Day two featured dynamometers and a BBQ and was held at the ATS headquarters in Arvada, Colorado. The day was filled with surprise and sorrow as participants strapped their trucks to the dyno to find out once and for all how much power their truck actually made. To lighten the load on its facility dyno, ATS contracted Haller’s Repair for use of its trailer-mounted inertia dyno. Trucks developing more than 900 hp were run on the inside dyno and trucks making less than 900 hp were tested on the trailer-mounted dyno outside. In addition to bragging rights, ATS awarded prizes for both categories down to Third Place.

Ron Seefeldt drove his brand-new...
Ron Seefeldt drove his brand-new stock ’11 Dodge Ram 3500 from Missouri to test the claims from Dodge that the 6.7L Cummins turbodiesel engine developed 350 hp and 650 lb-ft of torque. The trailer-mounted inertia dyno, named “Heartbreak Dyno,” recorded Ron’s truck at 303 hp and 610 lb-ft torque.
The menacing-looking front...
The menacing-looking front bumper on this ’02 Dodge Ram caught our eye, and it put down a respectable 415 hp and 764 lb-ft of torque. Bad guys beware, this monster has the power to catch and put a hurtin’ on you.
Johnny Ramirez, owner of Fusion...
Johnny Ramirez, owner of Fusion Bumpers, built this great-looking ’11 Ford F-250 to showcase the company’s product line. Most of the accessories are exterior, but Johnny did add a Bully Dog tuner to the truck and the results were 429 hp and 858 lb-ft of torque.
Tony Rizzi’s ’04 GMC dualie...
Tony Rizzi’s ’04 GMC dualie put down an impressive 776.64 hp on the dyno. His heavy right foot resulted in huge plumes of smoke and too much torque for the dyno to record.
A $0.50 boost tube clamp failed...
A $0.50 boost tube clamp failed during Misery’s dyno run. Owner Jerimiah Montgomery just shrugged it off—winning the dyno event paled in comparison to winning the drag race event the following day. When asked if there were any power-adders on this truck, in convincing unison the entire race team replied, “NO!” No nitrous oxide, no propane, no water-methanol injection—just great tuning and superior parts, ingenuity, and craftsmanship.
Shane Madden brought in this...
Shane Madden brought in this great-looking ’06 Dodge 2500. He was hoping to put down some impressive numbers on his daily driver. How did he do? 956 hp and 1,763 lb-ft of torque, which was good enough for Second Place in the dyno event.
This is what Tony Rizzi has...
This is what Tony Rizzi has under the hood of his ’04 Chevy Duramax dualie. His numbers on the Mustang dyno were 765 hp and 1,338 lb-ft of torque. The difference between the outside inertia dyno and the inside eddy current dyno was 11 hp or 1.5 percent. This result dispelled the rumors that the results of the two dynos were dramatically different.
The winner of the 2011 ATS...
The winner of the 2011 ATS Diesels on the Mountain dyno event was Dmitri Millard. Spectators were waiting all afternoon for the “Dmitri Dyno Show.” His was the last truck of the day to be strapped to the Mustang dyno. His fans were waiting for big numbers. And why not? In the recent 2011 Diesel Power Challenge he posted 1,300 hp and 2,300 lb-ft. After multiple attempts, his best numbers of the day were 1,387 hp and 2,497 lb-ft of torque.
When informed of the difference...
When informed of the difference between the two dyno results, Tony just smiled and said, “Let’s run it again!”
