From here It’s getting serious. I might try it out on a spare V8 or an engine that’s not just a single next before I get to work on the rest of the engine. I’m going to be perfecting this over the next few weeks and ironing out the code and the limitations in the processor- Who knows, I might put that year of a CS degree to work and build a self learning valve optimization plan.

I also want to work on the solenoid design, as that’s a bit more interesting than just copying Freevalve.

This is in the early stages of prototyping- but all of the files for this project are open and available to download. I’ll be updating this as I go along and will update the files and the code accordingly. For now, they can be found here. I’m always open to getting other opinions, so I welcome you to download and improve them.

    I am an engineer, and I can honestly say that so are you. Great work!!! keep the innovation flowing. cheers
  • @rayray7405
    When he first tried to start unsecured engine , I was laughing. When it started and ran well , I was not laughing anymore. He is a very talented person. NO FEAR .
  • @flyingpeter
    there is no engineer more legit that the one that tries to reinvent the wheel in his garage out of curiosity, you are the boss
  • @MrUltraDreamz
    "Im not an engineer" Designs a camless valvetrain 212 head from scratch with his own code
  • @zackworrell535
    Wesley, you are a serious geek and that makes you a very special person. Keep up the creative thinking, fearless curiosity, relentless determination, and mad skills. This world needs more people like you.
  • @AbdulHameed-kv6pr
    So Koenigsegg come up with a new valve technology and some badass dude replicates it in his garage. Wow!
  • @rayburn157
    Whenever you're ready to implement a 16 valve setup for an LS, I'd be happy to do the machine work and offer my facilities.
  • @samtimo3002
    "I dont wanna pay for cams what is other way" Proceeds to make his own valve system
  • @nhungcle
    Hey, don't forget to fill the engine with oil.
  • @oggearhound2242
    The valve tappets that you noted were "off center" and thus an error is wrong deduction. They strike the top of the valve stem off-center so that they rotate slightly at each strike. This prevents lopsided wear on the valve seat.
  • @Pags222
    I watch these videos to remind myself that I'm not really that smart. Love your unbridled thoughts and the ability to execute on them. Keep up the great work!
  • @the3odo1721
    Random YouTube recommendations actually coming thru for once. Outstanding video can't wait to see the progress.
  • @TerraRoot
    I love high technology applied to disposable engines! Build a dyno and test it. And/or blow peoples minds by using the inlet valve as a throttle valve and ditch the carb.
  • @tda2806
    Y o u probably won't find this comment, I'm nearly the 500th person. The set screws that you use to operate the valve head WILL back out. I suggest that you use 2 set screws per valve, each half the length of the current one. screw the first set screw in so that it just touches the valve and then screw the second one in above it to lock it into place, a little loctite at this point would be useful as well. The loctite will give you 2 benefits, one stopping the setscrew backing out and two it will seal the threads as a possible leak for the air pressure. I hope this helps best regards from the UK.
  • @Junkyard_Dave
    If you want to work together email me I have the thesis paper on the free valve tech from Koenigsegg, I just haven't had time to build and program a system.
  • @ReelAddict1
    This is the type of content Youtube was made for. Well done sir! Super impressive
  • @gordonjcp
    That's amazing! It runs really steadily and smoothly. Regarding your timing sensor, consider buying an off-the-shelf timing ring for converting engines to Ford EDIS and making an adaptor. That will sense the presence or absence of metal teeth rather than magnets which are going to come flying off your timing wheel at speed :-) I'd also look at using screened cable for the sensor to stop it picking up ignition noise.
