Underdrive Pulleys

[gadget73]

What is it with people hating on the AC?

[Blaze86Vic]

Since you guys are talking about pulleys and belts ..We wanted to take the A/C out of vicky and I had a few ideas but the car isnt here right now for me to look at and describe what the ideas are But it involves power tools...Ideas anyone?

If I remember correctly the only things on that belt are the AC and the smog pump. Just remove both of them.

Ill agree with mike too, I threw my belt off the alt/power steering pump before when I had it opened up good.

and bent alternator fins because of over revving the accessories.

I was going to call BS in that statement Mike, but I bit my lip. There is just no way that could happen, but as I am working on my car now, I was putting my alt back on and noticed black marks at the tips of each alternator fin, and what do ya know. They were all bent up. So I'm gonna have to back you up on that now, slow down the pullies if you have an HO!!!! I went ahead and put a larger alt pully on for now. I guess as soon as I have the funds I'll be purchasing that UD pully.

Its bigger than the steeda one I replaced it with.

Putting a smaller pulley on the alternator is the same as putting an overdrive pulley on the crank. To slow accessories down you want a bigger accessory pulley and/or smaller crank pulley.

the pulley off of my towncar alt is slightly smaller than the pulley on my vics alt.

On a non-HO, probably not much. And yeah, for HO engines it's because fo the much higher RPM that they reach. I blew every single hose off my old car, melted alternators, and bent alternator fins because of over revving the accessories.

Yup, but if you're running an HO or something insane like me, you NEED it.

Why is it needed for regular HO engines, cause of the higher RPMs they go to? If I install an underdrive pulley on my non-HO engine what gains will I see? (already got the HO intake and the free flowing exhaust)

Thats not that bad. And they kinda got ya by the nutz if they are the only manufacturer of a pulley specific for our cars. I'd rather spend that and get new belts then screw around with a comple mustang accessory change-over. If i switch to that pulley, what belts should I be lookin at gettin

[mrltd]

Daaamn, $125? Add the belts to that... not in my budget unfortunately, otherwise I'd all over it.

I have a similar underdrive crank pulley, but it's a Moroso brand. It's for a single belt application. It's never been used, but a little older, still has the instruction sheet I believe. I'll let it go if someone wants to purchase it, since I have functional A/C on my car, I can't use a single belt.

Make me an offer, I won't be insulted. I'll get a picture soon, too.

You cannot use the stock belts.
