NHRA officials announced today that Holley EFI will be the title sponsor of the Factory X category for the upcoming NHRA season. Factory X is a category exclusively dedicated to 2019 and newer manufactured automobiles, featuring musclecar models such as the Chevrolet COPO Camaro, Dodge Challenger Drag Pak, and Ford Mustang Cobra Jet.
NHRA Holley EFI Factory X will participate in eight events throughout the 2024 campaign. The first race will take place at the NHRA Four-Wide Nationals on April 12-14 at The Strip at Las Vegas Motor Speedway.

Having appeared at four events in 2023, NHRA Holley EFI Factory X, which combines supercharged Hemi, LS, or Coyote engines with manual transmissions and lightweight factory-appearing bodies, has captured the attention of drivers and race fans alike.

Jason Bruce, Vice President of Sales at Holley Performance Products, expressed excitement about their involvement and the class’s growing popularity. 

“Holley has been a part of NHRA since its inception, and we have enjoyed progressing our business from carbs to modern EFI. It’s a huge thrill to continue to be involved with NHRA Factory X and to see the evolution of this amazing new class,” said Jason Bruce, Holley Performance Products Vice President of Sales. “These cars are just so exciting and provide a great new cool factor for NHRA fans. We’re seeing interest growing and new cars being built, and you can feel the excitement for this class continuing to build at a very fast rate. These Mustangs, Camaros and Challengers truly represent what a modern muscle car is and it’s a class that has really caught on with the fans as well, and that’s great to see.” 

The NHRA Holley EFI Factory X schedule begins in Las Vegas, followed by races in Charlotte, Chicago, Norwalk, Indianapolis, St. Louis, Dallas, and the finale back in Las Vegas.

This new class has already provided a home for former NHRA Pro Stock racers, most notably Allen Johnson, who became the first to break the 200-mph barrier at the St. Louis race. He was also the first into the six-second zone, albeit in a private test session.

Brad Gerber, NHRA Vice President, and Chief Development Officer, praised the partnership with Holley and expressed optimism about the future of NHRA Holley EFI Factory X. 

“NHRA Holley EFI Factory X is such an outstanding class, and we’re thrilled to partner with a company like Holley that has recognized the great potential in this category,” said Brad Gerber, NHRA Vice President and Chief Development Officer. “The class enjoyed a very successful debut in 2023, and it’s going to be very exciting to have NHRA Holley EFI Factory X race its first full season in 2024 and compete at eight NHRA national events. When they’re on the track, they put on an incredible show and it’s going to continue to be a huge hit with fans.”

Cars in NHRA Holley EFI Factory X have a minimum weight limit of 2,650 pounds, nearly 1,000 pounds lighter than a Factory Stock Showdown (FSS) car. Additionally, a manual transmission is mandatory, and each body must be OEM dimensional, with no alterations allowed.
