8 is more hp... im not sure that there is a hp per psi gain formula.. i think at 2psi you have 1.5 times as much hp as 1psi? or something along those lines... someone correct me if im wrong

too many variables to determine. But if you go with an afc and 450's for management, or 450's and a chipped ecu you will be safe for around 10psi, so 8 would be fine also.

Ok this is what I read somewhere,
1 bar is suposed to be double your na output cause your doubling the amount of air entering your engine. So if your doing 7psi which is aproximatly half 1bar, then youd be adding approx. half of your na output.
Something like that so it depends on your na output as well as your boost level.
