It
is ingenious, but it's also a dead-end in the sense that, as you point out, it will never be of use outside of racing or some specialized application. The system is too complicated, and there's just no practical advantage to screaming around in your mini-van at 20k rpm. Fun, perhaps.
Sure, if you're not looking for road-relevance or concerned about rev limits, then I'm all for it. Bring on electromagnetic valves, too.
But even leaving road relevance aside, if you wanted to reduce revs, wouldn't it make sense to just eliminate the one bit of kit that created the problem in the first place? The problem, of course, is that these engines have been around long enough to have become a part of the sport, so there's a bit of a reluctance to change it, which I understand.
The art of regulation I think is a lot like bonzai. No,
really. If you're doing bonzai, you can't just take a plant and tell it what you want it to do. You can't tell it to grow a leaf here, and a limb there, and to get it all done by next week. It's a partnership, where you guide it's development by encouraging growth in some places, and nipping off growth in others. It's organic and iterative and requires patience and a focus on long term results.
So, think of pneumatic valves as a limb that looked cool at first, but then began to get in the way of other things. The rev-limit solution is akin to just constantly nipping off the end of the limb. It gets the job done, but you're left with a stubby twig that just keeps getting fatter and uglier and more useless. Better to just saw it off at the base, imo, even if it leaves an unsightly gap for a while. Eventually it will get filled in.
And yes, feel free to call me BuddhaPup.
