My 1998 AHU 120 amp alternator has a W terminal. I am pretty sure my brothers 1996 AAZ 90 amp has it too.

I bought a 120A AAZ alternator for my build. It has a W terminal, don't recall the p/n off hand. So yup they are definitely available!

The other question around the clutched pulley - all it does is make the alt spin at a more constant rate. So it definitely does not affect the rev counter.

Will my lights get brighter with a higher output alt?

[vanbcguy]

Probably not. Most higher output alternators are actually worse off at lower speeds.

Adding relays for your headlights most definitely WILL help though. Huge difference on my car. Stops your headlight switch from burning out too.

I got a pre-made harness with relays and everything from 4crawler.com

I wish I could get one of those but they haven't had them instock for 2 years and whenever I ask the dude sends me the same copy and pasted message.

The only advantage to a higher output alternator is that you can run more things at once lol. To make any circuit "better" you would nee to upgrade their components and wiring. Assuming the lights are being dimmed because of voltage drop, larger more direct wiring (relays) will always help an electrical circuit out with efficiency.

Installed headlight relays\wiring on my mk1 jetta, and I was happily surprised by my new found headlight brightness.

They also help with jumpstarting other cars.

Very true.

I have a  f350 battery and 120a alt. Jumpstart king!

if you had a split IC line, and were still making 15psi at the intake, then you were DEFINITELY making ALOT more boost than that at the turbo..

you likely killed the oil seals, and maybe bearings in the turbo...

yep turbo shaft was blue from heat... could look in the oil return side of turbo oil line to see... but hell borrowed turbo to see if resolved.. it did.. but i popped it one night screwing with subaru.. wastegate was little iffy and guy was a dousche.. so i smoked him real good... but broke borrowed turbo as now it no spool right.. wish i had gopro.. turbo upgrade time...

with hid you can run 55amp alt no issue... 100w/80 h4.. need 60 amp min alt.. my hid pull so few amps...
