I got them. smallest available, 52 mm o.d.A socket hardly fits.$24 shipped.
Yup thats all I needed to know, thanks everyone...yup, i am running one of ron's pulleys. it picked my voltage up from 10 to 12 at idle
So you guys add them to your 105 amp alternators? Does the stock belt still fit good with this smaller pulley? Im holding off on a bigger alt. because with an efan running and my 900 watt stereo system running, it needs some more power at idle.
true it would seem that way, but ive had mine like this for about 1.5 yrs on a 145A, no problems, if the alt craps out i still have my stock 105 to get around on for a while, and i will just order a higher amp alt, its worth it to not see my volts drop to 12.8 while idling and the e-fans come on, now they only drop to about 13.5 and then go right back up to 14I'm sure they work well, but I'd also think they'd...
a) increase belt wear, due to tighter radius, and...
b) shorten alternator life, due to the greater constant and ultimate RPM
Fair enough...I can see it being a less expensive option to replacing a functioning alt. I'd just keep an eye on the belt, checking for accelerated wear.
I do think so.is it a bitch to get the pully off? can it be done while the alt is in place?
yep:shake: i removed the belt, grabbed ahold of the stock pulley and hit the nut on it with an impact wrench. backed it right off. had the old one off and the new one on within two minutes.:jester:is it a bitch to get the pully off? can it be done while the alt is in place?
