i've seen many people run that combo without a ported blower...how would just the 2.93 upper and 4 lbs. lower go, would it be too much for a non ported blower???, I have my dyno tune comming in a week (29th of this month) I might not have enough time to install the blower and all the pulleys!!! I should get my blower back on Friday of the upcomming week!!!
