Nice results!! I have a s trim right now that I will be putting on my built motor with heads, cams ect. I will try to push my blower to 15psi with a 10% OD crank and a 3.12 blower pulley. In the fall i might upgrade to SI to see how much i will gain.
That sounds awesome keep us posted. From what I've been told 15-16psi on the same trim s about its limit. After that it starts getting really hot.
