Justin: Hey, everyone. I'm Justin with AmericanMuscle.com, and this is our Power Pack Bolt-on Build-up series for all '99 to '04 Mustang GTs. With this Power Pack, we put together some products that we feel are great first-time mods and that would give any '99 to '04 Mustang GT a serious boost in power. So, we're going to grab a quick baseline run, and then hand our GT over to the crew so they can get started installing our Power Pack. Hey, what's going on, Mike?
Mike: Hey, man, nothing. Just finished the installation of our mods, and we're about to make another dyno run.
Justin: Very nice. Yeah, it looks great under here. What have you got going on under the hood?
Mike: Well, first we installed an AIRAID cold air intake kit that comes with a high-flow reusable air filter, so you never have to replace it. The AIRAID's going to increase airflow to the engine to allow it to breathe better and make more horsepower, and it's also going to help on fuel efficiency.
Justin: Yeah, if you could stay off the pedal, right?
Justin: I see we also got the BBK installed. What's up with that?
Mike: This is the one-piece throttle intake that incorporates a throttle body and the plenum. That way, you can have a bigger throttle body and not worry about restricting the airflow with the factory plenum.
Justin: Mike, I know, with this generation and with these mods, we shouldn't really need a tune, right?
Mike: Right. They don't require a tune, but we are going to install a BAMA Performance custom tune just to kind of tie everything together. Especially being an automatic, it's going to help with our shift permanence, our shift points, and the overall performance package.
Justin: That's awesome, man. Now, I know, in conjunction with these mods, we also have the Pypes off-road X-pipe going on, along with that Flowmaster American Thunder Series cat-back as well. What kind of numbers are you expecting from all these mods?
Mike: We should expect to see around 20 to 25 horsepower to the tire.
Justin: Sounds good to me, man. You ready to do another run?
Mike: Absolutely. Let's do it.
Justin: All right.
So, our baseline run on our automatic 2000 GT gave us 222 horsepower and 260 foot-pounds of torque. With our Power Pack installed, we made 249 horsepower and 295 foot-pounds of torque, giving us a peak gain of 27 horsepower over our baseline numbers, and gains of 35 horsepower and 54 foot-pounds of torque throughout the curve.
So, as you can see, we just finished up our second Dyno run, and we're definitely happy with the results. The best part is, all these mods are installed easily in just a few hours using basic hand tools. Now, let's get our GT off the Dynojet and onto the streets so we can hear that Flowmaster in action and see what these mods did for our motor.
All right, now that we got our GT out of the shop and onto the streets, and been able to put it through its paces a little bit, it's easy to see why these bolt-ons are such a popular first choice with so many Mustang owners out there, especially these '99 to '04s. Those bolt-ons really woke up our two-valve motor, especially paired with that BAMA tune, which has really firmed up our shifts as well.
So, be sure to check out some of our other '99 to '04 Bolt-on Build-ups, where we improve our handling, work on our acceleration, and dress up our GT a little bit.
