Building & Testing a V10 Engine With LARGEST Bore and SHORTEST Stroke! (Automation | BeamNG)
ฝัง
- เผยแพร่เมื่อ 17 ต.ค. 2023
- Today I will be attempting to build an engine that has the largest bore and shortest stroke combination possible in Automation to see what kind of engine we end up with! I decided this needed to be a high revving V10 and boy was I surprised by the results of this absolutely ridiculous stroke to bore ratio. I ended up putting the engine into the ONLY car it would fit in and turning it into a track monster to rip around in BeamNG! Check out the video, let me know in the comments below what you thought, and I hope you enjoyed watching this as much as I enjoyed building the engine and !
Thanks for watching the video! If you enjoyed it, make sure to like it, share it with your friends and give me your feedback in the comments below!

0 horsepower at 10,000 rpm🔥
just pure noise baby 😂
Motorbikes be like
Obviously never rode a real bike 😂@@v_stands_for_value124
Backpressure: Well hello there.
IRL that engine would be dead mid pull. big chonky holes in the piston glands.
Maximum efficiency😂
To rev high you need max flow everything and the lightest possible moving components, cast light and billet is where it's at👍 a big turbo can also help but then you need heavier internals again.. cast block and heads are good actually, not for weight but strength. The torque dropoff is that the cams are too Conservative.
im only at 6:54 right now and so far with the basic intake manifold it will suffocate at higher rpms -and the exhaust will also slow flow at higher rpms as well- i see he fixed that
exact
high end numbers are actually due to valve float. the valves arent CLOSING enough to actually make compression, hence all the power falling off. you actually need to LOWER the size of the lobes on the cam and increase duration. that way they are open longer, but just not as wide. a smaller cam lobe at super high rpm causes less float because it's not trying to slingshot the valves with a baseball bat. ive been building engines since the 90s, some at low RPM, torque monsters, and some that push over 9k. very very different geometry to keep valves happy. a cam'd drag car with 1000hp at 5000rpm has almost the opposite cam profile as 1000hp at 10,000 rpm.
You could try to make the slowest revving engine. My old neighbour tunes old tractors and at one point he had a small tractor that drove around at like 100 rpm or something, it sounded hilarious.
That'd have to be reaching into the V16 dlc, right?
A Ford 9n? They are known to rev low
Like that video of an old diesel running at 0rpm lol
the old john deere 2 cylinder J tractors had the best "kerplunk" noise when they idled
To make power at high rpm, you need all of the air flow you can get. To make the engine not explode at high rpm, you need the lightest rotating components you can get. We’re all here to learn!!
More than rotating, reciprocating mass needs to be kept very low at high rpm.
This sounds just amazing! Maybe you could do a challenge with the boys where everyone must use the same vehicle body, but each can build their own engine?
And the engines are limited by a build price?
So cool to see you all having fun with this! If you soften the valve springs and and raise the cam profile it will move the torque curve further up the rev range and get you a lot more power and torque, you may have to lower the max RPM a little but you'll get way more performance out of the engine! Keep up the good work Cosmo, love to see you having fun with it!
Thanks for the comment and the tips!! :D
I really like these series where you kinda learn as you go and build on it. Kinda like Kan's piston engine videos in scrap mechanic. Feels like I'm learning with you, and my adhd brain is terrible at learning lol ETA: it kinda looks like a loooong renault 5 lol
Thanks for the comment! haha yeah I can see the Renault 5 in it xD
Variable Valve Lift would be better known by one of its trademarked names "VTEC". Two separate cam profiles for the intake valves (not sure if they have VTECd the exhaust side on newer engines), driven by a oil pressure lockup actuated by a solenoid. Rev speed will be driven mostly by rotating mass, which includes flywheel weight, piston weight, and connecting rod weight. I get kind of a "Lancia had a baby with a Citroen rally car" vibe. It accelerates so slow for being so loud: literally my IRL car lmao. Yeah, those gears are waaaayyy too close together. I would start by lowering the ratios a bunch, and once the shifts are in the right spots, fiddle with the final drive ratio. You could do the maths to figure out the correct ratios, but where's the fun in that?
lol my IRL car is the same xD Thanks for the tip on working out the gear ratios!
@@darealkosmo If you do it right, you should be able to get those ratios figured in two iterations (gearing is either maths or iterative). I always start with the "I've gone too far" step, then bring it back 30%, but you could try a "cut it in half, then half, then half" approach also.
@@darealkosmo VVt is basically the power valve on your 2t
VTech is just Hondas trademark name for their VVL, they did make it popular to do. Other Japanese manufacturers also had a version of it, Nissan and Toyota both did in the 90's.
Fun fact: Rich=Colder Lean=Hotter
This is because of the cooling effect of the fuel evaporating
One thing to know about Pushrod configs is that they aren’t optimal for high-revving, high-load applications. This engine worked but OHC can be more reliable for these stats.
Good work!
Really? Pushrods can't rev? You've never looked at AA/FD or funny car engines. 12k is pretty much normal at 300+ mph in a 1/4 mile.
NASCAR only recently switched to OHC engines. they ran pushrod setups at 9000 rpm for 500 miles straight at full throttle/200mph for YEARS. they're just REALLY wicked rods haha
@@ghomerhustThat’s a race application. I meant that the pushrods can bend and flex if not made from good enough materials.
@@buddcochran4726You’d be right. But generally, DOHC provides better airflow for high RPMs.
@@buddcochran4726 Plus, race engines only do maybe some number runs before a rebuild.
I don’t understand why he refuses to use the quality slider if he is in sandbox mode
The variable valve time is for better efficiency through the whole range as opposed to high or low. You would use variable cam lobes irl tho
No… it’s strictly for better performance and maximizing torque.
You would use vvt-variable compression and variable lift which is two to three different cam lobes.
All of these can be combined to make both power and more mpg.
I got to 46mpg with 300hp before shops started taking apart my engine.
You should look up videos of high RPM motorcycles. Like the 4 cylinder 250cc bikes that rev 17 or 20k, I forgot. And they had the same "problem" too. They sounded like they were going fast, but they weren't. They are the engine epitome of "It's better to ride a slow bike fast, then a fast bike slow". Small motorcycles in general are so fun. But those extra small 4 cylinder bikes were old & rare, until Kawasaki recently made a new one.
I used to ride a CBR250RR that revved to 19k :)
@@darealkosmo
Luckyyyyyyyyyyyyy.
Same with the ZXR250, 45hp peak and 38hp at 18k rpm on the dyno.
Sounded like the old F1 cars.
SUV?
My boy, that's a Wagon.
Absolutely love this ridiculous car.
I built one of these long ago, it ended up being 758 hp at 9800 and 498.2 fpt at 7000 rpm, those are exact numbers. I used my data from My RSX Type S's non stock K20A2 engine and the TODA short stroke kit morphed in to a V10, I settled on 89x77mm 4790cc, Dual 69.8 mm exausts 11.5k RPM 15:0:1, cam 92, VVTL 100, ignition was 76, 6mt with top speed of 425 kph 0-60 2.2. AWD 22/78, AFR 11.9, ill leave the rest to you but I did fine tune the crap out of it and fit it in to a lotus Exige chassis made by Aruna. I have all the stats but I figure I gave enough for you to put the rest together, or at least people reading who know what they are doing. Most the other stats are optomised for breathing and 15 quality ofc. I am just about to rebuild this in the new version as I have not played in over a year.
Will edit:
This engine above was on the old version, I am happy to give out any statistics. Right now I am in the process of re tuning for the current version of automation as of 07Feb24. Manually tuning VVT is a pain, I will watch some Hondata Kpro tuning vids before I finalise. So far I am at like 950 HP and 650tq, this is far too high, I need to stretch it out I am far too light for this wheelspid, I am running sports not slicks.
I am not sure why I am making so much power. If I can not stretch this out let us all have a moment of silence for my chassis.
I know everyone reading is wondering, It drove terrific in the old BeamNG, I have too much power now. I am scared to optimise. I am not even sure how as I was trusting Camshaft Studios wizardry.
I need to load the old version and check the suspension, Updates may be a pain for all but how do I gain 200 HP and 400 TQ. I may have to rebuild the engine smaller.
From 1957 to 1965 Chevrolet made a mechanical fuel injection for 1957 Chevy cars and Corvettes until 1965. You can find cutaway images online to see the complexity. All said though, the engines made more than 1 Hp/Cu in. and were capable of high fuel economy and, surprisingly, often met mid to late 1970s emissions with only a PCV valve. FYI, I'm a retired old school mechanic.
Imo you should've went with tubular exhaust bc it not only looks super cool but also sounds amazing. I also would've went with slightly larger header size for better resonance (71-73) and even a bit better flow on cast low headers.
Trust me, auto mechanics is fantastic to get into, being self taught in my opinion is one of the best things to do, you learn at your pace. My brother taught me the basics then i learned anything else from the internet and my own truck i bought. I know about the springs and lifters some, variably valve timing is crappy, if you can mess around with your own tune you can definitely make more power and have it run smother. If your springs are stiff they will be harder to move obviously and return to they position faster and with more force, not a great thing but you don't want weak springs.
It honestly turned out much better than I expected 😂
He made a modified box with a V10. Props to you, man.
You actually achieved greatness, 0 horsepower while the engine is screaming its lungs out.
Loving this series!❤
Did you watch any of the videos besides this, that came out years ago?
OMG was waiting for this!
Again, you need to build some more cars, Kosmo, and then join in on Camodo and kAN's BeamNG videos and just show up in your twerk truck. It'd be absolutely hilarious and like your best video ever. Get kAN to be fun again (tell him I said that as if he'd care.) But I can just see the whole Infected game mode they play with you in it and, "Who's it? Who's the infec-... Kosmo. What on earth are you doing?" "I'M GOING AS FAST AS I CAN!!!!"
hahaha. I actually did try to join on infected butttt my PC can't handle 14 people in one BeamMP server :(
@@darealkosmo Noooooo! That bites, but you'll definitely have to do it once you update your rig. I kind of want to share one of my builds. I was going for a beefy truck and Automation and BeamNG seems to think I was joking. A stupidly mahoosive 7964.11cc V10 overhead cam 3 valve turbo charged with a 9.18 cm bore and 12cm stroke length. It's limited to 6300 rpm, but it some how is throwing down 736.7 horses at 5400 rpm and a whopping 927.5 lb-ft (1257.5 nm) of twerk- sorry, torque at 3200 rpm. I tried it out at Johnson Valley thinking I got like a super duty or a gnarly Raptor. . . . The thing don't work out on Johnson Valley. It easily gets up to +100 mph in 2nd and I've had it zipping across the salt flat at +200 mph. It, in theory, should be decent on dunes. The problem is it yeets itself off even the smallest berm. I think you'd have a lot of fun with it because it's just accidentally so stupidly fast.
did bro rlly say bitten by a bee, love the vids btw keep it up man!
Looks nice to tow trailers 😂
"5.6 liter, that's pretty big" laughing in both American and big boy diesel (semis and heavy equipment)
I love automation. Earlier versions had videos that explained all the details and how they affected the engine. I miss those😢
Hoping they add gas valves for really high revving engines.
Also: importing cars from automation into beamng was the greatest thing ever omg!
Driving your engine really shows how shitty they are😂😂😂
I love it Kosmo and the sound is straight out of a F1 car 😂😂 I love it.
Please make another car and engine maybe the smallest bore and the longest travel? 😅
I dub it "the barking hearse"
Fire engine🔥🔥🔥
Reminds me of the four-bangers around here; no speed, all noise.
Every door is a different color and you could fit a coffee can in the tailpipe
Kasmo you should look up the v12(maybe it was v10) benz trolling hypercars
You should build the most performant 1 cylinder (whatever the fewest cylinders you can have) you can manage.
16:00 looks like a hearse, so thats my new head Canon that you made a racing hearse from scrapyard stuff. Also you'd be surprised the stuff that can be found at a scrapyard. At least in my area finding a trashed rally car isnt too uncommon.
Edit: 150+ km/h is slow? In what universe is that slow? Admittedly I'm basing it on high way spreds here in Sweden which tops out at 120km/h
V10 4 liters something? It's 250km/h top speed minimum.
You should always merge your exhaust with a V configuration. And I mean always. The closer to the engine you position your merge, the more torque you'll make. The further away, the more HP you'll make. Its been proven time and time again to be the best configuration. Port matched headers into a merge, out dual. Another thing, connecting rod destabilization has to do with harmonics and the balance of the rotating assembly. Ive never played this game. I'm speaking reality here. However in a simulation format, the laws of physics should be the same as they are in real life. I have no idea if you're able to balance the rotating assembly or not. Ive seen you mess with the harmonic balancer settings which might be the move if you're running into high connecting rod stress levels. I'm actually an ex Marine but since 2016 I've been an Audi mechanic. They sent me to Germany for 7 months to learn the R8 inside and out. I'm proud to say I'm one of 5 men in Nevada who is certified to work on the R8. I'm the only certified guy in my area (Reno, Nevada). So believe me when I say I know my shit. If you or anyone else has any technical automotive questions feel free to ask. I'm always happy to help.
Is this possible in Automation?
You should learn about VVT. It's actually quite simple once you figure it out haha
Yo you litterly made me spit out my food bro lollll when u said the exhaust looks like a garden rake it had me dead😂
big bore, big valves, big overlap, big exhaust, big throttle body. This has been the Honda recipe since the early 90s. Your problem is a lack of exhaust momentum at higher rpm, the rods experience stress because they aren't moving a piston freely, they basically ram the piston in the exhaust stroke like a second compression stroke which completely sets off the engine balance. Especially for a v10.
Only builds 2 strokes: man of culture
But still makes a naturally aspirated engine🤔
Get the guns. The pistol has the lowest damage, the single shot rifle is great for sniping. The shotgun is brutal at close range. I rarely use my spear any more. I have refined armor and helmet as well as the Giga Shield and a protection amulet that adds about 10% to my HP... which is almost 2800. I try not to enhance a Pal until I have an Alpha version. You can redo dungeons after a few days and you can back out of the boss chamber a few chambers to spawn a different boss if you do not like the one it spawned. I have a lot of Alphas... like 30+. I am running out of space in my Pal Box. I have a lot of Kings and Queens too. I just hit level 39, but I was focusing on base building most of today. I was tired of the Pals putting stuff in different chests so I built a refined metal chest and made sure it was the closest and put all the crafting materials and seeds and Pal bits. The other chest has everything else. I have over 130,000 gold. Yes with a flier you can get the effigies (especially when it gets dark) and eggs.
There is an interactive map and it has "most" stuff on it. I did find 2 caves that were not on it yet where the queen bee is.
did one of them have guns in the back of the car
Wait, you've only built two strokes? Same here! Well, not built a whole engine but ive had one apart. To change out the... Seized piston, on 2 different 50cc mopeds. But both cylinders made it with a little honing. Awesome video btw👍
That's slick! Gotta love it when it's just a hone. What mopeds ya got?
@@darealkosmo a Peugeot speedfight 2 and a honda mt5. The speedfight is mine and the mt5 is my fathers.
@@darealkosmo i don't know how popular they are where you live but here in Sweden they are pretty popular. Atleast among the younger people.
You could get rid of the white part of the logo around the face cam, to be just a black silhouette, so it's much cleaner.
Maybe if an x-pipe exhaust was possible, it made the 90’s nascar sound like Indy cars.
Hey Kosmo to help a bit with fuel injection. Mechanical fuel injection means the injectors fire/inject mechanically basically once fuel pressure reaches a certain psi it opens up. Single point efi means there is 1 small opening on the point of the injector nozzle and efi is electronic feul injection. Multi point operates similat to single point except it has multiple holes on the tip ie more fuel and beter spray pattern and atomization. Lastly direct injection is just fuel is directly injected into the combustion chamber. Whereas single point and multi point in automation is port injection. Hope this helps.
thanks d00d!
🤣😂🤣😂🤣
Single point EFI is, at it's most simple, a carburetor with a fuel injector instead of a carb jet. A lot of hotrodders experimenting with EFI use systems that resemble carburetors, bolt up to the same place on the intake manifold a carb would, but spray fuel instead of fuel sucking through a jet from a pressure drop in a venturi.
MPFI places individual injectors right before the intake valve. These are either mechanical (a special pump driven by the serpentine belt that sends fuel at high pressure to the right place at the right time) or electrical (the injector receives an electrical signal to open a valve inside of it.)
Direct injection is modern mechanical fuel injection that places the injector inside the cylinder head, after the valving. This uses a mechanical pump driven by a lobe of the camshaft to shoot fuel directly into the cylinder under very high pressure.
5:57 you know what else go brrrrrr
GUN GO BRRRRRRRRRRRRRRRRR
Short stroke, big bore = perfection.
The ideea is great and i actually made my version of this engine and it became a beast, i made 600hp and it can go from 50km/h to 300km/h in one gear. One thing i noticed in the video was that esc was on comfort and was beeping all the time, it had no power cuz esc was cutting it
What update are you on for all the material options?
The front looks like a VW Jetta ^^
ha true!
i dont have the cast light materials there and the testing screen looks different how did you did that it looks like that?
Engine has the power but the transmission is what needs work.
Can’t wait till this guy figures out he can build the engine in engine simulator and export it to this game 😂
puts me in the mind of an 80's ford cosworth somewhat.
You could use higher cams on the VVL at 7000rpm so that it doesn't choke the engine
Cast iron isnt necessarily the worse material. Actually very durable, just really heavy.
Kosmo would you watch an engine Tutorial if i make one? I have a pretty good method to do good engines without alot of knowledge of these Numbers. Anybody else? Love your channel
Cars at 3:00 AM like:
You need higher cam profile and stiffer springs also all forged light components then it will probably rev to 11000rpm+
When you have max cam profile and stiff springs and valve float up the quality of the top end
Also use performance manifolds
yknow, you made me question if they modeled deisel runaway in this game
for higher revs you probably need higher quality on your top end parts. and a much higher camprofile so you get som top end torque. your gearing should be more narrow between gears and final drive should set top speed. ;)
"I only build two strokes, I've never built a V10 Engine"
*Me sitting here with cheeto dust on my chest whose never built an engine in my life*: What a loser.

Just a heads up I found when porting cars over the esc in beamng makes the performance tank
thanks!!
Fun fact: There is a model of the Cadillac Escalade that had had forward-facing brake lights. I'm not sure why, and I can't remember which year model it was, but I do remember seeing a video of it. The brake light was in the front bumper, along with the fog lights.
woah! gotta look this up now!
It’s like a fake sleeper - a slow looking car that actually is kinda slow, but SOUNDS fast lol
like my car irl! lol. everyone turns their head and becomes quicky disappointed
Multi point injection allowed to make more power during the power stroke by injecting during the entire cumbustion event… wasn’t that effective for before tdc firing motors but after tdc ignition very much benefited.
Now it’s pretty much standard equipment
If you’ve ever been rear ended before, and saw it coming the front brake lights would help to know at least they tried to stop
FF7 Highway Chase music! U playing rebirth?
What program is the engine simulator using ?
hey kosmo love your vids, can you show us or tell us like what do you do in real life with engines, love from Croatia
No?
11:22 that “whaaat” sounded like xqc
Chode comes to mind.
OMG İ WAS WAİTİNG 3 YEARS FOR THAT CONTENT LOL
I think its the compresuon ratio being so high with such a small stroke it limits power idk jsut slap a turbo lol
turbos solve all problems xD
I wonder what this would sound like with a supercharger... It already sounds like it has the cousin of one lol.
Your SUV looks like a Ford Sierra!
short stroke leads to not enough time for the engine to intake air before the valve closes. Less power. Long stroke small bore means valves duration can increase leading to more air intake.
What version is it that you are using
What we've learned is kosmonaunt makes fantastic drift vehicles. All be it slow as hell, but these are accidently cars that are more so to sound loud, look pretty and drift.
Also a month ago i3 has always been bugged for me couldnt do same settings as i4 even after tweaking boost just always broken
As much power as you can out of the smallest v8 you can
Ik a few that has a 2 stroke saab and all of then gets hate for driving in ”100mph” on a 25 area, but in reallity they are driving in 15-20mph but it just sound fast
All you need to know is this equation to produce the best displacement for your stroke. .7854xdia2/PSI or Kpa. You need to know the max pressure for each cylinder at .7854 of the ignition stroke .7854 is a quarter of PI. If you know the average pressure of all the cylinders you can set the fuel ratios correctly in any computer to make max horse power per RPM and pressure, .7854xdia2/Kpa, Get it?
There are current engines with 38 inch bore, so you weren't actually near the maximum. This 100,000 hp engine is used in ships.
Small bore small stroke direct injection race headers 8 cylinder cast iron block aluminum heads. I wanna hear it lol. Hopefully next video
I know why your brake lights are in your headlights... It's because in automation you can actually customize your lights to be different colors & have different triggers.
Damn I reeeeaaaaalllly want to see this engine with boost single turbo twin turbo whatever
So using any cam after the green without the springs and lifters up will result in valve float and killed motors 😂i always turn them up to 100 no matter if its a stock cam..helps with the top end blowing up if you money shift😂
Also the higher it revs the longer your gears need to be so spacing has to be high
Kosmo you need to look at engine parts to improve quality and light weight engine will be better
You shoulda did atkeast a forged crank that's not an uncommon thing even in cheap vehicles
A lot of the rpm band is being wasted, probably airflow.
The truck isnt exactly slow, 0-60 is about 5 seconds. The gearing also seems odd, but it could be because of the power drop off in high rpm...basically, it sounds like it wants to shift much sooner
Where can I get this
One reason you are slow is your power band is in the middle of your rpm range but your gear ratio is designed for the top end of the rpm range. My understanding is shift just after peak HP and land at or just below your peak torque. Would love to be educated further on this topic.
You need more cam and intake that's what affects the more the rpm power potential but you gonna lose lower for sure. That where vvl save the game with a low cam profile for torque down and big cam lob for rpm horsepower. If variable intake runnerwas a thing in thia game , power band can be tuned lot more.
Looks like a Merkur XR4Ti
Such a handsome fella
Kosmo i have a tip get a v10 with a 9800rpm limit with no turbo and a light weight body it can go the 1/4 in 7.2s
