Instead of getting a new alternator, I'd like to simply put a bigger pulley on it, to counter-act my crank UDP. Is there one available? I thought I had heard of it, but then I did some searching, and I didn't come up with anything. Any input in this area? Thanks!

Try calling these guys, I bought a high output conversion unit from them and it seems to be a nice product, I haven't installed it yet but the quality is great. http://www.alternatorparts.com/

AdamK. is the one you are after. I think he is on the other dot org.

He has been inactive for a LONG time now on .org, and I talked to him a while back, he is no longer making the Alternator ODPs....

Hm. Shoot. A higher output alternator is always an option, but I really just want a bigger pulley. I'll be looking still. Any other suggestions welcome....

lol you counter your UDP with an ODP? lol why not going stock then?

The ODP just goes on the alternator, giving more overall crank amps. I noticed a lot of loss in my voltage, especialy at idle when switching from regular stock dampener to the UDP. The ODP will loose 1-3HP, but you still gain some HP through having the PS and AC loss.

Keep an eye out on the other dot org. Youll find one used for sale soon enough im sure

any reason he no longer makes them?

A UDP on the crank and an ODP on the alternator is a great setup. The pulley on the crank is much lighter, and it's mass is closer to the centerline of the crank's rotating mass. That's where most of the performance gain lies....not in the fact that it turns the accesories slower. So, you get the performance of the UDP, and you don't lose the speed of the alternator when you use an ODP on it.

The alternator ODP is NOT a bigger pulley. It is in fact nearly half the size of the original pulley and much lighter weight. It must be smaller to turn the alternator faster. A larger pulley, like the Mopar Perf. pulley would turn the alternator more slowly.

I have an Adam K. pulley on my car with an MPx UDP. No more battery lights, 14.7 idle charge voltage and the noticable gains from the UDP were not compromised at all.

lol, you're totally right. I don't know why I said "bigger". Sounds like the Adam K. pulley is exactly what I want. I wish he still made them.....

A friend of mine and I are working on getting some pullies. Not sure if they are going to end up being machined like Adams or if they will be a generic steel pulley that we just did legwork to determine if it works on a neon, but I will keep everyone posted on our findings. Atleast Ill try to remember to come back more than once or twice a month. lol

Thanks! I was kind of planning on doing the same thing....simply looking around for a pulley that would work on the alternator, even if it's just a standard steel pulley. Let me know what you come up with!

hmm...so bringing this up from the dead


would i still have use of my PS and AC if I had one of these ODP's installed?

Yes.


You simply have to get a shorter belt for the alternator.

PN# - 5040295 for a Gates or Dayco. According to Mike Guyer at least...I've not actually installed my pulley yet, so I can't verify it.

whats the point of an overdrive pully? i know theres an underdrive... so... whats the diff?

lilolneon wrote:whats the point of an overdrive pully? i know theres an underdrive... so... whats the diff?

It keeps the alternator from being underdriven by the crank UDP. Basically speeds the alternator back up to where it needs to be at in order for headlights not to dim at idle, especially if you're pushing some power through a bigger aftermarket sound system.


Yes, a crank UDP and a alternator ODP are both SMALLER than original. It depends on what the pulley is spinning though. A smaller crank pulley spins everything else slower, because it's on the crank, not on the accesory. A smaller alternator pulley or a smaller PS or AC or Ultimate Transducer or Jellyfish Banana pulley spins their respective items faster, because it's directly on that item.

Is it okay to run a ODP w/ a stock UDP??

so... if i get a aftermarket UDP and an ODP, ill gain some power, and keep my elctrical crap at normal operations?

I know this is minorly off topic but has anyone had any problems after using an UDP for A LOT of miles, (50,000+ miles)?

And if Im not really stressing my alternator, no system or other big draws, is an alternator ODP necessary?

Yeah.

I've only had my UDP for 30K, and everything is perfectly fine. And by no means is the alternator ODP necessary...you're not hurting your alt with a crank UDP, but at idle you don't produce the voltage that you normally would. It's not bad, but I just hate my headlights dimming. Plus, idle is the only time the ODP really makes much of a difference.

probably, but you run the risk of frying your battery and shortening the life of the alternator

hmm...expensive battery + expensive high amperage alternator + ODP = bad??

If you have a high amp alternator and a stock crank pulley (the stock pulley is NOT an UDP *under drive pulley*.... its just a stock pulley) then you really have no need for a ODP at all.

An ODP on the alternator just counter acts the effect of a *real* UDP, and is a weight redux item.

I knew it wasnt a real UDP...the stock pulley, just didnt feel like typing it all out...so I was being lazy for once, sue me

but thanks for all the info

you know he started another group buy on these right? i think he is still waiting for them to get in from the producer he goes through, but he had a group buy not to long ago...i asked on April 23 (i think) if it was too late to jump in and he replied that it would be goin on for a while...it's in the vendor/group buy section on the .org, hopefully this will help someone who may be in search for one of these still...
