The NMRA All Ford World Finals in Bowling Green, Kentucky is still going on, but one new record has already been set - Watson Racing brought out their S550 Mustang to the NMRA Finals and ran their former SEMA Show car head to head against the field. This time around, their Mustang ran well into the 8-second territory. It's the second S550 Mustang to run in the 8s and the first IRS equipped Mustang to accomplish the feat.

Powered by a beefy Holbrook Coyote 5.0L V8 with a 2.9L supercharger, Chuck Watson Sr. Clicked off a best of 8.90 at 153 mph. The Watson Racing 2015 Mustang was also part of the highly anticipated Grudge Races as it lined up against Kelly Aiken and ran an 8.94 to Kelly's 9.73.
