Jim,
I think it would be a little small, it might make the boost your after if you spin it fast enough but you will lose alot of your efficiency in the process. I have been running a littlefield 8-71 that's stripped and I'm making 17-20psi at 45-60% over depending on the air. It sounds awesome but a 14-71 would make the same amout of boost at 19% over without heating the air as much.
