Product Description
Metco Motorsports is now offering a precision-made supercharger pulley upgrade for the 2020 and newer GT500! Like all Metco Motorsports pulleys, this pulley is an interchangeable unit that is based on a precision-machined, electroless nickel-plated steel pulley hub, an interchangeable pulley drive ring, and a stock-appearing front pulley cover. The pulley ring and cover are anodized in black, and all included fasteners are stainless steel or zinc plated.
These pulleys are manufactured with great care, and special attention is paid to the shape, height, and spacing of the pulley grooves to ensure maximum belt engagement. This extra effort makes it unnecessary to add a textured surface to the pulley ring, as these coatings contribute to belt noise, belt dust, and they rapidly accelerate belt wear.
The original pulley installed on the GT500 has an effective diameter of 3.085", and this pulley size generates approximately 12 lbs of boost. We suggest consulting your tuner to determine the pulley size best suited for your application, or you may contact us directly. Please choose your desired pulley ring size from the drop-down list below. All components are available separately, so once you have our pulley on your GT500, a boost change is as simple as changing the outer pulley drive ring. All boost level changes require the appropriate PCM revisions and the proper supercharger belt. Please note that quoted boost gains are approximate, and that your results may vary.
While we generally recommend professional installation, the optional pulley tools make the pulley swap process much easier. The pin holding tool engages the pins at the rear of the snout cartridge to keep the blower shaft stationary in your vice while the original pulley is removed using our hex insert, as shown.
The 2.85 pulley uses the Micro V K080702 belt.
For all supercharger pulley changes, the PCM calibration for the vehicle must be revised to accommodate the increased boost level.
User assumes all risks. Installation of this pulley may affect your warranty.
