Has anyone run into problems with electrical stuff because of underdrive pulleys. I would think it is not good for a car with tons of power options to have the alternator slowed down. Power pulleys seem like a cheap way to pick up a few horses but is it justified with the alternator turning slower?

for $100 they area good mod for the power. i have had zero problems over the last 2 years. ur headlights will be slighty dimer at idel but nobody ever noticed. only mee cuz i sat there and loked at them against a wall. but if u get hids that problem is a thing of the past. highly reccomend the aem pullies. if u have a 3.0 the istall is more complicated and if u dont have a denso alternator then u might have probelms. lots of poeple with the cord v6 have had problems.

I actually ran into my first problem after 3 years with the pulley for the alternator.

It was raining and my inside windows were all fogged up. So, I had the rear window defrost, regular defrost w/ac on full blast, my stereo going, my headlights on, and my fog lights on. As you can see, I had a lot of stuff going at once. To top it off, I was only driving about 25mph through residential street. I noticed that my lights were dim, then my stereo turned off. Next, my ABS light came on. So, I put the car in neutral and started to rev the engine up. My lights became bright again and after a minute, my ABS light went off.

I guess it was too much for the electrical to handle at one time.

ur battery could be on the way out! at 25 ur alt should be makin enough power. sice u say u have had no probs for 3 years its seems odd. what kind of stereo? cuz if u have a system with subs then i can understand your problem. even at idle in the summer with my ac blasting, lights, fogs, and stereo on i have never had a problem. i do have an optima battery though. i always buy new batt every 3 years at least. i dont care how long they claim to last. not worth getting stuck.

I am going to get a new battery. I was going to PM you about your optima.

Also, I am running an Alpine amp with max output of 700 watts running components all the way around with a 10W6v2 JL woofer. As you know, one of those woofers can run with 400 watts rms. It a decent size system.

But for sure, I am going to look for a new battery. That is, after I go fill up my nitrous tank today!!! LOL!!!

When I had 3 12"s and a 800 watt (800x1 RMS) amp including a 4 channel amp (4x40 RMS) yeah, my headlights dimmed like crazy...but then I took out the subs, the 4 channel amp, and put 1 sub in there. Oh, and then I bought a conversion kit...so no, nothing dims anymore :P I didn't feel any gains with the pullies, but then again, the gains are gonna be up in the high RPMs and not the lower end.

So i guess the main thing is to have a good battery if u are gonna run power pulleys. What do pulleys give you on a 3.0? I have read between 5-12 hp but that was advertising so i take it with a grain of salt. Also i wonder if you can install the other pulleys and leave the alternator pulley stock, this would eleminate electrical problems but maybe 1 hp less. Anyone ever try that?

VXCL

the dyno on an 97 accord ex with bolts on i saw they had about 1-2 hp increase throughout rpm range and 6 hp peak. so that is what to expect if u have a 2.2 or 2.3.

Cilver2.3= if ur system hits alot nicer after u get a new battery, than ur current one was definitley on the way out. my optima is now garbage, from storing it for a while. cant get a new one either cuz the place where i got it from no longer exists and optima wont help me. they reccomend i buy my next one from pep boys so if i have probs they will exchange it, but they only have 3 kinds and they suck. im not going from a 850 cca optima to a 600cca optima. my car used to start so nice! i think i might get a yellow top instead of red this time cuz at college my car sits for a week or more sometimes. but i dont like the color yellow and they yellow has a lot less cca's, but it is a deep cycle

i have had a problem keeping belts on my alternator.
they were wearing on the passenger side of the car every time
after 3 belts in a 4 months i put back the stock pully

no problems so far

they worked fine for the first year ?

VXCL

kiljadeon something definitely wasnt right. either ur aem pulley is defective or u got the wrong belt. u shoudl have no probs. tell aem ur prob. maybe they will help you

Kiljaedoen

ok i will do that

i got the belt # from aem

and the belts from car quest

Power Pulleys can be really harmful especially to a "luxury car" with all the buttons.

Here you can start here for a better understanding. Cheap power not dealing with immediate airflow is most likely not a good mod.

VXCL

not all cars are the same and the alt that comes in most f engine accords (cl) has enough reserve. it is extremely rare some1 has a problem with aem pullies if they have a 94-97 cord or 97-99 2.2 or 2.3cl.

Kiljaedoen

with my pulleys I could blast my system and my A/C and have my lights on at idle with NO problem at all. But I do have my system done corectely. New battery (optima yellow top) and a 1 farad cap. So alot of the drain was taken off my alt.

VXCL do people somethimes have problems with eam pulleys on the 3.0 CL??

Kiljaedoen

The 3.0 motor is the same as in the v6 accord
the 2.2/2.3 is the same as in the 4cly accord

Does this answer your question

giugiaro_RENAMED

so unless you have a denso alternator the power pulleys are a bad idea on the 3.0 CL
