I know that.. I was just wondering if he was going to build one since he'* interested in VLIR.

This might get kind of long but this is what I was planning.
A couple years ago my one friend got a mevi (resonance tuned) uim for is vq30de. Since then I've be looking to try some kind of resonance or variable length setup on the L36. Mainly, I've been reading/researching about resonance setups though.
I wanted to try and calculate a runner length that would give me a ram effect around 6k or so. I planned on putting a spacer between my HVII and the LIM and modify the fuel rail, alt bracket, hood support, etc, to make the correct length fit. Well, I have about 5 different formulas in excel that all generate different lengths. This is after researching numerous online sources, a few SAE papers, and 1 book. There is one other more recent book I would like to read on the subject but I'm going to have to wait a bit since its $200. I'm not satisfied enough to mock something permanent or manually adjustable up yet.
I want to dig deeper.
And that is just with the intake runners.. There is also ways to take advantage of resonance between separate banks. The vg30de, vq30dek, vq35, porsche gt3, and plenty other motors use this.
With all that resonance stuff aside I would also like to try and mock up a variable intake of some sort. Since I've never done anything like that I don't want to jump on a continuously variable setup. I can think of more than a few ways to make one work looking at current setups but actually fabricating it is another story.
A dual stage intake seems like a more realistic approach to me. There are plenty of ways to go about this as well. I could make it so you would never know its there using stock parts, I could go completely custom, modify a setup from another application, or do a little bit of each. I still have plenty of research, thinking, and tinkering to do before I attempt anything...
Still curious as to what Hector did too.
But he||, I don't even have a car to try this stuff on yet.

I have an L36 UIM here for the sole purpose of figuring a way to do this. I think I have a simnple method. Won't be continuous, but the runners will change length at a given manifold vacuum level.
