To be honest, Maine is so far north, sometimes I forget they’re up there. But, in fact, they are up there and they are racing diesel trucks just like we down here in the central United States. As you know, we’re searching for the Fastest 50 in the states. So far, out of all of the submitted trucks, Lebanon-native Ryan Dyer takes the cake for Maine.

Dyer’s truck is a 2006 GMC 2500 Sierra HD with only 63,000 miles on the clock. Dyer purchased this truck just over four years ago and only after three months of ownership, the truck’s engine failed. Although most people would be absolutely devastated, Dyer took this opportunity and made the best out of it. “When the engine let go, that’s when the fun began,” said Dyer. “I pulled the engine out and replaced it with a newly configured engine and transmission put together by me. DyerMotorsports.”

This engine was put together by Dyer himself and he included a ton of goodies that would march him on to some of his best elapsed times. “CP Carrillo connecting rods, MAHLE Motorsport Pistons, SoCal Diesel As-Forged camshaft, SoCal billet flex plate, Wagler Competition Products main caps, and ARP main and head studs.”

Knowing that the engine that was under the hood now could handle a lot more, Dyer replaced some of the original add-ons for larger better ones. “At this point, I knew I had room to grow,” said Dyer. “I replaced the old Danville Performance 68R valley charger and S480 atmosphere with a Danville 72-MM and a Borg S484.” With that amount of air, Dyer went ahead and removed the pair of factory CP3 high-pressure pumps and replaced them with twin 10-MM Exergy Performance pumps and 200-percent over injectors.

Once the new engine was built and installed, the newfound power was really starting to work, Dyer was running into trouble at the local dragstrip. It was only after three passes that Dyer’s rig was already surpassing what the track would allow. “I was already into the 10-second range in the quarter-mile and the track wasn’t allowing me to continue until I had a roll cage,” said Dyer. “I was at a dilemma. I daily drove the truck but I love racing, so I didn’t want to cage it.”

Well, as he has in the past, by himself, he manufactured a full roll cage while keeping all of his interior and headed back to the track. Dyer’s best elapsed time in the eighth-mile is 6.88 seconds. Now, you’re probably thinking, man, that doesn’t sound that incredibly fast. Well, here is food for thought. At only 6.88 seconds, he’s doing this with a crew cab truck that weighs 7,239 pounds. That should put him over the 1,000-horsepower mark.

So, Dyer’s truck is making power, we know what it runs, and now he adds this. The truck has two kits of nitrous on board that has never been used. With that being said, that number could easily be lowered by the press of a button. What do you think of a full weight GMC into the mid-six-second range in the eighth-mile?
