Dodge Viper Engine Receives SAE Horsepower Certification

WARRENDALE, Pa. (Sept. 19, 2005) - The Dodge Viper not only has power under the hood, but "SAE J1349 Certified Power" to add to its list of credentials.

The 2006 Viper's engine was certified through SAE International's Engine Power Test Code - Engine Power and Torque Certification (J1349). The Viper's engine has been certified at 510 hp at 5,600 rpm.

In addition to DaimlerChryler's Dodge Viper, engines from General Motors vehicles also have been certified.

Engine certification is based on a series of self-certification tests conducted by the manufacturer that are witnessed and verified by an SAE-qualified observer. The procedure for certification is outlined in SAE's standard J2723; the actual horsepower testing procedure is described in J1349. Engine manufacturers are free to cite power and torque figures derived from testing conducted outside the scope of the SAE standards, but in those cases they may not claim those figures are "SAE J1349 Certified Power."

Nine other engines have been certified under SAE J1349, including the 2006 Chevrolet Corvette Z06, 2006 Cadillac XLR-V, and the 2006 Pontiac G6. The full list of certified engines can be accessed by visiting www.sae.org/certifiedpower.
