I can for sure feel the added power as I let build boost. It is nice under freeway cruise to add throttle and feel the extra torque.
It has synthetic oil in it now.
The outlet 90 has 5 layers of poliester weave.
We could have a oil res built in but this takes away the heat better.
Roots (ki) did your ancestors (Roots Bros) desighn the original PD blower?
Alt will be self compensating. It is better then a turbo in that the temp doesnt effect the boost. In a turbo it has to work harder with less heat and density so may get into an inefficiant area of operation.

You cannot hear it unless you open the throttle and then it is only a slight whine. If you know its there and listen for it you can hear it standing next to it. I drove it down between two block buildings just to check and it is there but hardly. Only if you know what to listen for, otherwise you might think it was an alt going out.
So, in other words, it sounds just like a stock RX-8...being chased by a 737. 
You need to spend less time hanging out with Tom Cruise at the mall and more time memorizing this thread.

The very high harmonic frequencies the AFSC was putting out probably scared him/hurt his ears so he ran away.
Or he was just scared of what real power sounds like coming out of a AFSC and not the roots, twin screw...ect

Wow- I dont' check this thread for 2-3 weeks and I come back and there seems to be major progress!!! This is outstanding. I have been silently following this thread from the beginning, and frankly was doubting it would ever come to fruition (though it clearly seemed from the start to be the best design out for FI for a rotary)
I have taken rides in Cam and Candy's supercharged 8, and a Greddy tubo'd - so I have had a decent demonstartion for what FI can do for this car. (I liked the Pettit batter than the Greddy, even though it did seem to top out in power early- I just thought the supercharged version "felt" more like the character of the 8 than the Turbo'd did.
As Richard mentioned he thinks the progress is going to ramp up based on actually having a working unit in a car. I can't wait - Richard is the true "American Inventor" - though somehow I don't think the ABC show would have gotten the significance of how this supercharger is better than other designs.
Richard- Maybe you can have a weekly or Bimonthly update posted in the title that people can look for to qucikly get up to date with the progress you are making.

Richard, (I believe I have this right) But since you are making your own oil filter sandwich plate for the pressure/temp sensor and the oil feed line, have you considered modifiying the end of it to accept a larger oil filter? Bigger is better, no?

There is no room in there now. The size of the filter is fine, just change it on time.

Erk...ok I was just pm'ing people about buying some new wheels...but I think I'll leave the money in savings now! This is very exciting, way to go RP!
I don't read for a few weeks, and all of a sudden the AF supercharger is mounted, and there is a new engine management guru that has solved all of our EMS voodoo problems! Exciting times, exciting times.

RP The older 13Bs had an area in the foward housing that you could drill and tap for an oil return. I would think this engine would have the same thing. It was there on the older engines for the posibility of mazda adding a turbo. I would think this would be better than tapping into the oil pan.

That would be nice but getting the housing on the mill requires taking the engine apart. I don't think that the avarage buyer is wanting to go through that.
Drilling and taping in place would put chips in the engine.
We are going to be building an engine from scratch with porting so we will look into it on that engine.

RP,
It is simply GREAT that you finally have a running vehicle with the AFSC installed.
I have learned a LOT from this thread, and look very much forward to hearing how the FM stuff is sorted out.
Thanks to RP, RG, Hymee and Swoop for all the tech!
