I'm still here. Just got the engine up on a stand last night. I'll be designing the front bracket today and tomorrow. That'll give me a starting point for the manifolding and front volute design. also the belt drive and rear bracket.
All the little hoses and vacuum hook ups. Smog stuff has to be figured out.
Oil feed and drain back system. Looks like we may cast a new pan so that we can get proper drain back.
So there is going to be more pattern work then I thought there would be.
I'll keep you posted as this goes along. It will go much faster now that I have an engine on a stand.
There is yet another new blade design about to be cut. That means another set of bench tests but we are that much closer to the right flow.

Not criticizing, I'm no expert, just curious. Thanks very much.

doh! did you have to fab an adaptor to mount the engine to the engine stand? i actually have an extra one i have no need of sitting on my workbench. i won it at a raffle. its one of these from pineapple racing-

Thanks for the update Richard. Was just curious as to the goings on over yonder. Maybe I missed it, but what happen with your car? As far as getting Mazda to do anything about it?

I realize the goal is to have a perfect fit supercharger for the RX-8/S2000, but have you ever thought of making different sizes of these things for people who want to scale a bit for engines that have been ported to flow more air or do these things just flow so far beyond what we would need now that the potential is already there and could just be unlocked at a later date?

watch out for that adapter. it doesn't push the engine out far enough, so dropping the intermediate is an absolute BITCH!!!
you should be cool if you use about 1/4" worth of washers as spacers between the adater and the engine though. but i usually use a 5 gallon bucket :D

That would just show some bldes are longer then others, you cannot see the changes in geometry with your eye. In fact each stage is a different size and shape. They get shorter going back. Plus a whole bunch of other things about the blade change that are invisable but important.
Ajax, there will be excess flow available in the design. It just isn't the best thing to do to make one size fits all. This is basicly a wing machine and need the air speed and AOA to match what it is lifting and how fast it goes. To make it worse then just a wing it has close turbulence from it's static stator blade and the twist from the prior stage. Then you need the stages to work together and in the case of our unit it has to work off design most of the time.
It's a challange to get the right combination of things to work with an engine which becomes a positive displacment reciever for the exiting air.
TexasKyle, They never gave me any satasfaction on this and I guess as we go along I will find it myself. If I never get it fixed It's just the right color, I'll have the painter detail like a lemon and park it in Orange County.
About that bracket, no I didn't need to build to much to get it to work. It just took a set of bolt on fingers from an old stand put to a new one. They had the adjustment in the fingers and were deeper. So deep that I couldn't find bolts that long in 1.25 thread. I had to get threaded rod and make studs.
Thanks anyway Zoom. Give it to RG. I'm sure he'll figure something out.
If I forgot anyone post again and I'll catch it.
As an update, I got the posterboard cut out of the front bracket done last night. As soon as my computer will let me draw I'll make a solidworks drawing for the shop. Then it still takes some 3D parts added to it which in production will get cast. It should get a first try bracket and mounted this coming week. When it gets mounted I'll take pictures.

Richard, many of us are going to be in Irvine October 7-10th. Sevenstock 8 is on the 8th. Get a mockup in the car and show it off! It doesn't matter if you don't even have a belt on it. Let's just see it.

No, do you? Hell I'm just happy I can draw a bracket. That's not true I draw the supercharger. That is something that comes from my head though not an engine I would have to copy every detail and do an assembly drawing. That is a lot of work, someone would have to be paid to do that.
RG, that couldn't work because all the manifolding is changed. I'll try and get it on the engine though. Do I call someone to get a spot to put my engine???

If you can get it in the car just show up, get in line with all the other people looking to park their car on the grounds, and just open your hood up. That's all Pettit did last year. They didn't set up a booth. If you want a booth or a spot, you will have to ask someone. Try talking to Bern at Rotarynews.com. He might be able to help out. You could also see if Racing Beat or one of the other people would let you have a corner of their booth as well.

Fred - ill bring the engien stand adaptor to 7stock
Richard- if all else fails and you have it in the car drivable by 7stock just show up. even if you arrive a little later int he day im sure one of us that is in and has a spot early wouldnt mind moving to give you the space.
Also i asked around and have not found a SEMA connection yet.
