      Video Review & Installation

      Justin: Hey guys, Justin with here with a Stage 1 Power Pack Bolt-On Build-Up for all 2013 and 2014 Shelby GT500s. Now these cars, the 2013 and 2014 Shelbys represent just how far we've come, in the last 50 years in the muscle car world. Beautifully aggressive modern styling, technology and creature comforts that would rob almost luxury cars, and oh yeah, by the way, a 200 mile an hour plus top speed courtesy of one of the craziest power plants ever to grace a production car's engine bay. With all of that said, and with the 662 crank horsepower that these cars come with from the factory, can you believe there's still people out there who are not satisfied? Well, those are my kind of people, and these power packs are for those of you who crave a little more. Now if you want to check out more of our Bolt-on Build-ups for your Mustang, whether it's a V6, a GT, or a GT500, you have to subscribe to our YouTube Channel. We already grabbed the baseline number for our 2014 GT500 behind me, so let's get to work with the first stage of our Power Pack. We're going to keep things very simple with this Power Pack and go with 2 basic mods that are extremely easy to install, and best of all, get some very good results. The first of which is the JLT Big Air Carbon Fiber Cold Air Intake here, which is designed to fit all 2010 through 2014 GT500s. A couple of things I like about this intake. On the surface, the JLT just looks great visually. The molded carbon fiber construction looks awesome under the hood here of our Shelby, and best of all, it should help resist some heat soak that might come along with other materials. But since this is a Power Pack, let's talk about how the JLT will help us in that regard. Now the JLT isn't called the Big Air intake for no reason. The JLT sports a massive 127 mm MAF housing which they claim is currently the largest available on the market today. The more air into the motor usually equates to more power, and that's what we're looking for here in our Power Pack. But when we dive in a little deeper and actually compare the stock GT500 intake to the JLT, you'll notice a couple of big differences. The biggest of which is this goofy resonator that is included on the factory intake. Not only does this restrict some of the airflow compared to the JLT, but it also cuts down on some of that awesome supercharger whine that we all know and love. You'll also notice that the stocker does come with this paper element non-oiled filter which isn't necessarily a bad thing as far as performance is concerned, but it does not have the ability to be cleaned and re-oiled like the JLT Power Stack Filter. So we know the JLT will be a solid upgrade for our GT500. It's going to allow more air into our Trinity motor, but because of this, we are going to need to custom tune. That leads me to the second part of our Power Pack, a custom tune courtesy of Mike J and the Bama Performance Team. Alright Mike, before we even dive in to that JLT I installed, we did notice a pretty nasty flatline with our Baseline Dyno Pull. We just figured it was the factory throttle body playing games with us. What's going on there? Mike J: Yeah, it's a pretty common occurrence on the 13-14 GT500's, for the throttle blade to actually open and close slightly under full throttle pulls, and you'll see that, and it will contribute to some of the flat spots that you saw on the Dyno Graph. Basically our tune though, we're going to fix that problem completely. Justin: That's what we like to hear, alright, good stuff. Now tell us a little bit more about tuning a monster like the GT500. Mike J: Well, for starters, we just want to do some basic pulls, so that we can get some numbers on it and see where we're at. Once we're there, we'll look at the spark tables, look at the fuel tables, add a little bit there, add a little bit here, and then all to optimize our air/fuel ratio. Try to get the most out of whatever mods we're going to add to the car. Justin: I'm guessing the JLT should help too. Mike J: Absolutely, it's going to be a big help, especially in the future Power Packs. Justin: Alright, are you all done uploading? Mike J: Yes, Sir. Justin: Hop on out, man. I'm going to do another pull and see what we're looking at our baseline run with our 2014 GT500 gave us 600 horsepower and 544 pound feet of torque. With our Stage 1 Power Pack installed, we put down 645 horsepower and 659 pound feet of torque giving us a peak gain of 45 horsepower over our baseline numbers, and curve gains of 101 horsepower and 125 pound feet of torque. I absolutely love these types of Power Packs. I mean only 2 basic mods and absolute cake to install. We picked up a ton of power and best of all, didn't even have to get our hands dirty. We hope you guys have enjoyed the Stage 1 Power Pack Bolt-On Build-Up for all 2013 and 2014 GT500's. Be sure to check out the Stage 2 and 3 Power Packs where we really go for big power, and remember, for all things Mustang keep it right here at
