Hawks Motorsports offers our clients this 1002-270 8-Rib Magnuson 4-Bolt TVS 1900/2300 Blower Pulley, 2.70-Inch, Innovators West. This upper supercharger pulley is designed for Magnuson TVS 1900 and TVS 2300 supercharger applications using the 4-bolt, 8-rib pulley arrangement.

If you're spinning a TVS and looking to get more out of it, pulley size is where the fun starts. The 2.70-inch pulley puts more RPM into the blower, which means more boost potential and a harder-working supercharger. This is the kind of upgrade you throw on when you're done leaving power on the table and want the blower moving some serious air.

The 1002-270 is part of Innovators West's 1002 series of Magnuson TVS blower pulleys, available in sizes from 2.70 to 3.60 inches. The smaller 2.70-inch diameter is intended for higher blower speed and increased boost compared with the larger pulleys in the series.

This pulley uses an 8-rib configuration and 4-bolt mounting pattern for compatible Magnuson TVS 1900/2300 supercharger systems. It is not designed for Magnuson Heartbeat superchargers.

INSTALLATION NOTES:

• This listing is for one 1002-270 2.70-inch blower pulley.
• Verify the supercharger is a compatible Magnuson TVS 1900 or TVS 2300 4-bolt, 8-rib unit.
• Verify pulley alignment with the existing 8-rib accessory drive.
• Confirm adequate belt wrap and belt length for the pulley combination.
• A smaller blower pulley increases supercharger RPM and can increase boost.
• Verify the complete combination is appropriate for the intended supercharger speed.
• Recalibration may be required after changing supercharger pulley size.
• Verify fuel system, intercooling, belt drive, and engine calibration are appropriate for the increased blower speed.
• Do not install on a Magnuson Heartbeat supercharger; the manufacturer specifically states this pulley does not fit the Heartbeat series.
• Test fit and verify pulley alignment before final installation.
• Follow the supercharger manufacturer's installation and torque procedures.
