Here Is A Thought I Thunk
#1
A few things together gave me this idea - tell me what you guys think of it. Start with a S5 six-port. Bridge-port the auxiliaries, street port the main ports. So far, nothing that hasn't been done. But then, take the rotor housings and cut small peripheral ports into them, like Judge Ito's semi-peripheral port Cosmo. (That was a Cosmo, right? can't quite remember.) Use Pineapple Racing sleeves for the auxiliary ports, actuate them with an rpm-sensitive switch controlling either solenoids or an air pump. Then, for the peripheral ports, have another rpm-sensitive switch, set a bit higher. Make the manifold so that it has controls for the peripheral ports. I'm thinking gutted carbs off a small motorcycle. Just something that would be the same inner diameter as the intake ports going to the peripheral ports.
Nice streetable low-end, civilized idle. Screaming top end. Yes? No?

You seem to have the right idea. If you work really REALLY hard and every fiber of your being wants it to work, and you're willing to get away from the KISS ideal, and you want to spend enormous amounts of time, energy, and money on something that may not even work right, then yes I think it could be done. It would be a one-off that would be difficult to reproduce due to all the customizing, but it is possible. I say go for it, but only if it's for the right reasons. I love cool rotary projects.

Why... I'll be. That's sort of exactly what I'm planning to do. Minus the pineapple sleeves; I think I may have a better actuation method. Oh, and not necessecarily RPM sensitive; I'm building my own damn fuel injection computer, so it's an easy thing to have it be load sensitive, for example. Or some other combination of factors... I'm going to wait a while on figuring out exactly what. The engine build is going to come first.
Time, sure. Energy, of course. Money... well, if you don't have friends with fabrication skills...
I'm hoping to at least get it started by the end of the summer. It might take longer than that though, due to the fact that I'm a poor-*** college student.

mazda toyed with this in the late 60's on the 110 cosmo's. they ran off the primary ports and then switched to pp for the secondaries, notice how it hasnt been used since? well actually i guess scoot has had good results with it
