Nick Priegnitz and his team from Calibrated Power Solutions was scheduled to compete in the 2017 Ultimate Callout Challenge with their Medium Duty 600 Cummins-powered 2011 Ram 3500 but the during their last tuning session the engine scattered its internals across the floor of the dyno cell. There was huge anticipation among many diesel enthusiasts wanting to see what the “Big Block” Cummins would be able to do in diesel competition, but unfortunately they were disappointed when the factory Cummins crank and rods did not hold up to the power goals Priegnitz and his team were aiming to hit.

While 2017 did not work out well for the Calibrated Power Solutions team, but they have rebuilt and plan to attack the 2018 Ultimate Callout Challenge with a vengeance. The Ram will be powered by the massive 9.8L Cummins ISL variant with a common rail setup that has a pair of 14mm Exergy CP3 pumps delivering high pressure fuel to custom injectors. Then to keep up with all that fuel they opted to go with a trio of S500 turbo chargers that should provide enough air for a massive beast of an engine like this 9.8L mill. The engine is backed by a fully built Dodge 47RE transmission with a manual valve body to allow Priegnitz to select the desired gear himself as he blasts down the track.

Priegnitz and his team have more than 10-years of high performance diesel experience under their belts and are among the top diesel tuners in the world that continue to push limits in high horsepower applications as well as clean diesel performance. The Calibrated Power Solutions team is supported and sponsored by Exergy Performance and Wehrli Custom Fabrication in addition to their own shop and crew. They are hoping to impress the UCC crowds with their out of the box thinking and Medium Duty “Big Block” Cummins powerplant while they attempt to prove the old racing adage that “there is no replacement for displacement!” Whatever happens, we look forward to watching Priegnitz and his team hit the track, rollers and dirt on May 4th-6th 2018 at the third annual Ultimate Callout Challenge!
