Supercharged chainsaws should be a thing

[@General_Madness]

Yes! Someone NEEDS to do this! Maybe even a turbo leaf blower, where the leaf blower spins the turbine?

[@A_river_dirt_cheese]

I will make one in high school

[@hithereperson8137]

Not if they sound like THAT

[@charlieandersson4069]

should be easy to make the highest mpg car now

[@Loloskye1]

Dude to actually hear your engines press the PULL button

[@General_Madness]

One problem I’ve noticed is that when you do the sound test, you up the throttle without upping the rpm target. The engine won’t actually rev up unless you increase the rpm target to wherever you want it to rev to, or just click the PULL button

[@nsmkke]

Real

He did the same thing last time and it drove me up the wall a little lol

[@DaniBatkataBG]

Supercharged small engines should not be a thing qmd they aren't in the mass production world. Supercharging is not just a task for you, but the engine too. Small engines benefit more from almost "free" power from turbos than the large friction devices called superchargers. Don't get me wrong, I like superchargers but not on tiny engines

[@_jan_79]

thanks, this made me reallly mad XD

[@sdsolympusmonsswsc-1152]

"let's do a pull" **doesn't click the obvious pull button**

[@talcbba]

also increases throttle but doesn't increase desired rpm

[@ghoulbuster1]

I think this guy might have brain damage.

[@ram_stick_samurai]

sounds fast, goes slow. now put a tiny v16 in it.

[@849hungarica]

good idea

[@mot3600official]

When I had a working computer I put a 1.5L v8 in a kei car. Now I wanna put a 1/6th scale V10 engine in a kei car

[@ThaPietjah]

When you want to test the engine you need to raise the RPM Target. Otherwise it will stay low on a pull. Or you can set the Throttle on 100% and play with the RPM slider.

[@MrLilredmachine]

400hp per litre. Certainly the highest state of tune ever for a car like that. 😂

[@Chris-qr3qh]

ive slowly been tuning my own engine of the same size. So far its at 54.1hp so 711.8 hp per litre.

[@jwalster9412]

I mean, it's probably better than the 600cc compound turbo i3 with 0 can profile I made.. because for some reason it redused to make any power of I went high can profile.

[@eldinmuller7698]

@@Chris-qr3qh is that on nitromethane? i've gotten the 76cc engine up to 39hp with compound turbos on e85. the torque curve is horrendous tho

[@Chris-qr3qh]

@@eldinmuller7698 Yeah its on nitromethane. Messed with it some more and got it to 58hp so around 763 hp/litre

[@CherryGS]

@@eldinmuller7698 i got 38.8 on E100 with Supercharger + Turbo. Torque is more or less constant from 8k to 12k rpm (21-23 Nm). It's quite driveable in Beam if put into a lightweight chassis (got 307 kg for the car). Would be very interested to see the 54hp variant ;-)

[@GermanTopGameTV]

You basically build a UAV engine. Absolute light weight, way to expensive to go in a car, exotic fuel choice and super high frequency noise that will dissipate over short distances, thus increasing the drones stealth. The only issue is you mounted it in a Balkan shit box lol

[@CWINDOWSsystem32]

I guess this was the fate of the engine from the MQ-9 that was downed by Russia over the Black Sea a couple of years ago.

[@MarieAvora]

75cc is a cube with sides of ~4 centimetres, for reference

[@tfs2348]

So it’s like one of those mini engines that those people build that cost around the same price as a real engine of that size? 😂

[@supertornadogun1690]

And 1000cc is a cube with sides of 10cm, wait something seems off here

[@doylerudolph7965]

@@supertornadogun1690 it's the cylinder size, not the block size.

Sounds like a Trabant with a dentist's drill for a supercharger haha

[@averytiredman4857]

A supercharged... go-kart engine? Btw congrats on second child on the way, and happy new year!

[@constructionbootgazer]

Maybe a series where chat chooses an IRL car, and you develop 3 different motors for it from tuned OE to OTT. ie: Miata NA was voted. Engine 1 would be the stock 1.8 with boost or cammed/stroked. Engine 2 could be a 1.0L superbike motor. Engine 3 could be a 5.0L v8. Export to BeamNG and lap all 3 versions around a track to see which one is fastest or suits the car the best.

[@toughtntman37doesanimations]

Bro is accidentally farming interactions with the extremely minor "pull" mistake (myself included)

[@automotiveflux]

Yeah... People really love to point out mistakes

[@toughtntman37doesanimations]

​@@automotivefluxa lot of channels exploit that by intentionally making small mistakes to farm comments

[@mcezlla8192]

This is basically a really efficient shop air compressor. If you took the boost and let it out instead of back into the engine

[@Loloskye1]

5:15 increase the intercooler it helps

[@lohenriksson9698]

You can finally make Go-Kart engines

[@indigomizumi]

Not till we can make two-strokes.

[@nogardmarith]

sounds like a dental drill at times

[@mikloskiraly425]

Centrifugal superchargers were done dirty on export.

[@gbeving3167]

Any of the supers are funky in beam. I've traced the random overheating to custom grill mods. Everything else seems to work fine.

[@Enderdragon91]

I would also like to add that when tuning you should be looking at the 4 graph mode to help show where your air flows and fuel map sit. It helps a lot to be able to see where your restrictions are, and you van only see the turbo/Supercharger efficiencies in that mode iirc

[@doylerudolph7965]

yeah he had like 25% flow utilization on all measurements but didn't restrict any of them further (which would have helped move the power band into the usable rev range).

[@z-trip5457]

Its not even a lawnmower!

[@oneonlycargeek9057]

[@drgbllgt]

It's crazy how little you understand about Automation being an Automation youtuber man, there's so much stuff you could've done to make the engine viable. Also, when you try out the engine you have to bring up the "RPM Target" slider for the engine to rev up and hear what it sounds like.

[@RDKSP33DY]

You said nitro is the best fuel, but I think compressed gas gets more power, since it has a significantly higher AKI than any of the other fuels

[@RDKSP33DY]

Also, throttle doesn't do much if your RPM target is set at idle

[@PJM257]

Compressed gas does happen to get the best thermal efficiency, but nitro makes the most power. Octane rating is just how much compression the fuel can handle before it self-ignites; it has nothing to do with stored energy.

[@ByPaco10]

It would be cool to increase the possible RPM on automation

[@vladimirgunnar7015]

i hate the supercharger sounds exported in beamng. good video

[@robbiemer8178]

Congrats on kid 2! Apart from the sound, this is quite impressive! An engine with the displacement of 2 shot glasses (well, 2 1/2. :) ) making 30 hp is wild!

[@jwalster9412]

6:28 just a random thought, but in pretty sure thise headers have less width than a metal straw. that that size pipe would probably be hard to sorce irl..

[@thegame5017]

Try tuning the manifold and headers, better flow will give you more power

[@aronhoward1194]

It's so funny that the sound of a car makes you THINK it is fast

[@Armi1P]

"We're gonna do a pull" Presses start, doesn't rev up the engine. WTF.

[@boibybee9036]

Yoo, wsp!! 30 seconds, already here LOL Your amazing Automotiveflux Edit: also supercharge the magnum opus!

[@roboman2444]

Looks like BeamNG needs a higher rev limit for small engines. Also a 100cc i4 would be neat.

[@meehdrescher]

after some fiddling, I arrived at 41.3 hp and 24.5 Nm crank: billet steel, conrods: titanium, pistons: forged light, balancing mass 50, quality 15 comp: 11.1:1, cam profile 100, springs and lifters 0, rpm limit 12k, vvt all cams, quality 15 sc, single, 280 hp intercooler, centrifugal, clutch, comp size 31.4mm, ratio 15.40, tuning 2, boost 0.75 bar, quality 15 injection, multi point efi, per cylinder, fuel map 44, timing 100, quality 15 nitromethane, nm90, race, manifold size 62 tubular long, header size 21, single exh, 9.52mm, no cat, no mufflers, -15 quality works by the narrowest of margins

[@PlaneCereal]

The rpm target is what’s screwing the sound test, gotta give it a little throttle then crank up the rpm target or just click the pull button

[@StereoTyp0]

I have been having a blast with the alpha, although some of the mid-engined body styles are bugged right now and almost nothing can fit in the engine bay

[@jaydagreen5216]

all the noise, but no speed. -Civic owners.

[@kingawsume]

The ear bleeding sound is more the centrifugal super versus the rev limit. Anything with a centrif is ear-rapingly loud.

[@Z50_Loopin]

the big bore i just did on my childhood z50r over the weekend was only 72cc so this 3 cylinder is huge in my books ;)

[@bauerbergeron]

So... CVT is the fastest transmission based on my testing, with under 3000 horsepower and an extremely ultra duty cvt pushed me to 470 mph without NOS

[@alexmagee5743]

I think if you increase the fuel it would work. That’s a lot of air your shoving into a small cylinder bore, probably needs more fuel

[@Damiantjuh]

[@Damiantjuh]

@@rawhidelamp yeah

[@Damiantjuh]

@ToiletBowl-fi5vm i think there are also a few 70cc's making 30 or sum like that

[@eristiles]

I think you should do an economy performance sedan 200-300 horsepower 2.0 L - 2.5 L turbo Another idea would be a performance built hatchback 150-250 horsepower 1.4-1.8 L turbo After that, another suggestion would be a sports sedan 250-400 horsepower 2.5-2.8 L I4 turbo Or 3.0 - 3.7 L supercharged

[@NukeTshernobyl]

You can change the volume of the forced induction separately in the audio section of BeamNG.

[@DouglasWalrath]

that engine in beam ng sounds like a really angry housecat

[@GzeeBRII]

76cc Twincharger is possible, it gives you 60HP and 36NM 30/32/5 0/2.1 for the variable ball bearing turbo and 200/1.6/16/2.0 for an clutched roots supercharger. maybe you can squeeze a little more

What about the next engine would be the best sounding engine now that the update brought the turbo and supercharger.

[@RizzinMoms2]

Click the Pull button to hear the RPMs go up instead of the throttle, when you do only the throttle, it does nothing...

Surely a turbo would be better, superchargers are driven by the crank. A supercharger with way more cc than the engine would provide significant parasitic losses over any hp gains, surely?
