Freevalve Build - Cam Mapping Tool
Вставка
- Опубліковано 29 чер 2024
- A shorter video on a few matters- First of all, Thank you so much for the support recently, I can’t thank everyone enough. I’m also looking for a car, so please comment below for what you think would be best!
Finally, I ended up making a cam mapping tool to figure out what these cams were actually doing. The result may surprise you.

Huge thank you for all of the support recently- I'm still answering emails and comments, it just takes me a bit to get through them all. Thanks!
Also if you haven't subscribed please do, It really helps!
Consider making a patreon! And i vote miata!!
@@jamesandonian7829 I would sign up for that
That's a pretty nice tool you made for measuring the cam timing events. reminds me of a cam doctor. Great idea to use that for programming your controller but unless the engine has a 1:1 rocker arm ratio you will have to multiply your measurements by the stock rocker arm ratio to give you the actual valve lift instead of the cam lift. Very different measurements.
Very clever, Wes. Good job. Looking forward to seeing what extra tricks you’ll be able to do with the HF engine. No instantaneous stop/start, obviously but CVVT should be fun. Just an idea to think about ( You seem like the kinda guy who’d be interested and might get it running ) - Laser ignition? Perhaps using a hologram window to seed multiple flame fronts simultaneously? ;-D
I'm on a page on Facebook call The Predator 212 owners group. And man we would love to see ya on the page, lot of guys on the page build these things up to 20+ hp rippers, and i know alot of the guys might be curious what you're doing cause maybe it could be a soulution for some serious power, or being creative about it. You perfect it and sell it as a kit. Either way man would love to have ya on the group
Miata. Non-interference engine. Less stuff to break when you’re in R&D.
My thoughts exactly.
The Honda D Series Non Vtec engines are way more reliable and are non interference engines as well and you have a smaller head to worry about, and it only has one cam🤣 (most of them anyway, if you overlook the D16A8 from the ED9 CRX)
Does it even matter if it is a non-interference engine? When the self-designed free-valve opens fully right befor TDC I gues the valve will be dead.
@@HansBrodiAutomotive a non interference engine is easier, because you have less to worry about...
@@THEBOZZ-zt1zn Since when has most D-series' been non-inteference engines. I understood that they are interference ones, atleast the ones that have VTEC
don't forget that the second tiny lift event on the exhaust can is only at very low rpm for compression relief to aid starting and it is controlled mechanically on the cam to "go away" at around 300 rpm for running conditions.
^^^^^ Commenting in hopes he sees this
Ah, that explains it - was wondering what that was. I've seen that mechanism on lawn mowers, a tiny cam on the cam itself connected to a flyweight, above a certain RPM it swings away and the mini-cam turns to be flush with the big cam.
Decompression?
Bsically a decompression system built into the camshaft lobe and some sort of simple mechanical inertia weights that turns off the decompression system after certain engine rpm...
I came to the comments hoping to find out what was going on there - thanks!
Do the Miata. This stuff is going to be hard enough without doing it all twice on a V8. It´s just a proof of concept anyway. And btw, I´m amazed at how matter of factly you deal with this stuff. It´s rocket science to me! EDIT: Four valve heads give you more scope to play about with things like shutting down two of the valves for say fuel economy.
Thanks! That was my thought with the Miata as well. 4 is easier (and cheaper!) than 8.
Hell yeah, freevalve yata, here we go!!!
Well, 4 cylinder with 4 valve each, or 8 cylinder with 2 valves each both ends up at 16.. But I think a inline 4 is nice and easy to acces the valvetrain, so it's still a smarter choice IMO.
@@WesleyKagan I would have to agree with miata simply because the progress will go along a lot quicker. That being said, I would highly suggest trying it on an LS at some point to target a different/bigger audience.
I'd think the DOHC configuration of the Miata would be much harder to work with than a pushrod design. Harder to fit things together, and you'd have to be all-or-nothing, couldn't have some cylinders run normally and others freevalve simply by removing or installing pushrods/rockers. And as others say, the LS and Miata both have the same number of valves. I'd suggest an older pushrod two-valve-per-cylinder four banger. Also something older that isn't emissions-regulated, as there's no way something modified like this could stay emissions-compliant on top of everything else. But before any of that, just get it running really well, reliably, and long-lasting on the Predator.
If you put this on a Miata that will be AWESOME!
That's the plan! Searching for one now.
Team dev a miata kit!
Gingum would you test it out when its finished?
Aim to put the free valve on the miata. You'll thank yourself later when you need to do actually start work on the motor
This man would become the Miata GOD
And only half the amount of cylinders, although the same amount of valves.
Your ability to execute on your out of the box ideas is really impressive. When I started watching, I expected you to be a crackpot based on how out there your ideas were. So happy to see that you are really good at this. You're an artist that paints in engineering tools. I think when you get your Miata going with programmable valves, your channel is going to blow up!
"You're an artist that paints in engineering tools." That might be the nicest thing anyone has ever said about me hah.
If I may do a suggestion, get yourself a chest mic 🎤 it would greatly help even more for the channel to be awesome! Keep up the good work
The rockers have a ratio built into them. Usually between 1.5 - 1.7. Just figured youd want to figure that into your cam specs for valve lift.
i think it might be a 1.2. aftermarket ones are 1.3 but don't quote me on it
He should be mapping the valve side of the Rockers in reality.
Yup exactly my thought... He can add the final multiplier number anyways afterward.. but atleast having the multiplier from beginning, will help the engine works like its from factory spec (or slightly from factory for better performance)
I don’t think it matters to him, his design doesn’t have variable valve positioning so all the data he really needs what the cam is doing at X degrees of engine rotation. Free valve will make the “cam profile” a series of plateaus vs rolling hills of the traditional cam.
@@jamescharron4535 The only problem with plateaus is there's some fairly complex voodoo that happens with overlap. Worse is the piston affects it, so he'll probably end up playing with overlap the most. Cool thing is he can essentially give it VVT, advance for low speed and retard for high speed.
Miata gets it done, LS gets your phone exploding with enthusiasts and a possible aftermarket motorsport empire.
Can't wait for more content from you. This is the first time getting into the nitty gritty of builds like that. And I can't imagine a better person that you showing me how it's done.
I've been waiting since Freevalve's announcement to see someone work with it privately!
As the meme goes
I want freevalve
We've got freevalve at home
Brilliant! Love to see this, especially coming from a garage. The Smokey Yunicks are still alive.
Got to love channels where a guy in a shop just tinkers rather than trying to sell you crap. Awesome content!
How have a lived in AZ with this absolute genius my entire life and never heard of him. You’re a legend and I admire your ability to create and learn so much
Never heard him say he was from here! Noice
I love how much you're going through the how you do what you do. Visualizing data helps so much.
I love your enthusiasm for engineering. If your work can find a way to replicate and document koenigsegg-like improvements on common motors, in your garage, you won't have to ask strangers what you should power. The world will beat a path to your door, and you will have the means to make your own supercars out of anything. Keep plugging away, you'll get it!!!
I'm very excited to watch this develop! DONT STOP!
The fact you are so open about sharing what you are doing with the goal of making it the best thing it can be to then also be so open to ideas by any design means necessary, is admirable and very refreshing. Nice.
I don’t care what shirt you wear or what your garage looks like. You’re making some kickass tech and that’s what really matters. Don’t let the negative comments get you down. You’re doing great!
Another awesome video! The only flaw in your rig is the Predator camshaft has a compression release mechanism on the cam. Your recorded profile is also recording the compression release "bump". The compression release mechanism is controlled by centrifugal force and once the engine is spinning the "bump" on the exhaust cam lobe is disengaged.
Very interesting, I was wondering about that. I plan on omitting it from the final map.
@@WesleyKagan with electronic mapping you can include it at start, remove it at run revs, you can go from a stock cam to full race spec, you can be totally variable throughout the rev range and achieve profiles impossible running off an actual cam
@@davidp8157 Actually that's brilliant. These predator engines are tough to start without the compression release.
I've been a mechanic for about 50 years now. One thing I know for sure, there is nothing like having data. I have some good running sbc and sbf cams stored, numbered and tagged because there was no way to know what the grind is. Some cams saved and not labeled are unknown and basically not used because they are reground factory cams. That program you use or wrote along with a universal electronic depth gauge (like on a magnetic base or something like that), to connect directly to a computer of any kind would be very sellable. You could even add a set of "V Blocks" with precision roller bearings in the lower part of the V to set the cam in while on a bench. The person would only have to calculate rocker geometry to get correct valve lift, duration and valve overlap. A mechanic can easily mount a metal plate to an aluminum cylinder head to use a magnetic base device to read directly off the top of the valve. And, when a guy buys a new cam he can map it on a bench before installing, naming the cam grind with a part# and manufacturer. If you added a crankshaft trigger wheel and sensor as a kit he could sync his cam with his crank even in a flat head. Honestly nothing like having data.
EDIT: Thank you for these videos. It really wakes up the mind to so many possibilities
im now amazed that someone actually went ahead and got into rhe freevalve idea, ive been drooling on it since its pretty dope but it didnt make sense the way that it was originally designed (pneumatically actuated, hydraulically locked) and honestly i really wanna see this in a diesel engine.
im definitely subscribing and imma have my ear to the ground, im not even half as good as you at coding nor engine thinkering but still in for the ride, mad props!
Awesome use of arduino. Can't wait to see the next videos!
Your engineering process is an inspiration, wish I had mastery of CAD and data manipulation like you! So many ideas but not skilled enough to pull it off
try autodesk fusion 360, it's free for personal use
@@bartomiejz151 I've been learning FreeCAD , lots of good resources on UA-cam , fusion is no longer free
Fusion 360 is still free for personal use. "Free startup and personal licenses for Fusion 360 are valid for one year but can be renewed annually". They have limited certain features on the free version but these should be fairly insignificant for someone learning CAD.
Love how ur tackling the hurdles ur finding in ur pathway just keep going ur doing great!
I have literally been dreaming about putting the Freevalve system in my NA Miata for months! I'm so happy that this channel showed up in my recommendations. Keep up the awesome work!
Thanks! That seems to be the winning vote, so I guess I start the hunt for a NA Miata!
This channel is blowing my mind dude, learning so much. Keep up the great work!
Dude mind blown. Absolutely no hands on experience with anything involved but I love the free valve technology..blows my mind your doing this in the garage 👍👍👍
"You wouldn't download a camshaft" is the first thing that ran through my head looking at the software copy of the cam profile.
Love it. Its good to see that you arent stuck on old designs, and dont mind making a few paper weights on your way to making something great. Prototyping is a big pain in the ass, but to some, me included, its fun and we do it on our free time.
Only found your channel a few days ago, content is really good, so nice to get into the details of your process in little easy to digest chunks. I know it takes time but clear benches when shooting parts you have developed would be really helpful for me to focus on you work and I my opinion give your genius the justice it deserves. Keep it up.
very excited to see this. One thing to remember is that the cam opens the valves gradually because that's all it can do. With the freevalve approach you can open the cam much faster (at least at slower RPM). The only limit is if you have an interference engine where a fully opened cam will hit the piston.
Some of the valve overlap timing is compensation for the fact that the cam takes time to open the valve, some is to help flush the combustion gasses out more completely.
I really love that you are giving everything to the internet like we're living in 3020 and playing along with you. You're on another level brother. On your first startup whatever values you had in there made the engine idle really smoothly. I am willing to wager that when you start it with the copied cam profiles it will idle roughly. I can't wait to see where this goes.
Your videos are fascinating. Please post more!
Excellent video.
Can't wait to see you get this working on a car engine.
Keep up the good work
Awesome! I really like the cam making tool! That could come in handy for sooo much stuff
You are doing something amazing pls keep going and dont ever think of stopping
Dude this is really cool what you're doing, I really like this series and i hope you the best in the future, brining a tech from a car that costs millions into a cheap car is amazing, great work!
I've got a 2004 Subaru WRX that needs new heads sitting in my garage. If you want it for your freevalve testing just hit me up!
That would be righteous
This sounds epic
An EJ18 or EJ22 would be non interference...
Would it fit in the engine bay XD. Wide motors already
Except pulling the engine if it needs to be redone
Awesome work! I really appreciate you sharing your code and files, too!
Holy crap love this channel basically I'm clueless to all the electronics. But been building motors most my life. Please continue with your little lawn mower motor before yo move on to the car stuff. Thanks 100% again great vids
This is absolutely AMAZING! One of the best videos I have watched in 2020!
Your channel should grow exponentially within the next year. Best of luck and this is already becoming one of my favorite channels!
It is an awesome work man. Good luck!
This is an EPIC project !!!
Brilliantly done! I wish I had a next-door neighbor like you. Keep wrenching!
I'd love to see a LS-based freevalve just to see how much power it can really make, but any miata is also a good option.
This is the coolest build going on UA-cam right now. I'm excited to see how this all pans out. The channel has 40k subscribers right now... If this free-valve engine works out the way it's looking like it will right now, this channel is going to blow up quickly... You will definitely deserve it... Great job!!!
Interesting content for sure. I am interested to see you move past the traditional profiles and experiment with profiles not possible on rotating cams. Plus RPM based profiles, like VTEC but infinitely controllable.
love it, can't wait for more. miata seems like best option but a midengine toyota mr2 would be awesome!
You're doing some incredible stuff
This is immense! thank you for doing this, and the answer is obviously always Miata
New to the channel and I like what you are doing 👍👍. Luv your sense of humour and your engineering skills. I didn't see your bio anywhere but you've obviously gone beyond middle school and are very curious with a mix of history, science and art. Good stuff. FYI a sheet of plywood with some 2x2 around the edge and a sheet of poly will contain most of the mess when doing a tear down. Then use your wet vac to suck it all up. A shallow pool for oil ,antifreeze and whatever.
I just subscribed this morning after seeing your last video and you uploaded another i hope you keep seeing videos this often great work.
This is some awesome stuff. Going to follow this project.
Consider calling it valveless design or something like that so you don't have a B is for build situations with Eleanor.
Yeah you never know. No sense in losing your own work. If I were him I may even go through every video and edit the word out most likely with something cheeky
It wouldn't be valveless - maybe camless though. From what I've heard Koenisegg is pretty chill about stuff like this, would probably be really excited to see the DIY community going for this. He seems like the sort of person who would watch from the background then see if the DIY community comes up with any cool ideas with it that he could then incorporate. Still that's a gamble though. And if there was concern about this, it probably would be more about the idea than the name - the patent rather than trademark, and there's probably no way around that as this is pretty blatantly copying the idea. Just hope they'll be chill about it.
Patent is not a concern as long as he's not selling anything. You're allowed to build patented stuff for yourself.
@@murdurer333 True. But I hope he can start selling it - I'd really like to see him (or someone) make kits to put this on any engine. And where do I sign up to get the first production VW Bug freevalve kit?
@@quillmaurer6563 Koenisegg might not care, but as long as he uses their name they are forced to care. Legally speaking, stealing the idea is a lot more murky than stealing the name. The name is an open and shut case and if Koenisegg wants to keep that name they have to go after him as soon as this gets big.
He's already putting the plans out for free and calling it freevalve. I will be absolutely amazed if he doesn't get smacked down for this. It's moved beyond just making it for himself.
Im amazed by your ingenuity... and btw the shirt was awesome
Man I really appreciate what you do. I somehow see myself in you if I was not busy with university work. Keep your videos coming! Miata would be great by the way for the freevalve setup.
Your cam mapping tool makes the one I built look very primitive. You are a master of design.
Keep it up man! Crazy tech.
Keep doing what you're doing, your channel is definitely going to blow just need to wait until you get blessed by the algorithm!
These FreeValves have been teased to us for years but if Koenigsegg wont make it for consumers Im happy to learn more about it from you!
Ya! I’ve been waiting for years for it to get developed into regular cars. It can’t be that original of an idea anyways, I’m sure people have thought of doing these types of valves for years but didn’t because it’s a little too crazy.
@@ebouwman034 I seriously don’t see the dilemma. Like they are relatively simple compared to even regular valves and cam designs so I don’t know why it’s taking so long to adopt. Is there like a lot of electrical energy they use or something? I don’t get it, these videos make it look almost too easy 😅
Your a magician. If I had money I would support your work in any way I can.
Go ahead man and very impressive way to make everything that simple
Strongly following and waiting your next video
Thanks for sharing this and good luck
I was very interested when i saw the freevavle in my recommended, something i want to do myself! I'm going to watch this series through keep posting man!
subscribed and turn on all notifications
Thanks for the support!
Same here, got your first video suggested last night and was instantly hooked. Your commitment to extraordinary projects is inspiring! Please keep us updated, hope your channel grows a lot so you have the opportunity to put more time into this. For the record I vote LS just because I'm a V8 guy but I get that 4banger will be less work. But hey you could do just one bank of the LS, keep the other one run by the cam and pushrods😂
@@Quagmire17000 LS is my vote as well because he could possibly do only one cylinder, run the engine at idle and slowly bring his cams to life. As soon as he has that cylinder up to power he can install an 8 cylinder kit using the data off the test cylinder. Overhead valve engines have lots of oil that would have to be controlled (maybe using dummy cam journals) and water pump, some oil pump and balance shaft drive issues once the belt is removed. This guy would just redesign a belt system to handle it of course but it is more work. The LS already has the cam and crank signals.
@@Ed70Nova427 very good point. Ls might be less work after all when looking at the details you mention
@@Quagmire17000 me too, been contiplating using arduino computer on my type 3 VW dunebuggy with eventually my bolt on RayJay turbo for VW's
also aditional hydrogen generator boost I built for gasoline combustion efficiency (it adds more explosion mass & because it burns all the fuel in chamber there's less heat produced & more power) correction Oxyhydrogen (browns gass) from H2O...
As an engineering student and an NA miata owner, there is nothing more I would love to see than you working on a miata! Learned all my mechanic skills working on that little thing and have never regretted owning it.
Given the simplicity of the miata's engine, amount of cylinders, and potential - I'd say you're best off with the miata! You'd probably be better off with a 1.8L just because it's ability to hold power and the fact that the engine is a bit more refined for the chassis it's in.
I'm extremely interested to see how you tackle the timing, fuel injection, and programming of the car. You'll definitely want to look into an aftermarket ECU. TheCarPassionChannel has a pile of miata information on it, tuning included, if you need any sort of guidance.
Seeing a lot of votes for the Miata, but I'd think it would be easier to do this on a pushrod engine than a DOHC. I would recommend a four-cylinder two-valve-per-cylinder pushrod engine to start out, that would be simplest to work with. I'd think this would be easier to mount on a pushrod engine, and you could potentially leave some of the pushrods/rockers in place so it can be partially freevalve partially conventional, start out just on one cylinder and see how it holds up, and if it fails (it certainly will a few times as you experiment) the conventional cylinders will get you home. My (heavily biased) suggestion would be a VW Bug engine - common and simple pushrod four-banger. But before even thinking about any of that, get it running well and reliably on the Predator, and get quite a few miles on it, or for that matter just leave it running for hours at a time (sorry neighbors...) to test longevity, ensure it doesn't die in the first few minutes.
Another BP05 vote. You're really on to something. If you're able to simplify the Free-Valve set up to where it's a matter of designing the hard parts for all the popular engines out there, you have a tremendous financial gain to make. It will redefine the world of "hot rodding"
I'm hoping to tear into an BP05 tomorrow, It's officially Miata time.
Well, youtube recommended me this video, and, not gonna lie i didn't expected anything, but your project is very interesting. It made for a great video.
can＇t wait for next video
What an awsome project. I hope you follow through with small engine to completion also
Amazing job!!!!
This is super cool!
This is such a cool project. As an NA Miata owner, I would love to see you try this on one. Subscribed!!
My suggestion is to consider what your goals are with the free valve project because we all make the same mistake of working too many projects at the same time and end up burning out. If you are going to incorporate the tech into and engine by eliminating the cam it only makes sense to choose the Chevy since it only has 1 cam and less valves to work on per cylinder which would make the entire project easier. Also if something happens and parts get damaged they will be far cheaper to replace and a lot easier to get. As you said you already have a Corvette which would be the perfect test mule and that garage doesn't look like it can hold many more projects so I would work with what you got and use the money for tooling and parts rather than another project car. Great video.
Miata would be perfect! I own a ‘90 Miata and have always wanted to incorporate Koenigsegg’s FreeValve tech somehow. Love your videos
Interesting project; one suggestion, replace the pots with TPS units, they are Hall-effect and will give you a clean, and reliable signal.
Super interesting! Already subscribed!
This is next level stuff. I'm scratching my head working on adapting a Megasquirt 2 to my my 1975 2.3L Ford motor. Meanwhile, you're prototyping Freevalve technology.
Honestly MS isn't the easiest car mod either, I did a MS3 Pro on the PorscheCart
This so so cool. Will be great to square off those profiles. No mechanical system will equal it.
great stuff this could be a game changer ... i just can believe car manufactures have not done this already... this should be the next step to piston driven engines just imagine the tuning capability ...
Great stuff. Thankful I found this and can understand.
The random stuff found on UA-cam. Really interesting work. Subscribed.
That's crazy cool!
Love the C3, and I'm a Corvette guy. BUT, the Catfish Miata is amazing. Weighs nothing, plenty of room to work (yay tube frame!), and it looks great.
Great job Wes!! I vote for the Miata as well.
The small secondary opening of the exhaust valve is likely a decompression feature on the cam used to aid in starting. Typically a flyweight that opens and returns the cam to normal profile.
Just found this channel... Awesome vids and huge knowledge! Greets from germany
The small bumps on your red map are the probably the compression release for starting the engine
This is amazing. Wanted to do this ever since I saw Koenigseg's demo on The Drive channel. Just a suggestion, you could export the data as a .csv or even .ods (csv and ods are supported by all spreadsheet processors, so even if someone does not have MS Excel they could always use something like OpenOffice or LibreOffice which are open source).
Great stuff!
Such a hard choice. Love to see either of them but the LS would be amazing
The crank shaft on the mx6 is well balanced and Porsche had a hand in its design. Basically the same as the Ford probe GT.
Make your life easier, Miata have half of complications, I mean cylinders... Keep the content quality, it just rocks. And your engineering is just amazing
Very good idea 💡
I just jumped in because this project is genuinely interesting
When fitting to an automotive engine, be sure to get airflow and airmass data before the change over. The biggest advantage of the camless system is turning the valve timing into a square wave.
Dude! Awesome! Always wanted to have a go at this Koenigsegg tech..
Glad you going with the miata! I've got one (1.6 na) and i will be closely following this!🤣
Wesley I am brand new to your channel.... Strong work, your content is very interesting and easy to follow.👍
Thanks and welcome!
