ATI's New 75mm
Super Pulley with Superior Sprag Technology
ATI Super Pulley
ATI Performance Products, Inc. is proud to introduce
the new Super Pulley with Superior Sprag Technology.
This new pulley will fit F1/F2/F3 and Reverse rotation
Pro Chargers, or any other style of Supercharger with
.8750" and .9911" input shaft sizes. Current
production is for 8mm HTD style belts up to 70mm wide.
The Super Pulley is available in 45 teeth x 75mm wide
configuration at this time. Part #916195-45 for small
shaft size and Part #916196-45 for large shaft. Reverse
rotation is designated with an R at the end of the part
The ATI Super Pulley uses Sprag Technology to release
each time the blower is spinning faster than engine
RPM – thus virtually eliminating belt failures
when the car is pedaled at the drag strip. Also look
for more boost between shifts, as the blower will not
ramp down as fast as the engine during the gear change.
Finally, the pulley will also reduce wear on your Supercharger
by not allowing the gear drive to mesh in the opposite
direction when spinning down. This pulley has been thoroughly
tested and it is ready for your ride.
