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.
