Hennessey Performance upgrades the Ford Mustang Boss 302

Wed, 31 Aug 2011 00:00:00 -0700

The tuner guys at Hennessey Performance took the Ford Mustang Boss 302 behind their curtain, plopped a supercharger on top--among other things--and headed to the drag strip.

The outcome? Hennessey says 11.9 seconds at 124 mph for the quarter-mile--and that's with a 0-to-60-mph time at a Porsche-like 3.9 seconds.

The HPE650 upgrade, which is the middle package, ups power to 650 hp. It comes with the roots-style TVS2300 supercharger, a high-flow breathing system, a strut tower brace and Hennessey's HPE engine-management calibration. It's not inexpensive--the HPE650 will set you back $15,995 with installation.

The beginner kit, the HPE492, gets cold-air induction, performance headers, a high-flow exhaust and the company's engine-management calibration for $3,995, or $5,495 installed.

For the truly brave, the company offers an even more powerful package called the HPE700, making--you guessed it--700 hp. The top package gets the same supercharger as the HPE650 with a pulley upgrade, intercooler, high-flow breathing system, fuel-system upgrade, strut tower brace and side exhaust. The $19,995 cost includes installation, gaskets and fluids, Hennessey badges and dyno tuning.

Optional extras on all of the kits include a carbon-fiber splitter, wheel and tire packages, more suspension and handling upgrades, a one-piece driveshaft upgrade, a heavy-duty clutch upgrade, brake upgrades and other bits and pieces.
