Anybody running a 100amp alt on their race car?

I run a 90-110 amp denso from a 88 or 89 dodge truck, on my slant six. The only wiring I changed was adding a 8 gauge direct from the alt to the battery. On a slant six you only need to cut a 1/4 inch off the front of the cast alternator mount, and everything lines uo.
I have two electric fuel pumps, Electric fan and water pump, MSD, nitrous bottle heater, nitrous solenoids, plus I run headlights coming back to the pits. I also installed a normally closed relay in the in the field circuit of the alternator, that is triggered by the full throttle micro sw. The switch turns on the nitrous, and shuts off the alternator, any time the throttle is wide open, but allows normal charging at any other time.

The only time I have a problem, is if I get running my mouth, and forget to turn off the fan and water pump, after the engine has cooled.
