if your base pressure is 40 psi, and its a 1:1 reg then yes 48psi would be right at 8 pounds of boost, but whats right depends on how it was set up. base pressure may be higher or lower than 40.

what reg do you have?

if your not happy with the rising rate reg i would change it as it can be the down fall of the motor!! as for the fuel presure every pound of boost you have to add on to the fuel presure EXAMLE with a blow throw carb it runs 8 to 9 psi unboosted but if your running 20 psi of boost it has to be around 28/29 psi of fuel presure the same applies with fuel injection

Thanks I spent an hour reading about yours, nice progress you made over the years, I'd like to do the same but our local track is closed down.
I am guessing your talking about gateway? I heard that there is new track opening on north side of stl. you going to be riding in ROC this weekend?? should be mayhem... last year was fun.. I have been taking my 12 down there for 3 years now.. and so far have been only one i have seen.. but lots of bikes show up i could have missed one.
