Update: Mustang GT Power Pack Could Add 60 HP For $2,395

Late last month, we reported on a suite of so-called “Power Pack” upgrade kits inbound from Ford Performance for the V8-powered Mustang GT. Available in three different levels of “oomph,” these Power Packs use new ECU calibrations and simple, bolt-on induction bits – many of which originated on the Shelby GT350 Mustang – to bolster output.

At the time that the news broke, we repeated what Ford Performance itself had written about Power Pack 3: that it could boost peak output in the regular old Mustang GT by up to 60 horsepower at 7,000 rpm. We suspected that might have been a typo.

Now, we have corroborating evidence in the form of a piece published by The Drive. That outlet spoke to Ford Performance spokesperson Matt Leaver, who said that while individual mileage may vary, a peak horsepower rating between 475 and 495 horsepower would represent “a reasonable number at the flywheel.” Power Pack 3 for the Ford Mustang GT is priced at $2,395, although installation will of course run extra.

The Drive points out that with the base price of the Ford Mustang GT ringing the bell at just $33,545 with destination, one could (in theory) have a brand-new, 495-horsepower pony car for a tantalizing total of $35,940.

All three Mustang GT Power Packs raise the 5.0-liter Coyote’s redline to 7,500 rpm, and according to Jesse Kershaw, Ford Performance Parts Product Manager, a Power Pack 3-equipped pony will pull hard all the way there. “Peak power is right around 7,100, but it stays fairly flat up until [redline],” he told The Drive. “Very similar to how the GT350 does.” That impressive peak output level does come at the cost of some low- and mid-range torque, however, so “for most street customers, the Power Pack 2 is the way to go.”

Power Pack 1 for the current-generation Ford Mustang GT was released earlier this month, with 2 and 3 slated for September and October, respectively. Be advised that the included 3-year/36,000-mile warranty is only applicable if installation is performed by an authorized Ford dealer.

  1. The problem on these set ups are that 7,500 RPM that can shorten the life of the GT’s Coyote engine.
    The Boss’s engine in the previous generation 5.0 code named “Road Runner”, went up 7,500 RPM but had forged pistons, while the Coyote 5.0 has cast pistons tested to sustain 7.000 RPM . Note that piston speed grows exponentially with RPMs, thus, I would not recommend to push a coyote 5.0 before upgrading to forged pistons (and Ford Racing’s oil pump) above 7,200 RPM

    • I’m not agreeing or disagreeing with 7500 RPM issues. However, piston speed can’t grow exponentially. It grows linearly with RPMs. Damage/vibrations could grow non-linearly at higher RPMs.
