Thought this would make a good non-political thing to talk about. We have blowers of all different sizes,14-71,12-71, 8-71, 6-71, 4-71 and the list can go on and on. Considering the power it take to turn one what would be the best sizes to use on different cubic inch and boost levels. I know how I have always done it but would like to hear the smart people talk. OK Bob. What you think.
