Not that long ago, "diesel" and "high performance" were mutually exclusive terms, with diesels being considered the slow-revving workhorses of the industrial world. But today, diesel-powered race trucks are delivering performances that would humble many a gasoline-powered hot rod. The National Hot Rod Diesel Association is one of the hottest diesel racing series in the country, and this week, some new world records were set for production-based trucks.

In the Pro Street class, Jarid Vollmer broke into the 8s with a scorching 8.81 second quarter-mile run at 157 mph. Per NHRDA rules, Vollmer had to run again with a time within 10 percent of the first run. Not only did he come close to his first run, but beat it by a tenth, coming in at 8.7 seconds at 159 mph, making him the current NHRDA Pro Street class world record holder.

Vollmer's truck is powered by a single-turbo Cummins with a stock engine computer running a custom-tuned Bully Dog tuner. Vollmer ended the day's competition in second place, and added 70 points to his season total, for 270 overall.

Nick Adamson, competing in the NHRDA's Super Diesel class ran a 11.91 quarter mile, and finished the day in sixth place, with a season total of 260 points, currently putting him at the top of the Super Diesel points standings.
