If you're into smithing, this may be the engine for you!
Since Bruno proved that the Fo Mi Chin II engine runs "sweetly", we can now use that intake design with the FWE chamber to create the 'Sveldt Lady', an FWE that will fit anywhere a Dynajet can go - overall length is 21.5 inches, front view profile is a 2.6 inch OD circle! The tricky weld underneath the intake is gone, but this time you have to make the cone out of a big "horseshoe" shape, as shown below.
The intake is made from a half-shell cut from a pre-flared piece of 1.25-inch tubing, exactly as in the FMC II but pinched a hair narrower to expand the center height a little for better intake cross-sectional area. Starting air / fuel tube is my standard design, fabricated from 1/4-inch OD brake line and 1/8-inch OD copper tubing. For intake fabrication details, see the photos in my Fo Mi Chin Re-work thread in this forum. See:
I WILL be making one of these, from the second chamber cone Steve made for me; however, anyone who's itching to try a new design can blast away at it and beat me to it, if you want to be the pioneer builder [guinea pig, lab rat, etc.]. Go for it!
Why am I calling this one Version III? Well, as I see it my original planform and anything basically scaled from it is version I, and the 'straight FWE' designs developed by Steve and Eric should be Version II, leaving this one as Version III. The way I see it, scaling and minor variations in intake dimensions, etc. are merely 'variations', whereas 'version' implies a significantly different profile to some part of the engine.
