If you’ve spent any time at all hanging around the various online forums, you’ve seen the obligatory, Which manual transmission should I use? post. Most often, the poster wants a street/strip setup; something that will be easy to drive on the street but yet could withstand a few launches at the local dragstrip. We all want that, right? We all want something between the T-5 that’s in Dad’s ’93 Mustang GT and the Jerico that we see on YouTube getting the absolute snot beat out of it at the dragstrip.

Speed is addictive, and we’re always striving to go quicker and faster, and it seems to be getting easier in the modern world. Take, for example, the ‘07 Mustang GT featured on these pages. Last year, we added a Ford Racing Performance Parts supercharger kit, Steeda 10-rib pulley upgrade, custom tuning (Diablo-Sport), and a set of drag radials. That led us down a path of mid-11s with a best of 11.49 at 119 mph (with 479 rwhp through the stock automatic).
