And there are those who strive for more and more power but In aviation, I believe, it is reliability every pilots main concern. Thus redundancy is mandatory in every mechanism I would find it extremely interesting if you could do a video on Viking Aircraft Engines Here again is a company using automobile engines in aviation But with a different approach That of reliability Power can be achieved but their approach is one step at a time with reliability as first and foremost priority.

You can depending on the manufacturer. Yamaha is known to have different valve spring ratings between the two. So you would have to re-work the head. Then rebalance the crank. To do all that DOES NOT cost that much.

@craigsanders6925 4 года назад

That includes the gearbox and prop as well. You're talking about a motor that weighs just over 100 lbs, and rebuilt can easily make more power. My 2008 R1, it's a similar motor, made almost 180 with a full exhaust system and dyno tuning on a stock motor. Match the ECU map for the use, dial in the cams for where you want them and tune it for best power application. Non turbo super bike builds are making well over 200Hp.

Интересно блок двигателя дюраль, как он противостоит нештатным нагрузкам?

@keithfreeman5204 4 года назад

With that kind of RPMs what comes to mind is a system based on a Multi Fan Blade Ducted Fan. A Cold Ducted Fan with Direct Drive. In a Duct, the wing tip vortex's from the prop tip, are eliminated thus gaining efficiency , about 20 %. In my Mind's Eye, I see the engine and impeller enclosed in a Venturi Shaped Duct. An air cooled 2 cyc engine behind the impeller in the slipstream would handle the engine cooling. Side note..... I've been building and flying Model airplanes since 1959. Got my 1st Radio in 1976, been designing, building and flying R/C ever since. Build in the winter and fly in the Summer. I get an idea, draw a sketch, cut, glue, assemble, fly, break, rebuild, fly. This Yamaha Engine in a Ducted Fan with the High RPMs should be Mega Thrust. From Ionia KEITH

@tinolino58 9 месяцев назад

If your ducted fan gains 20% efficiency than you are above 100%🤩

@specforged5651 4 года назад

Shouldn’t even be a second thought between carbs or fuel injection. I mean absolutely ZERO thought really. Also, you shouldn’t even really have to develop and R&D a turbo system for the Apex, the snowmobile guys have been doing it for years and years. I completely understand a few tweaks and bugs here and there, like exhaust manifold/collector, charge pipe/induction manifold routing and intercooler maybe if your using one. However, the fuel mapping, computer, proper turbo, etc.....there are many many guys who have that down perfectly. Certainly shouldn’t be necessary to start from scratch just because it is going in an aircraft right?

@vumba1331 4 года назад

The mapping for an aircraft is completely different from a car. I've done it and the maps that were provided with the ECU were completely inappropriate and I had to start from scratch. Been flying with my setup since 2009.

@WishingForSerenity 4 года назад

Something used on a snowmobile doesn't necessarily fit or work on an airplane. As he explains in the video, he had to come up with his own exhaust system because it can't be fitted the same. And with different gearboxes and ways the power is used at a higher band of altitude changes comes the need for different mapping and adjustments.

@DS-bl3cr 4 года назад

I am wondering what makes the Yamaha engine competitive compared to a Viking 195 or an aeromomentum engine. Is it the weight? Doesn't seem to be the price.

@dragon2knight 4 года назад

Not a bad engine...but I also don't see too much R&D on these either. I'm not too sure I'd spend that kind of cash on something so unproven. Aeromomentum is doing a far better job on the R&D front (easily the best of all the auto converters out there IMHO) with significantly lower prices. I'd approach this one with caution till a few hundred hours at least are on a few of these. If it works out okay after that, fine. If not....

@machinesandthings7121 4 года назад

I haven't seen the weight for the turbo setup, but it has to be alot lighter than the honda auto conversion. These engines also have a lot of history and testing of turbo setups in the sleed world. They have proven to be super reliable in that application. That doesn't mean I disagree with you about hours of testing on this specific turbo/fuel injection setup. The fact that you are not getting a factory built engine also adds variability that I don't like. And the price... 40k ouch

@craigsanders6925 4 года назад

About 115-120 lbs, that was his price that included gearbox and prop which I'd guess costs about 6K.

About RPM - - - I had a Honda CX 500 motorcycle in 1969 that red lined at 10,000 Rpm and everybody said it was a time bomb because of such high RPM. It was the most reliable Bike ever. I could take it up to 10,000 RPMs every shift and I often drive in a lower gear to maintain the 10,000 RPMs and it was only a 2 cylinder so RPMS mean nothing if the motor was designed to be a high revving and built by a good company Like Yamaha or Honda.

If you go to his website and check out the price page he is offering the Rotax and Yamaha. The 150HP EFI Apex is (w/firewall forward prop and hub) $23k the 100HP Rotax 912 is $28k (FF inc) the 914 is $40k (FF inc) The Yamaha 300 HP is $43K. There is a rather large difference between the HP and whats included for $43K. In neither case are you buying just the engine. For 300HP ready to mount isn't that ridiculous. Yamaha makes a great engine if they provide the correct modifications seems like a fair price.

I always thought the point of using alternative engines was to lower the cost. Yes, it's a cool engine but damned pricy. And you're basically getting a secondhand engine.

exactly what I was thinking. If im handy enough to build an airplane from a kit then ill find a 2nd hand engine rip it and and install myself. Of course ill buy what i need like the fearbox but holy crap iv seen these engines going for 2-3K.

but let me add that if you have the money to throw around, if your looking at a highlander Id sure throw it Steve Henrys way.

@Ryan You can buy a used APEX sled for $2000 or less all day long. I know because I have one. Lovely engine, its true. Its as smooth and happy as can be to squeeze 11K rpm all day long and lots of guys have huge miles on the sleds with no engine issues. Maybe I can sell my sled for more money now lol

@Ryan You don't need 20k to turbo.an R1 engine (what an Apex essentially is). Maybe 5k.

yeah, but what's the TBO. Sure i ride high performance sportbikes, sometimes at high rpm for the thrill. But i don't think it would make any reasonable TBO doing that long term. 20K+ for one of these whizbangs? When it quits on a sled no one thinks about it---it's when your with your kid drivin' over the mountain that you think about it. Nice vid though.
