Improvements to the Rotary?

[dr.occa]

Saw this video on autoline.tv:

Episode 997 – New Subcompact for Brazil, Auto Sales on the Rise, First Zinc-Air Battery? – Autoline Daily

Here are some images of a modified and factory housing side by side captured from the video.

I contacted Mazdatrix about performing this modification to the housings and here is the email conversation:

Sorry, no. We have no way of doing that. Also, getting the filled-in area perfectly flat with the rest of that area of the rotor housing would be extremely hard to do.

I would like to test this modification’s potential on a 12A motor of mine. Would Mazdatrix be able to change the rotor facing side of my spark plug ports to slits no taller than 1.5mm slots? If so, could you provide me with a ballpark estimate of the cost for this modification to be performed on 12(a) housings? I’ve attached t(w)o images to illustrate what it is I’m wanting. Thank you in advance.


I was disappointed to here their answer.

The way Ernie Brink described it, it makes sense that it would greatly minimize if not almost eliminate compression & mixture loss as well as reduce exhaust temps. Reduced exhaust temps would also translate to a cooler motor.
