I have been browsing some sites trying to figure the flow rates of some options for turbo upgrades and no 2 sites have the same info. Some have stated that the VF30 flows 550cfm while the VF22 flows 500cfm, another site states the big 16g and VF34 both flow 550cfm. WTF??? I am going crazy trying to find a bolt on turbo that flows ~600-650cfm at around 16-18psi and NOT be past its efficiency. I read on this site that ALL IHI turbos flow under 500cfm in that psi range . ANY body elso come across this conflicting info??

Also is this thread correct in the CFM?

Also any links to the IHI compressor maps as well as FPGreen, 18g, 20g, 16g, and Big 16g?

 

looking at this compressor map:

it seems that the 18g will meet my flow needs and still have some room for increased boost. Is this the correct compressor map?
