Fastest Ford Mustang at SEMA 2015
The Ford Performance Cobra Jet may be the quickest Mustang at the SEMA show in Las Vegas, but past a quarter-mile, Doug Paddocks 2012 GT would leave the CJ in the dust! That’s a bold statement—but with a certified top speed of 215.4 mph in the Colorado Mile, this GT is “The Boss” of extreme velocity. In fact, Doug calls this sinister Black GT “El Jefe,” which simply translates means, “The Boss.”
Doug’s quest for extracting huge speed from this GT began on the drag strip, not long after he drove this Hellion-equipped street-legal Stang into the 9s. “A friend owned the car, but he wasn’t licensed [for NHRA competition] so he asked me to drive and the first time out it went 9.40s at 140. That was in Denver at 5,000-plus feet elevation with a MMR 1000 engine and the 6R80 transmission,” said Doug.
“It was a fast street car—I offered to buy it and he said ‘SOLD!’”
With the help of Justin Kill, we started fabricating parts in our chassis shop called Overkill Race Cars. We built a K-member, control arms, a manual rack conversion, and rear suspension links.” Doug also added Strange struts, Menscer rear shocks, a Ford 9-inch and he switched to a 4L80 automatic transmission built by Ace Transmissions in Dallas. The new combo also uses a Circle D Penta-Series converter with five-disc lockup.
El Jefe is powered by a unique 5.2L Coyote prepared by Jeremiah Hussy of Modular Performance Solutions. To bump the displacement, they machined the block to accept gussets and sleeves, which allow oversized Manley pistons, Manley rods (stock length) and a standard Boss crank. A set of worked Boss heads move air to the awaiting valves that are set into motion by custom-ground cams.
Boost is everything on this beast and the big wind is generated twin Precision PT6466 CEA turbos mated with a Hellion kit. Compressed induction air is chilled by the Precision liquid-to-air intercooler before it’s fed to the Boss intake. E98 fuel is pumped by a Fore triple-pump setup and fed with ID 2000 injectors that are controlled using by an AEM Infinity 8 ECU. With 29 psi of boost on tap, the 5.2 recorded 1,650 rear-wheel horsepower.
And while thousands will see the Mustang sitting calmly in the Precision Turbochargers barn at the SEMA show, running on track is where this pony shines. “We went to the Colorado Mile at Front Range Airport and went 202 mph on the first pass,” Doug told us. “We upped the boost for the second pass and ran 215.4 mph, but had a small fire caused by some of the heat shielding. The damage wasn’t major, but it was enough to end our day,” he added.
Setup for the mile includes a large intercooler and True Forged 19s and 20s with Toyo 888s meeting the runway. Vehicle weight is a hefty 4,012 pounds and you can see the various body mods to help it slice through the air. El Jefe also sees quarter-mile action, where it gets a smaller intercooler, 4.56 gears, Weld V-Series wheels and Mickey Thompson 17s in the front and 275 Drag Radials in the back. It has run 9.03 at 159 mph—at 8,700 feet corrected altitude! “One key is the Precision Hyperkontrol. It uses wheel speed for boost management. We leave with 1 psi, it ramps in boost based on wheels speed and rate of acceleration and we go up to 21 psi.”
“It has morphed into something I didn’t think it could,” Doug said in a humble voice during SEMA. “The attention has been overwhelming, and I appreciate everything. I couldn’t do this without Joe K, Roger Connely and Harry Hruska of Precision Turbo, Joe Opolski, Justin Kill and my wife Michelle and my kids. Moving forward we’re focusing on a new exhaust housing and ultimately we’re trying to go 250 mph at the Mohave Mile.”
Amazingly, the Ford Mustang is still street legal. “I take the car and down to the pet store with my dog, it’s still fun to drive around,” Doug told us—and we believe him. Actually, we’d love to head to Denver and hit the street in this GT. Or better yet, drive it home from the SEMA show. Hey Doug, what do you think about that?
