Better alternator option
#31
The Bosch AL7558X is a rebuilt Motorcraft 6G series small case alternator. The standard rating on these was 95amps. While they can be modified to produce 200 amps, doing so on a small case alternator is probably not a good idea if reliability on longevity are priorities of yours. Additionally, they're like many high amp alternator upgrades where their performance at idle isn't much different than a stock 95 amp 6G.

Thanks I should be getting a 84 928 here in a couple of weeks.
Great solution. Lighter too?
This should matchup to 32V.
(True Bosch factory rebuilts are not unreasonably expensive either, though, and can be bought from Advance Auto.
Haven't had any charging issues or dim lighting with Bosch on our 85 or 86 with rest of electrical system completely serviced.)
84 and earlier have different mounting arrangement against the block.
Delco 88 camaro alternator will work on those.

I used a 34" belt. I don't have a part# since many brands use different numbering systems. With that said, you can usually determine the length and number of ribs on most belts by looking at the number. Somewhere in the part # you'll see a 34 and then a 6. You may want to try the stock belt first as it might fit. The belt I used was only about an inch longer than the stock belt.

Question: The Ford 3G, Ford 4G and Bosch AL7558X alternators appear to not be able to accept the housing for the cooling hose. Since an external temp sensor related to HVAC function is buried in the front end of the hose, what is everyone doing to address that?

Just an update. Put about 175 miles on it today. So I've got a total of about 400 miles on the motorcraft alternator. No issues whatsoever. Haven't put the pressure washer on it yet. But when the cold front started moving through tonight, I did take it for a drive while it was raining heavily. Wipers, headlights, radio, rear defogger, and front defogger running, and it still indicated 13 volts at the dash.
Driving through puddles and swamping the Bosch with water would usually cause the voltage to drop off significantly. Swamping the motorcraft seemed to help clean it up.
I have no intention of ever putting the Bosch back on the car.

Has nothing to do if the bosch alternator is there or not. Nobody said remove it.

Looks like I'll have to change my alternator on my '86 32V this weekend or next. $170 new sounds good. This set up looks extremely interesting to me slash fun to try. Although I have a question regarding the non-LRC regulator. When I order the alternator do I ask for a specific non-LRC contour alternator option? Or is it the regulator off a different model alternator entirely? A model #? Cost? Ease of acquisition?

My only concern with this style of alternator is probably my specific situation.
I 'had' a 200w alt fitted, like the one mentioned above as I run some pretty big audio amps.
I was told that i would no longer need cooling ducts as these fans pull air from the front to keep cool.
The problem is in my case is that at idle, hot day, sitting in traffic, stereo pumping, tha alt puts out a lot of current AND heat.
In the end it just fries itself and here in OZ i was unable to get it rebuilt.
The vendor is not cheap, mounts are good, but for high outputs its a poor solution.
For normal use it could be an easy cheap fix, but just be aware of the heat output at idle and the cooling required to keep the alternator from burning up.
It cost me Alt +tow truck + another new alt + masssive hassle.
