Hey davey, can i ask if your using the BOA or BOB engine?
I'm currently building 6 individual butterflies for the BOB (would say throttle body but the injector is in the head) Using 45mm butterflies as the cross sectional area is just slightly over the head port size so as not to cause any restriction and they were also what was available at the time.
I prefer torque over high rpm, hence 2.9 V6 cosworth engine.
