2003 Dodge Ram Hemi Engine Modification - 21st Century Hop-UP
|
Underdriven pulleys for engines are nothing new. Auto Specialties Performance (ASP) has developed one for our new Hemi. The pulley is 20-percent smaller than the factory unit, but the weight of the pulley is kept to the same spec. This alleviates any misfire codes with the computer, and, according to ASP, delivers 12 additional horses and an amazing 19 lb-ft. of torque. it requires a measly 30 minutes to install, and increases horsepower and torque. Sounds like a no-brainer to us. Just keep in mind, you will need to replace the factory belt with a shorter one. View Related Article
