The VMP STAGE 4 Power Pack!

The 2013-14 GT500 uses nearly 5 decades of experience to build America's state of the art Muscle Car. You'd think at 660+fwhp, we'd leave well enough alone, right? Haha, RIGHT! OK, so how about turning that 660 flywheel horsepower into rear wheel horse power? Still not enough? Fine....700 rwhp it is then!

Our experience with the '13 came early and VMP's modifying was well documented in Muscle Mustangs and Fast Fords Magazine.

VMP's GT500 STAGE 4 Power Pack for the 2013-14 Shelby has everything it takes to deliver up to a 100+ rear wheel horsepower increase!

  • SCT X4 handheld device, loaded with dyno and track proven VMP Custom Tunes by Justin Starkey
  • JLT 123mm Cold Air Intake to gulp copius amounts of fresh air
  • Black VMP 2.4" Press-On Pulley +2psi or 15-16psi
  • 90mm Idler to increase Belt wrap
  • Massive VMP Twin Jet 67mm throttle body

VMP's 2013 Shelby GT500 and many more VMP tuned cars have made over 700 RWHP & 700RWTQ with this setup.
