Default Re: Performance Problem

This may be a dumb question , but what is gained by elimanting the secondaries other than a slight bit more airflow??? Other than the valet function I thought the major reason for running a split intake is to run on the smaller cam lobes and have less runner volume - thus increasing air velocity in the runners and greatly improving low and mid range torque and hp and responsiveness?? Then as rpm increases use the larger cam lobes and the extra air and fuel, wouldn't this delete just screw than cool system up?

Not judging just asking for education, as an mechanical engineer I just like to understand these things about my car... Thanks for the reply
