What mods do you have to support a supercharger pulley that small?

The biggest problem with adding a 3.0 - 3.25" SC pulley is knock retard (KR). You'll have to run colder spark plugs (two ranges). Intake and exhaust mods are required. A re-programmed PCM module from DHP or ZZP will be needed.
Otherwise you will damage the engine and due to the PCM changing advance and timing when KR is detected the car will run crappy.
3.4" is the safest pulley size you can use without the required mods. All you need to do is go one range colder on the spark plugs.
