Omni Valves, weird, check it out

So, here's the link click here

And my opinion... it seems to be a pretty neat concept, would be willing to try it if they'd fix up my Javelin for me I wonder if any of the auto manufacturers have experimented with anything like this, but I will also note that old hit-n-miss engines used suction for intake valve opening and timing!
...and the discussion/debate starts... wish Doc were around for his input.

I find it interesting how they mention about a transmission less car with these valves. How would you get reverse? Park and neutral would also be nice.
Sure would like to try a set as they seems too good to be true. I guess I could never qualify for a free set as I don't have an engine shop.

Very interesting concept and the idea certainly makes sense. This sounds like an idea that one of my heroes, the late Smokey Yunich would have come up with. At least, were he still around, he'd have been first in line to get a set to experiment with.
My first thoughts were valve weight and thus high RPM use so I read with interest the testing in an LS1. But it sounds as if they could possibly make the need for extremely high RPMs a moot point, we'll see. I'll be looking for more reading on this in the coming days.
I wonder just how much piston to valve clearance is required? My 388 LT1 is not near the edge on that even at .525" lift, 11:1 and zero deck, due to the nicely designed SRP inverted dome pistons. And I could always gain a bit more by dropping back to 1.5 rocker arms on the intake side.
Could my 26 mpg highway/450 HP Corvette someday get better in town mileage than my old 4 cylinder Nissan beater?

So now we have twice as many valve seats to worry about?

Did I read it correctly; that only the intake valves are replaced by these trick ones??

It appears they have found a way to incorporate essentially the same type of induction as found on a 2-stroke reed valve motor into a 4-stroke motor, allowing entry of mixture based on cylinder/manifold differential pressure instead of a strictly mechanical means.

The site is somewhat confusing to me (at my age, there are a lot of things that are confusing to me) and I would like to see a simple video of specifically how the thing operates. If it's there, I couldn't find it

I've found rotary valves... sounds interesting as well.

I don't think either one of those are "new" ideas because I can remember reading about something similar back in the '60's but maybe they were just ahead of manufacturing technology back then. Could be that maybe with todays materials and manufacturing abilities their time has arrived and this definitely will be worth watching.

haha, I just had a guy (an engineer in the automotive industry) tell me he came up with the idea for rotary valves, the company he worked told him it would never work.

The other valves sound neat.. but too good to be true, like many other things.
If an engine can run on pressure differentials (I guess only the intake side) why the need for 100's of pounds of valve seat pressure to close/seal those bad boys up.
I wonder how well that little o-ring holds up in there.. hmmm.

I'd like to see some hard numbers by a third party.

Maybe we could start a Hotrodders R&D fund. Pool donations to test new parts.. Then post results in a database.
