underdrive pulley question

I have searched and know that an underdrive pulley can have good gains... but my question is how about if you don't have A/C or P/S? I know the gains are going to be reduced quite a bit from this... is it even worth it anymore? What kind of gains would you get from that? All that I have up front is alternator and water pump.

Thanks

id say its still worth it, at full throttle your ac will turn off anyways so thats not much of a concern

i bypassed the power steering once at the track and didnt see any gains anyways, so im guessing the gains from the underdrive pulley is from slowing down the water pump & alternator

you should still see simliar gains b/c your making the crank pulley smaller which makes it easier for the engine to rev

my experience with the ud pulley, seems to point to the water pumps as being the hardest thing to turn. i have a ewp (installed before ud pulley) and i noticed the improvement (revs faster, alil more powerful, etc..) it was a noticible sotp feel, where as when i installed the ud pulley, it was as if i didnt do anything very noticible, still felt just about the same- but alot of other people have noticed the ud pulleys when they have not went to an ewp. so im guessing you'd still see an improvement. if you have a mechanical pump. if you have a ewp i dont see the pulley being worth the money.
i have had no battery problems with my ud pulley, but i dont have an aftermarket head unit or amp etc just the water pump, improved speakers, and radar devices i always have on.
