Check out the latest overdrive pulleys released by ATI Performance Products by watching the video below.

ATI released 5-, 10-, 15- and 20-percent overdrive pulleys for the GM LT4 (the punchy supercharged engine introduced for the 2015 Z06 Corvette) as well as a 10-percent overdrive damper for Dodge’s Hellcat engines, and introduced them to the world at the 2016 SEMA Show in Las Vegas.

With a little bit of tuning and E85 fuel, the Hellcat damper will provide a 70-horsepower gain over stock, ATI officials say.
