Best Bang for the Buck Head???

" Now do you believe 30cfm/60 hp potential increase for 400 bucks isn't the best bang for your buck"

Something there's inflated - and it's not the buck...lol.
Te "2cfm per horsepower" is biased way more to purpose built race engines - not milder engines. This engine wouldn't get 60hp from 30cfm more without some serious work and parts changing.
