ORANGE CRUSH

CRUSH A 1,200-HP PULLER BUILT TO DOMINATE
Mitch Meinhart is a diesel guy, there’s no doubt about it. While he doesn’t own his own diesel shop, he still decided to do a little sled pulling. Then he started to do a lot. Eventually, Mitch knew he needed a purpose-built truck in order to compete, so he retired his 80,000-mile Ram and bought a high-mileage ‘07 Ram 3500.

CUMMINS POWER

Horsepower is on a puller’s short list, and here Mitch started with a fresh 5.9L Cummins in order to make sure there were no surprises that would leave him stranded. After having the block machined and cam bushings installed, Mitch did the assembly himself, adding Carrillo connecting rods, flycut and coated cast pistons, and a 14mm main girdle from Industrial Injection with ARP studs. A steel 207/220 camshaft from Hamilton Cams was added (for high-rpm safety and airflow) along with Maxspool pushrods, springs, and retainers. A set of 12mm head studs from Extreme Studs ties everything together.

Where Mitch really got serious, was in the airflow and fuel departments on the upper end. The head was fully ported and polished by Harry’s Heads in Sioux City, Iowa, and fitted with inconel exhaust and intake valves for heat protection. The big oxygen generator on the truck is a S400-based 2.6 turbo, from JEB Modern Machine. Mitch and buddy Dan Bergman performed most of the fabrication work themselves, including designing piping to twin Frozenboost intercoolers, and building a custom intake. The fuel system on Mitch’s Ram is equally serious and starts off in a unique way with an Aviaid oil pump that’s used to push fuel. The high pressure system consists of a stock Cp3 with an Arson kit, and T&C Diesel 11.2 CP3 mounted up top. The final step to an estimated 1,200 horsepower is a set of 350-percent-over injectors from Exergy Engineering, and tuning from Firepunk Diesel.

POWER TRANSMISSION

While Mitch went fairly mainstream with the engine build, the transmission was a different matter. “Most people think I have a manual…but I don’t,” smiles Mitch. On tricky Iowa tracks, Mitch relies on a 48RE automatic built by Chris Schmitt entirely with Goerend Transmission parts. The unique slushbox has Overdrive locked out and a full-manual valvebody, along with aftermarket input, intermediate and output shafts, and a triple disc 2,800-stall converter–all from Goerend. When pulling Mitch stalls the truck up and leaves in 3rd Gear, and doesn’t shift when headed downtrack. This allows for a more controllable launch, and added converter multiplication at the start of the run.

CHASSIS

While the engine and transmission was being built, so was the chassis and drivetrain. Mitch built a ladder structure around the rear frame, and added 4.88 gears front and rear, along with a rear Yukon spool, front E-locker from ARB, and 38-spline rear axles. The rear end was also fitted with a 1480-style rear driveshaft, and a pinion brake, which helps the truck spool at the line without pushing through the brakes. Mitch also spent his late nights sanding the truck down, before it was sprayed a House of Kolor Angelo Pearl by Jessie Thompson.

With all his hard work, it comes as no surprise that Mitch started doing quite well. With more than 40 hooks under his belt, Mitch’s Ram was enough to take the Eastern/Central Iowa 2.6 points championship. Even after his win, Mitch still isn’t slacking off. He’s got a new RTC 3.0 smooth bore turbo for next year, has built a new stronger rear frame structure, changed rear axles, and extended the wheelbase up to the 158-inch class maximum. Mitch says he can’t wait to get the new changes dialed in, and we say that if you’re in Iowa, watch out for this tough unconventional automatic-equipped puller.
