2007 to 2014 Shelby GT500 Aftermarket Parts FAQ

The Shelby 4V GT500s were destined to become legendary as soon as they were announced. There's few things better than a massive, supercharged V8 under your hood. The 2007 to 2014 GT500s are just flat-out impressive and borderline insane vehicles from the factory. What's better than making them even more crazy? Adding a few GT500 suspension parts might keep you out of a ditch, or two, as well.

What exactly is under my hood?

2007 to 2012 Shelby GT500s come standard with a Ford 4V 5.4L DOHC V8 engine topped off with an Eaton M122H Roots-style supercharger. 2007 to 2009 GT500s put down 500 horsepower and 480 lb-ft of torque, while 2010 to 2012 GT500s threw down 540 horsepower and 510 lb-ft of torque through the use of a better intake system and revised tuning. 2013-14 GT500s come equipped with a 4V 5.8L DOHC Trinity V8 (with the same supercharger) that can make 662 horsepower and 631 lb-ft of torque.

What's your most popular GT500 part?

GT500 Clutches and Flywheels... and for a good reason. The enormous amount of power in the GT500 means that a few bad or hard shifts can pretty effectively slay your clutch and/or flywheel. With the way that some our customers throw their GT500s around, it's a pretty standard occurrence.

I actually know how to shift. What else?

Don't get snippy. One thing you need to know off the bat about the GT500s is that they are extremely under-tuned and it's ridiculously easy to make even more insane horsepower. GT500 Cold Air Intake and Tuner Packages are able to get you a whole boatload of horsepower and torque, and come highly recommended, as well as the Steeda Power Pak for both the 2007 to 2009 GT500s and 2010 to 2014 GT500s that includes a smaller pulley.

How do cold air intakes and tuning give me more power?

GT500 cold air intakes (CAIs) work by providing your engine with a larger amount of charge air at cooler temperatures than your stock air box or intake system. Tuning involves using a programming device to change some key parameters of your GT500's Powertrain Control Module (PCM) like fuel curves, timing, and other factors to produce more power. Combining a CAI and PCM tuning gets you a lot more horsepower and torque than using each one separately.

How does a smaller pulley get me more power?

Your supercharger is driven by your engine's own drive belt. The belt spins the pulley on the nose of your supercharger's head unit which causes the blower's rotors to likewise turn and force air into your engine's cylinders. A smaller GT500 Supercharger Pulley (like the one Steeda offers) spins at a faster rate than a larger pulley, effectively giving you a huge power boost by making your supercharger's rotors spin faster.

I, uh, threw my GT500 into a ditch and/or my neighbor's fence...

Needless to say, we are shocked by this turn of events. Now invest in some GT5000 suspension gear, especially upper and lower control arms and a GT500 Panhard Rod, both of which will help keep your rear from breaking loose when you get on the throttle. Maybe add in an even bigger brake kit so that you can stop before that ditch/white picket fence of choice.

Will any of this stuff void my warranty?

All warranty decisions are up to your dealership. If they think that a particular aftermarket part caused the failure in question, then they can refuse your warranty. Any type of PCM tuning will, sadly, instantly void your Ford Powertrain warranty. Our advice is to talk to your service advisor about possible upgrades and their policies regarding GT500 performance parts.
