Title: 86 Tbird High Output Alternator
Post by: sscobrapride on December 09, 2005, 07:04:05 PM
I saw the sticky about alternators for my 86 v6 but I have a need for something with more juice.  I'm looking at maybe a 130 amp or a 200 amp if one can be had cheaply.  I know that the 90 amp bolts right in, but I was wondering if a universal bracket could be used or the case ground on or something similar to get something like a sn-95 130 amp alt to work.  Any input is appreciated.

They put the 130 amp alternators in a lot of different applications.  Here is the list: 

(1994-95) Ford Mustang 5.0L
(1994-00) Ford Mustang 3.8L
(1994-97) Ford Thunderbird, Mercury Cougar 3.8L
(1990-95) Ford Taurus, Mercury Sable 3.8L
(1993-99) Ford Taurus, Mercury Sable 3.0L
(1995-98) Ford Windstar 3.8L & 3.0L
(1991-94) Lincoln Continental 3.8L
(1992-97) Ford F Series Pickup
(1992-96) Ford E Series Van

Unfortunately none of them have the correct offset mount.  My guess is you would have to fabricate a custom bracket.

Keep in mind the V6s had larger crank pullies than 5.0s. I measured my '87 crankshaft pulley to be 7.46" in diameter. The 5.0 crank is 6" in diameter. This gives a natural overdrive of 24%. A stock 95A 3G alternator will act like a 120A alternator. If you put an overdrive pulley (60mm to 44mm) on the alternator, you'll end up with a total overdrive of 85%. But, you'll likely send the bearings to Hades.

If you want a 180-deg eared 130A 3G alternator to fit in your car, get ready to fabricate.

I have a Taurus 130A on my Bird.... Must come from a 3.0 and will probably have to reclock the rear part of the housing.... Got mine at the U-Pull-It... 14.99....

Sorry bud, I can change that post to something else and pretend like it didn't happen if it'll make you feel any better. ;)
