If you think the stock Viper is a brutal machine, imagine the Dodge sports car fitted with a Mopar-upgraded 800HP V10 like the one unveiled at the SEMA show.
The new engine, codenamed P5155872 Performance Series V10, has been developed especially for drag racing. It features an aluminum block and aluminum cylinder heads, forged steel crankshaft with forged steel connecting rods and forged aluminum pistons with a high compression ratio of 12.5:1.
If you own a Viper and want more grunt but don’t plan to drag race, Mopar does have a solution for you: it’s the P5156137 Performance Kit that consists of aluminum cylinder heads machined to fit the Gen-III block, a custom upper intake manifold with larger throttle body, fuel rails and injectors, and a re-flashed engine controller.
This bolt on performance kit lifts the V10’s output to 650 ponies, 150HP more than the standard version while still maintaining the stock engine’s drivability.
Next in line on Mopar’s catalogue is a new crate engine, a 590HP version of the Gen III 426 Hemi V8. The P5156139 High Output V8 is 100 lbs lighter thanks to an aluminum block that replaces the stock cast iron one. It also has a forged steel crankshaft, forged rods and forged aluminum pistons with an 11:1 compression ratio.
Running exclusively on premium gas with a 93 octane minimum rating, it has a more aggressive camshaft with inlet and outlet intake and exhaust lift and cylinder heads that maximize the engine’s flow characteristics.
SEMA will also see the launch of two 426 “Ready-to-Run” Mopar engine calibration kits for the High Output and the standard 426 engines respectively.
These kits include a throttle body, engine harness and engine controller with base calibration and can get your project finished quickly, although depending on specific transmission, axle ratio and tires, final tuning may be required.
Mopar has also developed a distributor front drive kit for GEN III HEMI engines. The kit includes a machined front cover, camshaft timing gear, fuel pump push rod and bolt kit. Kits are available for both pre-2009 5.7-liter and 6.1-liter engines, as well as newer 5.7-liter and 6.4-liter versions.
Last, but in no way least, is the new Dodge Challenger body shell that will be offered in a limited number complete with doors, rear deck and hood, for those seeking to build a racecar from the ground up but don’t want to use a used or damaged car.
The company stresses that these Challenger bodies have no identification numbers, therefore can only be used in racing and are not street-legal.
