American tuners SpeedFactory claim to have set a new record with the SpeedFactory 426 Charger.  The car sprinted to the quarter-mile mark at the South Georgia Motorsports Park in 9.453 seconds at 145.38 mph.

The company claims this time to be the fastest ever for a car riding on a Chrysler-built LX/LC platform, including the recently-produced Chrysler 300Cs, Dodge Challenger, Charger, or Magnum.

Based on a 2006 Charger, the tuner car uses a 426 HEMI with V7 YSI supercharger increasing power to 900 horsepower.  With no interior, the car weighs about 3,750 lbs (1700 kg).

"With the introduction of the Drag Pack Challengers, we knew that records would be broken, and to achieve this with a modified stock vehicle that still utilizes the factory components makes this even more exciting to us and our partners," said Mark Brucks, general manager for SpeedFactory.  "We believe there is more that can be done to produce even faster times."
