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'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.

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'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

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.

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.

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.

This might sound strange, but I think this might be a popular mod for engines used in racing lawnmowers. In the USLMRA, mower engines are usually cam-in-block which really limits what can be done with the valves, but the cylinder heads can be modified in every way imaginable as long as they're the OEM heads that's being worked on. Combined with an aftermarket flywheel with adjustable ignition timing there's real tuning potential, even more so when using a SmartCarb which self-adjusts to maintain the optimum AFR.

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.

This is so cool, Id go with a car with a non-interference engine. The Miata 1.6L and 1.8L fit the bill. Also, with the DT signal you record its probably best you do something like linear interpolation. I think MATLAB can do that for you. GL with the build, can't wait for the next episode.

Quick tip. Having so many magnets/openings in the timing wheel is going to create a lot of "noise" in the timing system. Most likely the issue you had with your initial trial of the optical sensor setup. You should be able to get away with using only one magnet/slot and adjust your code to work with just the one input signal per RPM. I would continue using the magnetic pickup but install the sensor over the magnet that's already installed in the flywheel for the ignition system. If you can get it to work it would really simplify your setup. Otherwise continue using the wheel you made with just one magnet in it.

You should definitely get the Miata since you seem to be leaning towards it the most! Do what makes you happy bruh! Then drop an LS1 in it to build the free valve setup for in order to make US happy too!! Best of both worlds. Besides, the LS1 has been put into so many different platforms, your project will reach the masses. I've never seen anyone crossbreeding a Mata motor into anything.

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.

The stock cam profile will be a good starting point, but I had another idea. As it sits it's probably difficult to do variable valve lift as the solenoids are just on/off. So what if you just measure the acceleration of the valve as it opens and closes with the solenoids. Once you know what that profile is like you can essentially map cam profiles using those fixed ramp rates. That way at higher RPM you can use longer durations than at lower RPM, or even vary the pulse width to do throttleless operation. As for engine, I vote LS because that will by far give you the biggest splash for your channel and profile. If you can put a freevalve thing on a 4.8 and spin it to 8 or 9k rpm you'll be on every publication around the internet.

I hope you’re planning on turning those “sine wave” profiles into more of a square wave. I didn’t hear you talk about it, if you did. Keeping the sine wave, standard cam profile will deliver the exact same performance as the cam/push rod/lifter combination. Using a square wave profile will deliver the absolute most performance possible with standard valves. Losing that overlap will help too, unless you plan on going forced induction(it’s possible on these engines!).

I'm sure you've already thought of this, but... It would be great to start collecting cam data from various manufacturers for different rpm ranges. Picking and merging different profiles for differing RPM ranges is going to produce some incredible dyno graphs.

On your note, I'd be interested to see how it does on an old VW Bug engine - as that's what I drive. My hope is once he has this idea figured out, it could be applied to pretty much anything. Maybe even make kits to pretty much bolt-on to any engine, sort of like how most classic cars have kits available to convert them to modern EFI (I have done so with my VW Bug). Any engine for which aftermarket cams are made, this could be made for (putting said aftermarket cam manufacturers out of business).

@@zomgz932 Totally agree - this has so much potential. I commented on the previous video that this guy should quit his day job immediately and go into developing this full time. As for impossible cam profiles, there's still limitations of physics, valves cannot move or accelerate infinitely fast, and if it is slamming against the seat or open-stop something will wear out very quickly. Cam profiles are as they are not just due to what shapes cams can be machined to, but what is physically possible and mechanically reliable. So they'd still need to open and close somewhat gently, but if they can do so at any time and any amount that could offer all sorts of interesting possibilities. As well as optimizing for any conditions, there's also the possibilities of things like Jake braking or closing the intake valve part way through the intake stroke to control power, making a throttle unnecessary and the engine more efficient. And like you say, valve profiles for all conditions could be tuned on the fly on a dyno, maybe even incorporate algorithms or machine learning to automate the process. It would be like tuning fuel and ignition parameters through the RPM and load ranges, rather than swapping a cam.

LS is my vote, because he could possibly do only one cylinder, run the engine at idle and slowly bring his valves to life. As soon as he has that cylinder up to power he can install an 8 cylinder kit using the data learned from the test cylinder. Overhead valve engines have lots of oil that would have to be controlled (maybe cutting up the cam using it's journals to stop the oil flow, or remove the head and plug the oil feed) 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 and you only have to remove the rockers and push rods. I could see issues with making an end cap to seal off around his valve actuators and the valve cover so the mass air flow gives the correct reading on the test version. Also to push a valve open on the LS may require something other then a plastic mount unless his system eliminates the valve springs and physically pushes and pulls the valves open and closed. This is very interesting to say the least.

Having control of the valves lets you close the cylinder and start it without an electric starter. That might not work on a 4-cylinder, but should on any V8. A highly accurate (and no-touch) way to track the position of the valve while it's running would be to use a optical encoder sensor and barcode on a stub mounted to the valve. TDC/TDB can be registered with the data stream. Having this data, you can then optimize the profile at different RPMs. If you have control over other things like fuel delivery and ignition, you could really do some crazy things like up the compression ratio to 10:1 without detonation, some serious compression braking, and who knows what else.

Now you can do variable valve timing on the fly without a custom cam or other weird engineering. Not to mention you can also optimize for low demand mapping, high demand, or even cylinder shut off. I'd say the most difficult part will be determining your torque curve for a given "cam" profile.

The largest advantage of this design is that as you open the throttle the duration for both valves increases based on the throttle's position, increasing hp and torque, on the other hand it should find the optimum duration based on the throttle's position. Hint 1: low hp requirements=less duration and lift. Hint 2: acceleration will require more of each. A guy should be able to increase the power output of that little motor by a factor of 2 by simply fine tuning it by placing a throttle position sensor on and mapping the duration and lift based on it's position and speed of throttle opening and closing. Should make it really snappy as well as the ideal lift and duration will be adaptable based on your throttle input.
