I just bought a greddy pulley kit and I was wondering how do you remove the maindrive pulley and the alternator pulley. How much of an increase in hp should I get with it. Thanks.

 

It will help A LOT if you have an impact wrench. The center bolt of the alternator is a pain to remove. You'll need to loosen bolts on the water pump pulley and the air pump.

Looking at the alternator you will see an adjustment bolt on the top right.

Looking at the air pump you will see a bolt on top, one below and one bottom left.

Just remove the bolts you see connecting drive belt pulley.

I didn't have an impact wrench and couldnt get the damn alternator pulley off so I took it to the shop to remove them, replace them, and get rid of my air pump.

about $50
