before i did under drive pullies on my SHO I was replacing them after every auto cross. it is only a 120amp but gets crazy hot. I can attest to the head a alt makes at high rpm.
I didn’t realize heat is such a concern for alternators. I have never noticed my alternator getting anywhere past ambient engine bay temps… Maybe if you were always bouncing off rev limiter they get hot?
Only if you come in wearing your awesome hair, your Betty Boop watch, and carrying Freddy. If, after a short while, I have this unexplained desire to rip your clothes off, then the alternator is all yours.
