Enthusiasts will tell you there are three types of shifting: granny, speed, and power. Simply stated, if you shift aggressively but lift off the gas, you’re speed shifting. If you ram the gears with the throttle held on the mat, you’re powershifting. Granny shifting is not worth talking about. In any case, you want to complete the shift as quickly as possible and with as little flare in the rpm. Timing is everything. Practice makes perfect. If you’re uncomfortable powershifting, try it at a lower rpm until your shifting is seamless.
Throughout the ’80s, ’90s, and the first decade of the new millennia, Dodge was—to put it bluntly—bad at math. Ford and Chevy (and Pontiac in earlier years) adeptly applied the age-old hot rodder’s calculus of horsepower divided by weight divided by MSRP. This performance quotient resulted in a hot horsepower battle that saw almost yearly changes in the top-dog spot, and an upward spiral in the performance index as a whole. Except in Chrysler-built products.
Once in Fourth, all that’s left is to ride it out. With 3.73 and a few mods, it may be necessary to upshift one more time into Fifth. This always makes us nervous because we don’t want to mess up the last shift, plus Fifth gear can be fragile and we don’t want to break the trans. Our test car did not require shifting into Fifth, but we’ve had to do so in 2011-2014 5.0 Mustangs.
Shelby American is a name that is famous for power and performance in the automotive world thanks to its long historic racing pedigree in the early 1960s to present. Many Mustangs have rolled out of the Shelby’s doors to conquer both the street and track and for 2015, they are pulling out the stops with their all-new S550 Shelby GT Mustang. The S550 Mustang also features a fully independent rear suspension on its entire lineup, which has all corner carving enthusiasts excited.
