This was probably discussed before but I could not find the thread.
I just had an Air Flow Performance Injection installed on my Lycoming and instead of a filtered air box my buddy rigged up an unfiltered cold air intake with a filter bypass for ground operations. It looks like a slightly less tall air box with the same basic violin shape....just no filter to impede air flow.
So my question to the horsepower guru's out there is.... Does this setup increase HP significantly by taking away the filter resistance to direct air into the system? That is the idea of course, but has there been any testing done to prove this one way or another?
Should the shape be the same "bowl" as a FAB? or should it just be a snorkel-like inlet?
Does there need to be a ramp in the violin bowl directing air up into the vertical intake? or should the ram air be allowed to just "pool" in the air box?
Any thoughts or recommendations are appreciated.
