AI caption · Photo 0 of 5000

This is a photograph of a car show display placard (not a factory reference document) for a 2004 Dodge Viper built and tuned by JMS Chip & Performance in partnership with SCT (whose slogan 'More Power! Less Fuel!' appears at the top). The placard states the car produces 1141 horsepower and 1083 lb-ft of torque. Listed modifications include a stroked and bored 522 cubic-inch Viper engine with forged pistons and rods, ported heads, a custom-grind camshaft, and 11:1 compression. Forced induction is provided by a 9 PSI intercooled Paxton Novi 2000 supercharger, supplemented by a Snow Performance Stage II methanol/water injection kit. Additional equipment includes Asanti AF114 wheels and a Corsa exhaust. The placard features photos of the silver Viper convertible and two engine-bay shots showing the blue 'VIPER' intake plenum. The JMS logo and website (www.jmschip.com) appear at the bottom. A reader learns the full build specification of this SEMA/show-style demonstration vehicle. Note: although uploaded to a 1998 Ford Crown Victoria gallery, the document itself pertains exclusively to a 2004 Dodge Viper.

This document covers 2004, which may differ from this 1998 Ford Crown Victoria.
