666 RWHP 2015 Ford Mustang GT ‘Blue Devil’

Plenty of all-encompassing options exist for the Ford Mustang GT owner looking for more power and performance from his or her pony. Hennessey Performance Engineering, Shelby American, Roush Performance, Petty’s Garage, and numerous other tuning firms offer comprehensive packages for 2015 and later Ford Mustang GTs.

Of course, sometimes you have to go it alone. The heavily-customized 2015 Ford Mustang GT “Blue Devil” California Special shown in the video above started off a run-of-the-mill V8 pony car before receiving a 2.9-liter Whipple supercharger, 132 mm throttle body, Corsa Extreme cat-back exhaust kit, and plenty more. The “Blue Devil” is rides on ADV005 alloy wheels from ADV.1, shod with Nitto NT05 tires, and we get to see the blown Ford Mustang GT both on the dyno, and committing acts of extraordinary violence against its tires on the street.

Allowing this Ford Mustang GT California Special to subject its tires to unspeakable torture is some 666 horsepower at the wheels, according to the video title (although the dyno shown shown on camera peaks at 660 RWHP). Assuming the usual percentage drivetrain loss, that would mean the “Blue Devil” is pumping out just over 780 HP at the crank – more than enough to surpass the 750 HP made by the Hennessey HPE750 Mustang, or the 670 made by the Roush Performance Stage 3.
