H/O Alternator



I was wondering the same, I've got a pretty big system and sick of my voltage drops at high SPL levels.
 
Pretty sure the CP1 Impala's had H.O. Alt's in them...IIRC are's are what...120's? I think they had a 160.
 
The 9c1 impala's came with a 125 amp alternator. Grand prixs came with either a 105 or the 125 amp alt's.
 


Stock W bodies got a 105amp from everything I've found.
Stock Bonneville SSEi's got 125amp
Stock PA Ultras got 125amp (or maybe higher)

Y'all may want to look around for Iraggi HO Alternators and Ohio Generators. Both make alternators for the 3.8L and both are expensive. I believe the Iraggi HO is rated for 14.7v @ idle. The Ohio HO, the one I own, is a bit less at idle.
 
so wish I could sell my alternator from my 1991 Olds 88, it had the series 1 3800, the alt was 200 Amps, thing is still in perfectly good condition, just can't find a buyer

is iraggi still in business? He used to sell his stuff on ebay but I didn't see it last i looked into it.
 
Yeah I'm pretty sure Iraggi is still in business, but the only one that I've heard of that had them for the 3800 was Mechman for sure.

Do those fit on the II's?

it won't fit on the III's so I guess it does not work on the II's either
I just wish all it would take is a different mounting bracket on the alt then it would work, as it is the thing is much bigger and heavier then the stock alt thats for sure
