Alternator ?

I Installed my HO today in the 110 degree heat only to find out I couldnt use the pulley that came with it. It has 7 ribs and my set up has 6, so I had to put my stock pulley on it until I hear something back from EA Monday.

The one that came on it could **** near fit inside my stocky, there for its not funtioning no where near optimal. I would think it would not make that huge a difference but I guess running a 2500 watt .5ohm amp does affect it a lot. It does OK at speed but idle will drop to the 11s quick and take some reving to get it back up to the low 12s.

Will the right pulley fix my drops? Or does the Alt ****?

Im running 2 type rs at this moment so I dont need all the amp yet. It does OK at around 1600watts

Ive been looking around and I think I can use the 7 grove pulley on my 6 grove belt

Go with a smaller pulley it will up the amps at idle. By making it spin faster

it came with a smaller one but it has 7 grooves and my belt has 6

It'll more than likely slip if your pulley has more grooves than your belt. Also the alt isn't gonna put out full power at idle //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

I know it not going to be full power but its not putting out the 140 at idle it said it would

use the pulley it came with, despite the minor differences it should work fine as long as the belt tensioner is in working order. It should not slip, if it does contact the company for the correct one with the # grooves you need.

Around half way down the page they say that putting too small of a pulley on the alt can cause too much heat, thus decreasing the alt's lifespan.
