After a lengthy day on the dyno, Blow-By Racing added 40 rwhp and just under 30 lb-ft of torque to a stock '10 Mustang GT with nothing more than simple bolt-on performance parts. "When the car was in stock trim, it was decent but definitely had room for improvement," Frith added. "The difference with all of the new parts is night and day. The car feels like it accelerates twice as hard."
Although the gains we've seen are not what they would have been 15 or 20 years ago, our base is leaps and bounds better than the Mustangs of yesteryear. Ford's effort to make the new Mustang a more efficient muscle car has definitely given consumers a much better starting point to build power, and the basic bolt-ons are still a great place to start.

When MM&FF rolled into Blow-By Racing, the weather was less than conducive to making power. The only upside to this was that there were only slight changes over the course of the day. When we started, the temperature around the dyno was in the mid-80s with about 50 percent humidity. As the day went on, the largest increase in temperature was less than 5 degrees, with an equal decrease in humidity. Our baseline gave us a peak number of 269.63 rwhp at 5,300 rpm with torque peaking at 296.19 lb-ft at 4,400 rpm. After steady gains all day, our series of bolt-ons resulted in a total of 309.11 rwhp at 5,500 rpm with torque peaking at 324.36 at 4,400 rpm.
