Illustration for article titled Speedfactory Cars Blows SRT8 Challenger, Sees 495 Rear-Wheel HP

The peaches over at Speedfactory Cars out in Georgia have employed the magic of forced induction to achieve 495 HP at the rear wheels of a Dodge Challenger SRT8. Using a centrifugal supercharger sending boost through an air-to-water intercooler, Speedfactory's dyno graph also shows maximum torque output of about 451 ft-lbs. While official figures aren't yet available — and we're not entirely sure which of the packages offered they've got running on this SRT8 — the commonly accepted 20% power loss from crank to rear wheels means this Challenger should be pounding out right around 600 HP at the crank. We'll take two. [Speedfactory Cars via LX Forums]
