okay...i'm not to good at explaining things so beer with me. i have an underdrive pulley kit on my car, obviously this makes the alternator turn slower, in return produce less amprage. at idel the radio shuts off and the lights dim. i want to bypass the smog pump (remove it) and use a smaller belt. the ac is already gone. my question for all u smart fellows out there is will bypassing the smog pump help turn my alternator? and if so does anyone now the belt size for a 5.0 with underdrive pulleys, no smog and no ac? thanks!!

gonna have to say NO on this one, your alternator will not spin any fast just because you eliminated another pulley your might rev a lil faster due to less strain on the crank from the smog pump but prolly not going to charge any faster, thats the breaks of UD pulleys

just use the regular Alternator pulley, its only a little bigger and will steal maby 0.2 hp. which is worth not worring about it. When i first got my pullies on my old motor i just swapped the 2 water pump and crank shaft pulley's, noticed a nice gain in some power and never had 1 issue with my alternator.

fix the problem with a 130amp 3g alternator, run a string around the pulleys and measure its length go to auto parts store and buy a few belts around that size, return the ones that dont work, jmo
