After months of testing, Dayco is introducing two new belts to the market -- a supercharger belt and an 8mm blower belt for street and professional racing applications.

“Our team of engineers has been working diligently for the past two years in order to develop these two extreme performance belts. And we are thrilled with the internal as well as real-world test results we’ve seen for both of these new belts,” says Jay Buckley, director of product management for the Dayco North American Aftermarket. “We are committed to bringing to market products that can handle extreme conditions like those experienced on the race track and can’t wait to see how these two belts help some of today’s drivers level up.” 

The Dayco 8mm blower belt features high-strength Teflon-coated teeth for cogged drive pulleys and a carbon cord construction for durability. Similar to its predecessor the 11mm blower belt, it was engineered using real-world on-track data that enables it to withstand the rigors of 4,000 horsepower top alcohol dragsters and pro-modified race cars. It will come in multiple lengths and 50mm, 75mm and 84mm widths and be available to order as of January 2022.     

As for the Dayco supercharger belt, it uses high stiffness PET cord, EPDM proprietary construction with aramid fibers, and either 8 or 10 ribs depending on the application, this poly-V belt also features the Dayco racing logo imprinted on the belt. With 17 part numbers that cover 150,000 vehicles in operation, this belt is engineered and has been tested for use on late model supercharged cars with light modifications such as the ZR1 Corvettes, Shelby Mustangs, and SRT Hellcat applications.
