New engine technology - lots of HP out of a small package

[Gimpy1]

Durability has always been the tallest hurdle. I remember when euros were making 1,000 hp out of a 4-cylinder race engine back in the late 1970's/early 1980's.

Yea I think nelson piquet's F1 Brabham BTR53 with the BMW M12/M13 2.0L turbo car made 1200 to 1400 HP but it was a beast to drive, needed an exotic fuel mix, and only had to last 1 race. It wasnt really practical nor reliable. I believe BMW had a qualifing tune which made more power at the cost of engine failure and was used only for qualifing.

In the advent of a lot of European auto manufacturers moving to the EV industry here comes another technology. Oh my, I'll just stick to ICE.

I think "close" tolerances will not be a solution to not using Apec seals. Without Apec seals I'm sure it will run for hours in a laboratory but, not practical from an engineering perspective in real world use. I am sure the Mazda rotary engineers faced this decision long ago. JMO Ed

Why no dyno charts?
Whats the torque curve look like?
Whats it make at the RPM you can build an affordable trans and drivetrain for say pull it back to 9K ?
Why No teardown after hours or runs to see what surfaces wear?
How cleanly does it burn?
Whats Brake specific in 500 RPM increments under load?
Whats its expected lifespan at half or full load?


Did Mike Rowe show up to check it out, or how about Howie Long?

Ive sen all kinds of cool stuff that never went anywhere, but Im always hopeful a better mousetrap will come about.

If it revs to 25K and only makes 160 HP max, then I'd venture to say the max torque isn't going to be much over 35-40 ft-lbs. Going to need some gearing to get any useful torque to the wheels.

On their website they show a " 2 pack" that doubles output, but yeah.....that first step down from 25K is going to be a beefy part...

Its a great electric charger for sure - you can make crazy high voltages from that RPM and run that thing at any output to perfectly match load at a given speed vs always being over or under.

Ultra-high revs, like 25K with this design, are not desirable in a vehicle engine because of the need to gear down. This is one of many reasons gas turbines never caught on in cars in the 1960s.

Surprisingly, light aircraft running ICEs have the same issue. The prop can only go so fast. An engine able to run 25K rpm is of little added benefit.

That and some sort of CVT on a motorcycle? Would like to hear it running. Maybe.

Way back my best friend added a wankal engine to a motor cycle
