Your asking us to choose pulley guidelines is like running a shelf tune...

run a small pulley and see how ur car likes it and decide to go up or down based on that!
Well there's really no ballpark guidelines for e85 and a gen v blower which are two things that drastically change what size you can run. So I was really just asking people with experience to get in the ballpark so I didn't have to buy every pulley from 3.6 down to 2.8. Start with a 3.0 and go down if I can.
