Yep, width too. Take a Frisbee out to your engine bay and see where the heck you'd mount it...actually, take two and put them together like a little flying saucer type thing...the DC pancake motor is the same size.

thats pretty darn cool. Your giving me some pretty crazy ideas now, like, how many can we fit on a given engine? not necessarily a rotary 
or maybe we could put one on a motorcycle...
yard tractor?
lawn mower?
the possibilities are endless!

hey i just got done reading the whole thing and i have to say that i am pretty interested in the whole idea. earlier on u were saying that u were gonna do something along the lines of a turbocharger with this tt design. are u still gonnna do that? cuz that is what i personally would be interested in. somnething that is jsut like the turbo i got now but a whole lot more efficent.
a little bit back on another forum a guy came up with the same idea for a turbo. at least how i understood that and how i understand this to work i think is the same.
http://www.teamfc3s.org/forum/showth...&threadid=3926
http://www.teamfc3s.org/forum/showth...&threadid=4102
so what i am sayin is i want something that runs off of exhaust and creates boost vz ur bladeless disk thingy. is that possible? and if so si there a timeframe or are u even going to do it?

Well, like I stated before - I am a firm advocate for electric drive vehicles. Tesla was as well. Electric drive also gives you instant torque at start-up. For now, we'll concentrate on giving the Wankel one hell of a boost, after we see what happens...who knows. With a propane power source, the turbine would be more than adequate at powering a generator/AC electic drive for the RX-7 body. That's something to play with some other rainy day, for now. Supercharger - that's what we're working on this week...

so, yes you do have an option for your 12A.
but, this is getting away from the topic of this thread and should be discussed somewhere else.

I am afraid you be getting too gradiose too soon. just to get the thing working don't worry about RPM sensitive, or belt frive or anything like that.
for starters just hook a sylinoid to a switch on the throttle body to sense when Wide Open Trottle is achieved. You can use a switch for a nitrus kit. just a few dollars.

so basically i'll be able to get a conservative amount of boost with big hassles? no maitenence? and no dent in reliability? driven all by electricity!? am I reading this right?
Tesla was a genius.

dam skippy, just posting to know about progress frank, what have you come up with so far, and what about price ranging, discounts for rx7 forum members, for tesla turbine list? And maybe if if will be strictly bolt-on, also, what are the words on nitrous? would it cause any problems?

I would have to agree with some others and for a first round just go with on at WOT. This would allow for testing of different boost levels and built in safety since the unit will only be providing boost when your foot is on the floor.
Final version.........much more complicated.....based on RPM, load, throttle position. Maybe start with a curve similiar to the turbo (steeper of course) and go from there.
Keep us posted, this is very interesting and I'd love to see some pictures.

i don't like the idea of having it active only at WOT. i think it would be better to have it read off the RPM signal and give the pump it's RPM cue from that. That is how current supercharges work after all. why make things more complicated than needed?

Superchargers on rotories suck. but if this is as good as you say build me a 23 psi 1200cfm unit and ill compare it to a turbo of equal performance. It just kinda sounds to much like the old "supercharge any car for $69.95 gain up to 35 hp!" If it works more power to you, but untill then I think ill stick to tried and true turbos. Good luck

So, explain why a supercharger is no good on a rotary? Your going to need to back that statement up. Have fun!
Iv seen that "supercharge any car for $69.95 gain up to 35 hp!" thing, thats so funny! they call it the tornado or somthing. All it is, is a piece of bent sheet metal! The person that made that should be shot!

no he's talking about the electric superchargers that you find on ebay. but all those are modified computer fans .
when you get right down to it, rotaries love boost (period). they don't care if it's generated by a belt or spent exhaust gas. either way you will see hugh improvements in performance, which is what most of us NA guys are looking for short of going out and buying a TII.
Personally i'm just looking to add a little more punch to my 7, not to shred the life of my engine by trying to pushing 23psi through an NA. but if that's what you're looking to do, more power to ya.

Hey Phu5ion,
I'm right there with you. I have a '88 convertible and I'm looking for a few more ponies added the smart way. I made this car my daily driver because it's fun to drive. Keeping things simple, maintainable and reliable keeps me from having to repair it every week.
Enjoying this thread!
BTW I'm in!

I have to admit to not having the greatest understanding of electronics, but couldn't you just use an electronic boost sensor to drive an amp circuit with a potentiometer to calibrate the boost pressure you wanted? It seems like it should be a pretty simple way of replicating the constant torque curve of a Roots-type blower. Just set for a specific boost pressure with a **** in the dash and feed more or less power to the electric motor to maintain the pressure, right? Seems like it should be almost as easy (and a lot safer) than having the thing come on full-tilt whenever you hit WOT.
