Ring made the innovative call to go with a wild 103mm single turbocharger from Keating Machine, which is famous for building tractor pulling turbochargers. The monster turbo sends air through a Spearco intercooler and B&B Tooling side-draft intake. There’s also a little bit of nitrous on top in the form of a custom setup using Nitrous Express parts, a progressive controller and a unique spray bar in the intake.
With a monster rev range, Ring was able to forego the big shafts found in many racing transmissions and run with a standard-size billet shaft unit from Suncoast Diesel. The flexplate is also from Suncoast, as is the quaddisc torque converter. The 48Re-based trans also has a reverse manual valve body that’s programmed for 5,000-rpm shifts through the combination of a Racepak, EFILIVE tuning and a Precision Performance air shifter.
The rest of the Dodge has surprisingly few modifications outside of the drivetrain. Ring uses Afco double adjustable coilovers instead of the normal spring/shock setup up front, and the gear ratio was changed from 3.73 to 4.10 because of the engine’s high-rpm nature. Power is planted to the ground with a set of M&H slicks that help with the 1.3-second 60-foot times.
Ring and Manning are already planning on a “bigger and better” setup for the future. In addition to the 4x4, they’re also looking at running a 3,500-pound Pro Mod that should be ready by the end of the year. With a resume like this, we can’t wait to see what the next season brings for the team.
The factory accessory drive has been modified to drive a Waterman Racing lift pump, which creates more pressure and flow than the Cummins will ever need. With some 400% over injectors from Industrial Injection, it’s quite easy to drain rail pressure. A triple CP3 kit (also from Industrial Injection) keeps the engine at peak performance no matter the tune. Ring’s engine compartment isn’t just about performance. A custom valve cover from Beans Diesel Performance was made to add a little bit of style and humor to the engine bay. A Steed Speed exhaust manifold handles mounting the large-frame turbo and can withstand the extreme temperatures that the engine produces.
