I hope when she chooses a husband, he is an awesome gearhead so he can try to keep up with her. Jayden and Boo were here to watch the truck perform on the dyno and now Jayden decides she is going to pull this truck along with her Chevy! Jayden is one amazing young lady with a great future ahead of her. Boo is going to install twin straight stacks. This truck is a single stack with a stock muffler. On the dyno this old Mack Cummins put 570 horsepower to the ground, and with a 20% loss through the drivetrain, that equates to 712 flywheel horsepower. Being this is just a toy truck and Jayden’s father Boo Litman would drive it if necessary for their excavation company, we gave it some fuel. We did not remove the fuel pump, just made changes while it was installed on the engine.
The Mack was also equipped with a pyrometer. Next the competition turbocharger was installed, and a new torsional damper and mercury filled engine balancer along with a turbo boost gauge. The injectors failed the leakage test, so we recalibrated a set of Cummins Reman 400 injectors, increasing the flow to our 550- 600 hp spec. The number was not visible, so we installed the timing tool to verify the engine was an NTC 350, however the timing was set for 400 hp. The cylinder was good, so now we entered the combustion chamber with a borescope to get a part number off the piston. Upon removing the injector, we performed a compression test. With no knowledge of the engine, we noticed the number 1 cylinder had a miss. Keep in mind this accomplished young lady is only 14 years old and a freshman at Magnolia High School in New Martinsville, WV. She also rides a 2021 Husky 150 and a vintage YZ125 Yamaha and competes in flat track racing.
Jayden is a competition volleyball player, her position is the middle hitter and she stands at 5’11”, competes on a traveling team, has played in 7 tournaments in 3 different states, and carries a 3.6 GPA average in school.
Jayden says she pulls with the Duramax because it is the strongest engine in the pickups! With that statement I had to tease her and tell her she was in a Cummins shop and we love the Ram Cummins pickups. Her Chevy is a 2002 that her father bought new and she pulls in the street stock class. He then told me his 14-year-old daughter pulls one of them and she gets 750 horsepower out of the Duramax Diesel. However, he wanted it to run well and would work it at times, but the main use was to haul his 2 pulling Chevrolet pickup trucks to the truck pulls. About 1 month ago a gentlemen called me and mentioned he purchased an older Superliner Mack powered by a Big Cam 350 Cummins. You never know who is going to call, stop in, what they know and what they are capable of. What an amazing industry the diesel engine and trucking business is.
