During the 2017 Ultimate Callout Challenge the team from RevMax Performance did what no one thought possible by driving their competition truck to the Indianapolis event, competing in all three rounds of UCC competition then driving the truck back home to North Carolina. The truck wasn’t the only 2WD truck to enter the competition but it was the only truck that competed with a 68RFE transmission. In fact the team made it through the rigors of the competition on the same transmission they started with while many teams changed transmissions throughout the event showing that the crew at RevMax certainly knows how to build a stout 68RFE transmission.
Their 2WD shop truck is owned by Frank Kuperman Jr. but he turned the reins over to Tom Hauser for the 2017 UCC event. For 2018 Kuperman plans to slide back behind the wheel and pilot the truck himself. Hauser and the RevMax Performance team finished in 11th place overall with the overachieving underdog in 2017 and they plan to do even better in 2018 with more power on tap for the truck.
Kuperman and the RevMax team worked with Midget’s Diesel Performance on the build of the 6.7L Cummins engine reducing the stroke to make it a high-revving 6.4L powerhouse. Boost is created by a compound setup using a pair of Stainless Diesel S475/S480 turbos to develop plenty of boost and provide the engine with enough boost to keep up with the high performance fuel system. The fuel system consists of 450% over S&S Motorsport fuel injectors that are fed large amounts of high pressure fuel through a pair of Fleece Performance Engineering 12mm stroker CP3s.
While other trucks were radically reconfigured for each discipline of the Ultimate Callout Challenge Kuperman and the RevMax crew stuck with what got them there, literally. They adhered to the “run what ya brung” mantra and ran the truck in each event with only rear tire changes. They used a set of slicks to put the power to the drag strip, then returned to their street tires for the dyno runs and finished the event on an aggressive set of mud terrain dual tires on the rear axle for the sled pull.
Kuperman Jr. and his RevMax team are of course sponsored by RevMax Performance and they receive additional support from Higher Power Performance and Midget’s Diesel Performance to get the most out of their 2WD Dodge. As they refine and improve upon the truck and their team efforts they plan to tackle the 2018 Ultimate Callout Challenge while proving that 2017 was no fluke and that they can build a streetable truck that can perform at the highest level while being able to drive to and from the event. We look forward to seeing the truck drive to Indy then hit the track, dyno, dirt and drive back home once again on May 4th-6th 2018 at the third annual Ultimate Callout Challenge!
