    Steve, No its not, although Paul has my first engine in his web site which he photographed when here a few years back. This engine has also had the rads changed back to exhaust to the outside as did not work as shown, Neil.

    I suspect he's referring to the youtube video I linked earlier. It was posted to youtube by Lamar, but I *think* that the actual machine work was done by a guy on Lamar's airport who has a mill. I've got an email from him somewhere, but can't find it right now.

    Again, working from my flaky memory, I believe that the welded tube technique was pioneered by one of the fliers on the Flyrotary list. Unfortunately, he's no longer with us (cancer).

    Rv7charlie, yes, I was referring to the video, sorry Neil for the confusion.

    Mazda Exhaust Port Air Injection Points -in J P Norbye Wankel Eng p 342.jpg
    Thanks a lot, I searched not enough about this. Could you provide figures for power, torque, SFC, emissions for this Peripheral only Intake Port, Side Exhaust Ports? I guess the old approach of air injection in exhaust port area may improve the issue of a too hot exhaust, but from days of early engines, it is known that a lower compression ratio, a lower mean effective pressure is linked, paradoxically, to a higher exhaust gas temperature, another approach for this is improving MEP. I failed in locating the Paul Lamar video. Salut + Rectangular vs Round Intake Port NSU.jpg
