While it's generally true that putting a higher octane than your car is designed for in the engine won't improve it's performance, modern engines are smart enough to detect that there's better fuel available and will adjust their fuel mixtures and if relevant boost targets to make use of it.

[@larsjrgensen5975]

Only to a point where the engine would still be knocking with low quality fuel to begin with. My car engine only scales to 98 RON Europe rating, it is overfueling if cooling is needed, so 100 RON will use a little less fuel when flooring it, but no extra power will be generated. To take advantage of very high oktane aviation/racing fuel more compression ratio, more boost/air flow and more durable parts are needed, the result is a higher engine cost. The higher engine cost is the reason modern cars only scale to a point where it makes sense, because most people are not fueling aviation fuel.

[@hhhhhhhhh1071]

@@larsjrgensen5975so instead of using the same amount of fuel per cycle to produce more power (due to higher octane number), it uses less fuel per cycle making the same power for less fuel? I guess that would work better for an everyday car, since you’re mostly just using it for getting around at lower speeds anyway

[@larsjrgensen5975]

@@hhhhhhhhh1071 I am not sure if we are on the same page. This is an example for understanding, real life is more complicated. my car makes around 220hp If throttle is blocked to produce a max of 190hp, low or high octane makes no difference because the engine does not knock. If throttle is blocked to produce a max of 200hp, the low octane fuel needs extra fuel to cool, but the power is the same and the driver will feel no difference. If throttle is unblocked to produce a max of 220hp, the low octane is limited to 200hp no matter the fuel amount and compensation, but the high octane is able to safely let the engine make 220hp. If the engine is upgraded to handle 300hp the normal pumpgas high octane might not be enough and E85 or aviation fuel would begin to make sense. Fully agree on the everyday driving, 90% of the time super high oktane is not really needed. If going on a highway roadtrip premium might be the same price in the end, because the lower octane maybe needs 1-2% more fuel to cool, but it depends on the car, outside temperature and driving speed.

[@hhhhhhhhh1071]

@@larsjrgensen5975that makes more sense, pretty much all my simple-in-theory real life projects turned out to be a much more complicated mess of factors

[@SmallAndDisfigured]

​@@hhhhhhhhh1071 The guy you’re responding to doesn’t know what he’s talking about. A higher octane does not mean that your car will “use a little less fuel when flooring it”. The point of a higher octane is that it resists ‘knock’ or ‘pre-detonation’ which is where the fuel begins to combust prior to the cylinder arriving at top dead centre and as such the camshaft is ‘cheated’ and the cylinder stressed. A higher octane can allow the engine to achieve a greater amount of compression which results in a greater amount of energy being drawn out of the fuel. Putting a higher octane value than your car is rated for will do absolutely nothing for your fuel economy or power-a higher octane does not add any energy to the fuel, it only allows the fuel to be manipulated within the cylinder to arrive at a more efficient combustion.

[@captain_commenter8796]

This game is a lot deeper than I thought it would be. Most simulators I’ve played don’t come CLOSE to this amount of detail, absolutely amazing!

[@alexturnbackthearmy1907]

Its one of the best simulations out there. You can do all sorts of silly things (like that one jet-powered prop driven german VTOL thing), and they will be simulated pretty accurate.

[@Mr.Scootini]

Interns of aircraft “RnD” I can’t agree more however I think XPlanes Plane Maker beats this by a mile. That being said it’s a far more difficult game to start making planes in. If you’re speaking flying games as a whole, may I suggest you DCS and MFS

[@clumsygarage1578]

6:25 *a lot of modern cars, especially turbocharged ones, will change ignition timing and turbo boost when they detect that they're running higher octane fuel than their minimum, so they will make more power.

[@Leonard-nb7jk]

[@REAL-BIG-HAM]

If you are wondering how to figure out your prop speed. You want it to be between 0.7 and 0.8 tip Mach “that is shown in the propeller menu”. And in order to get that speed reliably, you take your engines rpm at max power for whatever altitude you want to optimize for and divide it by your prop rpm to get your gear ratio.

[@Knot_Sean]

Now I want to make an extremely unnecessarily large and super efficient supercharged diesel engine in flyout meant to drive a counter prop for a 1945+ bomber design I got on paper so far.

[@deltacx1059]

Would be cool if automation had a flyout plugin for exporting engines, it has a very good engine editor also focused on realism.

[@kelevra558]

Lift and duration of the camshafts and the way the cylinder head flows play a much, much bigger part than bore, stroke, and fuel. Lobe separation angle plays a part as well. Unless you have forced induction in which case you definitely need to look at the flow rate of your cylinder head and definitely want to run much stiffer valve springs to avoid floating them.

[@jakubpollak2067]

I like your enthusiasm, but you know that there are no such settings, right? This is not automation game (yet, I hope, cause that amount of details would be cool)

[@someweeb3650]

Nah you actually gotta reduce valve size on turbo engines coz the head flow is so dang good in flyout your engine destruction point will almost always be before peak power with any amount of boost

[@jakubpollak2067]

@@someweeb3650 Oh, ok that setting is there. :D I never actually used a turbo or compressor, I'm happy if I manage to lift my abomination from ground :D

[@safeish57]

piston engine? why'd you do that on the engine...

[@irritatorgoner1087]

So... Forget about my previous requests, i have something new to request to you. I have seen a while ago a video about the xf5u flying flapjack and i can't just stop thinking how would his performance be like if had been a success. Can u possibly fixed or improve this aircraft?

[@saltyradiation706]

Is this the begining of messier-weekly??

[@todeilfungo]

I waited for this video a lot

[@jrojassengard2586]

I wonder how hard it' be to adapt a car engine for airplane use. Probably worth looking into techniques used at the Pikes Peak hillclimb race, where race cars reach some pretty high altitudes

[@red1246]

Well there's that, but an other big problem is the fact that a car engine always operates in the same angle while an airplane engine can turn in all positions, thus you have to quite heavily modify the lubrication system from a wet sump to some kind of special dry sump

[@CormacLavelle-op5ux]

My gramps worked for pays an Aussie warbird restorer working on these sorts of engines he probably would’ve loved this video when he was still around

[@RandomGuy-hr8sb]

How did you learn so much about aviation?

[@rowbot5555]

Its something called autism :3

[@Tacticaviator7]

Hey did you consider some minimum power ultra light build challenge ? The lowest I could go was about 15 hp with 250 kg weight, was pretty proud of that one but I wanna see better.

[@roaling2]

Nice little tutorial!

[@TheStupidRuski]

Im playing flyout rn

[@Madkite]

Can you do an opposed 2 stroke diesel. In theory you can boost until it explodes as it doesn't suffer from preignition. They were around in the 30's but development didn't rub its course.

[@ladzhandle]

Would love to see something like this for tubine engines

[@theshinywaffle]

Now I have to watch this while biking 😔

[@ChristopherGriffin-ee2ol]

I get it that you mentioned Radial, Inline, and V Engines, but didn't mention W Engines, W engines are Engines are engines that are basically 2 engines in 1, if it's a V engine and an Inline engine in one, or two V engines in one, tak for example the MK-44 Engine, which is 2 22 cylinder V engines in one, have 7,546-8,000 horsepower tops, though expensive, has quite the bang for buck

[@jakubpollak2067]

Do you even play this game? There is only inline, V and radial settings in game, so if you want boxer W or something else you need to make it out of inlines hard-coupled together by gearbox

[@ChristopherGriffin-ee2ol]

​@jakubpollak2067 No, I don't, and yes, there IS only 3 types of engines in Flyout, but those engines I mentioned 4 types of engines, sadly what I didn't mention R, and Nuclear Powered Gas Turbine Engines, R engines are basically 4 in one, mostly 4 V engines in one, it is VERY popular, sadly it is experimental, and Nuclear Powered Gas Turbine Engines are concepts, basically the 5 other engine types if they require Nuclear Energy to run, if done right, these engines can run FOREVER, but their just like THAT, concepts, only in the Fallout Series

[@jakubpollak2067]

@@ChristopherGriffin-ee2ol Still I don't understand why he should name different types of engines, that are irrelevant to this topic, neither why you do you keep naming more. Nuclear engines don't run FOREVER, they are not just concepts from fallout series, they exist and work, but they are too heavy (shielding) and risky to be used in airplanes. Go touch grass or do some more research about this topic.

My main problem is that any engines with similar parameters to real world planes seem severely underpowered in flyout. I'm guessing it's just my poor propeller blade tweaking, but I can barely get a 1200kW engine past 300kts near sea level when similarly powerful planes had a cruising speed well above that😢

[@Tacticaviator7]

300 knots is huge for 1200 kW what do you mean ?

[@AE_Sub]

@@Tacticaviator7 the LF Mk IXe had 1283kW with a max speed of 350kts at 21,000ft. The craft I made can barely get 305kt on the deck and struggles to get close to 250kt above 15,000ft.

[@Tacticaviator7]

@@AE_Sub Hmm, you getting good manifold pressure at that alt ? Usually forced induction planes have better speed at higher alts.

[@Ausogiea]

@@AE_Sub why are you comparing on-the-deck speed with 21,000ft speed? There's way less drag at 21,000 feet. Of course you're going slower at sea level.

It is not really possible in flyout in a capacity that properly works. At best it can be modeled with joints, but there is no way to physically connect it to an engine with real throttle response
