Default smaller pulley?

2000 Bonneville SSEi

I would like to get a smaller pulley on my supercharger soon and was wondering what size pulley I should be most inclined to go with.

I was thinking about the 3.6 and would like to know if this would be a substantial yet safe increase in boost.

Also wondering if I put this smaller pulley on do I have to get a new tensioner pulley that is bigger? Or does the tensioner itself have enough play to take up any slack that is created?

Also i havent checked 4 kr yet.

Hope I can get some guidance!
Thanks, Anthony

Your stock pulley shoudl be a 3.8" And you shoudl be able to go down to a 3.5" safely. Soem cars can drop to 3.4" but I dont suggest that. You shoudl also look at changing your air intake if you haven't already. Changing your thermostate to a 180 woudl also be a good idea.
