When you get hooked on playing with horses, you quickly get addicted to horsepower. That’s definitely the case for SVTP member, Curtis Smith (REDS197). He recently stepped up from a late-era S197 to a brand new Mustang GT, and he’s already making big power with it.

Under the hood, Curtis upgraded his new-school Coyote with a VMP Gen2 TVS supercharger cranked up by 5-percent-overdriven crank pulley and 72mm blower pulley. It is fed by a Ford Performance Racing Parts twin 65mm throttle body and a Roush Performance cold-air intake. The exhaust features a high-flow mid-pipe and a Magnaflow cat-back. A set of billet oil pump gears from Triangle Speed Shop ensure its durability, and a custom tune from Ken Bjonnes of Lund Racing makes the combo work together.

“I have had over a dozen Mustangs. I am a diehard Mustang fan. Most recently I had an 2007 Shelby GT and 2013 GT,” Curtis said. “Both had boost in the form of positive-displacement blowers. I really like the styling of the 2015, so I sold my ’13 on SVTPerformance, of all places, and ordered a 2015.”

Curtis definitely picked a good spot to sell off his S197, but he wasn’t moving up to the new Mustang with the idea of keeping it stock. Instead, he had big plans for the car, including doing all the mods himself.

Eibach lowering springs set the stance on Curtis’ 2015 Mustang GT, which rides on Forgestar F14 wheels wearing a custom-powdercoated Matte Bronze finish. They measure 20x9.5 inches in front and 20x11 inches out back. They are shod with Nitto 555 275/35-20 front tires and 555R 305/35-20 rear tires. The car’s Super 8.8 rear is upgraded with 1,400-horsepower halfshafts from The Driveshaft Shop. It also features a one-piece aluminum driveshaft from D.S.S.

“I like driving a manual so I always buy positive-displacement blowers for the instant hit. VMP Tuning helped me run a 10.43 at 134 here in the Denver altitude (7,500-feet density altitude), so I wanted to try the Gen2 on the 2015,” he explained. “With the new heads and cams, I want to see how far I can push the stock motor. I have done 100 percent of the work by myself, other than the tune. My goal is a 9-second slip in Denver with the stock IRS and stock motor with a manual.”

Supporting the boosted engine is a full complement of well-chosen mods. A JPC Racing Budget Return System with twin 465-lph fuel pumps supply enough volume for the Injector Dynamics ID1000 fuel injectors to feed the boosted engine with plenty of E85. With that combo in place, Curtis turned to Ken Bjonnes of Lund Racing for a custom tune to maximize the combo. All told, the car put down 777 horsepower and 638 lb-ft of torque to the rear wheels.

“The car is a monster. I can hook the Nitto Drag radials 305/35-20 on the street in second gear. The IRS really does help it hook better than a solid axle,” he added. “I am impressed how it squats and goes with little issue. The new heads definitely make it rev much easier.”

Right now, Curtis’ rear suspension is only augmented with differential bushings from BMR Suspension, but he is eagerly awaiting the release of the company’s cradle braces. He may need that extra support as he strives for his e.t. goal in the Colorado altitude.
