Up until now most of the highly modified 2011 Mustangs we’ve seen have used some sort of power adder, from twin-screw and centrifugal superchargers to turbochargers to nitrous. The results have been impressive, with an otherwise stock supercharged Mustang netting a low 11 second 1/4 mile pass, and more highly modified cars achieving 9 second and even 8 second 1/4 mile runs.
But how far can the 2011 Mustang go naturally aspirated? The guys over at JPC Racing of Millersville, MD were determined to be one of the first to find out, and they fitted a 2011 Mustang with a plethora of bolt-on parts including their own long tube headers, off-road x-pipe, Stage 1 ported heads and Stage 1 N/A cams. A Bassani axle-back exhaust system, Ford Racing Boss 302R intake manifold and JLT cold air intake system were also installed, with a custom JPC Racing tune done through a DiabloSport Trinity. The result was more than 500 rwhp – 507.7 to be exact – the first for a naturally aspirated 2011+ Mustang. You can watch a dyno run of the car below.
