American aftermarket tuners SpeedFactory claims to have set a new record with its SpeedFactory 426 Charger. The car covered the quarter-mile in just 9.453 seconds at 145.38 mph.

The company is saying that this time is the fastest ever for a car riding on a Chrysler-built LX/LC platform, including the recently-produced Chrysler 300Cs, Dodge Challenger and the Charger.

Based on a 2006 model Charger, the tuner car is powered by a 426 HEMI with a V7 YSI supercharger that’s boosted power to 900 horsepower. Even with the interior stripped out, the car still weighs around 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 utilises the factory components makes this even more exciting to us and our partners,” said Mark Brucks, big boss at SpeedFactory.  “We believe there is more that can be done to produce even faster times.”
