Understanding pack

[CARB]

Hi there

This aimed at the beginner and the expert. for the beginner to know and the expert to explain.

I have a understanding of what it is and how it works but would like to know exactly.

My first question is when is pack important to use and when is less needed.

My second question is do small holes mean more pack and does having less holes have the same result.

Hopefully this will help everyone to get their cars handling better.
