Thank you very much. Fuel mixture is on this picture:
I try it with new exhaust. Total length of exhaust from engine will be 32
inch?
 Respectfully, Michal from Slovakia



The mixture looks OK at about 13:1.  32 inches for the front and rear end housing
exhaust ports and 16 inches for the center housing exhaust ports
as it poofs twice as often.

Here is another tuned exhaust idea.

You might also try taking out the Inconel exhaust inserts but
do this at your own risk as I have no idea what the extra
heat is going to do to the end housings and cooling
O-rings. If the cooling O-rings are stock I would
change to Teflon encapsulated silicone from Creavy O-Rings.

I am so glad you have a dyno as you confirmed  our RX8 P-port HP
numbers at 7500 RPM we recorded on the Mazdatrix dyno half a world
away :)

If all else fails switch to early p-port exhaust 13B rotor housings
with the cooling O ring slots in the rotor housing. Failing
that machine some O-ring slots in late model 3rd gen RX7
13B rotor housings using an NC mill.

BTW Michal try to make it to Aero in Friedrichshaven
on on April 8th. Leave a message with Mario in the Wankel AG
booth so we can get together and talk rotaries. You are
invited to the rotary engine beer part on Friday night
at 7 PM in hotel Wisenthal. I'll buy you a beer.
