Lets see if this works. I had a spyware attack today. Bought some killer disc. Killed the spys and now a lot of stuff doesn't work.
Looks like it will work now. BUT I can't get the pics in. Says they are too large. Someone tell me how to make them smaller.
Help me out you computer gen guys.

=Lets see if I can give some comentary on the pics since they were relayed through Ajax.
First pic is the gearset. here you can see the four pinon drive shaft/ cage ***'y. notice that the pinon gear is mounted on needle bearings.
next is most all the componants less hubs and shaft spread out.
unit mocked up. showing size relative to tissue box
volutes and transmission housing.
Transmission housing with gearset and drive pulley installed. Note that the pulley matches the Mazda 5 groove belt. Also that along with the snubby housing the pulley is reverse overhung to reduce size.
These are the five stages of rotor/stator. Notice the zero clearence stator tips (Patent pending)
I'm going into the shop now and will ***'bl the blower. Get some more pics and post them tonight.

Man that looks like one expensive blower. Also, you said everything is made from solid. How the heck are those stators made from solid?
You know what would be cool? Change the planetary gearbox to a CVT. Then you could keep this baby on full boil all of the time. Never another argument on boost rise or whatever.

Well I'm back from the shop now. Put the compressor section together, all went well. When I went to put the housings on I realized I had forgoten to cut the lybrith seal. When I get mad at myself I stop building things as screw ups come next. So when I feel calm I'll go back and do it.
Lets see if I can answer some questions.
Babylou, Yes it is true, every part you see in the pictures was cut from solid bar stock. several different alloys but all billet. The stator is trick enough so that we have applied for a patent. As to the CVT, a few years ago ZF claimed they had something that would work with my compressor. We never actually touched bases but there was some around the back comunication.
I haven't thought about it since. My feeling is that it will cost more then the blower.
Yet if someone in the buisness of building cost no object cars????
Wakeech, there is a passage system with orficed bathing for the gears and bearings. Rear is greese only. This uses engine oil. It could also use it's own dry sump. I do that with high end race or off shore blowers.
Really,
Velocity 8, Didn't need that thought. Excuse me while I go poke my minds eye out. Just kidding, good to have humor, very good if you work on cars. you usually wind up needing it.
If I missed anyone tell me and I;ll answer if I can.

Couldn't any typical piggyback ECU do this as well? It would have to be able to read a pressure sensor, but for instance I'm pretty sure the Canzoomer hardware was set up to do this when the kits become available.

Richard Paul,
Man, this is looking good. Couple questions during your "down" time You dont have kids do you? LOL. I was reading (forgot what turbo thread) that the composite intake we have is actually EXPANDING during acceleration! Is this a concern with boost applications possibily making a new intake neccessary? And question # 2 Are you far enough into the mounting/placement design to know if the engine cover will be retained? I understand it helps the airflow under the hood. Heat is a factor here. Yesterday on a 84 degress georgia day I measured the ecu box temp and after a normal drive of approx 30 miles at the speed limit of 65 it was 138.7F. I think thats hot for electronics.
Keep up the good work man. I think you are the most serious FI project I have seen.The community of the 8"s await. If you are sucessful then you will be THE person that has unleased the beast!

Olddragger, yes I do have kids but they are both out of collage. One is the chief solid modeler for Lucas Films making Starwars movies the other is an engineer at Boeing.
So they arent around much anymore as they don't even live close by. My older son, the engineer worked with me on the supercharger before he went away to school. The other never liked working on engines, he was always the artist. Went to Art Center Pasadena. And never turned a wrench again.
There may be hope, my grandkids are racing go karts.
No, if in fact there is something going on with the intake it will have no effect on our installation. I doubt that it is really expanding though. There is no reason for that to happen. If it were do to pressure drop it would have to be one really thin section. I don't think they could mold it that thin. It can't be temp change as the composite doesn't transfer heat well.
I am aware of the under hood air flow problem. I really don't think it a problem as some do. I have more confidence in Mazda's engineering then that. I used to worry about the electronics under the hood and it is alway better to keep them cool, but modern products seem to be much better at it.
I have heard about some coil problems and would like to know more. However I am going to be sure it is taken into consideration. Your temp reading does not seem to high for what my opinion is worth. The biggest problem is heatsoak after you shut the engine off. Then there is no airflow and the heat starts to even out to all the underhood componants. that means if the block is 250 it starts to loose that heat and it goes into other things. So your temp mesurment is not going to be the peak that part will see.
It's the same for the supercharger, it has air going through it when running. In fact it has air at reduced pressure so it is cooler yet. When it is then shut down it will obsorb heat from the engine. Therefore we must allow for heat effect to that level.
