HPT Turbochargers Returns as Title Sponsor of TSO for 3rd Straight Year at 2026 Buick GS Nationals
Three years strong—and we’re just getting started.
HPT Turbochargers is proud to announce our return as the Title Sponsor of the Turbo Street Outlaw (TSO) class at the 2026 Buick GS Nationals, taking place April 29 – May 2 at the iconic Beech Bend Raceway.
The Buick GS Nationals is one of the most legendary events in the turbo Buick world, and the TSO class continues to deliver some of the most intense, no-holds-barred racing of the entire weekend. Being part of it for the third year in a row is something we don’t take lightly.
The class is organized by Steve Kessler, who continues to push the program forward year after year. Beyond running the class, Steve is also an HPT Turbocharger customer himself—currently running an F3 7275 on a stock bottom end 231 combo. At 3,750 pounds, his setup has already laid down an impressive 10.43 @ 132 MPH in the quarter-mile. It’s a perfect example of real-world performance with HPT under the hood.
“HPT Turbochargers has always been about supporting the racers who actually use our products,” says Harry Hruska, Founder & CEO. “TSO is one of the most exciting classes in Buick racing, and Steve does an incredible job building something special for both racers and fans. We’re proud to be back for year three.”
