Quite a few trucks were in the 500hp range on Randall’s Performance and Accessory’s chassis dyno during the shop’s all-day dyno event, including this 6.4L-powered Ford. Despite having 80hp nozzles and an AirDog lift pump to help supply fuel, the stock Siemens injection pump was unable to maintain rail pressure, culminating in a best run of 500 hp and 983 lb-ft. If injection pump and turbo upgrades are in the future, however, the Super Duty should make more than 600 hp.Quite a few trucks were in the 500hp range on Randall’s Performance and Accessory’s chassi It’s a shop most would say is out in the middle of nowhere—yet there always seems to be 15 to 20 Fords, Dodges, and Chevys in the parking lot. If trucks don’t show up at Randall’s Performance and Accessory to be repaired, turned up, or accessorized, they’re there to run on its state-of-the-art SuperFlow chassis dyno. This is why the folks at Randall’s host an annual open house and dyno day, during which their customers and other diesel enthusiasts get a chance to see how much real-world horsepower their rides are actually making. We headed to its facility, located in Gladstone, Illinois, to attend one of its all-day dyno events. We saw some impressive trucks grace the rollers and have provided the power-making recipes for the top three finishers. If you find yourself in the greater western Illinois or southeastern Iowa area next July, make sure you stop by and check out the event for yourself. This red LB7 Duramax represented the budget build quite well. Equipped with a ZF-6 manual transmission, a good clutch, and EFILive tuning, it put down 504 hp without a lift pump.This red LB7 Duramax represented the budget build quite well.

A 36-foot gooseneck trailer was positioned next to the dyno to keep spectators away from the rollers and offer them some protection.One thing we appreciated seeing was Randall’s attention to safety.

Once a slight rail pressure issue is addressed, he’ll be pursuing the 1,000hp mark on fuel. And, as the truck has made an 11.01-second quarter-mile pass in the past (back when the bottom end was stock), he wouldn’t mind dipping into the 10s with this wicked, street-driven Ram.With literally zero time to tune or dial the truck in, the triple-turbo’d Ram made 871 hp 667hp Ford Corey Finch Truck: ’06 Ford F-350 Engine: 5.9L Cummins (’05 engine) Internal Parts: Hamilton camshaft, pushrods, valvesprings, and ARP head studs Tuning: Smarty TNT Fuel: Dynomite Diesel 90hp injectors, Industrial Injection 85-percent-over CP3, AirDog 150-gph lift pump Air: High Tech Turbo 62mm over S475 Intercooler: Banks Transmission: ZF-6 six-speed with South Bend dual-disc clutch (3600) Believe it or not, this is Corey Finch’s tow rig. Even more impressive, on the dyno the Smarty programmer was set on its tow tune. When Corey ordered the F-350 a few years ago (with the ZF-6 manual transmission), the goal was to haul anything he needed to. But no matter what modification he added to the 6.0L Power Stroke, it still lacked the bottom end needed to get big loads moving.Believe it or not, this is Corey Finch’s tow rig.

With the factory wheels and tires, Tim Svob’s ’06 Quad Cab looks pretty inconspicuous. Of course, once the light turns green, the stock-appearing Ram gets with the program in a hurry. The best part about the build is Tim didn’t go overboard. He modified his CP3 himself, purchased Source Automotive’s competitively priced compound turbo system, and went with a subtle set of injectors. The end result was an affordable build that runs cool and has the potential to click off mid-12s at the dragstrip.Talk about a sleeper.
