3300HP Ram Diesel Runs 4-Second Eighth-Mile at Ultimate Callout

June 14th, 2022

Ziegler Diesel Performance (ZDP) was on-hand at the Ultimate Callout Challenge in Idaho Falls, Idaho. They were rolling some serious coal!

After running an eighth-mile pass of 4.99-seconds @ 148.51 mph, the Ziegler crew strapped the mighty Ram onto the dyno. With the bleachers and infield positioned safely away from the machinery, the ZDP monster posted an unbelievable 3336hp and 3642 lb.-ft. of torque (at approximately 185 psi of boost). It was quite a moment for everyone in attendance.

The ZDP Ram is equipped with a 5.9-liter Cummins diesel, a compound turbo setup and a healthy dose of nitrous. It may be the most powerful diesel truck in existence. It certainly holds the record for best dyno pull.

Since the Ultimate Callout Challenge also includes a sled pulling event, we get the added bonus of another beast of a Dodge pickup. ‘Running in the Red’ is a sled pulling truck owned and operated by Calvin Miller. Just a glance reveals that it is indeed the daddy rabbit of the class. What a monster.

Enjoy the black smoke and burning brakes. This one is a hoot.
