National Auto Sport Association Northwest inaugural independent event at Oregon Raceway Park in Grass Valley, OR — the Checkered Flag Fever weekend. Oregon Raceway Park is a 2.3-mile, 16-turn road course with 400 feet of elevation change and a distinctive 16-degree banked turn, set in the rolling hills of southern Oregon.
It’s one of the more technically demanding tracks in the Pacific Northwest, with a mix of blind crests, fast sweepers, and tight technical sections. This is part of NASA Northwest’s first season as an independent region, making it a landmark event for motorsport in the Pacific Northwest. The event offers three participation formats:

High Performance Driving Education (HPDE) is the entry point for drivers new to track events. Cars run in groups organized by experience level, with in-car instruction available for newer drivers. The focus is on building skills in a safe, controlled environment — proper lines, braking points, flag awareness, and car control. No competition license required.

Time Trial is for licensed competitors running against the clock in structured sessions throughout the weekend. Drivers compete for fastest lap times within their class. A NASA Competition or Time Trial license is required.

Sprint Racing is wheel-to-wheel competition in shorter sprint race formats. Drivers compete in classes based on car and modifications. A NASA Competition Racing license and current medical examination are required.

All participants must pass a tech inspection before driving. NASA membership is required — annual memberships and event registration are available at members.drivenasa.com.
