UR or AEM Pullies??? - Honda Prelude Forum

MugenPoweredLude · 08-09-2003, 04:57 PM

I was looking at getting a set of UR pullies, including the crank pulley...yes I know all the hoopla about it but some have had bad experiences and some have had great experiences.....more so great

so im leaning towards the crank pulley also

or should I go with just the AEM pullies??? altho i do want the most power i can get out of pullies

also, where the hell can i get the UR pullies from if i choose to do so???

TIA

IMO, UR pullies will give you the more power than AEM since it has crank pulley. But it's not safe to put crank pulley on prelude. So i would go for AEM power pulley, eventhough it has less power gain, AEM is more safer.

yea but the horror story you heard about the "UR Crank Pulley" was a imitation......so i might take the chance of the real thing being that much better and not doing any harm....like others have had with the real thing

I'm willing to sacrifice the extra HP it might give you to the wheels. I'd go with the known entity. AEM.

I would go with the UR, that is what i am doing. And the ppl that say they have heard problems with the crank pulley, do u know y this certain luder had the problem?? Well let me inform u that the crank pulley he had was not a UR one, but an Ebay one that he thought was an UR, so when he put it on and crankedwalked, he blamed it on the UR crank pulley, when in fact it was another no name brand one. I have yet to hear any of UR crank pulleys causing a a motor to crankwalk or blow a motor.

I think you will be happy with the AEM pulleys. I won;t comment on the UR crank pulley since I have no experience with it but it seems to be a problem wtih what I have heard.

i remember someone saying that the UR pulley requires the removal of the harmonic balancer which will cause the engine to degrade faster

I have the AEM True Power pulleys and love them. Top end feels a little stronger, but that could just be placebo, but I do know for a fact the car has some extra torque off the line.

I say go with the AEM pulleys. I haven't read anything bad about them and they work great on my car. I haven't had any experience with the UR pulleys so I can't comment on them.

IIRC, its the removal of the stock crank pully that has the harmonic balancer (or is it dampener?). By replacing it with the UR one, you lose that and supposedly 'cayse more wear. So you are correct.

However, it did turn out that big spiel about the UR crank pulley was not "legit" in all aspects. I would proceed at your own risk. I would like to know how they work out after a few months though!

BTW, could you combine the AEM underdrive pulley's with the UR crank pully?

MugenPoweredLude · 08-10-2003, 09:11 AM

for christs sake....the "horror story" of the crank pulley was because it was not the REAL UR Crank Pulley....the other few that have had the real UR Crank Pulley have had no problems...thats why i was thinking about going with the UR pullies...free up some ponies

ive read that you cant use ur and aem together....some say youre alternator wont put out and some say you need like 2 different belts

azninside · 08-10-2003, 09:16 AM

^^ I think you'd have to get different belts cuz of the different sizes if you combine the two.

why don't you do this? get the AEM and the UR, dyno the AEM, see if the results compare to spanishricer's dyno, an then dyno the UR an see how they compare....then you can leave the UR in since they'll probably gain a little more than the AEM, an then see how long til you have a problem.

this would help us cuz then we'd have two more dynos of the AEM/UR pulleys an we'd see if there really are any problems w/ the UR crank pulley.

I bought AEM cuz of the UR talk back in the day, before this new information came out....now that the info is different, I may've gone w/ UR :

MugenPoweredLude · 08-10-2003, 09:27 AM

i got a better idea

how about you give me the money for aem's and for the dyno cuz theres no way im spending close to $500 on pullies and dynos

thats the stupidest response from you i ever heard...come on man

bleacht · 08-10-2003, 03:48 PM

i wouldn't get the UR pullies because of the risk of causing more wear to my engine. those few extra ponies aren't worth it IMO. i have the aem pullies and i felt a difference right away. exactly what pushVTEC said, more torque off the line and top end feels stronger.

azninside · 08-10-2003, 04:17 PM

^^
^^^ actually it's not

it'll also answer any questions bout the UR pulleys causing damage

I've already got the AEM, so if I had the UR, then I could dyno them. you could always buy the UR an I'll dyno both of them for you....that way you're still only payin for the UR

i hope u know that the harmoic dampener was a new thing that honda has put in thier engines for a precaustion. The honda crank has been SOOO well made, that it barely vibrates. So if go see say the first ever made B16(the B16A2) it does not have a Harmonic Dampener, and they still run perfectly after 200,000 miles.

oh yea thats gonna work

azninside · 08-10-2003, 06:18 PM

^^ I meant that I'd send it back to you

NXLude · 08-10-2003, 07:26 PM

Go UR.....more power, more better.....like it was said, Hondas dont really need a balancer anyhoo....there have been several guys on here that had good luck with them

cementups · 08-10-2003, 07:47 PM

more power wiht the UR. Had a set SS set in my Accord and there was a noticeable power difference. GO with your first instinct. If there truely was a problem they wouldn't still be selling them.
