This a bit of a continuation from both the head mods and flow work so the first few pics will be re-post from those sections to give you the starting point.
My first thought as to use Suzuki Hyabusa TB mounted to a cross-flow intake
and it looked good in theory. This would mean curving and flattening the intake runner to make the crossover work but it seems doable….until the flow bench said I really needed bigger TBs
I played around with a test runner from clay and then a chunk of aluminum and the TBs will fit but the ports need to move up in the head to make it work right…..off to the head re-work thread
