Jim, would the tuned intake be like a 4-2-1 exhaust in reverse? I've never heard of such a thing.
All the runners are the same length, and the length determines the resonant frequency, kind of like a pipe on a pipe organ. The longer the pipe the lower frequency. Since it resonates, it has higher and lower pressure waves bouncing back and forth down the runners. When the higher pressure pulse coincides with the intake valve opening, the cylinder gets more air than it would normally. But it's a fairly narrow band that this happens at.
sorry i wasnt paying attention there... Im still interested in this thread as ive been messing with this kinda thing for a while now...
gasser exhaust mani has noticable gains forsure
Would there be a way to remove the air filter and seal up the big box...run a CAI or ram air system and use the stock N/a diesel intake as a air chamber expansion tank...
as described in this vortex thread apon a gasser rabbit

There would be no reason to have an expansion tank I could see. You need quite a bit of speed for ram air to have much effect as well. Having a lower mounted intake at the front of the car would worry me in the rain. One good puddle splash is all it takes to hydrolock your motor.
An IC is a waste on a NA car. I guess the bypass might solve the water problem, but it seems like it would be restrictive. A Y type valve would make more sense to me.
