Scrapyard Savior: Industrial Injection’s Silverado 2500 HD

Brett Williams’ ’01 Silverado 2500HD Goes From a No-Pay Orphan to a 2,300hp Rocket Ship

To those in the know, Salt Lake City–based Industrial Injection is one of the places to go for diesel performance. With all the accouterments necessary for Ford, General Motors, and Ram owners to maintain (or modify) their trucks, oil-burner fans in Salt Lake Valley would do well to check out the shop.
That’s what the former owner of this ’01 Chevrolet Silverado 2500HD knew when he dropped it off for some maintenance, but he never could scrape together enough cash for the new injectors it needed. With the man unable to retrieve the truck, it sat in the Industrial Injection parking lot for a long, long time.
“After four years of it sitting in our parking lot, I decided to call the guy and tell him to come get it,” says Brett Williams, who, along with his brothers and parents, owns and operates Industrial. “He had some financial trouble on his end, and he offered to sell it to me, so I bought it for five grand.”
Brett initially only planned to change the injectors and resell the truck for a tidy profit, but with 250,000 miles on the odometer, it needed a bit more attention than that.
“I was also going to do some minor work on the engine, and while we were working on it, we broke a head bolt,” Brett says. “After that, we decided to put a race motor back in it and turn it into kind of a sales tool.”
With the hopped-up engine installed, the truck made about 1,000 hp, and a set of CalTracs traction bars and grippy tires helped it put down some decent numbers at the dragstrip. But as any enthusiast knows, “decent” is never enough. A full competition engine was installed, and the Allison five-speed automatic transmission got swapped out for a Dodge 47RE gearbox, both of which were built to Industrial Injection’s standards.
The 6.6L Duramax LB7 V-8 was treated to a billet crankshaft, forged pistons, an Industrial Injection reverse-firing-order camshaft, billet connecting rods, custom ported race cylinder heads, and some seriously powerful injectors, while the 47RE, which was built by Randy’s Transmissions, enjoys a suite of high-stress internals, a manual valvebody, a SunCoast torque converter, a Precision Performance Products air shifter, and, obviously, a Duramax adapter plate.
Most interestingly, the Chevy also enjoys a constant stream of diesel, thanks in part to Industrial Injection’s unique triple-CP3 injection pump setup. The kit combines with King Cobra injectors and two Fass lift pumps capable of moving 260 gph each. With a custom compound-turbocharger kit consisting of an 80mm BorgWarner S400 feeding a 106mm S510 (made by Industrial, naturally), the engine is capable of making a dyno-verified 2,000-plus horsepower. In fact, the highest number yet achieved by the truck is 2,297 ponies, as well as 3,499 lb-ft of torque.
Brett says it’s been hard to reach that number, not because the truck isn’t capable, but because finding a chassis dyno that’s able to measure the power has been difficult. Strapped to the Industrial Injection dyno, the rig pegged the rollers at 2,000 hp from 120 mph to 170 mph, maxing out the shop’s measurement tool’s rating over a span of 50 mph.
Even so, Brett’s not even close to finished with the project. In the hands of his capable driver Dallas Hunt, the Silverado runs high-9-second quarter-mile e.t.’s, but Brett tells us there’s more on the table. A truck with more than 2,000 hp should launch itself solidly into the mid- or low-9s with a little fine-tuning.
Thanks to the family-centric aspect of his business, Brett hasn’t had much trouble finding support from his parents, brothers, and wife. “They’re all on board, and they all want to see what the truck will do,” he says. With an 8-second quarter-mile on the horizon, we can’t wait to witness what happens next with Industrial Injection’s orphaned Silverado.

Fun Fact:
Its former owner abandoned the ’01 Chevrolet Silverado 2500HD for five years in the Industrial Injection parking lot. After the owner offered to sell the truck to Brett rather than retrieve it, the rig became a shop truck, then a mobile billboard, then a rolling showcase of Industrial’s performance prowess.

Although it wasn’t intended to be a gleaming show truck, it’s impossible not to be impressed by the Industrial Injection Chevrolet Silverado 2500HD. Its purposeful stance, unreal performance, and no-nonsense details make it a wholly different kind of beautiful.

An Industrial Injection custom compound-turbocharger system provides the compressed air, while the company’s concept triple CP3 injection pumps and twin Fass lift pumps keep the crude a-flowin’. The end result is a stupendous 2,300 hp.

A Rollover Motorsports custom rollcage and Corbeau bucket seats keep driver Dallas Hunt securely behind the wheel, hand gripping the Dodge 47RE four-speed automatic transmission’s manual shift lever. The interior is certainly all-business, with no creature comforts to be seen.

Controls for the air shifter fall readily to hand.

Details, details. A headlight-replacing air inlet feeds the massive compound-turbo setup, while the drilled matte-black grille is just there for the sake of coolness.

Industrial Injection’s chassis dyno is only rated to 2,000 hp, so when the Duramax pegged the rollers at that number from 120 to 170 mph, Brett knew his truck had more to give. A trip to a dyno in Montana proved that, posting a 2,297hp pass.

Seen at racetracks all over the West, the Silverado has posted e.t.’s in the high-9-second range. Brett wants to crack into the low 9s by the end of 2016—and we want to see that happen.

Dallas will certainly be showing off a few more of these trophies if Industrial’s former shop truck continues its upward performance trajectory. Dallas’ good driving gets tons of credit here too, though.
