with a w-9 head it is impossible to get 470cfm through a 2.8-3.0 minimum cross section,, it just isnt big enough,, period,, im tired of this stupidity,, nobody on the planet in comp, pro stock, nascar, or whatever has even came close to that number,, but i guess you figured it out

show me the timeslip? that sums it up? mr bwacked,, what have you worked on that has made 2.2 or more hp/cubic inch? for real
