Alternator question ?

[bobcowan]

I use a stock 60A unti from Autozone. It's inexpensive, doesn't weigh much, and has a lifetime warrenty. I don't have any problems at idle.

Exactly what I have on both the race car and street car....Street car altr. is about 12 years old now, on sale for 19.99 at the time, race car altr. is 3 or 4 years old now, not on sale, had to pay all of 29.99 for it......Have not had any problems with either....

On my street car I have an electric radiator fan and do at least two 45 to 60 minute parades every year, including the Forth of July (100 degree heat), the only thing I do before hand is make sure the battery is fully charged, so far, in 10 years NO problems..........

I had a 60 amp alternator originally and at idle w/ fan and electric fuel pump running my output would drop to <11 volts. I went with a new 120 amp single wire (same physical size) alternator (with upgraded supportive wiring) and my voltage runs 14 volts at idle with everything running. A large % of my old cooling problems stemmed from a low fan voltage at idle (when I needed it the most) which resulted in a much slower fan speed and a big drop in CFMs. Just my experiance though..

undy are you running a serp belt or a v belt?, the reason i am asking i bought a 95 amp 3g alternator and will be running a single groove pulley and a v belt om my 445 fe stroker but i have heard that that with anything over 100 amps there is a chance the belt will slip?. any thoughts something about not enought friction?.

V-belt ... no belt slip to my knowledge.. The belt's not wearing prematurely anyway.
