I know the numbers aren't right I couldn't be bothered, it's the theory that I'm after. So here it goes. If our stock injectors flow 235cc @ 43psi, then the purpose of running the 110psi with the turbo is to make our stock injectors flow at say 500cc to compensate for the boost. So if I'm right on the above then if I get 440cc injectors then in theory I can run the fuel presure at say 55psi, which seems alot better to me then the super high pressure with the stockers. If this is right then what does each boost level need interms of fuel flow eg. 500cc @ 8psi and 600cc @10psi of boost. Because If this is right then wouldn't we have to reconfigure the fuel pressure for our own boost level and injector size. Also does this mean that HRC's external pump isn't neccesary any more(this is based on an old post about fuel pumps) making the intank pump the way to go.
