That's what I was thinking, first one I drove was a 1970's NSU RO80 had some unusual shifter IIRC touch shifter knob to disengage clutch? Hard to drive

Anyhow, the 12 rotor is an awesome project :drink:

Attempting to counter bad publicity over Wankel reliability, NSU installed two Ro80 engines in this power boat.

so you had a shiftable crash box back in the 70's..

I talked to a guy that raced in the 1970's with wankle outboards. He said not only did he win every race that he entered but that he lapped second place unless there was another rotary in the race.

True. Most will spend their time in the 4000-5000rpm range. But depending the hp/tq ratings in the rpm curve with the rotor vs big block, they may have to turn higher rpm. But this is just thoughts on how my turbo 13b runs in a sandcar. The 12 rotor is completely different from that! Haha

[ATTACH=CONFIG]520433[/ATTACH]Sorry, I misled you. There was an engine and a car with the same name, the car was as ground breaking as the engine.

I just found the boat as I was checking my memory of the car and thought I'd throw it in.

that's only 30k can ya shoot for a buck lol - - - good luck with the new power plant, I know you have a lot into it!

Incredible engineering, that thing is awesome! But what's with the carburetor??

it's a prototype, think carb was simple for now, assume it will end up with a turbo, intercooler, throttle body inj. or direct fuel injection into the combustion chambers. turbo will help immensely with a rotary engines inherent low compression, we will C

yep, carb was a quick way to make sure the engine design worked, the carb does not care what kind of engine it is on it only knows to put the right amount of fuel into the air for combustion. This engine is 960 cuin so the carb would only flow enough air to take the engine to 3000 rpm under full load. We did take the engine to 8000 rpm with part throttle loads. The EFI computers and throttle bodies showed up a few days ago. So I should have it back on the dyno in a few weeks with the efi, as long as that goes good I will put the turbos on it.

Very cool project. Whats the Life of these motors? Has to be better then a bbc or abc.

I obviously can't speak about this design, but the rotaries in general are known to be very reliable, although the apex seals tend to be problematic. Unfortunately, to change the apex seals typically means tearing most of the engine down to replace them.... so this would be my question, how difficult is it to swap the apex seals on this design?
