Are you regretting the purchase of that V-6 powered Dodge Challenger, and wishing that it had just a bit more grunt, especially at low end? Are you tired of four-cylinder turbos showing you taillights off of every stoplight?
Get ready to spend some money then, because Mopar has a solution to your problem. Debuting at this year’s SEMA show is a 512 cubic-inch (6.4 liter), aluminum block V-10, good for an estimated 800 horsepower and 695 lb.-ft. of torque.
Mopar says the engine is designed for drag racing, which probably means that it isn’t EPA or CARB emission compliant for on-road use. Future versions calibrated for off-road racing and road-course use are also planned, so you may want to save your pennies until the best solution for your needs hits the Mopar catalog.
If you already own a third generation Dodge Viper (built from 2003-06), there’s no need to drop in a new engine for more horsepower. Mopar is also launching a Performance Upgrade Kit for third-generation Vipers at this year’s SEMA show, and it promises to boost output by 150 horsepower.
That should bring your Viper up to 650 horsepower, making it even more powerful than the 600 horsepower fourth-generation Vipers. The kit’s components bolt on, but the ECU requires a re-flash, so a service visit to your Dodge dealer is probably unavoidable.
