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.

  1. Hmmm... I wonder if this is the basis of the engine planned for the new 2013 Viper. 8.7-liters seems a bit ridiculous but this new unit would be so sweet.

    Bad stuff?

     
  2. @Damien, I doubt it. An engine built for drag racing is high-strung, tuned for power more than longevity.

    I've got a feeling you won't be disappointed when Dodge (or SRT) finally releases the numbers on the new Viper.

  3. Of course that is true. But the basic aluminum block and some of the other hardware could be used could it not?

  4. @Damien, yes, Dodge will probably use the same block (with a slightly larger bore) and heads.

  5. considering the size of the planned engine on the new gen Viper i can see it just being able to make a run to the shops and back on a single tank of gas while it chews through fuel and tyres. Not a fan of oversized engines, as smaller blocks if made properly are for more effiecient, powerful smooth and noisy. Take the previous 6.3 v8 from AMG as an example. the sound was pure mechanical sex. the latest tt5.5 jsut released will be just as wonderful.
