Watson Racing 2015 Mustang

Watson Racing S550 has been to the show and the strip. It began as a SEMA project, then was used as a research and development test bed for more S550-related street/strip hardware. The Watson Racing S550 then was the first to hit 9’s, then 8’s and in 2015/16 was the World’s Fastest 2015 Mustang with IRS. Here is one of the original dyno pulls with the S550 at the Watson Racing Shop.

Choosing to forego the glitz that is sometimes the hallmark of SEMA cars, the focus was instead on function. To shed some 30 pounds of nose weight.  Watson’s experienced fabricators engineered a complete TIG-welded tubular K-member and front suspension setup. This chromoly cradle they bolted a 5.0L Coyote (built in house) toughened with Oliver rods and Mahle pistons. Tweaked with Ford Performance cams. Tuned via FAST XFI. Topped with a 2.9L front-inlet, twin-screw Whipple supercharger. Through a Tremec Magnum XL six-speed, the combo sent a “conservative” 927 hp and 702 lb-ft to the rear wheels.

Watson engineered and fabricated this complete tubular K-member/suspension package as part of the car’s weight-loss program. Watson Racing 2015 Mustang parts are now sold through the Watson Racing shop website.
