I'm going to reopen this thread as I've been strongly contemplating the purchase of a ram air setup.
The link to the ebay thing is dead, can anyone post a new link? I assuming it's some sort of safety device???
A 2 duct ram air setup is favorable to a 1 duct for the reason RM stated, one tube hits a puddle, the other doesn't and you get no water in the engine, just air. The effort to pull water up the tube is far greater than to pull air from the unobstructed port.
Now, what about rain water in a heavy squall or, say the wheel spray from a semi on the highway? That scares the crap out of me, running a true ram air setup.
RM, did you ever use the Indy on the street in rain running that setup? I can't help but think I'm wasting HP by running a round filter in a hot engine bay.

I think this is similar to what the link went to: http://www.autoanything.com/air-inta...A3167A0A0.aspx

RM, thanks for the heads up, I'm a bit more confident ordering now! You said you got your tubing at the HD? is that the firm dryer hose that keeps it's shape a bit? Any trouble sealing the setup to keep the air in and "boosted"?
Fergs, Thanks for the link to the bypass, I might put that on one side of the tubing for an accidental splash of water. I am a bit concerned it'll leak "boosted" air, but perhaps the pressure is all in the plenum up the tubing, hence the desire for a larger plenum.
Perhaps a very thin piece of foam or screen over intake tube would keep most the rain out, or perhaps mounting the ducts in the radiator flaps instead of the fog light tubes would give me some air pressure but not direct rain hit. I'll have to drive out in the next rain storm and check those flaps for dampness.
