What does the amp rating have to do with your supercharger? It is belt driven.

It has nothing to do with a supercharger. You have something mixed up with your terminology or with your understanding of how these systems work.

There's no such thing as a 300 amp generator for a car. 130 amps is way more than you need. Also, you don't "fry" anything by installing a generator with a higher capacity. They self-regulate due to their design and will only deliver what the electrical system needs. Just because it has a higher capacity doesn't mean it will deliver more current, ... Until someone tries to perform a load test on it. Then it can deliver more current than the wiring was designed for.
