However the banshee was lacking any decent RPMs since i changed the setup last time, although it picked up torque. Even though its a better setup it bugged me it just dropped 2000rpm so hopefully that can be retained with yet another configuration change.
Got a blank squish dome made by lisci racing from Bollins racing and ground out a HSS lathe tool blank into the shape of the combustion chamber from a bzm dome (thanks to Allan from bollins racing on that one too) and made a new dome from the blank followed by giving it a polish with some 800 grit wet and dry.
Wont give away what the squish and compression is but its allowed the port timing and compression to be adjusted so that hopefully the torque will remain and the revs will reappear :) hopefully i can quantify the change its made soon!
