I'm just stumbling trying to figure this out.
Ideally I would like to run the manufacturer suggested 5lbs of boost to start off with. My engine is a 3.2l stroker. To be exact it's like 3.1957L I believe.
My drive pulley is 18.85" in circumference. I can't for the life of me come up with a formula that makes sense to me. So please feel free to dabble with this and let me know if you can help.
If you click the Blower Drive Ratio Guide PDF, It contains what is the formula fageol suggests to use to figure out the output of the blower. I could really use a hand figuring this out. Any and all help would be appreciated very much.
