Underdrive pulleys

KevinJ99GT · October 19th, 2008, 01:38 AM

i have two 12" subs but it doesnt seem like it pulls alot of power so udp should be okay right,and i think everyone suggest the Steedas?

SWEET2KSTANG · October 19th, 2008, 03:18 AM

will be just fine, if amp is drawing a lot of current i suggest getting a capacitor as well.

i dnt kno about ur eletrical power issues, but i have steedas and like them. Theres no point in spending 50 dollars less for pos ones, cause there cheap enough as it is.

If you're really concerned, save up and spend the 150 or whatever on an alternator from PA Performance, they make ones that go all the way up to 200 amps (those are about 300 I believe) and at idle they're making 130 which is what the factory alternator makes at about 5k rpm. They make less powerful versions for cheaper. I plan on getting one soon because my system, even with the capacitor, is killing the alternator on there now.

how do pulleys do on a supercharged car?

02GTVERT · October 19th, 2008, 04:21 PM

i have heard that S/C applacations you must run stock pullys. You can get a S/C pully to bump up the boost tho.
For the other guy go with steeda like everyone is saying. Im real happy with mine and no power loss to be noticed! Is it important to look at a water pump with UDP?? I have stock and it all seems well right now.
