if it runs for a second or two then dies....
that's just what the fc's do when the tid comes off.
look for a disconnected hose or something after the maf sensor. no check engine light?

Besides, I can't wait to see what happens when the replies reach 1000.
does the program allow for four digits?

Uh oh...its Y2K all over again...
Start stocking up on car magazines and printing out your favorite threads now; as soon as this thread hits 1000 the computer system won't know what to do! It will think it has 0 replies, and will cause Armageddon!

I have a question, which may or may not have been answered already in an alternate form.
With AF, is there enough air at the top end, like around say 9200-10krpm, to extend the onset of the gradual fuel cut-off another 1-1.5k?

I don't think I understand your question. There is enough air to keep going but what would that have to do with the fuel extending itself further. Also I don't think that the fuel cut off is gradual. If it was so then you would have a fatal lean condition. The fuel cut off is used as a rev limiter. At least that is how and why it works on other engines.
Realize that the SC is an airpump as is the engine but the limit to the axial flow is tip speed (among certain other things) so overdrive ratio has to be built to put it's redline with that of the engine. If more air is needed then a longer blade must be designed into the blower. This is not done by the end user.
Some people have claimed that for a bigger engine you just add stages. In fact more stages could do one, the other, or both add more air or add more pressure. depends on which end of the compressor you add them. Added to the front, more air and more pressure. Added to the rear, more compression.

Most exciting thing for rx8 for me atleast
I've been reading this forum for about 2 years now, even before I pre-ordered my RX8. I would like to say Richard is doing something that makes me want to finally post! This is the most exciting thing for the RX8 =) Axial Flow Supercharger. I've been reading this thread since it first started and everyone seemed to knowledgeable. Reading this thread, you can always learn something.
Thanks Guys.
Thanks Guys.

I hope I have an RP AFSC installed before this thread hits 2000 posts -- scratch that 1500 posts -- scratch that 1250 posts.
Back to work -- no more jet engine chit chat until we have a prototype installed and getting tuned. :p
My 8 is sitting under cover in the garage (15 inches of snow on the ground) -- I should have shipped to RP for testing

Yeah -- that's me -- I check in every day. No kit on order yet -- I have been patiently waiting for RP's AFSC -- though I must admit it is getting tough with SSR/SFR turbo coming soon. I am going to try to check on that one next week when I am down in AZ. As a former Aero Eng. student (CU-Boulder) I have always has an affinity for RP's solution. I also think an SC will be a better fit for my driving needs. I want to have a kit installed by the time it warms up here in the frozen tundra. I have been ready to write a check for a long time -- just nobody has been ready to send anything for it yet
Oh well -- I have been entertaining myself by collecting a few Panerai watches :o
My 8 seems happy all snuggled under the covers watching it snow outside. If she wasn't all detailed out I would take her out for some fun since I do have winter rims/tires on her.
Come on RP -- get busy :D
