Greetings, fellow rice burners...

I don't own a Honda/Acura, but I was pointed this direction by one who knows engines much better than I to get some expert advice on tuned intakes. He said GT-R/ITR guys were the best at it.

I drive an MX-6 and my question came from the fact that stock MX-6's (and Probes) have a Variable Resonance Intake System (VRIS) that "tunes" the intake manifold by changing its effective length at certain RPMs through a pair of shutter valves and bypass tubes. The theory being a tuned intake, much like a tuned exhaust, will improve power. In that way, the VRIS acts like a (very) mini super charger and there is a small but noticable boost during acceleration at 3250 and 4250 RPMs.

Well, I want to add a CAI, but I'm looking for advice on tuned intakes because I don't want to counteract the "tuning" being done by the VRIS. Else, I'd like to disable it all together, and build a precision tuned air intake to get the most from it and the intake manifold.

Is there someone here who can (is willing to) explain, in the most nauseating detail (go ahead, I'm an engineer) some of the principles behind DESIGNING a tuned intake?

Thanks,
Glenn
