Okay...so I was watching the vid posted here
https://www.rx7club.com/2nd-generation-specific-1986-1992-17/epic-quest-hit-200-mph-bonneville-810225/

And I decided to check out the website at the end of the vid.

And it pops up with this



WTF!!! 16B???? ALL ALUMINUM??? WTF???


What the heck is this??? So I did a little digging...and...
http://www.rotaryeng.net/VTOL.html

Here is magical quotes like...
"The all aluminum Mazda 16B engine introduced in October of 2007 weighs about 185 pounds and is capable of about 285 HP at 7500 RPM."

"MAZDA 16B PERIPHERAL PORT ENGINE

The stock Mazda 16B is not a P-port engine. It is a side port engine. However it is fast and low cost to modify it as a p-port engine by boring holes in the rotor housing and welding in tubing. This improves the volumetric efficiency across the RPM range of interest by 20% and so too the HP. The engine is capable of a BSFC of 0.47 which is in the range of most light aircraft engines. Perhaps 5% worse than the best. In turbo compound form it is theoretically capable of a BSFC of 0.4 or below. It is also capable of running in the range of 18:1 to 20:1 air fuel ratio at high RPM and low load. Our theory on why this is possible is due to the fact the engine is a rotating combustion chamber engine. This forces the heavier fuel molecules out near the spark plugs. In effect it is naturally stratified charge. The red line on the stock 16B engine is 8500 RPM and a P-port 16B engine will be making close to 300 HP or more at 8500 RPM. Consequently it is a better high RPM high HP aircraft engine than a low RPM low HP car engine. It's exceptional power to weight ratio more than compensates for the slightly higher fuel burn of a piston engine. "


So what now??

Some of what he says appears to be a bit off. The first quote I have says its capable of 285 but doesn't say any mods...so stock it may be 285. But on the graph he shows it closer to 220 as if it were a renesis maybe. And he says a P-ported 16X would be close to 300hp...though this seems like too small of a jump from 285, or even 220.

Anyway...figured I would put up what I found...

Anybody know Paul Lamar?

Apparently Paul Lamar wrote 'How to cool your Wankel'

The lower numbers are more than likely figuring in drivetrain loss.

I'm interested, though, how he would figure anything else out about the engine considering that it hasn't been released yet, at least I don't think......

And also, Mazda had the announcement on their website at one point in time that gave all the specs about the engine itself. How much lighter it is than the Renesis, etc. etc. etc.

Seen him in person, read his work....... wouldn't trust any of it, just because he is in aviation he comes off that he does not need to listen to anything anyone from the auto industry side. The scariest part to me is there are people out there that listen to him and build airplanes using his theories.... I hope they don't live near me.
