To ram air or NOT to ram air?

I have done some testing recently on my ram air setup, and the results were interesting (at least to me). Here's a comprehensive run-down on ram air, how it has worked on my RV-7, and some recent flight tests and confirmations about the system's performance:

Excellent write-up Dan. For simplicity, I'm planning on just using the filterered air box. This confirms my choice. I just need to make that air path as smooth as possible.
