What Is The Smallest Pulley I Can Run Until The Supercharger Snout Needs Turning Down?

The 15 PSI (2.9") pulley is the smallest pulley you can run without having to machine down the end of the snout - to run our 16,17 or 19 PSI pulleys you will need to machine down the snout.

We have a snout machining tool available to do this, which connects to a common power drill and makes snout machining a 20 minute job for even a common DIY enthusiast - http://www.maceengineering.com.au/epages/shop.sf/en_AU/?ObjectPath=/Shops/mace/Products/PLY612/SubProducts/PLY629
