I need advice on Pulley's and the stock 97-00 CL alternator
My friends stock alternator on his 98 Accord just went because of his AEM pulley set so he got a new alternator form acura meant for 97-00 CL.... it's rated at 180 instead of 150 that the accords have. will this be stronger? meaning, will they hold up witht he pulleys unlike the stock Accord alternator?
thanks
thanks

Hmm...that 150 and definitely that 180 sounds high. I am almost completely sure that no CL has anything that high. 2002 TLS's have 120A alternators...I had mine rebuilt to 205. There's no way they put that large of alternators on those cars. As for stronger...anytime you make the alternator spin faster it wears out. Let me make sure I know what I'm talking about, about these pulleys before I go one. The pulleys replace the power steering and alternator pulleys (they're smaller and lighter) so that there's not as much parasitic draw on the car yes? Okay...well this is what I wonder about those pulleys. If you lighten the pulleys you decrease rotational mass, which is a plus. Now if you shrink them you also decrease rotational mass, and you speed up the rotational spin on each. Now you will always have some drag for the power steering and the alternator...they have to spin at certain speeds to function...but if you replace the pulley on the axle driving the other two pulleys you should equal out the speed. The only reason the alternator would be wearing out is because it spins much faster. So unless you need that extra power from the alternator created from extra rotational velocity...then if you change out the drive pulley with a smaller one you should be fine...or if you just get the same size but lighter pulleys for everything. I know this didn't exactly answer anything but I was just curious.
So to answer your Q, no, having a higher amperage alternator means nothing necessarily. Getting that higher amperage can be done by just putting more copper windings in the alternator...but the brushes in it will still wear out.

the pullies are a fraction of the weight(rotational mass) and are larger in diameter. and there is less drag from the accessories because of the larger diameter.

I don't understand. With a larger diameter, the belt in the pulley has to travel a larger distance for the same rotation...so would it not have to turn more? And except for the less rotational weight of the pulley...it will still take the same amount of KE to turn the accessories, you're not changing them. So how exactly do the pullies help the system aside from lessening the loss to rotational KE?

^^^ perfect. i have never had problems, but i also got a brand new battery a few months before the pullies went in. I noticed a little difference in the force required to steer, but the force is still realy light compared to most other cars.

Wow that's a seriously stupid thing to do to your car. Granted if you're running a stock electronics setup I am sure you can get a wheel just large enough to power the system at idle...but I mean geez...I dunno about how smart that is to do. Lighter pulleys I understand...smaller pulleys...eh...
