Hi, Paul....sorry for the delay in getting back to you....a lot of "stuff" has happened. Please hold off for just a little bit on designing a new manifold for me....I appreciate the efforts, but
don't want you to waste any of your time.  After talking to Leon in Australia, I picked up a NA 6 port 13b engine. He said I can get more "ponies" with the higher compression rotors, and porting.  I
just finished pressure washing the new engine. It was running when taken out of the car last month.  Now I have to decide wether to go with mild street porting as Leon suggested, or go with PPorts.
Of course this decision would greatly effect manifold choice and design.  Thanks for your efforts of late....just don't want you to spend too much time designing a manifold that may not apply.
      I talked to the manufacturer of my 64 x 78 prop, and he said it was designed for a builder who had an E-Racer with a planned turbo 13b over 200 horsepower.  Wishing everyone a Happy New Year

Leon and I had a long discussion on here a few years ago. He convinced me he had all
these rotary resources in Sydney do do all these fantastic things and a great shop to do them in.
I flew to Sydney specifically to check it out. I met Leon near the airport and spent the day driving
all over Sydney. None of it was true. Just a bunch regular rotary community suppliers some of 
whom had not seen Leon in years. No shop... no nothing! As I understand it he is in and 
out of the hospital on a regular basis. If I never hear the man's name again I will be very
happy.

Your manifold design is almost done anyway. I need the dimension from top
of firewall to top of spar and the depth of the spar.

The six port needs extensive modifications but once done it seems to be the
hot tip in road racing these days. From reading the above I assume you have the
four port engine with low compression rotors. Where did you get that?
could be part of your HP problem.

Your prop can be shaved a bit to fit 190 to 210 HP which with a good six port manifold 
and ram cold air is right in the ball park.
