I have a 2.95 pulley on there now and wanted to get a ported blower. When I do this I want to put a 2lb lower on it. Now with the 2lb lower do you think I am going to peg my maf or need a boost-a-pump? What about a 4lb lower? The reason why I ask is becuase after I do my clutch flywheel and 26 splin input shaft I would have enough founding to get a lower pullet and a port but probably not enough for a boost-a-pump and some sort of maf extender. I guess I could just wait a another month but I need more lol.
