Randy Reyes

Two-time Ultimate Callout Challenge competitor Randy Reyes is an unconventional type of guy and that probably has a lot to do with his choice of a 2006 Dodge Ram 4-door dually for his competition truck. But, he sure does get a lot of performance out of that big, heavy truck, and it is still streetable with Reyes regularly enjoying the truck on the street breaking the hearts of Mustang and Camaro owners. Not only does he enjoy the truck on the street and race track, he also uses it as a test bed and proving ground for his high performance transmissions. What better way to push the limits of a transmission’s holding power than to put it to work behind a 2,000 HP truck that weighs nearly 8,000-pounds?

Coming in at a slender 7,700-pound race weight, Reyes’ big dually is motivated by an Industrial Injection built Shredder 5.9 Cummins engine that was built for maximum power in a reliable package. The Cummins engine is force few tons of air thanks to a compound triple-turbo system that features a pair of BorgWarner S488 turbos over an S500 that was designed and fabricated by the team at Industrial Injection. Of course II also worked their magic on the engine’s fuel system with high pressure pumps and injectors delivering more than enough fuel to keep up with the huge turbo array. Fuel is delivered from the tank to the high pressure pumps through a pair of FASS pump and filter systems.

During the 2016 UCC Reyes and the big dually put down 1,987 HP and 2,447.9 lbs-ft of torque to finish in 8th place in the dyno competition then delivered 1,898 HP and 2,469 lbs-ft of torque on the dyno to place 6th in the 2017 UCC dyno competition. The stout Cummins engine is of course backed by a 48RE Dodge transmission built by Reyes and his crew at Randy’s Transmissions. On the dragstrip in 2016 Reyes laid down an impressive 9.628-second pass that was good enough for 7th place but had trouble putting the power to the track in Indianapolis at the 2017 UCC where despite having six tires on the ground he seemed to spend as much time spinning the tires and getting sideways as he did going straight. He has also struggled with the sled pull finishing in 11th in 2016 and twisting the rear driveshaft and finishing in 17th in 2017.

Despite his troubles Reyes is one of few competitors that have competed in every single UCC event in both years and he plans to extend that streak in 2018 while remedying his traction gremlins on the Indy drag strip and redeeming himself on the pull track. Reyes and his team are supported by his shop Randy’s Transmissions along with additional support and sponsorship from FASS Fuel Systems, Gilly Fab, Hardway Performance, Industrial Injection, Nitrous Express, Simson Race Products, Suncoast Converters, TCS Canada and Yukon Axle and Gear to help the big dually finish well in competition. Whether or not Reyes and his dually win the 2018 Ultimate Callout Challenge we can be sure that the big truck will lay down tons of power and go bigger and faster than any big truck ever should. We certainly look forward to watching what Reyes and his team brings to the table for 2018 when the rubber hits the track, rollers and dirt on May 4th-6th at the third annual Ultimate Callout Challenge!
