If you use a thicker head gasket, you might be able to knock it down a little bit. I was talking to Mark a while back about developing a kit for the Nail. My motor, as it is setup currently, is about 9.3:1 or there abouts. I think we agreed it would safe to run 4-5psi. Just something to think about.
I was considering that too. But the thing is I just wont financially be able to complete this project.
