whats up.. I Currently have UD Pulleys on my ride.. My Alternator took a crap on me and I ordered a new powermaster 140amp street alternator. The tag on it says at idle it puts out 100amps.. and highway puts out 142....

I am curious as to if I should put the alternator UD Pulley on it or not?.. THe alternator pulley I have is much smaller than the stock one on the powermaster.. will that take amperage away..or give me more @ idle?

Thanks

With my 130A 3G I had to stick with the stock pully. My FMS underdrive pully wasnt doing the job

If the pully is smaller, it should turn it faster, thus creating more amps?

I have always wondered about UD pullys, are the rest of hte pullys oversized and the alt. undersized?

Well... looking at your other post, I'd say to leave the alt pulley alone and just swap out your crank pulley to put the stock one back on.
