When I removed the duct work from in front of the bulkhead I got about 1-2 mph at the end of my freeway on ramp I use for testing.
I know, not very scientific, but it works for me. I use it for both my RX-8 and my El-Camino. Problem is I have run out of speedometer on the elky, so I have to go by engine RPM which is harder for me to gauge.

The first K&N intakes had idle issues. You need to find a way to integrate a stock screen from the original setup back into the system before the MAF. This should help.

if they would of made the front of the intake filter material insted of carbon plastic it would have been so much better or even a replacement for that top, kind of what the new one is. so air from the front and the sides would rush in, and that would probably be best for this AFSC if it fit

Only the Limies get British humor. Don't try it on the Australia thread.
In fact I'd like you to delet it from mine, if you don't mind.
No offence, I love the British and some of the best times of my life were spent there. It's just a little to soon for this though.

jokes should be allowed about anything and at anytime...however tact should also be shown.
anyway deleted as requested, although i thought it was a goodun....
BTW Aussies above anyone can joke about anything and hold nothing sacred!!! Its one of their best qualities.....

Thank you and yes I know the Aussies can handle humor about most things, in fact they are great at it. Just in talking to a couple of our resident Oz folk these past couple of weeks I can tell you they are very sensitive to this one topic and grieve on a national scale.

Richard,
Back to some wing talk - what is the reason that an axial flow compressor has many small wings per rotor as opposed to fewer (and larger) wings?
And the reason why you have a relatively narrow (ring shaped) opening is because you want to make sure that the individual 'wings' deal with the same air speed (inner and outer diameter), right? Does the air speed need to be in a relatively narrow range in order for the 'wings' to work properly?
Can you recommed any books about this topic? (Just for curiosity)

Power!!
It's the same concept that most modern gas turbines use. I would look up text books on jet engine propulsion to get an understanding of the aerodynamics involved. There are some good AIAA (American Institute of Aeronautics and Aerospace) books I used back in undergrad that were helpful.
Can't wait to see your finished product Richard!!

Hi guys. FIrst of all, apologies for posting on an RX8 board. i'm actually an S2000 owner (and so fellow lover of 9,000 revs ) but accordingly I've been lurking on this thread for far too long, hoping that you RX8 boys get Richard's Axial Supercharger soon so that Richard can focus on developing it for the S2000! 
However, things have now come to a head - a British group buy for another well established S2000 supercharger is closing next Sunday and so I have to decide whether to wait for the Axial SC. Just two questions Richard (but admittedly they are difficult):
(a) How long do you envisage it taking before you will have developed and be able to sell the Axial SC for the S2000?
(b) will it be available from the date (if at all) for a RHD car?
Right, back to RX8 chat - we don't see many of them in the UK due to the price of petrol and the RX8's thirst
I like many of its design cues though (particularly the front end, reminds me of another car 
).

Some of the kits I have seen on the S2000 have me turning my head as they go by thinking I may have just seen an 8 but then realize it is the S2000. Love the car just needed extra passenger seating for functionality... 
First thing I noticed when I purchased my Axial Flow Shift Kit was he offered a S2000 shift kit also.
Remember hearing a story of how there was little faith in improving the S2000 shifter... till it was tested.

I think there is a mix of opinions on the Axial shortshifter - some owners are really happy with whilst a few owners are not happy with the extra vibrations involved which seems to come "hand in hand" with the better "feel" you get with it. I've nearly bought one myself, but hesitated due to a few mixed reports.

RP when you get done with 7-stock I need to get in contact with you
I have come up with an idea that I perceive may work to control a higher pressure version of your AFSC.
There is a patent search on going right now to see if anyone else is using something similar in a similar way. Initial very broad searches have turned up something similar in industry for larger axial flow compressors but nothing as it pertains to the automotive industry.
Advantages of a higher boost profile in the lower RMP ranges while controlling upper rpm pressures to prevent over pressurizing the engine.
Then device was hinted at over in the S2ki AFSC forum by a fellow individual that is now handling my patent searches.
It was hinted at before we decided to pursue the possible device. So he may have let the cat out of the bag to early.
