sleeper?
I don't think you will really retain a sleeper look with a ram air hood. I switched to a ram air hood and air box on my 95 Formula cause I like the look alot better, and the stock hood had some minor hail damage when I bought the car.
I doubt that the HP gain from ram air is much different than a good CAI.

if you take the baffles out of the ram air hood though it starts helping a lot earlier than 70mph. I just drilled out the rivets on mine and took out the baffles, and theres no way you can convince me that ambient air isnt going through those intake points until 70mph. http://www.lmperformance.com/2386/1.html thats what im going to put on my car here very soon. completely sealed, pulls in only ambient air through the ram air vents.

Example:
If the engine is pulling air through the intake at a velocity of 70mph and the car is only going 35mph, then the engine is drawing air at a velocity faster than what the ram air can supply. Accelerate to 70mph and the air flowing through the ducts is only matching the velocity at which the engine is drawing it in. Only when the vehicle exceeds 70mph does the ram air velocity exceed the velocity at which the air is drawn into the engine under it's own power and begin to pressurize the intake. Even then, it is only a fraction of a psi.

If you want the awesome look that the ram air hood provides, great! I personally like the way the hood looks and that's why I'm searching for a WS6 over a base T/A (and the fact that I want an authentic WS6 and not just another clone). But, if you want performance, the ram air hood isn't going to net you any gain over a nice CAI. My '95 Z28 beat my friend's '97 Ram Air time and time again when we were both bone stock and both had A4's. Mind you, the sole reason for that was my car was nowhere near as optioned as his was and therefore weighed a lot less.
To put it simply, Ram air (and the old cowl induction on the chevelle ss 454) was nothing more than a marketing gimmick.

I cut my baffles out, moves more air now, ram air works, if anything gives you the cool sucking sound from the front
