k i finally have got the itch to add some serious perfromance to my 93 sc i know everyone usually does the exhaust then o/d pulley but what i waan know is is it better to port the stock blower or just slap a pulley on it i do plan on doing the exhaust first true duals of course
im looking for efficiency not insane boost numbers like isn't better reliability wise to port instead of the pulley
thanx in advance

With a good true dual system you will loose some boost, as you would with any exhust system. I would add a 10% blower pulley and add some sort of cold air intake. If you have the money, then I would say to look into the many ported blowers that are offered. Or if there is a machine shop around you, then give them the blower to replace the internals, and port it for you. Also you could check out magnum powers site, they ahve blowers, embree specail amchine, they too do blowers. Well the list is big, check out the many o the net.............good luck the upgrades.
