Spent last night converting the car to an FD alternator. Wasnt too hard, except for widening the spacer...

Good going, notice any power improvements ?

Got time to do a write up?
That sounds like something I may wanna consider at some point.

Are you kidding?!?! That thing is the SHIZNIT!!! My fans run better, the car feels better (could just me be), I am really happy about it!

Well how's the output? How much has it helped?

I used this write up to do it...

I get 14.5 volts at idle, no loads. At idle with E-fans, A/C, rear defroster, headlights, I get about 12.9 Volts. The thing puts out some juice....

Here is a side shot...

What does a FD altinator go for? what brand did you get? Got it new at a parts shop I assume?

Its a Pro Amp alternator, it was a little spendy, about $160.00. It was a toss up between the $199.00 135 amp that Alterstart makes, or the FD alternator. The FD was less expensive, so I went that route. I wish I could have gotten one used, but they arent easy to find here....

Hey, J-Rat... how'd you do the pulley for that thing? I've been looking for a V pulley for this thing for a while.

I got the pulley off of an old '67ish GM alternator. For some reason, it fit right on. Its the one peice style. My guess is, I got lucky. The only thing I had to machine was the spacer. From my experiment, I gathered that all GM pulleys will fit. You just gotta get one that wont grind the case. Plus I tried to custom grind a spacer, that was harder then I thought, so I just widened the orignal FC spacer with a Dremel. It fit like a champ..

I can do a write up if you like..Honestly, it was a really easy conversion.

I neeeeeed to know hows it done

NRA T2

is it strait swap

JumpyRoo

A dremel... I tried drilling out the FC pulley and I couldn't get an even circle. Trying to get a spacer that doesn't grind the case is hard. I really don't know how the FD serpentine pulley did it, but it did. How do you tell?
