X charger.... Go X charger, I've had mine for a month and it's definitely fun to drive, I haven't had the priviledge of running a GT yet, but, I have a 350Z under my belt, I surprized him when I told him it is a V6. they don't look hard to install, i had mine done by a local dyno, so they could tune with dyno, went to Missouri for a wedding and wanted to make sure it was installed and dyno'd for Mustang Week in myrtle beach. end result 293 rwhp and 319 rwtq, eventually a gear. more then enough to take a stock GT, they dyno at 255-260 rwhp, remember 300 hp is at the flywheel the subtract 15% that is a rough est. of HP |
