M6G members from the Houston S550s club gathered this weekend for a dyno day hosted by our friends at PSI Motorsports.
Thirty-one S550 Mustangs and even one brand new Race Red Shelby GT350 with track pack made their way out to Kemah, Texas, just outside of Houston to run their 2015-2016 Mustangs on the dyno for some friendly competition of rear wheel power.
Steeda Autosports was also kind enough to donate a Steeda catch can and short throw shifter rod as prizes and although it took all morning through mid-afternoon to finish running all 31 S550s, to the victors went the spoils.
See who had the highest horsepower in all three categories.
