Another thing I was thinking might work (but only if you use longer runners) would be an enclosed ITB setup, like the RB26 engines have. That way, you can still use intake piping to feed the engine while moving and keep velocity stacks on each ITB. Best of both worlds in theory, but it should (again, in theory) be close with resonance to a stock intake manifold. I think with that kind of setup, you will still be able to tune and improve airflow using different size and length velocity stacks and utilize the ram air effect from your bumper mounted intake pipe. I know this could open up a world of new obstacles to overcome, but I know that a setup like that can net more power than a regular styled manifold. If it works for Nissans, I don't see why it wouldn't work on our cars. Peak power may be sacrificed (if at all), but the powerband may be broadened and allow the car to pull harder through more of the rev range. Again, this is just my theory. Yeah, my work day is going good enough today to allow me to think about this...
