I feel like you're looking at the airflow around the intake wrong. Instead of looking at where the air goes (some of it diverting to the side of the intake) consider why it goes to the side. Pressure difference makes air move, if there isn't any pressure difference air won't move. If the air is diverting around the side of your intake it's because there's higher pressure in front of the intake and lower pressure to the sides. There's two separate things at work here: A velocity stack is designed to take relatively still air and get it into a tube as efficiently as possible by minimising the turbulence as air coming from the sides tries to make the turn into the pipe. It's purpose is to prevent turbulence and maintain laminar flow. A ram air intake's purpose is different, it's there to turn kinetic energy into pressure. You probably want a ram air intake into an airbox of sufficient size and then the engine drawing air through a velocity stack from the airbox which will be at positive pressure from the ram air. A jet engine intake is a ram air intake but a lot of the design in a jet engine intake is to slow air down from near transonic (or supersonic in some cases) to subsonic so the engine's compressors can handle it. This won't be a problem at road, or even race, car speeds. My guess would be a velocity stack style intake on the most vertical part of the front bumper (stagnation point) feeding a tube that increases in cross sectional area as it goes to an airbox would be an your best bet. The rate at which the tube feeding the airbox gets wider would need to be calculated to maximize pressure recovery.
Yes hence my examples are the lesser super sonic ones not an sr71 or an f16 and on to the intake “why” it goes to the side All I shared is running a velocity stack front faced at the track isnt an “ideal” thing to ise Like you mentioned and as I mentioned in the video it was meant to be efficient at around “still” or “stagnant” air not “forward” facing like most Honda racers do, On the dyno yeah it helps as the car is strapped down…pardon me if the English sentence structuring isn’t ideal on the video 😇
whoa an E92 awesome!! and yep on this vid hopefully the "diagram" of all diff bellmouth entry can give you more interesting ideas TBH i was surprised at the highest rated one
@@SRDmotorsports I was really interested to see how much more airflow the ellipse had than the other designs. I found the paper you got those flow pics from and they had some guides for the dimensions to go off.
@@ScottGroome oooh will def update in the future to see changes on airflow mass change if there is any or do we need "more" Great you saw the papers awesome!!! if it helps, I use what its called i think Sintra board its sorta like a foam on varying thicknes and used that to make patterns/plugs then painted primer to be able to mold... might be usable for you even when making an airbox :)
You are a true genuineness I have learned a lot from you I like to think outside box on everything I do too and I have now come up with my own intake system 👍
Oh thank you man!!! Truly appriciate that… I like to share what I try or atleast design and talk about ideas…I guess a lot of “experts” talk more but explain less and maybe they should be questioned lol (fb experts lol)

Interesting. I was running a carbon fiber intake on an all motor car a couple years ago. I was running a 168mm tb, and even then I thought it was too large but I ended up making a PSI on the map at high speed. I like your break down. This is interesting

Thanks man had to redo another video like this as the earlier one I explained not as much detail actually there was not much explanation on the earlier videos 🤣
Nice video! I still think your radius might be too large on your intake at 14:04 , as we see on the forward facing F1 car intakes (above the driver) at 9:07 to 10:20 , the radius on the inside in particular seems to be pretty small. I don't think you need a velocity stack where it goes down to a circular profile inside the duct, but rather an efficient contraction profile that's perhaps more smoothly blended into overall contraction as it shrinks down. That's a really cool intake any how though!
Yep the stack shape isn’t really needed for forward facing… the stack inside though was mainly to aid in reducing the contraption into a circular pipe, I just did mention I used a small stack as shape source for it hence the oval intake I made is mainly for max cross section available and def worth a few tests :)
Enjoy your videos thank You. So the theory is your velocity stacks with stagnant air or an enclosed department you run a flared velocity stack with taper And in a forward facing you don't put a taper just a Just a radius entry with no taper?
Kinda yes almost like that… in forward facing atleast based on datalogs I got for the Honda b20 we did At 12.1sec and over 114mph it was still not enough that it still showed -0.4 reading A vacuum when we know at those speeds if all is good we should be slightly above atmospheric sadly nobody talks about that or shares it 😂 We used the cf 4in stack on that datalog
oh Whoa!!! thanks man :) i kinda didnt mention JPM of sweden that has some trick IDF and IDA velocity stacks that has an annular discharge trick simply cuz costly ☹️ but very interesting too! Actually all this? was first triggered by my curiosity on my bug and since we cant run it with a forward facing intake? without a massive airbox it made me wonder and research and the rest was history 🤣
Awesome video! Really informative. Thank you! I just wonder if there are any upcoming topics about ITB with plenum?

as u said velocity stack is meant for stagnant air from your cfd we can see pressure after velocity stack is increasing and as we all know air like to travel from high to low pressure as we have high pressure in front of the car we want the opening to not close but open up so we have lets say 4" opening to suck high pressure air in we want the tube after opening to increase in size to lets say 5" this way air will be sucked into the opening best way really is to utilzie air box so we have opening same dimater as intake piping that is leading to air box where air expands and lowers pressure and from there after the filter a velocity stack that will suck in the air into the manifold

most often we see increase in power from intakes mounted in headlights or bumper because of colder air not as much from amount of air especially on headlights air actually is sucked out because body of the car makes it travel to the side and as we get colder air it is better for the effeciency of the combustion but we dont get increase in pressure inside of the intake manifold i installed tube that is sucking air in front of radiator into the airbox compared to original intake that was runing 960mbar im getting 988mbar when above 30kmh but the air that is hitting radiator have other ways of avoiding the intake pipe because radiator is not sealed but even with that i got an increase in pressure but i have to service the intake monthly because airfilter is getting clogged with sand and pretty much everything that is on the road
it’s also the length of the intake that helps but with a proper one I have seen datalog of increased pressure and it’s logged with 2 diff pressure sensor locations etc even on the dyno the increase in power isn’t because it’s cold only but also the length… Yes the headlight location isn’t most ideal as shown in the video it gets swayed to the aside (airflow)

But air flow is air flow- I can't rely on speed to get velocity, but have to use other tricks for Low end TQ and fill cylinders. It's just for fun/hobby, I don't compete. Have you ever read about something that would maybe help the front facing stack? I could be way off here, lol, as you don't see this in front of jets or race cars, but maybe play around with shapes in FRONT of the hole, that split the air, then behind it (where intake would be) gather up that air from it being split.

I agree on hard to rely on speed for that but “taper” and bellmouth stuff u can slowly use to ur advantage! on the second part yes I have seen that video and it’s real nice and what’s funny is it most understood it? then more would have a “proper” rear diffuser 😎 but sadly some just “copy paste” the idea without understanding it

Then you have done something correct, lol. And it's ALL about thinking outside the box.
@@rustygehl yes sirrrr! Wish the jeep had enoug engine bay space for a CAI which I talked about on the “volumetric efficiency” video as it gives a 4k rpm jump in power u could check it and prolly “upset” more peeps on the dyno haha

that's an interesting observarion yeah... could help a bit but the diff is my drawing of the forward facing? the outside lip becomes a diversion too... towards biasing "palabas" but yeah thats a good observation
the other main thing with what i did was "cross secrional" area a bigger area = more volume hence example were the race cars that knew what they were doing :) first to run 8sec All motor on Drag Cartel means Jeremy lookofsky knows whats up 🤣
@@SRDmotorsports my original plan was to adapt a velocity stack to the intake. But now I’m going to extend the inlet about 2 inch’s forward of the front. Get clean air that hasn’t been affected by the boundary layer and misses the propeller by an inch while stacking air.
thats funny cuz an initial design like that came from one of a schools "formula student" team etc but even more interesting the initial shape of the intake before the plenum resembles my intake OMG 😏
it is also one of the many thing i constantly research and follow... formula student teams/research as they usually have a fresh untainted perspective like that video you showed but isnt FSAE ofcourse i just meant the level of innovation is there :) now imagine the Intake design theory? + this ram air design? i havnt seen your vid prior but hmmm interesting right? :)

Research "Schauberger's Whorl Pipe"... that coupled with your modified velocity-stack intake, is the key.😘

Wouldn’t those bends slow down air speed? Or does it do the opposite?
not sure
would this design see the same effect in a turbo charged application?
different approach on turbo as it’s “feeding” a turbine unless the turbine is right at the high pressure zone it gets too complicated

@@SRDmotorsports my original plan was to adapt a velocity stack to the intake. But now I’m going to extend the inlet about 2 inch’s forward of the front. Get clean air that hasn’t been affected by the boundary layer and misses the propeller by an inch while stacking air.
@@alexhuey6489 now u got something there!!! Yes and that slight extension would help “stack up” flow too! win / win
Interesting CFD modelling and design here: th-cam.com/video/g_C07YCNWkc/w-d-xo.html 🍻🍣
thats funny cuz an initial design like that came from one of a schools "formula student" team etc but even more interesting the initial shape of the intake
before the plenum resembles
my intake OMG 😏
it is also one of the many thing i constantly research and follow... formula student teams/research as they usually have a fresh untainted perspective like that video you showed but isnt FSAE ofcourse i just meant the level of innovation is there :)
now imagine the Intake design theory? + this ram air design? i havnt seen your vid prior but hmmm interesting right? :)
@@SRDmotorsports Same thoughts about the similarity with your intake design. Also, looking forward to the results of your testing.
@@SRDmotorsports By the way, are you using CFD modelling or fluid dynamics software for your design?
@@findtherightbeat actually no im merely using the oldschool pencil/paper and measurements back n forth
cuz the physical product is the main challenge
its why i envy those with 3d printers 🤣
What's your Instagram because I would like to get one off those you made. The drag cartel design
Lemme get back at you as I dunno my IG by heart especially cuz it’s still not totally “car stuff” related but I’m slowly turning it into one lol
@@SRDmotorsports ok I like the one you made for the b series with the eg
@@SRDmotorsports at 14:19 in the video on just like that
Oh I see that now
