the slightly lowered Ford sits on 305/50R20 Nitto 420 tires wrapped around Fuel Maverick two-piece 20×12 wheels. The bumpers and grille were painted to match that factory deep blue metallic paint to really set the truck apart. The factory fender vents were then removed and hydro-dipped in a blue/grey digi camo by Baltimore Hydrographics. The 7-inch single-exhaust stack and MPD traction bars were coated by DB Powder Coating to keep its appearance nice and clean. Don’t forget that custom “Murica” Maryland license plate. With more than 1,000 rear wheel horsepower and plenty of street-driven miles, you can be sure those Nitto 420 tires don’t last nearly as long as they should, thanks to a heavy right foot. The most recent dyno session showed the 6.4L Power Stroke was producing 1,016hp and 1599 lb-ft of torque. Those kind of numbers not only make it the first single-turbo 6.4L Power Stroke to crack 1,000hp, but puts it in an elite group of 1,000-plus horsepower Cummins and Duramax trucks, as well. Interior Mods On the inside, Corsilli had most of the removable door panel and dash pieces hydro-dipped in blue Digi camo as well. For gauges, just a pyrometer and two 100-psi gauges for watching boost and drive pressure are needed. Future plans for the truck consist of upgrading the cylinder heads to some fully ported units along with a ported intake manifold in hopes of reaching 1,100hp, fuel only. Corsilli would love to see some fuel-only, 10-second quarter-mile times from the truck this season and is ready to take this Ford to the front. For those Cummins and Duramax boys that don’t think a Power Stroke can keep up, keep your eyes out for this one, you’re going to be surprised. DW The F250 runs a host of aftermarket pieces engineered and produced by Maryland Performance Diesel of Baltimore, Md. Hiding behind the bumper is the remote oil cooler that helps keep that fully built MPD engine running cool, even under heavy abuse at the track. Total 0 Shares Share 0 Tweet 0 Pin it 0 Share 0
