Couple of things.
Ram air setups can not be proven on a dyno (standing still and ram air don't go together). A 1/4 track is too short to gain enough speed to take advantage of a ram air set up. So you may never be able to confirm any gains.
The volume or air required to snake up the tubing is such that you would need to be travelling excessively fast to see any benefit- as Hector posted.
I think some people may be over-thinking the solution. I would be focusing on an open-element filter with a proven heatshield. If you can successfully shield the filter and allow it to draw air from the open fender space (behind the boot and tubing when you remove the airbox), you will likely have better results.
On the bright side, I don't think it will hurt anything (except hydro-lock if you run over a deep puddle and your car ingests water).
