hey everyone, justin with americanmuscle.com,and this is our powerpack bolt-on build up for all 05-09 mustang gts. the goal of thispower pack is to take our stock 07 gt, and combine it with some of our most popular performancebolt ons. the result will be twofold, we're going to add more horsepower and torque atthe rear wheels, while really cranking up the volume on our 4.6l to make our gt soundas tough as it looks. currently, our 2007
2008 super snake mustang for sale, gt is bone-stock performance wise, so let'sget it outside and hear how that stock exhaust sounds, and then get it back on the dyno toget some baseline numbers down. so our stock dyno run gave us 259 horsepower, and 289 ft/lbsof torque. alright, now that we've got some baseline numbers from our 07 gt, we're goingto talk to mike wilson, our lead calibrator
from bama performance, to walk us throughsome of the mods we're going to do today. mike, what have you got up first for us? mike:well, first we're going to install this airaid race cold air intake which is a great firstmod, it's going to increase air flow, give us a big gain in horsepower and torque, andhas a really easy install. justin: alright mike, i know with some cold air intake systemsyou need a tune, sometimes you don't, what's up with this airaid? mike: the airaid racecold air intake does require a tune, because of that, we're going to install a bama performance93 octane race tune, which is going to increase our horsepower and torque by adjusting thespark curves, fuel map, the drive by wire calibration, really improves the horsepowerand torque. justin: that's awesome man, i
know in addition to that we're also goingto throw in a pypes off road x-pipe, and also a pypes axleback system as well, what canwe expect from that? mike: that's also going to free up the exhaust flow which is goingto give us more horsepower and torque, and it's going to sound incredible compared toyour stock exhaust. justin: our second dyno run with all the performance parts installedon our 2007 gt gave us 293 horsepower, and 309 ft/lbs of torque, making for a peak gainof 35 horsepower, and gains of 36 horsepower and 29 ft/lbs of torque throughout the curve.alright mike, that's awesome, what do you think of the results? mike: exactly what iexpected. we're putting the cold air kit on, the exhaust, and wrapping it all up with acustom tune, we're definitely going to feel
a big difference in the street. justin: awesome.well, with that said, we're going to get our 07 gt back on the streets, because i'm dyingto hear how this pypes combination is going to sound versus our stock exhaust so thanksagain, mike. mike: any time. justin: now that we have our 07 gt out on the road we finallyget to see these mods in action and i've got to tell you they're really doing their job.our gt just pulls so much harder on the upper
rpm range, which means our car is breathinga whole heck of a lot easier. the best part is, they installed easily in about 2 hours,with simple hand tools and a few floor jacks. be sure to check out our other 05-09 mustanggt bolt on build ups, where we work on our appearance, help get our gt off the line,and make it handle a little better.
