Review & Install Video
I’m Justin with AmericanMuscle.com, and this is our acceleration pack bolt on build up for all 99-04 Mustang GTs. The focus of this pack is of course acceleration, but in order to accelerate faster you need traction, and lots of it. That’s why the majority of the parts used for our build today are focused on getting us off the line much quicker, ultimately resulting in faster acceleration. But before we go over all the parts we have in store for our 2000 GT here, let’s get it out of the shop and do a quick 0-60 baseline run, just to see where we stand now. Alright, before we go installing all of our parts for the acceleration pack, we’re going to do a baseline 0-60 run, using our iTSX wireless tuner and my iPad here, just to see where the car stands now, so hit start and here we go. Alright so it looks like we just clicked off a 6.66 0-60 time with our automatic 2000 GT, which is pretty average for this model car. Now we’re going to take our car back into the shop, talk a little bit more about some of the parts we have in store, and get them installed. Since traction is the theme of the day, what better way to get more of it, than by using a set of these NITTO NT555R Drag Radials, those large tread blocks paired with that real soft compound is going to give us a ton of grip both on the street and at the strip, and should really help our GT get off the line. To further help our GT hook we decided to go with some vital suspension components from QA1, starting with these box style rear lower control arms, these bars are a variation of the classic traction bar design, and basically help keep the rear axle from moving around under load, and especially on hard launches, eliminating any excessive wheel hop. We also decided to go with a set of these QA1 adjustable rear upper control arms, that are fully adjustable while still on the car. These are going to be key to adjusting our pinion angle which is not only important for traction, but also for driveline smoothness. These are really going to help firm up the rear end of the car, and eliminate any side to side sloppiness or wiggle, making the car track a lot straighter, and just making for an overall better driving experience. Moving away from our traction and getting into another big contributing factor to our acceleration, that’s right our gearing. From the factory, our automatic 2000 GT came with 3.27 gears, which is pretty weak for acceleration. That’s where these Ford Racing 4.10 gears come into play, simply put, that shorter gear ratio is going to help our car accelerate faster. Quite frankly, I’m quite anxious to see how it’s going to wake up our 2 valve motor. So now that you know what we have in store for our GT, we’re going to hand the car over to the crew and get everything installed, after they’re all done we’re going to take our GT back out on the street, just to see how it behaves on the road, and to see if we’ve improved on our 0-60 time. Alright so we’re out here on the street with our 2000 GT, we just had the acceleration pack installed by the guys back at the shop, and we’re just cruising, I mean the car is very mild mannered, we’re in overdrive, you’d never be able to tell there’s gears in the car, until you do a little squeeze on the throttle, and man does it go. It goes, it goes, and it hooks hard too. I mean we didn’t even have a chance to heat cycle the tires there and it just dead hooked on the street. Car is a little stiffer in the rear, that’s attributed to the stiffer bushings in both the QA1 lower and upper control arms, but that’s going to be a good thing, that’s going to help keep the car straight, going down the track, it’s also going to reduce our wheel hop as well, and overall just improve our acceleration. So now we’ve had the chance to drive the car around on the street a little bit, see how it reacts in everyday situations, we’re going to put it to the ultimate test, get it back to the shop, do a hard launch, and see if these parts work in lowering our 0-60 time. Alright, so we just finished up our second 0-60 run, and we just clicked off a 5.09 second 0-60, that’s over half a second off our baseline number, so it’s easy to see our acceleration pack is doing its job, and I’ve got to admit, those radials definitely helped us hook on the pavement. So that does it for the acceleration pack, be sure to check out our other 99-04 bolt on build ups where we make our GT handle a bit better, we give it some more power, and dress it up a little bit.
