The EndAfter the dust settled, it was time to hand out the trophies and say goodbye to the class of 2007. Once again, we were totally impressed with the sportsmanship exhibited by Diesel Power Challenge contestants. There's no professional sport where you'd find guys willing to help the returning champ get the competitive edge, but we saw a swarm of drivers descend on Micheal Tomac's Chevy to help him rock the truck and make room for more fuel before the mpg test. We also heard plenty of drivers exchanging tips and tricks throughout the event. In other words, thanks to the competitors for making the '07 Diesel Power Challenge a great event. Even though everyone who gets invited to the contest is a success story, we can have only one winner. Flip the page to find out who took home the top prize, and then check out the scores on page 92 for all the details.
Editor David Kennedy personally refilled each truck after the mpg loop. Even with the difficult conditions of this year's course, two of the six remaining trucks got more than 20 mpg, and another achieved 19.99 mpg. | 
Micheal made it look easy as he pulled the sled past the 300-foot line during his first two passes. Homemade ladder bars and bumpstops, a stiff rear lower leaf spring, and a ground-sensing radar setup helped him transfer his 750 hp into the dirt. |

Shawn had no problem hooking up with the track during his first two passes down the track. Both runs didn't end until he'd passed the 275-foot mark, but he was just short of the distance needed to get into the final round. |

Randy had never pulled a sled before, so he knew he had nothing to lose and boosted his truck to 15 psi before launching in 4-Lo. Both of his pulls were steady runs that dragged the hammer sled out past the 150-foot line-not bad at all for a first-timer. |
Jorge was also a rookie to sled pulling but had lots of upgrades in his arsenal. In addition to a big Industrial Injection Phat Shaft 71 turbo, the Mega Cab used BFI injectors by Industrial Injection, an Industrial Injection dual CP3 kit, a FASS lift pump, a Bully Dog programmer, a TS performance MP-8 fuel box, a Van Aaken C-5 Smart Box for pulling, a Ray Mac head held with ARP titanium studs, a MaxSpool 2 camshaft, and a ZZ Fabrications intake with built-in nitrous spray rails. | 
James built his own temporary bumpstops with washers from the hardware store to improve his traction during the sled pull. His first sled pull (ever) went beyond 240 feet. |
With his boost problems solved, Mike abused the sled-pull track with two runs beyond 300 feet. That put him into the final round, where he dominated the competition by out-pulling both trucks by at least 120 feet. | |
