Not worth it in my opinion.

The charge that the alternator will decrease, and the install is a pain in the ass. Not to mention that it does jack shit.

i disagree with underdrive pulleys.

i had one on my previous car and my stereo would shut off often if i wasn't driving, even with a capacitor my sub would drain my electrical system severely.

also, felt like the car was goin' to stall often due to the oversized pulley underdriving the alternator and not replenishing the battery's juice.

i'd also like to hear a review from someone that actually does have the AEM pulley not some guy that has read reviews from AEM and just goes by theoretical knowledge.

You can't really call that a gain considering that a couple horsepower is considered a margin of error on a dynometer.

Slidr and e_degala make some great points.

Some other things to consider are mentioned in these quotes from another site:

2000impreza; "most stock crank pulley's are built with harmonic dampers which makes them absorb a lot of the crank vibrations. aftermarket pulley's don't use dampers for the fact that they are suppose to be light weight. in the long run you might cause more wear on your block bearings."

4wheeldrift; "Some cars respond very well to pulleys, others do not. On most modern cars, your crank pulley also acts as a harmonic dampener. On some cars they will run forever without this dampener, others will kill the bearings in less than 10k. Its a big crap shoot really."

AEM is only an alternator pulley which you dont have to touch the harmonic balancer when you install it. i have one installed with no problems and with gains or not it sure helped my acceleration. no harm done here thumbsup

i have one and the notice was not very much. the throttle response is a bit quicker, but outside that it really does not do much. and you headlights do dim at idle

You can't notice a one horsepower gain (if that's even a gain).

If I were to work on your car and tell you that I installed a fitzer valve that is supposed to give you 5 horsepower, and in all actually, I didn't do shit, then you'd still probably tell me that you could feel the difference.

true but being a lighter pulley(its way lighter than stock)there gotta be some effect to the car besides its not like its an expensive mod to do i spent more money on a pair of shoes than the pulley cost me thumbsup

I know, but it's kinda one of those mods that you put on last to squeeze your car dry.

Bypassing the AC compressor pulley with a smaller serpentine belt would prove more beneficial.

I wish I could go back and never put on my AEM pulley, but I'm too lazy to take it off so, oh well. grin

I agree completely. thumbsup [/quote]The harmonic balancer reduces crankshaft vibration, therefore, it would have nothing to do with the alternator pulley.

i know the pulley for sure is the one that turns the alternator to generate power
and the other i don wanna say cause im not sure
u can use both at the same time but ive heard it ain good

(for celicas)AEM only makes alternator pulley(#1 on the pic)
unorthdox racing makes a set, an alternaor pulley and a crank pulley(#2 on the pic) as someone stated above installing a crank pulley requires the removal of the harmonic balancer which is crucial to the life of the engine. without the harmonic balancer there is a chance you can damage your engine bigtime
(on the plus side note installing both crank and alternator pulley produces more hp gain than just the alternator pulley by itself---there is always a give and take with aftermarket mods happywink )

does anyone have the unorthdox pullies I would like to see how they like them. I hear they work good on Civics, but other then that I have no idea , and they arn't that cheap either. more then the DC header for the GTS.

if you have problems with electrical shit, get a bigger battery...this usually occurs if you're running a big system or have the GT celica.

Undriving your alternator is just plain stupid. Okay, it might give a horsepower or two, BUT think about it. Your car requires your battery to be charged.

So if your alternator is putting out less power it has to stay on & draw power longer. In short, your more likely to loose 10HP cause your alternator is drawing all the time.

An idea might be a manual switch that controls the alternators solenoid, that way you could shut it off & prevent it from drawing power when you need horsepower. That would probably give you 5 to 10 with little effort.
