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, stainless steel pulley hub, an interchangeable
pulley drive ring, and a stock-appearing front pulley cover. The
6061-T6511 aluminum 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.
2.65, 2.5, and 2.4 will require
E85.
