In the quest for more horsepower we look to power adders such as turbochargers, superchargers, and nitrous oxide to fill that need. All three methods are viable ways to increase your Mustang’s horsepower.

For Coastal Dyno’s Sam Lippincott, he had his ’15 Mustang GT up to 440-rwhp with a full American Racing Headers exhaust, a JLT Performance intake, and a Coastal Dyno tune using HP Tuners software. With Weld Racing RT/S wheels and Mickey Thompson ET Street radial 275/40/17s, the car ran an 11.66 at 117 mph at Bradenton Motorsports back earlier this year. The car had a Shaftmasters one-piece aluminum driveshaft and Ford Racing half-shafts when he ran the 11.66. At that time, the rear IRS boasted stock bushings.

Just a stock engine with a ProCharger D-1SC supercharger system. You’re looking at 700-rwhp on pump gas.

Lippincott’s need for more power led him to install a ProCharger D-1SC supercharger system. ProCharger has two ’15 Mustang GT systems that use the P-1SC head unit. That is ProCharger’s base head unit, if you will, but the P-1SC is available in an HO, and Stage II form. The HO has the base intercooler and shared serpentine belt drive. The Stage II kit has a larger intercooler, and a dedicated blower-only belt drive.

The D-1SC head unit is an upgrade available from ProCharger within the Stage II line-up. Upgrades are available up to, and including ProCharger’s F-1R supercharger. With the D-1SC you can still use with a stock engine, but the F-1R is really designed for built engines. The D-1SC system uses the Stage II intercooler and dedicated blower-only belt drive. The belt drive is also an 8-rib set-up, not a 6-rib.

You’ll notice the stock front bumper cover in this image of the car from back at the NMRA Spring Break Shootout. In the dyno shot you can see the car now has a Roush front bumper cover for the larger opening to provide air to the Stage II intercooler.

With the D-1SC on board, Lippincott’s first pull resulted in 648-rwhp at just under 6,400 rpm. Remember the car made 440-rwhp naturally-aspirated. That’s already a 200-horsepower gain on just the first pull. On the second pull, up to 6,600 rpm the car made 675-rwhp. So far the D-1SC made 15 psi of boost using a 4.38-inch pulley on pump gas with ID1000 fuel injectors and a JMS Chip and Performance PowerMAX FuelMAX fuel pump voltage booster with the stock fuel pump.

After letting the car cool down over lunch, Lippincott went for the glory run, which netted him 712-rwhp at 6,800 rpm. Boost stayed at 15 psi. That’s impressive when you can take a stock engine, add an out-of-the-box supercharger kit, and make over 700-rwhp.

The ’15 might’ve just earned a trip to the drag strip, where Lippincott hopes to run deep into the 10s. Stay tuned.
