can i just run the rear half of the main pulley if i've eliminated the a/c and powersteering?

wouldn't this be a 50% weight reduction??

 

Why not run the Unorthodox Racing "R", pulley? It replaces the main pulley and only drives the alternator and waterpump.

 

Must ...... save ..... weight!

 

money, and the fact that their websites says TBA on the pricing

 

I was thinking about that same thing. i don't get why these pulleys are so expensive though. I mean think about it. I can buy the standard issure pulley for like less than 20 dollars, so how come a pretty blue pulley costs 120 dollars for a set? LOL.....

 

I don't understand that either.. Damn.. Someone is making some serious cash.. These pulleys can't be that expensive to make..

I would understand if they are spinning in 100K.. I used centrifuge at work that spins at 140K per minute.. and thr rotor needs to be perfectly made.. But not some small 3-4 inch pulley??

 

Sell the $hit you don't need anymore and use that to buy the pulley. It's just $100.00 ****.
These are the only ones that I know of that offer the main pulley that drives only the waterpump and alternator.
Sure if you wan't invest the time and money and get the thing machined on a CNC machine yourself go for it.

 

Garfinkle s son makes custom pullies .Check with Roterbrain . He has made the double crank pully the idler with the bearing in from the rear , for looks, the power stearing pully, the water pump pully with out the center hole, for looks, a cover for the AC pully .

 

You can take off the front section of the stock pulley for your application. I did it on my fd. I actually had the pettit main pulley and took off my ps and ac and switched to the stock pulley without the front section. i like my car to be fully charged all the time.

 

So if your not using your a/c and P/s the front half of the Main pulley comes off?

 

It does come apart but i'm not sure how safe it is. I have the UR main pully that is just a smaller stock one. Does anyone know if that comes apart too? I cant remember.

Anybody know for sure if i need the half of the Main pulley i'm not using....any of you guys with out p/s and a/c know?

 

i'm running only the lighter rear half, works great

 

Thanks i guess if it just splits in half i can't go wrong. Less weight and recipricating mass....Anyone with no a/c or p/s also done this?

 

As am I, I love it.

 

just remove the visable bolts? how many are there..just don't wanna mess it up. did the pulley move with trying to loosen them with a wrench?

 

4 10MM's

 

anyone have pics of just the back half of the main pulley on the motor? Is there any hp gains since removing the half, its pretty heavy? 2 pieces come off when removing the front half do i leave the small bracket piece on or leave it off?
