NHRA Top Fuel and Funny Car teams utilized the four-day pre-season test session (Feb. 3-6) of NHRA Nitro Spring Training at Wild Horse Pass Motorsports Park near Phoenix to prepare for the season-opening Circle K NHRA Winternationals, Feb. 11-14 at historic Auto Club Raceway at Pomona, California.
The Pro Stocks were not allowed at this nitro-only session, but will hold their own testing a few days later.
