I have a Vortech V1 and am going to add an A/A fmic. I currently have the stock 3.6" pulley and push 10 - 10.5 lbs of boost. Question is, what size pulley should I go with to get the approximate same amount of boost. I have read 3.125 and 3.33. On Ebay, there is a seller who custom makes them and has a 3.2 as well. Next question, is there a need to get a smaller belt or will the automatic tensioner be suffice for the situation. Will belt slippage be an issue and will I be putting my V1 out of it's efficency range with the smaller pulley?
