Are eight cylinders not enough...and twelve way too many?

Then you're the kind of Mopar competitor who'll want one of their new V10 Competition Crate Engines in your race car...or the Performance Upgrade Kit for your existing Gen III V10-powered Viper.

Making its debut at this year's SEMA Show:  Mopar's 800 horsepower V10 Competition Series engine, part number P5155872,designed specifically for drag racing. Hand-assembled to exacting standards by race engine builders, the Competition Series V10 features an aluminum block with aluminum cylinder heads.

Designed for the rigors of drag racing and pulling 695 lb. ft. of torque with an operating range of up to 7,000 rpm, these race-calibrated engines include a forged steel crankshaft, forged steel connecting rods and forged aluminum pistons with a compression ratio of 12.5:1.

All rotating components have been balanced for maximum performance at the track.

The Competition Series engine includes a JTEC controller with race calibration and engine harness. Designed specifically for drag racing, future applications include an off-road and road-race version.

If you're looking for up to 150 more horsepower from your Gen III Dodge Viper, you can now bolt on a Performance Upgrade Kit, part number P5156137, to your stock V10 engine. Each kit includes a pair of aluminum cylinder heads (machined to fit the Gen III block), a custom upper intake manifold with a larger throttle body, fuel rails and injectors. The stock engine controller will have to be re-flashed. All necessary hardware and gaskets are included.

With the Performance Upgrade Kit, you'll see up to 650 horsepower from your existing engine, while still maintaining excellent low-end driveability.
