If your referring to the rb innovations supercharger, they simply dont work. Well I guess that's a misnomer, they work at WOT at peak rpm, but not well, and fuel consumption is through the roof. Most of the extra fuel air mix is lost from poor timing numbers, not designed for a forced induction engine, as with most 2 strokes to get full benefits of forced induction some sort if exhaust valving should be implemented, and or direct injection technology to mitigate fuel leaving the cylinder with the bypassed air. Ski doo has just released an engine that is turbocharged, but I dont know how one would make the tech used small enough, and light enough for saw use.True the Math & theories around this stuff has been around a long time. I would say his solutions are unique to maximize the implementation of those numbers, therefore innovative. I'm sure there others but I would be interested for you to show me another more innovative than his motor or even a channel that has taken the math and put it into practice at the level he has out side the well funded factory operations as Yamaha was and KTM, Husqvarna, and Stihl. That is what "pushing the boundaries" means And he shares with humility. There is this guy who's putting forced induction ideas on rc motors.... After spending my first career in "bleeding" edge technology, was always interested in the personal dynamics of the true innovators. The "ridged" this is the way it is types rarely innovated anything always going back to the established for security. Often that "front" is as much about convincing themselves of their theory & knowledge base as anything. The more secure and not concerned about the reaction from others types usually were "free" to explore concepts or push boundaries considered. This dude is entertaining as he has that spirit. We have a few here as well. Four come to mind that frequent here, two are "established" builders... ( and in my most humble opinion one is a true innovator, although he might not see it that way, my opinion )
And I think it's cool to GET the discussion going relative to things like reed and rotary valves, thanks to the OP. Internal combustion engines did go through huge changes during the 1930-1950. The history of the "Miller" race engines and some of the early two strokes is really interesting. Loved learning about the "sleeve valve" aircraft engine. By the 1970's the issue changed from how to get power to how to get rid of heat on the dirt bikes so MORE of that power could be had reliably. And to me that is the 800lb gorilla in the "saw" world because of space and weight constraints. Why the new designs from Husqvarna and Stihl are..... innovative in using that heat in a useful way. Kind of hard to blend the Yamaha road racing 125 cylinder , water cooling, and pipe to a saw that has to be carried around. Maybe some of the more knowledgeable folks might want to go into why those transfers are routed as they are on the new saws.
( My opinion on reed valves is they are a great way to build a motor with a larger range of useful RPM's with good peak power vs. being all about "peak" power. Outboards come to mind as they are essentially "one gear" machines, so have to both get out of the "hole" to pit a boat on plane, but then have the power to get to higher RPM's for speed. Don't know of many piston port outboards when two strokes were the rule vs. four strokes, had reed valves in the 1940's and 1950's on outboards. )
Another point, although I find his process fascinating, he is working around his own paycheck and unregulated by any governmental entity. These are important factors in the implementation, and advancement of any engine.
The secondary issue as I see it, using the loop scavenging method, weather piston ported or reed valve, you still only get a narrow window of peak efficiency in a 2 stroke. This has always been a constant, even with reed valves it's not much better over piston port or rotary port engines. This can be seen in many examples from small nitro rc engines, to larger reed case engine. So really we should be looking to achieve a few different things, a wider useful power range, and higher efficiency at a wider rpm range.
