What's wrong with the pricing of the 624 hp supercharger kit from Ford Racing? Find out inside.

A new kit from Ford Racing promises to raise the power output of the 2011 Ford Mustang GT by 51 percent.  With a 2.3-liter twin-screw supercharger, the 5.0-liter 4v TiVCT V8 engine is tuned to deliver 624 horsepower (465 kW, 633 PS) and up to 536 ft-lb (726 Nm) of torque.

For $7,500, customers will get supercharger, along with an air-to-liquid intercooler, drive belt, intake manifold, and robust new fuel injectors.  Also included is a ProCal engine calibration tool.  For an extra $600 the normally black kit can be purchased in polished chrome.

However, we are not sure why anybody would actually want to buy this package.  According to their website, Ford Racing offers a 750 horsepower (559 kW, 760 PS) polished supercharger kit for the 2011 Mustang and a full $900 less than the black kit.  That kit provides 17 psi boost over the weaker kit's 9 psi.  It instead uses a 2.9-liter Twin Screw supercharger.

More power, for less money.  We're pretty sure which Mustang package we'd pick.
