BTW stop by SZP on your way home as I will not be at
Copper State. I will be at Seven Stock. I think you would
learn more if you came to Seven Stock on Saturday instead.
You could talk to the guys running P-ports and 4 rotor turbo's
on their  street cars :)

Paul,

When and where is Seven Stock being held?  I would love to attend
myself.

Where: Mazda North America Corporate HQ Center --
Irvine, California

Did you know: this years SevenStock is at a new location?
On Saturday morning, don't go to Mazda R&D on Reynolds!
Go to Mazda Corporate HQ at 7755 Irvine Center Dr, Irvine Ca
Tell your friends too... don't let them end up at the wrong
location!

Too bad it is too far away. I would like to go. Please provide a
report Paul.

We usually do. Particularly if there are some interesting
parts for sale.

Here are some old 2003 pictures of an all aluminum four
rotor Scott somebody made. I think Linden Blue, CEO of General
Atomics Aircraft Division owns this engine. Jerry Hey is
in the back ground taking a picture :)

The last chart is very very interesting indeed. This shows
the rotary engine will run at air fuel ratios as high as
25:1. 21:1 seems optimum for best BSFC. Tracy Crook
confirmed this finding. No gasoline piston engine comes
close to running at these high  air fuel ratios.
This is diesel territory. There is that natural
stratified charge effect again. Notice the BSFC
steadily drops and is at a minimum at 330 HP
(82.5 HP per rotor) and 5000 RPM in the HP chart.
After that increased engine friction starts to dominate
BSFC IMHO.

Also Scott did a bit better on the BSFC at .44 than Mazda
did .47 with the Lemans engine but that could be instrumentation
error and or running it super lean.
