Dyno Day 2020: We Had Minimal Carnage And Sizable Power

It’s time for a dyno shootout, and thanks to our friends at Greg’s Tuning Operation in Sikeston, Missouri, we have his brand new DynoJet dyno ready to rock and roll for every truck in attendance.

We have a very wide range of trucks here when it comes to power and torque. On one end of the spectrum, we have a virtually bone-stock Ford F-250, with a 7.3-liter Power Stroke engine. On the other end, we have a fire breathing Cummins with a bed full of nitrous ready to go. This works great because it offers a wide variety of results for different trucks and configurations

Landon Hinkebein brought his 1997 Ford F-250 7.3-Liter Power Stroke with a stock turbo

Landon’s truck has the benefit of an S&B Cold Air Intake, 4-inch exhaust, Full Force Diesel Performance 238/100 fuel injectors, Swamps Diesel high-volt, high-frequency IDM, and a JeliBuilt-tuned Hydra chip. This was the first time for Landon on a dyno and he sunk some money into this truck hoping to get it to perform better than OE. With a good set of injectors, custom tuning, and exhaust, he should be on his way. Only time will tell whether or not this all paid off.

Landon was struggling to load the truck as needed and it didn’t make the power he wanted. As he was unloading the truck off the dyno, he realized that he left the emergency brake on while dynoing. So, pro-tip, always check your emergency brake. Sorry, Luke.

“Next time, I want to hit the dyno with a lockup controller and try it without the emergency brake on. This way, I can control what gear I’m in and get a more realistic horsepower and torque number,” he said. “I’m looking to support these injectors with an Irate Diesel electronic fuel system, bigger oil pump, turbo, head studs, and valve springs.” In my opinion, I like that the guys are still upgrading these old trucks. I look forward to seeing how that truck turns out in the future.

Our next truck is owned by Blake Mayfield. It’s a 1999 Dodge Ram 2500 with a 5.9-liter 24-valve Cummins with a stock turbo

Under the hood of Blake Myfield’s Ram we fins 150-horsepower BD Diesel Performance nozzles, Edge Products Comp Box with Hot Unlock, boost elbow, a built transmission, and billet torque converter.

Blake has really turned this truck into a fun daily driven machine. Before today’s event, he said that he’s more of a Duramax guy but… So, for those of you looking for a similar setup like this, at least we can hopefully give you an idea of what this setup is capable of.

While it may not look like a show rig, it still pumped out 390 horsepower and 856 lb-ft of torque. For a 21-year-old truck that really hasn’t got much money in it, that’s an impressive number. those 390 horsepower is just enough to melt the tires off on a weekend in front of your best friends.

“I was mostly happy with the results on the dyno. I was hoping to see 425 horsepower out of this truck, but the torque converter was slipping pretty bad,” said Mayfield. “Since it was slipping, I’m sure we are leaving quite a bit on the table but we’ll get it fixed and try again later on.”

Cody Mayfield’s 2001 Dodge Ram 2500 relies on a 5.9-liter 24-valve Cummins sporting compound turbos

With an S&B cold air intake, HX30/40 Hybrid / B2/S475 compound turbo kit, FASS 165 lift pump, Scheid Diesel Lightning VP44, drilled crossover tubes, F1 Diesel Mach 7 240-horsepower injectors, fully balanced rotating assembly, block stiffener, Helix 2 camshaft, 5-inch exhaust, South Bend 3600 dual-disc clutch, and a Smarty/Edge Products Comp Box We have high hopes for a big number. Cody is Blake’s twin brother, and with these large injectors and a stout driveline, this truck should be impressive on the rollers.

Cody Mayfield’s Cummins was up next on the rollers but during its outside idle time (it was extremely cold) it was struggling to stay running. This wasn’t a good sign heading into a dyno session where we’re looking for the best performance. After tinkering in the parking lot for a few minutes, Mayfield decided enough was enough and it was ready.

Unfortunately, the dyno didn’t go as planned. “The truck was dying right before I was about to open the throttle up but this camshaft code kept popping up and it actually died completely once while on the rollers,” he said. “I believe this cam sensor was intermittent and the real reason why we didn’t get the numbers we wanted.” Mayfield’s Ram made it just past the 550 horsepower mark.

Austin Gribler owns this 2014 Ford F-350. Under the hood is a 6.7-liter Power Stroke.

Just like our previously listed trucks, Austin Gribler relies on an S&B cold air intake, five-inch Flo-Pro exhaust, PPEI-tuned EZ-LYNK AutoAgent, H&S Motorsports cold side intercooler pipe.

Gribler is passionate about diesel trucks and has an interest in pushing his truck further in the upcoming days. From what I’ve gathered, this dyno session is to get some data and figure out where he and his truck stand at this point. These 6.7-liter engines have serious potential, so I’m looking forward to seeing what it does here.

When the rollers stopped, 438 horsepower and 896 lb-ft of torque later, Gribler was pleased. “I feel pretty decent about the dyno results considering the amount of work. I mean, it’s only tuned with exhaust, you know?” said Gribler. “Out of all of the trucks here, it was the most consistent ranging only five-horsepower away each pull and the torque number was within one number. It was consistent, to say the least.

Quentin Miller’s 2006 Dodge Ram 2500 is powered by 5.9-liter 24-valve Cummins

We start our modification list with a Stainless Diesel exhaust manifold, S488/96/1.32 turbocharger, 250-percent Exergy Performance injectors, Dual PPE CP3 injection pumps, ARP head studs, valve springs, pushrods, D&J Precision Machine connecting rods, 12-MM main studs, and girdle, and a FASS 260 lift pump. With a single 88mm turbo and a set of 250-percent over injectors, this truck should lay down a number. Also, with a bed full of nitrous bottles, we may even get to see some flame action.

Miller was thrashing to get this thing ready before dyno day and then struggled to keep the nitrous bottles warm on the coldest day of 2020. But, he pushed forward and made the best of what he had. After three pulls, Miller’s ’06 had the best pull of 1,075.25 horsepower and 1,506 lb-ft of torque. While that is a great number, Quinten really expected more.

“I’m not really super pleased with the numbers that it made but I also can’t be mad because it is just a stock cylinder head and it is the smaller displacement 5.9 engine,” he said. “This is a lot of turbo for a 5.9. I’m looking to get some head work done to this one and get the tuning logged and lined out and we’ll be ready to go back. I know this setup has more in it and we’ll make it happen.”

Jeremiah Lintner has this 2008 Ford F-250 powered by a 6.4-liter Power Stroke

With 59/72mm compound turbochargers, ARP head studs, aftermarket up-pipes and air intake, No-Limit Diesel intercooler plumbing, FASS 150 lift pump, custom tuning, and a set of 30-percent over fuel injectors, Lintner’s F-250 was certainly decked out in accessories. But it was also sharply dressed under the engine bay. With two turbos and a good fuel system, this truck should make for a fun street truck.

During the dyno pulls, the truck kept wanting to downshift causing a huge, inconsistent spike in torque and not displaying the horsepower number Lintner was really after. Our advice to Lintner was to get a tap shifter from BD Diesel and be able to lock that baby into gear and get a more accurate reading.

Cody Schlosser’s 2006 Dodge Ram 2500 with a 5.9-liter 24-valve Cummins

Cody’s truck features an Industrial Injection Silver Bullet 66, 100-percent over injectors, 12mm Exergy CP3 pump, FASS 165 lift pump, and a built transmission.

Schlosser plays in the world of sled pulling and Big Bertha here has been the test subject. Schlosser has put some good hard parts on this truck and was really looking for 800 horsepower. He’s got the recipe to do it, but there is only one way to find out if he has enough.

It landed at 728 horsepower and 1,442 lb-ft of torque. He was having some issues keeping the radiator cap on in later pulls and it was puking a little bit of coolant out but that was the best of his attempts. The truck runs great and is a true contender when it comes to local sled pulling but Schlosser stressed that he has plans for this rig later on.

“The dyno for me was okay. Honestly, I was expecting a little more power but it is what it is,” he said. “I’m going to leave it alone for now due to lack of funds.” We feel you on that one, brother. He continued, “I wouldn’t mind adding a different turbo to the manifold or even just adding a second turbo on there and running a good size set of compounds.”

We cannot thank Greg Adams here at Greg’s Tuning Operation enough for making this happen. Its convenient location allows here in the southern Missouri area to be able to put things like this together. If this is something you want to do with your truck and find out the power and torque it makes, hit up Greg and schedule some dyno time today.
