Photo 3/9 | authoritative Testing timeslip | At the dragstrip, our timeslip of 10.28 seconds at 83.2 mph in the eighth-mile shows we have a long way to go as far as track times. Our 60-foot was horrendous, and so was our elapsed time. The vehicle’s trap speed was the only indicator of the truck’s true potential.
Photo 4/9 | authoritative Testing ram On The Dyno | We hit the dyno at Pacific Performance Engineering and were quite pleased with our horsepower and torque readings of 599 hp and 1,284 lb-ft. All the runs were made in Overdrive to avoid spinning on the rollers.
Photo 5/9 | authoritative Testing front Three Quarter Smoking | While we were fooling around trying to spool, our photo guy noticed a bunch of black smoke dumping out of the engine bay, so it’s clear we have a leak somewhere when the truck is under load. It’s just one more thing to check before we hit the track again.

Photo 7/9 | authoritative Testing nitrous Pressure Gauge | We got this -6AN to -6AN pressure gauge made by Nitrous Oxide Systems from Summit Racing so we could monitor our bottle pressure. There’s actually a port on the Nitrous Express bottle to mount a gauge, but that would require emptying the bottle of its contents. Upping the bottle pressure from 800 to 900 psi only gave us another 4 hp, indicating we were just out of fuel.
Photo 8/9 | authoritative Testing bottle Warmer | We also went through Summit Racing to get this bottle heater, which was made by Nitrous Oxide Systems. Since diesels run so much nitrous, a bottle heater is a very important part of the equation to ensure dyno pulls and dragstrip runs are consistent.
Photo 9/9 | authoritative Testing electrical Testing | It’s always the little stuff that ends up killing us. After we tested all our nitrous equipment to make sure it was working properly, we had two relays fail on the dyno. Thanks to some quick work by the techs at PPE, we were back in business in no time.
