OK, the design makes more sense if the stages are individually designed and sized. That wasn't clear from the photos, but obviously the last stages should be shorter than the first stage. I guess with such small pressure ratios across each stage it just isn't obvious in the pictures.
If the data shows that it works and you can make it cheaply enough to compete with the established kits already on the market, then I'm impressed with your design/build skills. But I think you will still have difficulty in the S2000 market, just because the field is already crowded.

As mentioned above - where will the power be most beneficial through the revs?
If it performs as good as it looks for the prices suggested on the RX8 site - they will come.

Yes there are dyno charts but no one will tell me how to post them.

The pressure curve on the Axial blower is a linear, meaning if it has 4psi at 4000 it will have 8 psi at 8000. Well thats the theory anyway. In real life it sorta works that way. I can make it bend somewhat. Plus the engine is eating it at different rates. When you realize that the manifold pressure is only resistance. If one engine flows better than another the one that flows better will have less pressure and more HP.
The roots theoretically has a flat line but again doesn't work exactly that way. Mainly due to leakage at the low end. The centefugal has an expotential curve, whereby it has 2psi at 4000 to get 8psi at 8000.
I'm reluctant to guess at a price because that would be commercial sales and we'd get sanctioned. But we are competitive. We have new methods of production that allow us to produce these reasonably. Plus we do all our own work in house on modern CNC equipment. We do our own engineering and programing.
My own background is in racing and engine building. My partner and I are both engineers. Pretty much gives us an edge in developing these things. Not that we couldn't use help from Pratt or Rolls or GE.
The weight of the five stage complete is under 12Lbs.
Mike, the difference in stages is between .018 and .028 per stage. Hardly something one can see in photos.
