Would you PAY $34 for a belt???
Good year GATOR BACK BELTS. #15321 There $17 dollars each. Just got the dual rotor shaped pulley from higgi. and changed belts. Removed A/C, Air Pump, PS Resivor. Feels alot lighter upfront. notice a little difference in HP. Oh yeah BTW the belts have a LIFETIME WARRARNTY...just doesnt cover obvious faluty installation. They have a sideways teeth (cut ) to them. Really good and GUARENTED NOT TO slip or squeel.
My experience so far they are GOOD. No slippage or squeeling. High reving too...

If it is the appropreiate part to do the job properly then they are cirtinly worth the money.
Are they matched belts? The doubled up alt pully should have matched belts. That is (in case you don't know, bc I didn't) two belts that are garinteed to be the exact same size.
In any aplication where you have doubled up belts they should be matched
any way they sound like a good belt

AND YES SOON I WILL HAVE 323 POSTS ! ! !
BIG *******
UPantrax-- YEAH THERE MATCHING BELTS BOTH 15321.
THANKSRaptor13x-- THESE BELTS ARE LIKE I SAID GOODYEAR GATOR BACK BELTS W/LIFETIME WARRENTY !
THATS WHY THERE SO $$$. AND AS FAR AS BELTS REGULAR BELTS RANGE ANYWHERE FROM $5-$20

A yoohoo belt wraps around the main drive pulley and the waterpump pulley ONLY. The standard alt belt is still used in its stock location. The yoohoo belt sits in the air pump sheaves.
My theory on why it works as well as it does is this: As RPM rises, a spinning belt tends to want to go round from centripidal or whatever force. With a yoohoo belt, this is beneficial because it gets forced against the sheaves and will not slip. This same effect on a standard 31513 type belt (alt, wp, main) makes the belt come away from the wp pulley as it tries to go round.
Look at the front of your engine and see how little contact the wp normally has. Very little! Now imagine high RPM and the belt(s) stretching away from the wp pulley sheave(s) while pressing harder on the alt and main drive pullies. Slippy slippy!
Way back in like '73 or so, the water pump pullies were further away than they are on '74 and later engines. These '73 engines most likely do not suffer from the dreaded belt slipping problem we're so used to on our 'modern' engines.
I'll tell you what I'm gonna do. I've got a '73 12A and a dual sheave pulley on one of my alts. This alt is on my REPU which has a clutch fan. The belts slip and are at spec tension. Result? I'm getting a yoohoo belt for the truck and a different alt (single sheave) is going on it (no point swapping pullies when I've got three of the same type alts). The dual sheave is going on the '73 12A. I may be able to find a somewhat longer belt that will fit on the '73 pulley, but for now, it'll just use my dual belts if they'll fit.
Can't you tell I'm a convert to the yoohoo belt?
'74 and later engines (except the 20B and 13BRE) can use a 3L220 or pretty much any other 22 inch 3/8th" V belt. I've got a part number here for a Napa Gates belt that is a little wide for the sheaves, but usable. It's a real automotive V belt, not a fractional HP like the standard 3L220. The part number is 7215. On the back it says:
25/64" x 22-1/8"
9.5/10mm x 560mm
The correct length is supposed to be 558mm or 22.0 inches, and the correct width is supposed to be 3/8th of an inch, but this belt is the only one that Napa had, other than the smaller, thinner, weaker, fabric covered 3L220. But I figured the extra length would be compensated by the extra width, which will wear down eventually. Then it will no longer be as effective at lower RPM, but it will still do its job at higher RPM, where the extra grip is needed anyway.
Now that I've made you read through all of that, I guess I could also give you the short version: Forget about dual sheave alt pullies. Save your money and get a yoohoo belt and forget about it.
Note: you gotta pull your fan to install it.
No offense to anyone buying or selling pullies. This is just my personal opinion, and it may not be correct at all (that's sorta the nature of opinions though. You know?).
There's even a picture somewhere that Blake posted of his 11,000RPM PP 13B with a little diagram of the yoohoo belt and such. I'll go looking for it...

Here's the pic, but I don't think it's online anymore.

Maybe Blake could come by and post the pic here? Or maybe it's already on this server?
Yo, Blake!

I`am also running Goodyear gatorback,on a twin belt alt pulley.
They gave me good results.
I tension mine,so that its 0.15 ".Thats the only way that it doesnt slip,when my engine use to rev over 6krpm

I've never had a belt problem. Use standard NAPA or Kragen $10 belts, tensioned per OEM instructions. Rev to 7k couple times a week, temp gauge is steady, no squeal, alt gauge steady, etc. AC works.

thanks for the info Jeff. but i dont have a air pump. these belts are very good and dont slip or squeal at all i rev my evgine to 7k at least everyday, and havent had any slippage or sqealing problems but ive had the belts for like what 1 week so ill keep you posted if there worth the $17 for eace belt. im still sure that wont give me any problems....but who knows we'll see.
i've heard something about that too that you dont have to get a dual pulley just a 22' in or that whatever belt your talking about...will this work if i dont have the air pump???
karism-- yeah there good belt's how much did you pay for yours???
gregs-- its a riced out RX-8...heres the or the pic if i can upload.......
