At 6psi with 440cc RC injectors and Hondata I have a 12.0:1 to 12.5:1 all the way through the rpm band and I'm only running about 60% injector duty. I could easily handly 9psi at about 80% duty cycle and run an 11.0:1. I'm not sure if I could run the stock fuel pump with that setup but with the Walbro it isn't a problem. At 12psi it might be a stress on the injectors to get to an 11 A/F ratio. I do agree, that if you want to run over 9psi then a turbo might be the way to go. I don't even see myself going to 9psi for quite a long time if ever. I'm very happy at 6psi right now.
