      Video Review & Installation

      JUSTIN: Hey, I'm Justin with AmericanMuscle.com, and this is our powerpack Bolt-On Build-Up for all 94-98 Mustang GTs. Now before we get started, we're well aware of the fact that the 94-95 GTs came equipped with the 5.0 motor before eventually being replaced by the modular 4-6 in 1996. So, with that said, all the parts used here on our '98 today, will not apply to those earlier years, but the idea remains the same, to increase the power. So that's why we put together a pack of parts that should help our GT breathe a lot easier, in turn making for some more horsepower and torque, all while making for one mean exhaust note. Now, before we get started on our car, we need to grab a quick baseline number, and then hand that over to the crew to get everything installed.JUSTIN: Hey Mike, looks like the guys just finished up working on the car here, you want to walk us through a few of these mods?MIKE: Absolutely.JUSTIN: Well, I know we have a trio of parts from SR Performance under the hood, starting with their Cold-Air Intake system. What's up with that?MIKE: It's a very budget-friendly piece and it's going to give us the increase in airflow we're looking for, which is going to equate to more horsepower.JUSTIN: Speaking of increased airflow, we also went for the 70mm Throttle Body, as well as that Upper Intake Plenum from SR Performance, now these are big 2-valve mods, why are they so important?MIKE: Again, more airflow is going to create more horsepower. You can put a larger Throttle-Body on, but with the stock Plenum, you're not taking full effect of that larger opening, put the Throttle Body on along with the Plenum, get the total package.JUSTIN: Well, it looks like we definitely took intake side of things. As for the exhaust, I know we went with Pypes Off-Road X-Pipe, along with their Violator Series CatBack. Now, besides really cranking up the volume on our 4.6 L, what are some of the other benefits?MIKE: Well we're definitely getting a louder exhaust note because we deleted the catalytic converters, besides the louder sound, we're going to increase the airflow by not going with the factory restrictive sized exhaust pipe, and out back those 3.5" chrome tips are really going to look good.JUSTIN: Absolutely man, well I know we tweaked a lot of stuff here on our 2-valve motor, it's going to be seeing a lot more air than it did before, do we need a tune with these mods?MIKE: These parts don't necessarily require a tune, but we're going to put on one of our Bama performance tunes to modify the fuels, the spark, the speed limiters, rev-limiters, and the cooling fan temps to help make this the total package.JUSTIN: Well, I can't wait to see what this combination's going to put down. You ready to make another another pool?MIKE: Absolutely, let's do it.JUSTIN: So our baseline run with our '98 GT gave us 185 horsepower and 252 ft/lbs of torque. With our powerpack installed, we were able to put down 210 and 283 ft/lbs of torque, making for a peak horsepower gain of 25 over our baseline numbers, and gains of 26 horsepower and 34 ft/lbs of torque throughout the curve. Well, now that we have the numbers we're looking for, it's time to get our GT off of the dyno and out onto the streets so we can have a little fun with some of that new-found power, and, honestly, I'm pretty excited to see that Pypes combination in action.JUSTIN: Alright, so we're out on the road here in our '98 GT with the powerpack installed, and I just want you to listen to how sweet that exhaust sounds, man. I might wrap it up for you real quick. That sounds incredible! I've driven a lot of Mustangs, don't get me wrong I mean that's my job, and quite honestly, this is probably one of the better sounding setups I've heard in long time, man. It doesn't sound raspy at all I mean, you're getting rid of the cats, usually it's a rasp machine, but this thing sounds amazing, but enough with the sound already, this is a powerpack, so let's see how we feel when we actually get into it a little bit, shall we? Wind second out a little bit. The car definitely pulls a lot harder in the upper RPM range, and a lot of that can be attributed to how well we're making the car breathe now. I mean, we've got everything working for us, from the intake all the way back to the exhaust. This thing is definitely flowing a lot more air, and it shows whenever you get on the throttle. All in all, I think the powerpack is a success here in our '98 GT, we made a bunch of power, and that exhaust note says it all, man. Well that wraps it up, so be sure to check out some of our other Bolt-On Build-Ups for the 94-98 GT. We're going to work on the appearance a little bit, and make our car handle like it's on rails.

      Improve ET's and low end torque. Are you looking to get more low end grunt off the line and lower ET's at the same time? Then look no further than installing a set of steeper gears in your Pony. Ford Racing Ring and Pinion Gears are perfect for street, road, or race use.

      Superior Quality. These Ford Racing 4.10 Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion.

      Application. This Ford Racing Ring and Pinion Gear set will fit 11-14 Mustang GTs and 11-12 Shelby GT500s. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

      Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.

      Technical Note. Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.
