I know it's possible to produce low amounts of "boost" if you have a tuned length intake manifold. The problem is it only does this is a small power band, but with VLIM you would effectively be able to produce 2 of these hot spots.

With that into consideration, wouldn't it be pretty beneficial to N/A people to have this effect work for them right before going into VTEC and the again at the end of the power band of VTEC?

The way I see it, if you could engineer the boost effect to just start to trial off when you switched cam lobes I think it would produce a good amount of power down low and maybe even help to move the VTEC switchover a little higher because of the extra power being produced by the IM being in positive manifold pressure.

All money and engineering aside, does this idea sound somewhat sensible to do, or does making a IM like that cause you to low too much power everywhere else in the power band to make it useful like I'm trying to describe?

 

do some research on the second harmonic. it is the strongest/broadest
