nice post you just explained why I and most of the people on this forum are eagerly waiting for you to do the hard part, so we can just bolt it on and zoom zoom.

Actually I want a new aluminum upper manifold for forced induction use. Putting composites under pressure scares me.

RG, I'm sure you can eat and drink with the best but for now I ment 1 b.
As to the manifold you will probably get it your way since the molds for a composite part is way out of the question for my volume of parts. On the other hand I'm not sure that it can't take low pressure. If there is a way I can keep it in the loop then we will test it for pressure and temp.
If anyone knows the exact material we can look up the numbers for it. It would tell you if it is worth testing. I've worked with engineering polimers that are almost as strong as aluminum. This is not that exotic of a composite but where it is should be studied

I have learned the very hard lesson not to think you are so smart that you can go into another man's area and beat him...
... Think about that, one tiny car company with limited resorces is the only place this has been studied... [Way to go, Matsuda!!]
...alas you can never go home again. . Everything on the car from the time you open the door is in that black box. In the end of course we are all better off for it but I can still complain. There is no way the power and reliability of modern engines would be possable without the engine managment systems. In racing as well as road cars.

I'm not very patient but I don't know anything about tuning rotary engines so I am forced to wait. Take your time and I will gladly give you some business when you get your system out. Nobody else has anything that is functional at the time so your not missing business opportunities. As for the giving up my car thing, I want to sooo bad, but then I think about worst case scenario and shun the thought. It really is a hard argument but I love to drive too much and don't want my car too many miles away.
Keep up the good work!

So before we take a perfectly usable car and reduce it to a lot of little parts on the bench we need everything else well along if not final.
If you want I will take your car apart and start fitting things while we do the rest of the development. I just can't tell you when all the other things will be done. Or if all the problems will ever be solved. That is when we will put your car back together. If you can live with that I will entertain taking it off your hands.

Just when you were ready to go back in the water!!
We needed a little more airflow then the first prototype produced.
That by itself wasn't a shock, we allowed for that.
But if it can go wring it will. After some close study there is a need for some passages to be reworked. This is to keep the airspeed constent.
This is the exit volute that has 5 of it's 6 sides machined. So it is a time consuming rework. I should say redesign as it cannot be reworked from an existing part.
These are some of the things that the axial flow compressor designer must pay closer attention to then say a positive displacment pump.
Just a little more work. Work, work, work
Don't know how long it will take. Design this week, machine program and manufacture, another week maybe two.
Anyone know the size of the throtle body on the RX 8???
Area and airflow at some pressure drop.

Sorry, my server has been out for three days now. Update: I just finished the new blower yesterday. It is a five stage with more flow and some bending of the curve. Have not tested it yet. There is an identical four stage unit being built also. That is what I am working on right now.
When they are both ready and the time and space is available the tests will get done. I'll see if I can get some pictures of the first and second models side by side. We shall call the newer one dash 2, so as to be sure of the evolution.
Also someone wanted to know the weight, it is 11 lbs +/-
Hope I didn't leave out anyone.

just had a crazy thought (thanks to shelly's man)- could you combine this axialflow compressor with a turbine and make it an axialflow TURBOcharger? would there be any benfits or problems?

cool!!! i knew there was an invention in that thought somewhere!! do you think i can get a patent on it?
i would give you credit for naming it, though i think it was rather presumptuous of you to go around naming other's inventions :p do you think their would be any applications for this "jet engine" 
p.s. - "jet engine" is already taken we will have to name it something else :D

But I did mention this concept, and asked if it had been in automotive use in past # 212 (page 15 of this thread):
https://www.rx8club.com/showpost.php...&postcount=212
Near the end I mentioned some day dreaming during english classes about this...
Did you know a jet engine idles at about 60% RPM ??
For an interesting read, go look up the work Chrylser did on the Turbine Car.

well as i said "jet engine" is already taken so we'll have to come up with something else to call it 
you know i had read your post but had forgotten until just now. perhaps there was a bit of it left in my brain when i had this epiphany earlier. so could this be driven by a turbine instead of a belt?
