Power Stroke vs. Duramax vs. Cummins - Vegas Heat

Herbst Dyno Day

We love dyno events. Mostly, they involve standing around watching diesel trucks blow smoke and run up to more than 100 mph—yet go nowhere. And that’s fine with us. You see, a dyno measures power output, and that’s the name of the game as far as we’re concerned. Perhaps the best part about these types of competitions is the wild variety of vehicles that attend. Everything from brand-new trucks with tuners to race trucks to old, mechanically injected rigs can be seen on the rollers. If you’re curious about someone’s combination, there’s always plenty of time before or after the owner runs to ask questions. Everyone has their own theory regarding what works and what doesn’t, so it’s fun to hear the speculation before the moment of truth.
"For our first-ever event, it was an enormous success!
— Newly Tolf, Underground Diesel"
For all these reasons (and a little promotion for themselves), Underground Diesel teamed up with Terrible Herbst to host its first annual dyno day in Las Vegas, Nevada. Terrible had just installed a brand-new Mustang dyno in one of its carwash bays, meaning you can get fuel, an oil change, a wash—and see how much power your vehicle makes all in one trip. In order to really put Terrible’s dyno to work, Underground Diesel spearheaded an effort to bring a host of diesel trucks from its shop, along with inviting rigs from all over the Western region. And, despite 100-degree temperatures, there was a lot of enthusiasm as rubber met roller.

Dave Anderson
Hometown: Las Vegas, Nevada
Truck: 2005 Ford F-350
Engine: 6.0L Power Stroke V-8
Mods: S&B intake, Diamond Eye exhaust, Garrett Powermax turbo, Warren Diesel 195/75 injectors, ARP head studs, water-methanol injecton
Horsepower/Torque: 523 rwhp/878 rwtq
Notes: We were surprised by the numbers Dave’s 6.0L put down, considering it had a mild turbo upgrade. He wasn’t too surprised, though, as he’s run 13s in the quarter-mile in a heavy truck.

Nick Tobin
Hometown: Las Vegas, Nevada
Truck: 2008 Ford F-350
Engine: 6.4L Power Stroke V-8
Mods: H&S Mini Maxx, Flo-Pro exhaust, and S&B air filter
Horsepower/Torque: 545 rwhp/1,041 rwtq
Notes: Nick’s Ford is a good example of what 6.4L Power Strokes can put down with a healthy tune. Nick had a friendly rivalry with Anthony Arata, who has nearly the same setup and dyno’d later in the event.

Austin Ouellette
Hometown: Las Vegas, Nevada
Truck: 1997 Dodge Ram 2500
Engine: 5.9L Cummins I-6
Mods: #10 fuel plate, 5-inch exhaust
Horsepower/Torque: 257 rwhp/744 rwtq
Notes: Many people who buy ’94 to ’98 Dodges think there’s something wrong with their truck, because the Rams are so slow in stock form. With nothing more than a fuel plate and some big exhaust piping, Austin added another 100 rwhp to his second-generation ride.

Estey Gamboa
Hometown: Las Vegas, Nevada
Truck: 2004 Chevrolet 2500
Engine: 6.6L Duramax V-8
Mods: Custom intake, Underground Diesel EFILive, PPE Stage 4 transmission and lift pump
Horsepower/Torque: 463 rwhp/1,000 rwtq
Notes: Who says Duramaxes can’t make torque? Estey’s power curve impressed us, and when he gets a bigger turbo on there, we’d expect at least 50 more horsepower up top.

Dana Ferrarro
Hometown: Las Vegas, Nevada
Truck: 2000 Ford F-350
Engine: 7.3L Power Stroke V-8
Mods: Banks intercooler, Edge Evolution tuner, ATS transmission, Diesel Performance exhaust, AFE intake
Horsepower/Torque: 344 rwhp/751 rwtq
Notes: Dana’s 7.3L is a fine example of a truck that was built more than a decade ago yet has been lightly modified to keep pace with newer rigs. Its horsepower and torque numbers are nearly dead-on compared to any brand-new GM, Ford, or Ram.

Anthony Arata
Hometown: Las Vegas, Nevada
Truck: 2008 Ford F-350
Engine: 6.4L Power Stroke V-8
Mods: Spartan programmer, cold-air intercooler pipe, Flo-Pro exhaust, S&B air filter
Horsepower/Torque: 560 rwhp/1,021 rwtq
Notes: We were surprised to see how well the old-school Spartan tuner did on Anthony’s truck. It was clear the 6.4L Power Stroke was making great power (560 to 570 rwhp is usually about the limit we see on tuned 6.4L-powered trucks).

David Lee
Hometown: Las Vegas, Nevada
Truck: 2007 Dodge 3500
Engine: 6.7L Cummins I-6
Mods: H&S Mini Maxx
Horsepower/Torque: 422 rwhp/1,057 rwtq
Notes: David’s truck was virtually stone stock, other than an H&S programmer, which shows how much tuning can do. The Ram didn’t like 1,057 lb-ft of torque, and the transmission went into limp mode after the dyno pull.

Mike Wendell
Hometown: Beaumont, California
Truck: 2003 Chevrolet 2500
Engine: 6.6L Duramax V-8
Mods: PPE programmer and lift pump, Garrett GT4094, Inglewood Transmission Stage 5 trans
Horsepower/Torque: 518 rwhp/976 rwtq
Notes: Mike was just starting to get his new combination dialed in and later found out his fuel filter was clogged. With a new filter in place, power jumped to 570 rwhp.

Mitch Hanberg
Hometown: Vernal, Utah
Truck: 2004 GMC 2500
Engine: 6.6L Duramax V-8
Mods: 80mm S400 turbo, Industrial Injection 60-percent-over injectors, J&G transmission, head studs, EFILive, FASS lift pump, PPE up-pipes
Horsepower/Torque: 650 rwhp/1,088 rwtq (nitrous)
Notes: Mitch had barely done any tuning at all and wasn’t the happiest with his initial 543-rwhp pull, so a nitrous bottle was broken out and sprayed into the intake, resulting in an easy 100hp gain.

Brandon Wood
Hometown: El Mirage, Arizona
Truck: 2006 Dodge Ram 2500
Engine: 5.9L Cummins I-6
Mods: PPE dual CP3 kit, S&B intake, MBRP 5-inch exhaust, Mass Flow Engineering 100hp injectors, BD exhaust manifold, 64mm turbo, Sun Coast Converters transmission, EFILive, FASS 150-gph lift pump, AFE intake elbow, Turbosmart blowoff valve, TCS Suspension lift
Horsepower/Torque: 659 rwhp/1,334 rwtq
Notes: Brandon’s Dodge impressed the heck out of us with the power it was able to make with a little, 64mm turbo. It’s been in the 11s in the quarter-mile with nitrous. This is a truck anyone would be happy to own.

Tyler Richard
Hometown: Las Vegas, Nevada
Truck: 2006 Dodge Ram 3500
Engine: 5.9L Cummins I-6
Mods: Industrial Injection PhatShaft 66mm, 150hp injectors, Banks intake, 0.020-inch-over pistons, Hamilton cam, main and head studs, EFILive, MBRP exhaust, FASS fuel system, 85-percent-over CP3, Sun Coast Converters transmission, NX nitrous system
Horsepower: 695 rwhp
Notes: Breaking into the 600hp range on fuel and then hitting nearly 700 with nitrous, Tyler was piloting one of the harder-hitting Cummins-equipped trucks at the event—all with a single, 66mm turbo.

Colin Brazze
Hometown: Unknown
Truck: 2007 Dodge Ram 2500
Engine: 6.7L Cummins I-6
Mods: Dual CP3 pumps, 200hp Exergy Engineering injectors, FASS 260, Hellmann intake, H&S tuning, 75mm BatMoWheel turbocharger
Horsepower/Torque: 772 rwhp/1,111 rwtq
Notes: Colin’s big-turbo Dodge had a heck of a time spooling on the dyno, leading to an insane amount of smoke and a low torque figure. But boy, once it got rolling, did it make power—putting down 772 rwhp out of a single turbo.

Dan Grant
Hometown: Los Angeles, California
Truck: 2005 Chevrolet 2500
Engine: 6.6L Duramax V-8
Mods: 80mm Garrett GTX turbocharger; modified PPE Hot+2 E.T. Race programmer, up-pipes, and Dual Fueler; Socal Diesel heads and camshaft; ARP head and main studs; PPE Stage 5 transmission built by Inglewood Transmission; Mahle racing pistons; Exergy Engineering injectors
Horsepower: 930 rwhp
Notes: Since Dan grudge races his truck, he wouldn’t give us any specs on any internal engine parts of his high-hp build. But whatever the rest of his combination is, it sure works, as evidenced by the highest horsepower of the day—930 rwhp on fuel only!
