Is there any guide or general know-how to tell how much boost a specific pulley is going to make?
Currently I have a 3.40" (or is it 3.48?) which I believe is rated at ~8-9lbs of boost. I'm looking to go up in size as the anderson power pipe I have is helping raise the amount of boost that to about 13(!!!)psi. I want to switch to a ~6lb pulley, order the methanol injection kit, get those two on there and get it retuned. I'm just unsure of what size I actually need. I'm thinking 3.6" would be sufficient, I just don't know what sizes of pullies reflect how much boost they make.
