To all who were interested, the AEM part # on my power steering pulley is: 2-6501
My boyfriend has a ton of misc. AEM pulleys laying around, he found one to fit my power steering pump....you need to buy a belt that is one inch longer than the stock belt....he has another pulley that he thinks will fit the alternator, I will put up a new post after he tries that one out and let you all know how it goes!

Nice find there!
I just have a question, shouldnt the belt be smaller cuz you want to put a smaller diameter pulley to decrease rotational mass? Either way, I bet there a lot lighter. What is the weight on both stock and AEM?

that really wont help performance much... you are over driving the pump...

Awesome!
But her saying that you need a belt that is 1 inch longer means that the pulley is larger, thus it's spinning the pump less, hence less hp required to drive the pump.Originally posted by DXHATCHBACK

oh... shit! thats right! sorry... plus the pulley is super light

hey on this site http://www.indigospeed.com/GTPullies.html is says the pulleys u get from there will increase horsepower from 10 to 28 hp, whats thats all about is it true.

I was told that they don't but I think I told the person they were under drive pulleys. Those were the same that I was talking about before but, I just said the wrong name. They might but I highly doubt they would create that much hp at the wheels.
every little bit helps is the way i see it.
But for a $139 plus shipping it might not be worth it Mantis. The money could be spent on something else that could increase hp.
Ya, those 10-30 hp number are bs. You'd see maybe 1-5 hp. The real gains are that the engine revs faster and smoother. Less drag.

I would spend money on a cam or something rather than that. I think those would be good if you had nothing else to improve to your car.
does the our accord have afermarket cam gears does any one know

No aftermarket cam gears or camshafts. We can get our cam shafts re-ground so they will be more performance oriented.
i thought that the underdrive pulleys were smaller because isnt a smaller pulley easier to spin than a larger one? same kinda shit with bigger tires, am i wrong?
I believe they are lighter and smaller. The ones on the site are different from the AEM that is in the first pic.
well maybe isadisa can give us some insight on how much it helped? since shes the only one who has it done! lol
Nope, if the pullies were smaller, you'd need a belt that is shorter. They are larger, hence the need for a 1 inch longer belt. Yes they are lighter, because of what their made of, vs stock.Originally posted by Mike's89AccordLX

i know three people with underdrive pullies and they said it really worked. its one of the few things he really felt a differnce.

i have spare pullys laying around, if i were to shave them so they are lighter would that help? even small bits? hmm here is a good project for me, i could also polish them to a shine.
Completely opposite, actually. The larger the pulley diameter (since it's being turned from the outside diameter of the pulley) the easier it is for the engine to turn it, which is where the power gains come from. Just like the gears on a bicycle....when the chain is on the big gear on the tire you go slow, but it's really easy to pedal. When it's on the small gear, you go faster but it's alot harder. Exact same principal.Originally posted by SiCReX

I was trying to think of a way to explain it, but nothing came close to that analogy. :super:Originally posted by Jareds 89 LX-i

The larger diameter (reduced pump speed) is responsible for most of the pulley's affect, so making it lighter (and more fragile) probably won't help much.Originally posted by Mantis88LX

Ok these underdrive pulleys, how many are there? Just curious to see how hard it would be to install them.
