installing a 100amp alternator

If you add electronics and accessories like radios, electric fans, high output ignition systems you need the extra juice from a higher output alternator. That's why :-).

I'm aware of that yer sillyness. What I'm referring to is this particular unit, which is huge, giant, monsterous, and when used on a high performance high RPM engine just might come apart from together. Read the rest of what I wrote.

.................Not sure why guys want to do this, ....................Remember this: These have, relatively speaking, HUGE rotors. Just about any rotor is geared (pulley ratio) 3:1 or 4:1 above crank speed so if you are spinning the engine to only 5K that alternator sees at least 15 THOUSAND RPM!!!!

I used to run one of these when I had the "wench" on the old FJ-40, but I wouldn't want one my my Dart

There are much much more compact and better designs out there nowdays than these huge anchors
