History will be made this weekend during the 2024 NHRA 4 Wide Nationals as the Las Vegas event is the official launch pad for Holley EFI Factory X, one of the newest and most exciting classes in drag racing. Introduced more than three years ago, the class went from concept to reality in 2023 with four exhibition events. Now, Holley EFI Factory X makes its national event debut at a championship category this weekend in Las Vegas. The inaugural event features eight entries representing the performance models from Dodge, Chevy, and Ford.

The exciting new Holley EFI class combines supercharged engines, manual transmissions, and lightweight factory appearing modern muscle cars. Factory X engines are similar to those used in the popular FlexJet Factory Stock Showdown, but the cars are significantly lighter, use manual transmissions, and have larger rear tires. It took nearly three years to get the new class up and running, but so far, Factory X has been worth the wait as performances are nearing the six-second zone with speeds in excess of 200-mph.

Five-time Super Stock world champ Greg Stanfield won three of the exhibition races last year in his Chevy Camaro, which pays homage to the legendary Rod Shop team. Stanfield won in Indy, Charlotte and Las Vegas while the win in St. Louis went to former Pro Stock world champ Allen Johnson, who drove Geoff Turk’s Blackbird X Dodge to victory against Chris Holbrook’s Ford.

The 4-Wide Nationals is the first of eight events on the calendar this season with additional stops in Charlotte, Chicago, Norwalk, Indianapolis, St. Louis, and Dallas before finishing with a return to Las Vegas in October.

The entry list for the inaugural event includes Stanfield, who is now joined by his son, Aaron, and their teammate Stephen Bell. Turk’s car is now driven by versatile NHRA Pro Alex Laughlin while the rest of the field includes Jim Cowan, Lenny Lottig, Jesse Alexandra, and Rick Hord.
