what a nice job on your air ram. i think i will also add a second intake and put one on the other side too. i run a K&N air cleaner. i keep it clean and lubed. the K&N really made a difference. i currently have a ram air thru the grill, bit i know its not big enough at 9 sq. inches. a 4 inch hose has 12.5 sq inches. 2 such rams would give me 25 sq. inches of air flow. that should really help.
