I see your picture.

How would there be more air turbulance after you removed the butterflys as opposed to when it is functioning normally, and the butterflys were open?

When it is closed, the intake passages are longer, and provide the low end torque, and when it is open, it's tuned for more power at a higher RPM. Very cool I think. Apparently you need to build the bushings for those butterflys out of a quality material or they will kill your motor upon ingestion.
