What is the stock VF setup for our cars?
- psi of stock kit
- crank pulley diameter (confirm please that M54B30 is 5.185")
- supercharger pulley diameter

I know that using this:

You can start to dive into alternate pulley setups.

- Is my understanding correct that the M54B30 should be able to hold 8psi reliably?
- Can the VF kit handle this as well with a smaller pulley?
- The impeller speed is given via Vortech but how do I go back to determining pressure?
