Justin: Hey Justin with AmericanMuscle.com here with a Stage 1 Power Pack Bolt-on Build-up
for all 2007 to 2009 GT500's. 2007 marked the 40th anniversary of the original GT500,
so Ford and Shelby decided to do what they do best, and give this car enough horsepower
and aggressive styling to make it worthy of the GT500 badge. Just because the GT500's
are the baddest of the bad in factory form, doesn't make them immune to the typical Mustang
owner's treatment, which is: how do we make this thing faster? So, that's the goal here
with these Power Packs. Now if you want to check out more Bolt-on Build-ups for your
ride, you can subscribe to our YouTube channel by clicking on the link below if you haven't
done so already. We already knocked out our baseline run with the 2008 GT500 here, so
let's get into the mods that make up our Power Pack. This Power Pack consists of two relatively
simple parts that a majority of our customers and Mustang owners turn to when they first
start modding, GT500 owners included. And there's a reason for that, they're both extremely
easy to install, even for the most novice mechanics out there, and best of all, they
get results. The first part, which I just finished up installing is JLT's carbon fiber
Big Air Intake, available for all 2007 to 2009 GT500's. Again, a very simple mod, very
easy to install, but a very important mod when you do start working on these cars with
the positive displacement blowers, like the '08 GT500 here. A lot of people think that
the easiest way to make more power and boost on supercharged engine is to throw a smaller
pulley on it, and while that's not a bad idea, did you know you can actually pick up a lot
more power and possibly even an extra pound or two of boost simply by throwing on a massive
cold air intake like the JLT here. You're not only allowing the engine to breathe a
lot easier, which is going to increase your superchargers efficiency, but you're also
increasing the flow capacity of the motor itself. So basically when you do throw a smaller
pulley on down the road and really start spinning that blower up, the motor isn't going to get
choked out by the less efficient factory intake. In addition to that, the JLT just looks awesome.
The carbon fiber construction will look great under the hood, and will definitely get you
a few style points while you're at it. On top that, like I said earlier, a very install.
It will take you maybe an hour tops. Now if you want to learn more about this intake and
hear what other GT500 owners are saying about it, just click the link below to head back
to the product page at AmericanMuscle.com if you're not there already. The JLT does
boast one of the largest MAF housings available on the market today at 127mm, which is basically
going to allow your blown 5.4 liter to devour massive amounts of air. However, because of
this, a custom tune is required, so I'm going to call my buddy Mike J. in from Bama Performance
to talk a little bit more about the second part of our Power Pack. I just finished up
with the install of the JLT, as you can see. How is this going to affect your tune? Mike:
Well obviously the JLT is going to push in a lot more air, and any time you're pushing
in more air, you really got to be conscious of your fuel-air ratio. So the first thing
we're going to look at is fuel adjustment, spark adjustment, to get that right. We'll
load everything up using the Bama SCT Tuner, get this thing loaded up and make some more
hits on it. Justin: I'm going to hop in, do another pull, see what kinds of gains we're
looking at. Justin: Baseline numbers with our 2008 GT500 gave us 434 horsepower and
432 pound-feet of torque at the rear wheels. At the end of the Stage 1 Power Pack, our
car was now making 508 horsepower and 479 pound-feet of torque, giving us a peak gain
of 74 horsepower over our baseline numbers, and gains of 56 horsepower and 64 pound-feet
of torque throughout the curve. Well with only two pretty basic mods and about an hour
or two worth of our time, we gave our already potent '08 GT500 a serious bump in power that
even the most jaded gear head would be happy with. Now that will do it for the Stage 1
Power Pack Bolt-on Build-up with the '07 to '09 GT500. You have to check out our other
Bolt-on Build-ups for the '07 to '09 GT500's where we really increase the power and start
talking about some more serious mods. Don't forget to subscribe to our YouTube channel
