Thinkin' bout going back to stock pulleys...

Rerun · Jul 24, 2004

With all the electrical **** I've got going on, huge amp, speakers, etc. I've also got a little bit of a cooling problem going on. Car's fine, except when I get caught on that 405 California traffic, car heats up pretty good. I'm thinking the pulleys are slowing down the water pump which isn't helping.

I've got this tiny ****in' anodized blue ones on there now, I don't even know who makes them. MAC or ASP maybe?

So what do you guys think? Anyone got some stock 92 pulleys laying around they want to sell? Let me know.

good idea, I dont believe in using pullies.

If the ones on 85's are the same i would trade you, and throw in any other stock parts you may need, if you need any. I have a lot of parts. I would be interested in your pullies for sure.

Anyone confirm that the pulleys from the 85 mustang are the same that fit on a 92 LX?

Thanks for the offer 85GTlover, if they are the same, I'll be in contact.

the pulleys are the same because I hooked my buddy up who has my old 82 GT(rare) with my old underdrives...and they work but he needed a new belt...so the bolt pattern is the same....

just reuse your regular alternator pulley, so you don't lose power to your accessories

Well I'm also worried about it slowing down my water pump, I think it may be the source of my tiny cooling problem sitting in freeway traffic.

Underdrive pulley's are lame.
People spend 100 bucks for them, to get less charging out of their alt, less cooling from their WP, and 6 or 8 extra hp?
You can't even "feel" a 6 or 8 hp gain.

Sell your underdrives on ebay for 80 bucks, then go to the wrecking yard and buy all your stock size pulleys for 15 bucks and spend the 65 left over on something good.

Yeah they were on there when I got the car, I knew they were going to cause problems after reading all the fox body troubles with em. I'll probably do like you said and goto a wrecking yard, I've got like 3 or 4 near my house.

Why dont u get yourself some capacitors for your stero system to keep from drawing amps from yours cars electircal system...What exactly does the car heat up to in traffic?

I disagree, i love my underdrives.

I bought the March pullies, but also got the ASP 1 7/8 overdrive alt pulley.

I have a 130AMP alt, electric fan and a big stereo and an AOD and have no charging issues at all.

As for cooling, i didn't notice any jump in temp. I have a stock water pump, Autozone 3-core radiator, 180 thermostat and my Autometer temp gauge never rises over 188 degrees while sitting in traffic on 95-100 degree days. Pullies shouldn't cause cooling system problems, but they will amplify an existing problem. If it too much, swap the smallest water pump pulley you have on there to speed it up

And I DID notice a 6-8HP gain.

Some people are more sensitive I guess

Well, the hottest I've seen it get was yesterday. 405 was deadlocked, was on there for a good 30 minutes. I hit about 220 then I pulled off the freeway, got going again and I got back to my normal running temp of 200. It could be billions of things, I'm not going to worry about it too much right now, I just had the thought the other night.

I do have a capacitor, and a 3G 130 AMP alternator, with upgraded wiring. AMP guage still fluctuates even when I'm doing something as small as using my blinker.

TT91 · Jul 24, 2004

You may need to double check your power system to ensure everything is up to par. I used to be into sound competitions, had 3 caps installed, 3 amps, 6 inline fuses, ect ect. You alternator may be your weak link. Stock?

Took the words right out of my mouth -- in fact, I think I've even said them before. This is 100% true. A stock-type cooling system and electrical system, if running good, will support most cars around -- even with some hefty modifications (always some exceptions when you get to the extremes). Fancy radiators and special water pumps are not needed on most cars, despite the number of people who buy them thinking they are necessary to fix problems.

As for power gains and feeling them -- I doubt someone could jump in a car and estimate it to be 6hp, but I have no doubt in my mind that if I do something to my car and I've gained power I can feel it -- even if it is 6hp.

I see it differently - there are so many variables it's simply not possible to predict how a particular car is gonna react to pulleys. When you slow down the pump and fan and alternator speeds - some cars, even those in great/new shape (like mine was) can have problems. How old the vehicle is, the size/condition of the radiator, size/configuration of cooling fans, addtional electrical equipment, location (Canada doesn't tax the system quite like bumper to bumper in Houston in July), a/c or not, p/s or not, auto tranny or not, HP level -- all these things impact the cooling system; and they vary from car to car. I had to put my stock pulleys back on to solve low speed charging, cooling issues and to quiet a power steering pump that would whine during low speed parking lot manuvers. Stock pulleys returned everything to normal. I traded my u/d's to someone for a set of stock pulleys and some $. What you probably don't want to do is hang with the u/d's and then add bigger radiator, fan, alternator, etc. to solve the problems. If so you wouldn't be the first person whose $69 8-HP bolt on (u/d pullies) turned into a $700 3-HP bolt on.

Do you have the ac going when your locked in traffic? Because I know with my car I can hangout in traffic all day and be at like 190-195 but about 5min after I turn the ac on the temp goes to hell 220+

I disagree on the great shape/new cars idea. However, I do agree, as I've said before - the condition of the radiator, additional electrical equipment, etc. all WILL impact how well the systems work. But, a system in the stock type configuration, working as it should, will allow for the percentage of difference resulting from the underdrive pullies and still work effectively. This all comes back to condition of the other components. If you have an overtaxed electrical system or a radiator that is cooling marginal to begin with, the pullies will amplify the problems.

I take exception to your car, as this engine was never designed for that car, nor was any of the cooling/electrical/anything else. Your experiences may, and I know do, differ.

I will tell you my experiences. Every single Ford I have owned (there have been a few) has had underdrive pullies on it, without any exceptions. I have never once had any cooling system or electrical system problems that appeared after installing pullies -- and that is with all stock replacement equipment. This includes everything from my 350+hp 88 orange car driving in PA heat and in the summer stuck in traffic to my 90 F150 with a little 302 weighing over 14,000 pounds gross with it overloaded pulling my also fully loaded car and trailer across the country in everything from high up in the mountains to desert heat. Never a problem I couldn't fix by replacing stock parts with other stock parts.

Take my opinion for what it's worth, but I'd be willing to bet that if we went and examined cars that claim to have problems resulting from pullies, we could find other problems.

:OT: Sirsureshot I seen pics of you car and was wandering if thats a saleen front bumper you got, and if it is where can I pick one up. I think it looks bad ass..

Michael Yount · Jul 24, 2004

89Mustang - and I'd say for everyone we found with "other" problems, we could find one that didn't have "other" problems. There are simply too many variables for it to be predictable. Trying them is the only way to find out. Glad that yours have worked - but that data simply isn't predictive of what someone else's experience will be. And there are limits to any design -- slow those components down by 25% in an application where the stock design is right on the edge, and you'll have problems.
