Hey, I'm Justin with AmericanMuscle.com, and this is our power pack Bolt-On Build-Up for all 2011 and newer Mustang GTs. Power, it's a simple thing really, what puts a smile on our face every time we bury the throttle. It's why we a Mustang instead of a Prius. Never before has there been a factory GT that has made more power than these newer Coyote Mustangs. Now even though this amazing 5.0 motor produces over 400 horsepower at the crank, eventually we get used to it, and it's at that point that we begin our search for more. That's what this power pack is all about. We're gonna be installing some of the bolt-on basics and then using our Dyno jet here, to see what kind of improvements we made. So, enough with the talking already, let's get a quick baseline number down, and then get to work installing our parts. Hey Mike, I know the guys just finished up installing the parts on our 11 here. Looks like we got some great parts that should help our Coyote motor breathe a little easier Let's work from front to back. Starting with that Airaid, now what makes those a little bit better than the stock airbox?
MIKE: Well, it's got a high-flow reusable air filter that's gonna allow more air to enter the engine. The closed Airbox blocks all the heat from the engine from getting into the motor, and the increased size of the intake tube again, is gonna allow more air to get into the motor, allow it to breathe better, make more power.
JUSTIN: Awesome man, speaking of allowing more air into the motor, we also went with 85mm BBK throttle body, what are some of the benefits of going with that?
MIKE: Well, while it doesn't pack the biggest punch in horsepower, it's a great complementary mod, and thanks to the pre-installed electronics from BBK, makes it a very simple install.
JUSTIN: Now let's move onto the business side of things, I know we got a couple of parts from Magnaflow for the exhaust starting with their TrueX X-pipe. Explain, if you will, the benefits of using an off-road X- or H-pipe, and what can we expect?
MIKE: Well, you're gonna eliminate the catalytic converters, which is gonna increase airflow, and we've got the X-Pipe, which is gonna do a real good job of scavenging the exhaust, and again, making more horsepower. Out the back, we've installed the Magnaflow street axle-back system which is an aggressive sounds, but it's not too loud, and we're not gonna have any of the drum.
JUSTIN: Now, I know each one of these parts individually does not require a tune, but you really stress the importance of kind've bringing them all together with one of your custom Bama tunes. Why is that?
MIKE: Well, with the Bama tune, we take all the modifications into effect when we build the tune for the car. While the Airaid doesn't require a tune, because of the modular Venturi insert, we've removed the insert to increase the airflow, and increase the horsepower, but it also wraps everything else together. The drive-by-wire, calibration for the pedal, the transmission calibration, a bunch of other things that we do, kind of wrap the whole package together.
JUSTIN: Well, there's only one more thing to do, I guess, right, and see what kind've power it makes?
MIKE: Absolutely.
JUSTIN: Let's do it. So our baseline run with our automatic 2011 GT gave us 337 horsepower, and 325 ft/lbs of torque. With our power pack installed, we put down 381 horsepower, and 359 ft/lbs of torque, making for a peak horsepower gain of 44 over our baseline numbers, and gains of 44 horsepower, and 51 ft/lbs of torque throughout the curve. Now that we know the power's really been increased, I'm gonna get to work on strapping the car, so I can take it out on the streets, and have a little fun. Alright, well, what better way to start off the powerpack with the 2011 GT with a nice big, smoky burnout, huh? Well, I tell you what, man, the exhaust sounds great already, definitely more grunt than the stock exhaust. We've got a straightaway coming up here, so let's get around this bend, hammer on it, and see if this power pack's doing it's job, shall we? So, a solid chirp in 3rd gear, the car winds out way harder than it did before. Those shift points have definitely been raised a few hundred rpm, and the car pulls like a bat out of hell, man, it's awesome! Like I said about the exhaust, Magnaflow did a great job at creating a street-series, which is a nice balance between that classic muscle sound, but also, you know, keeps it tame. You can still cart your Mom around town, and she's not gonna be complaining the time, my car is too loud. So, I love it man, sounds great. Now of course we've got the Cold-Air installed along with the throttle body, parts that, you're probably not gonna notice are installed when they're working in conjunction with everything else, but we've seen the results on the dyno, we know they're doing their job, and that's just the whole point of the powerpack, man. We got a bunch of parts working together for us, to one common goal, of making this thing really rip, and boy does it, as you just saw. So, that's it for our powerpack for the 2011 GT. I'm gonna go incinerate some more tires, but in the meantime, be sure to check out some of our other 2011 and up Bolt-On Build-Ups, where we make the car look a little bit better, and make it handle like it's on rails.
