The pulley system includes HUB, pulley of your choice, 5 stainless socket cap button screws, and one barbed retainer to replace the breather bolt.

After removing the stock pulley our steel hub presses on using the same pulley tool used to remove the factory pulley. No jaw style puller should be used to remove a supercharger pulley, if it is used, it will destroy the pulley and possibly damage the supercharger.

Once installed the hub allows quick changing of pulleys with an Allen wrench. The ZZP MPS allows you to change between pulleys depending on conditions, use one pulley for street use and a smaller for the track or when running high octane fuel. A modular pulley system is a must for those planning to continue to modify their car in the future.

Our pulleys come with 8 ribs on them, but a 6 rib belt will still work completely fine.

Fits:

  • Pontiac Grand Prix GTP or 06+ GT
  • Buick Regal GS
  • Pontiac Bonneville SSEi
  • 04+ Impala SS
  • 04+ Monte Carlo SS

Pulley recommendations:

  • 3.5 pulley for 01-03 GTP/GS with ZZP PCM, Tstat, colder plugs, bolt in downpipe, and a cold air intake.
  • 3.5" for 2004+ Grand Prix recommended for cars with 1.9 rockers, Tstat, colder plugs, some exhaust work, and a cold air intake.
  • 3.4" for 97-00 GTP/GS with ZZP PCM, Tstat, colder plugs, bolt in downpipe, and a cold air intake.
  • 3.3" pulley requires a small cam or headers or any SS intercooler
  • 3.2" pulley requires a XP cam or a SS intercooler with 1.9 rockers.
  • 3.0" pulley requires larger injectors and a full size intercooler
  • 2.8" pulley requires a cam, intercooler, and headers.
  • anything smaller than 2.8" pulley and you should email us your specific mod list and octane.

Woke my Monte right up! x2

This was a great add-on for the 1.0 PCM. These small mods make it feel like an entirely different car. Would recommend to anyone looking to get that 3800 boosting slightly more.

MODULAR PULLEY SYSTEM 07GT/GTP 3.5 PULLEY

This is a update to my review from 10/07/16.The 3.5 pulley nds. 96/100 octane fuel to run on a Series3 3800 otherwise the KR really kills power.Reinstalled the 3.6 pulley & ran 13.85, 106 on a G-TECH PRO RR on Oct./2017 w/3.6 pulley,3"DP w/hi-flow cat,104 Autolite plugs w/12/13 psi. of boost.The MPS makes pulley swaps easy & the polished silver finish adds sparkle underhood. The 3.6 MPS is a must-have mod & the 3.5 nds. supporting mods w/o KR. Easy install..biggest issue is removing the factory set-up.

3800SC in Fiero

I bought this hub/pulley system to make quick changes to the pulley size on my 3800sc engine. I rented the hub puller and could not be happier with this purchase. Instructions were great and new pulley looks awesome on.
