[@SpecialEDy]

Im late to be adding this, but you should google "Yamaha YICS" (Yamaha Induction Control System). I have an old Yamaha SECA 7500 which has YICS.. It's essentially a tube beneath the intake ports which connects them all. The bike has ITBs with carburetors, the YICS tube is 1/4 the cross sectional area of a single port. The job it accomplishes is creating swirl and turbulence in the intake charge, the opening in the port is angled at the valve in such a way that it deliberately disturbs the airflow in the port.

This is an interesting take on induction tuning. My 2007 Triumph Daytona has similar connected runners on the exhaust header from factory. By attempting to equalize the average runner pressure you are giving up the high pressure reflected wave that arrives at the intake valve at certain rpm. However, you are also reducing the low pressure rarefactions that exist at all other rpms. Perhaps you will win the battle of averages. I'm excited to see the results. For additional study you might be interested in the intake manifold found on the 2002 Ford Focus SVT. Similar packaging to what you have there but containing a two stage runner system that I found to be clever in its operation. It's a curved runner extension that rotates out of the way at higher rpm. Good luck. I am subscribed 👍

[@seanb250]

I really like your attitude about learning and sharing so I can share some airflow formulas with you that are engine related 👍 First thing you always need to know is the cfm demand of your engine at peak rpm, this formula will give you the answer in 28” test pressure (flowbench standard pressure) of each cylinder, so what you need each port/runner to flow to support that particular rpm point. Cubic inches x rpm x 0.0009785 / number of cylinders = cfm demand at 28” test pressure. I do Australian in-line 6 cylinder engines so here is an example of the formula. 240 x 6500 x 0.0009785 / 6 = 254cfm at 28” test pressure. Next is how much air can flow per square inch of cross sectional area, again at 28” test pressure the most you can flow is 146cfm per square inch, so for my above example I would need a minimum cross sectional area area of 254/146= 1.74”squared. Now this is 100% efficiency through a straight pipe, so we know that ports and runners aren’t straight so I personally aim for a 95% efficiency, so if I want to still achieve my 254cfm target at 95% cross sectional area efficiency the minimum cross sectional area would actually have to be 1.83”squared. So if you want to ask any questions I’m happy to try answer them 👍 if you put up the engine specs and rpm points then we can calculate areas required.

[@StandRacing]

Really appreciate the detail in the response. I believe I've seen that formula before, how do you alter it to learn the cfm requirement of each individual cylinder and thereby the minimum velocity stack diameter?

[@seanb250]

@@StandRacing that is the formula for each cylinder, that’s why the final part is to divide by the number of cylinders 👍 So for my example I needed 254cfm per intake port.

[@seanb250]

@@StandRacing or if you know the individual cylinders cubic capacity then you can just put that as the first number and not have to divide by the total number of cylinders, again my example then would be, 40 x 6500 x 0.0009785 = 254cfm Because each cylinder of my 240cube 6 cylinder engine is 40 cubic inches.

@@StandRacing just remember you want slightly bigger as getting 100% efficiency from a port is extremely hard, so if you shoot for say a minimum diameter of 35.5mm (assuming a circle) then the engine will pull power to that rpm if the port is stable and the intake isn’t choking it 👍

Ford Australia was using variable length intake runner manifolds on their mid 90's inline 6 sohc 4.0L all the way up to the last of the Barra's, with amazing results. As you mentioned the 180 degree turns are a problem for air speed, Ford's early versions of the system got around it by effectively splitting the manifold into 2 halves using a vacuum operated butterfly valve arrangement, providing a short straight in between the turns to help recover that airspeed. Subsequent versions obviously only got better with the ecu handling the control of a now completely mappable, servo driven butterfly valve.

[@sirhamsteralot3977]

If we are going electromechanical, maybe giving the rx8 13B-MSP intake system a look might be an idea, it uses valves to vary the intake geometry at certain RPM's to increase power. Specifically the HP/6 port version of the engine does this. The manual is actually available online for a quick look and might yield some inspiration. Should be in the Engine Specifications manual ~Page 75 if i remember correctly

[@sirhamsteralot3977]

Actually looked into it a bit: All 13B-MSP engines got Sequential Dynamic Intake System (S-DAIS) for controlling the secondary and auxiliary ports, and the variable intake valve. The primary intake is used at low rpm only. The secondary port starts operations at 3750 rpm after the shutter valve would open. The high-output engines have the auxiliary port which would open at about 6250 rpm. The variable intake valve is used to lengthen the intake manifold and for increased mid-range torque. It would open at around 5750 rpm (at 7250 rpm for high-output engines). Variable fresh air duct (FAD) is one more intake system which you can find in the high-output versions of 13B-MSP. It opens a special valve at around 5500 rpm to shorten the air intake manifold. Together with the variable intake valve, they increase power and torque at high engine speeds. Varying the effective length of the intake runners based on RPM then may give better response/power Source of that snippit: www.motorreviewer.com/engine.php?engine_id=102

Also with the ASA, possibly some basic troubleshooting might help with layer separation. A nice dry filament and a heated chamber are necessary, as well as the right build surface (PEI sheet works quite well). But these might all be things you've tried already so IDK.

[@professionalseal8230]

can second this, only on small parts can you get away without a heated chamber on ASA. for me i've found 60c works alright, but to do ASA well you really need 80c enclosure temp, if you have the enclosure space, try and go for radiating heaters instead of fan heaters, fan heaters create a draft in the enclosure and will increase chance of warping in your prints.

[@StandRacing]

My chamber is enclosed and it gets some heat from the filament dryer which is inside the enclosure. Also, I'm in the desert so the filaments stay pretty dry anyway. Off the print bed, the ASA usually looks pretty good but I'm more worried about it splitting over time under the heat and vibration in the engine bay.

Please check Yamaha's YICS system. It would simplify and add lightness to your system. Also some manufacturers use flapper valves to open and close air ducts to keep the intake volume and air speed matching with the engine's demands. The plenum itself in one thing, but another equally important thing is the ducting before the throttle body. Surface area of the air cleaner, restriction of the air cleaner, air box ducting etc. And all this needs to match with the exhaust and cam lobes without forgetting the ports themselves and the combustion chamber. Having a vortex right before the valve seems good on paper, but it also creates a low pressure area right where the flow should be as laminar as possible. If you want to mix the fuel better, the best solution is to move the injector(s) further away from the valve, and have the port finish slightly more coarse. Rougher finish on the port wall decreases the laminar flow area, making the true CSA number smaller than measured value. Simplest way to deal with valve pulse is to rifle the whole runner. If you spin the intake charge, it will travel further distance forward after closing the valse than it would with full laminar. Also the valve pulse dissipates into the low pressure area in the middle of the port/runner. This works best with a single valve per port, dual valve system can dissipate the pulse into the pre chamber, and adding the YICS to it, the intake charge keeps moving forward. How and where? By removing the stock injectors and connecting the holes with tube, you'll have fully functioning YICS. Installing the injector into the choking point you have in your intake design, you make the perfect mix, and can get rid of both the solenoids and the extra piping.

at 1:50 ITB sizing is not like calculating the size of the stock throttle body and then divide the area by the cylinder count. The stock throttle body is a near constant flow device. As 4 cylinders pull through it through 720° of engine rotation and many times more than one at a time. While a single throttle body has to flow the entire cylinder filling in something like 240° duration, at all other times it´s doing almost nothing, there is lag during the valve opening and until the entire runner is at a common speed. So the 960° duration of a 4cyl with a 240° intake valve opening per cylinder looses it´s average flow substantially and so is not a direct correlation.

Your rationale about the outside air channel is pretty sound - in aircraft intakes this is called a splitter plate. You're forcing a new boundary layer to grow on both sides of the splitter. Remember the fluid velocity at the surface is zero and then increases to free stream in the middle of the channel. If your outer channel is too narrow there is a chance it will choke and limit flow rate, but experimenting with different geometries is easier with 3d printing! Good luck!

M1= M2 . Mass replacement will pull air from the small gap between the runner intake. I wouldn't pull air upward; with the resistance of flow and high surface area your just gaining manifold pressure.

Keep up the good work.

[@stevesloan6775]

Where is the 3d printed model shown in your cover picture?

[@hondatech5000]

Excellent work. I like the theory. Is it going to be maf? I think that and the plenum both will be a restriction. If it’s supposed to be a boost manifold then remove the itb and put a single large tb and no maf. Work on the length to generate the power at the rpm you want. Really anxious to see your results.

[@Pipitarutor]

I really want to see this made because I'm interested, but I have a few points. Revving to 6k would mean the solenoids actuate 50 times a second. That's asking a good bit out of mechanical solenoids. The thing with venturis, my thought is that if you want to get a good enough venturi effect to actually move some air through the smaller tubes. The air flow through the restrictions would be so hampered that the sum of flow would still be lower than just a regular intake.

[@StandRacing]

The solenoids won't need to open and close quickly. They will be 100% open over ~5k (as long as the throttle position is near WOT) and 100% closed under 5k. So they'll only open and close once per gear shift. I don't know for certain but off the cuff I agree that the original venturi based design would flow worse than a regular stack.

[@phopelain]

GOod point. Not something I had thought about when looking at it. @stand this would be cool to follow up to see if it works or not

[@Carter_Racing720]

If you could do clear you could also use smoke to see the air flow

[@gorkuhmork]

i would change your injector location to being much further away then what you have it if you could. a straight shot down your stacks would be best it would increase fuel atomization and would make your air much cooler going into the engine

[@vladkruglov7719]

Would be cool to see how different collectors impact on power, there's the typical 2jz hypertune style and then there's the k20 where it comes from below then in the middle. What if the intake was itbs but with a exhaust manifold or a merged collector 4-2-1? Lets see them on a dyno!

[@linearburn8838]

Try PET -CF IT has good heat tolerance It will handle up to 450F

[@MsArchitectschannel]

Most European Engines (including my custom ECU tuned supercharged MX5) Stop injecting fuel if the throttle was no longer being pressed (i had mine set to

as soon as I saw the side view I thought INTEC

[@matejmechl9345]

What about a golf Ball dimples on the inside of the turn. If you know what I mean...I think it can help sticking the air on surface like a golfball does

ASA annealing? Painting a thin layer of solvent on each layer?

Golden ratio for your spirals.

Have you ever done any 3d printing with MJF?

[@Devills_hill]

Self thought best taught

[@seancollins9745]

I could share my BMW intake design with you, but if I do, then, it must be done under NDA, and it should add a ton of power, without a ITB setup. It will match the power RPM and performance however.

[@bravosemtex6727]

Hey, can you try contacting b sport and or Kyle engineers, get some help from them. Both of them have f1 experience and I think they are the smartest car guys on KZbin.

[@StandRacing]

Have tabs open with their pages on them right now, we'll see what they say 👍

[@Oatmealism]

I just wanna see it running with the intake on it.

[@limesta]

Your solenoid should be closer to the intake valve, less volume stuck on throttle close the less throttle hang you get and better responsiveness

[@StandRacing]

I was thinking the same thing. The only thing I don't know is how cleanly the air can flow through the solenoid. If it dirtys the air a lot that might be a factor on placement.

[@jetstream321]

is this similar to what's in the e34 m5?

[@jameswhitesell3076]

What program are you using to design your intake

[@StandRacing]

Fusion 360 free version

[@jameswhitesell3076]

@@StandRacing ok. Im trying to get into the intake market for gen 3 hemis, and feel like ive got some good ideas

[@davidmurray199254]

Try xtech CF Nylon for the plenum.

[@StandRacing]

I may go that way, it will increase the material cost by a lot but I think only CF-PA, CF-PP or better can handle boost pressures.

[@Ratkill]

12:20 Also worth mentioning that a huge proportion of those gatekeeping and harassing car fam online don't actually know what the f they're talking about. So many of the folks that have a problem with whatever car for whatever reason "oh its a piece of crap" or dogging on people with ideas citing some misremembered boomer myth, never actually bring anything to the culture. Its usually the "Just throw money at it" crowd who have 50k into a car that runs 11s and is on its 3rd transmission

[@zero-twentysix]

We need to get over the idea of "succeeding at school". School should be means to an end, whatever education will help you in reaching your goals is important, but being good at school only gives you bragging rights unless you have a use for the things you learn.

[@Eli-kr5bm]

Is what Mercedes Benz was doing in engines like m272, I bet there’s a lot of research about tumble flaps

[@dalem04]

Whilst all your ideas seem interesting and possibly sound, can I suggest something? Real world data trumps all. Figure out some way to test the actual airflow you're getting into the engine. Then it's simply a matter of building the thing and measuring, and you don't have to guess. Some kind of airflow measurement at the intake to the airbox and then right before each throttle body maybe?

[@skater4life2360]

why not try same thing to the exhaust?

[@dark_one1337]

as a Mechanic I see some issues in yer Design, yer secondary Runners are connected tae the wrong Main Runners, when the valve closes the air column won't stop, ye should go with the firing order 1-3-4-2 tae create an additional Pulse in the Cylinder that fires next. the other thing is yer idea with the Solenoid, wich is simple but ponderous, if ye take a second set of Throttles for the Runners and connect them with a Rod tae the Main Throttle, yer absolute 1:1 (or what ever ratio needed) all the time. Look up the design of Turbo intake called "gap sucction" type that uses slots on low rpm so the slower column gets sucked through the long runner and on high flow or in this case ,boost occours it get's pushed through the slots, it's bassicaly a syphone ,donnea ask me how exactly that works I'm no flow engineer.
