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.

 

I know this has been asked already, what is the estimated price of this unit?

The market for the S2000 may be crowded but there is still room for new ideas!

 

This sounds interesting..
Overall weight would be what?

 

following this topic.

 

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.

How does this design opperate dynamically across engine speeds and airflow changes due to the engines flow characteristics?

 

Now that you have a membership and a photo album here, you can take digital pictures of your charts (don't make them much bigger than about 700 X 400 pixels) or scan them as a photo (also scale them down to a reasonable size) and post them via your photo album here.

 

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.

 

So is this kit in developement or still in the research stage? will you be aiming for carb for people from CA? also do you have a company website? thanks.
