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...

Sweet!

 

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....

 

Just went for a drive, A/C fan blows better, temps stay lower... I HIGHLY reccomend this mod...

now you will have enuff power to run your NAAAAWWWS solenoids and under body neon kit!

 

Dont forget my electrical supercharger!

 

and you can plug your **** annilahtor 2000 ***** in your cigarette lighter and drive with it up your *** now

 

LOL!! I forgot about that! It always ran poorly at idle...Its probably gonna rip now!

 

What does one of those run and where can i get one? does it give such improvemtns as Nos stickers or neon kits.

 

 

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

 

is it strait swap

 

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?

 

You may want to swap out your old wires with new and bigger ones to maximize your Charging System now:
