2010 Dodge Viper ACR-X on the dyno - Click above to watch the video after the jump
There's something about glowing hot metal that gets our hearts racing here at Autoblog. Whether it's disc brakes on a racing prototype during an endurance night race or an exhaust manifold at redline during dyno testing, there's something about metal resisting the forces of incredible heat that appeals to the gearhead in us. That's why we took particular interest in this video of the new 2010 Viper ACR-X that shows Dodge's engineers going through final testing of its 8.4-liter V10.
Because it's built for the track and not the street, the ACR-X gets a few tweaks compared to the stock Viper V10. Gone are the catalytic converters and in go forged pistons, a modified calibration and long tube headers good for 640 horsepower and 605 lb-ft torque. Those headers not only look fantastic when the engine is off, they glow bright orange when the V10 is strapped to the engine dyno and revved to redline for sustained periods. You can see both the Viper ACR-X in action and the dyno tests in the video after the jump.
