SUPERCHARGER and TURBO power gains in Stormworks

[@DataDownLynk]

how a turbo charger works. you have 2 snails, one's very exhausted, the other is a blowhard. They're conjoined twins so whichever way they turn, they turn together.

[@454ss_gaming]

Totally :D Thank you for the comment! I gave a super dumbed down version for the sake of explanation how it could work with Stormworks! XD

[@DataDownLynk]

@@454ss_gaming I really wish you could push a fluid through an impellor pump and get an RPS output.

[@taliakuznetsova7092]

​@@DataDownLynkyou could until they got rid of it due to infinite power and instead of fixing it they removed it.

[@DataDownLynk]

@@taliakuznetsova7092 I know it used to be a thing. but still makes no sense cause you can get infinite power out of a steam turbine by looping the steam back in.

You can actually get much better efficiency when using impeller pumps (especially with the large one) on a smaller engine if you use a clutch to reduce the load the impeller places on the engine with a clutch. It also helps if your ECU can alter the amount of fuel the engine gets on the fly to regulate the Air-Fuel-Ratio (a must when using an impeller pump if you ask me) so that the RPS of the impeller and with it the amount of air the engine gets doesn't increase so fast that the engine begins to lean out when the RPS of the engine rises rapidly.

[@454ss_gaming]

Excellent idea :D Thank you for that detailed response! I will have to try that for sure!

[@marctardif9756]

Could also use a dedicated generator with a clutch (clutch lets you adjust engine load), using that dedicated power to run an electric motor at a PID controlled RPS. All you then have to do is find out the minimum RPS needed for maximum air flow/pressure without wasting power. Along the engine power curve, there might different RPS/clutch settings needed but I havent gotten to testing that yet.

[@billybill8227]

Just like in real life, when running boost on an engine it may struggle to keep the AFR up because it may be maxing out the fuel injectors. The solution to this is to add a better fuel pump or more fuel intake manifolds, and this applies to stormworks as well. If anyone wants to use the larger impeller or pump, you don't exactly need a larger engine-it really just depends on the quality of the fuel delivery system. When running smaller turbos with smaller engines, you can benefit from having an ecu that is preloaded with a turbo tune, such that it increases the fuel manifold throttle proportionate to the boost that may be generated by rpm, or manifold pressure. The upsides for this system is that it allows large boost on small engines, and steady control of the power the engine generates; the small impeller on the V8 was inconsistent-something that this setup may fix.

[@Zorro9129]

It would be really cool to see just how much power one can squeeze out of an engine of a certain size.

[@Bendigo1]

It should be noted that just adding a pump to the engine does not automatically make it more powerful and can actually cause the engine to not work at all because the afr may be too high. With all due respect to MrNJersey for what he has done to help others learn, That ecu is really outdated and overcomplicated. I have made several for my own builds that are more simple and work much better. So learning the process of getting the correct AFR is essential for anyone really looking into getting into modular engines. Something that I have found is that if you use composite nodes ch 1 and 2 from the engine for air and fuel, multiply it by the number of cylinders then by 60, you get the flow rate in L/S of fuel and air. That can be useful for determining afr in a larger scale. When you add a pump to the fuel and air, the fuel will be limited to the fuel manifold setting, but the air will be increased at any setting. So you need to increase the fuel manifold value to get the proper afr. Adding air pumps allows for a higher volume of fuel to be burned per cycle, so instead of maxing out at around 0.45 to 0.5 fuel manifold setting, you can usually get upwards of 0.6 fuel manifold setting before it becomes too rich. Small fluid pumps and one fuel and one air manifold works great for small engines, but 3x3s and 5x5s need much more air and fuel per cylinder per cycle, so one air manifold, one fuel manifold and a small pump per cyllinder is reccommended and can actually be mandatory with large engines. On 5x5s it may even require 2 per cyllinder.

[@454ss_gaming]

That is key! I just wanted to compare apples to apples, but yes, I have heavily modified NJ's ECU design for my creation with smaller vehicle engines :) Thank you for the amazing insight and comment!

[@ishanegi1735]

your reply was very helpful , now i can further work on modular engine for my prop plane, thanks :D

[@levimccallum7722]

my two braincells just realized that it's technically possible to turbocharge a steam engine... *hell, they already have something similar for when they're sat still!*

[@454ss_gaming]

XD hahaha

[@idriveamerc]

look up turbocharged burn barrel, i think thats a good example of what your talking about and its genious machine 💀

[@Adesterr]

First, before i start my "rant", i want to say that i really like your videos and especially your design constrains video. I fully agree on this topic with you. Torque doesn't mean torque in this game. There are multiple theories what it actually means and my take on it is that it represents the inertia mass of the pipe system. There is a theory that it displays the mechanical resistance, but that can't be true as flywheels will add a huge amount of "torque", but almost no resistance. There was a brief moment in the development process of modular engines where the devs tried to implement turbochargers and didn't quite succeed. They tried to make the impeller pump work like a turbine if fluid pressure was applied to them. I think they never got the balancing right, because they were afraid to implement yet another infinite engergy source into the game. I tried everything to make them work back then, but it was never possible with how they were implemented. Look at a cylinder of a supercharged engine. If the AFR is oscillating, then the intake pressure is not steady enough. The stoichiometric will be constantly over or under your desired value. The power output will fluctuate, which can make something like a traction control quite tricky. The small fluid pump (3x1x1) is not well suited to supercharge a modular engine as it will shut down at a pressure of 10. So, the pipe fills to a pressure of 10, a little bit supercharging happens and the pump turns off, the pressure drops immediately and the air intake is starved of air. Then the cycle starts again. Same is true for the large fluid pump, but it works better in this configuration as it turn off when it hits a pressure of 999. The small amount of air these tiny engines take is not enough to bring the pressure down to the maximum supercharge pressure (something around 100 or 200 pressure). But you will run into the same problem with larger engines if you don't use a bypass (variable fluid valve). The impellers don't work very well on this scale as they will need more rps and therefore more power of the engine as is shown in this video. Or else they will also create the afr oscillations. However, no matter the scale, large fluid pump(s) + bypass will allways outperform impellers in the usable power output and therefore also the fuel efficiency. It is just that the advantage gets smaller, the larger the engine becomes. What you completely missed is the air scoop. Facing into the direction of movement, it will create enough intake pressure at relative low speed to supercharge a modular engine. If you put a engine on a carousel, then it should be enough to see a noticeable power increase. They are small, easy, cheap and use no engine power for the supercharging.

[@454ss_gaming]

Thank you for the well thought out response :) Glad you enjoy the videos, more will be coming soon! Interesting about the turbochargers, I didn't know the devs were considering them. And good advice, thank you - I will play with the variable fluid valve, that sounds promising, especially with the large pump! And excellent point about the air scoop, that is something that I have not played around with, but sounds worthy from what you mentioned! Thank you for the comment!

[@StormTrail]

Doing Great! Growing fast keep up the good work!

[@454ss_gaming]

Thank you :D More to come soon!

[@LukasKolcRacing86]

I love the mention of a Saab

[@Zorro9129]

This makes me want to experiment with a V12 engine and try to make the fastest possible supercar. There are some very impressive cars on the workshop but I don't know how many make full use of superchargers.

[@francescomoretti-sd9nb]

5:28 there is a belt pump for modular engines, idk how powerful it is but there is one

[@454ss_gaming]

Excellent point, I never actually tried with that one, I only used it for the coolant :D

[@yourbigfan1777]

I have just tested it, i'd say it's more powerful than NA, but it's quite unstable (or maybe that's just my ecu tripping). It's better to use the impeller pump imo

[@thegdog368]

so anyone know of a good ecu to use? all the ones i keep trying dont wanna work well. some will let the engine run, some wont even idle.

[@captincheezee]

Just some useless input: "Prochargers" are actually called centrifugal superchargers -- ProCharger being a brand, and have different power output than a standard twin-scroll belt-driven supercharger irl -- Prochargers act more like a turbo (aka they produce more power within a certain RPM range, but still with linearity), superchargers produce more linearly (aka they produce power strictly according to the input RPM). Also, instead of using a standard fluid pump as an electrically-driven supercharger, you could theoretically use the impeller pump with a small electric motor, all hooked into an MC that increases the output of the motor as you need more power (or the engine spins faster). Would look cooler (and probably perform better) than the basic fluid pump. Something to try!

[@454ss_gaming]

Great input, love forced induction :) That's a really good idea to try out! Thank you

[@captincheezee]

@@454ss_gaming anytime! I'm biiiiig into making engines on this game. I do find it funny how you can "bypass" the game physics and make something with forced induction, haha

[@yourbigfan1777]

Man can't wait till they add an actual turbo, this would reincarnate many of my builds

[@fairlyoddme3021]

Since the way fluids and gases have changed... Could you redo this test? I'm curious to see if any change

[@technicaldeath6539]

Love your Tahoe!

[@454ss_gaming]

Thank you! If you want to see it more, here is a video I made of it :) kzbin.info/www/bejne/hp_dmqGtrZ2oi6c

[@Valixo889]

I havent played stormworks for a while but couldnt you get the flow rate of exhaust and use formulas to control a impeller pump to create similar power to a turbo?

[@Fransenn]

what about the "coolant" pump for the engine as a spuercharger? it it the same as a small impeller pump i wonder

[@philippeguerin9373]

NICE bro i did a LOT of tests too HAHA heres some observations ! When boosting the engine, gotta change the AIR FUEL ratio ! never found 100% efficiency again while boosting but i found way more power out of large pump changing AFR !!

[@arpioisme]

What about modular engine fluid pump? The one attached to the end of crankshaft

[@ZhiLawd]

They could also have the delta of out to in pressure (pump reversed) produce rps

[@stormtastic7083]

superchargers also look cool on the engine

[@454ss_gaming]

Yup!! :D

[@2dquix]

i always use the large fluid pump on my engines(not custom just the default medium engine) so it it technically turbocharged?

[@ibuildblasters8118]

it would be nice if we had a power output belt part

[@homeopathicfossil-fuels4789]

You got Saabs in the US? They are awesome, swedish company, they make really great military hardware too. Generally swedish companies make impressive systems. There is a belt drive pump part in the game, I normally run coolant on it but maybe I should consider driving air with it instead and keeping coolant electrical instead so cooling effect isnt RPS dependent but constant

[@454ss_gaming]

Yup! Saabs are awesome cars :D I will play around with that actually, I only saw it as a coolant pump but you are totally right!

[@mythical_mattress]

I’m supercharging my v50 now, any tips?

[@super_loaf2]

i have learned something new.

[@ibuildblasters8118]

but yknow what it would be nice if mounting impeller pumps together WORKED like it should

[@fcdrummer1806]

i typically see the bigger pumps work better on the larger engines like the 3x3 cylinder engines.

[@Scaveged]

What would happen if you have a supercharger and a turbocharger in the same machine

[@454ss_gaming]

Look up the Lancia Delta S4! Twin-charged means the engine had both a supercharger and a turbocharger attached to it. The car made over 600 horsepower

[@Scaveged]

@@454ss_gaming wow

[@craz33ivan93]

The one's not working needs more fuel to make proper power, and it should make the most

[@aniripilot9886]

This feels like bad science. Wouldn't you want them at the same RPS? At different RPS the effectiveness of empeller varies a ton. I would put a microcontroller controlled clutch that keeps them all at 15 RPS or something like that and see the torque values then.

[@shortysrandomvids8752]

these only work on module engines standard old ones they do nothing as far as i have tested any way

[@Jackbrowwn]

if i were to make a 7 ton suv that needs alot of power and want to have a speed of 30-50 what would be best?

[@Lynx-w3d]

Taho would not keep up with a viper

[@454ss_gaming]

The Viper was pulling away, but it was not an embarrassing loss

[@itisinickt]

how is it possible you made so many custom engines that are worse than the basic small engine? my small engine makes 63 electric on a small generator

[@454ss_gaming]

it is not all about power output for me, it is to make something that is reliable and stable for the creation :) But yes, there are ways to optimize and make it better

[@patnaty]

Need a controler to control boost and mixture at same time

[@454ss_gaming]

Good point, thank you :) I will look into this!
