Hooking up Horsepower
This ’10 Challenger acquired twin turbos and a longer stroke, which combined developed 640 rwhp. A 42% increase in power means one thing: a stronger clutch would be necessary to transmit the power.
The experts tell us that of modern-day muscle cars the Challenger holds closest to the idea of the original by delivering blistering straight-line speed, immense road presence and a ride comfortable enough to cruise the boulevards all day.
The ’10 Dodge Challenger generates just less than 450 hp. But things change when the 5.7L (345 ci) engine is stroked to 394 ci and twin turbochargers are added. Recently, Tim Matherley of MV Performance in Winder, Georgia, did just that. When work was completed, the Challenger made 640 rwhp at 5,900 rpm and generated 720 ft-lbs torque. To cope with the 42% increase in power, Tim selected Ram’s Force 10.5 dual-disc and aluminum flywheel assembly to replace the original 9.5-inch OEM dual-disc arrangement. To understand and master the process, we invite you to follow Tim’s steps and learn how to perform a clutch upgrade.
First, the driveshaft, exhaust system and starter motor were removed. The slave assembly and part of the two-piece shifter stick mechanism were disconnected. A transmission jack was secured to the six-speed manual Tremec 6060 gearbox. Then the six fasteners from the cross member and eight from around the bell housing were disconnected, allowing for the transmission’s removal.
