A PCV jar kept in a cool place will pull water from the oil. I saw this when testing water injection.

A top lube added to a fuel additive mix would help lube the engine.

As far as a bike carb goes, couldn't the brass discharge tube be reworked? You know, the one where the piston needle dips into in the venturi.
I'm thinking maybe drilling really small holes, or cutting narrow vertical slots, in the exit side, might help atomization. Maybe even cutting a bevel that's lower on the exit side, so that the velocity of the air pulls the fuel out better. Maybe even a wide angle v cut, sharpening the v so that the fuel shears as it flows out of the tube.
I bet even just a bevel would improve light load throttle response.
Take a clear plastic tube, about an inch and a half diameter, drill a hole in the side to fit a straw into it, hook it up to a shop vac, and have the straw pull water from a bowl or something. Play with the design of the straw, like it's your discharge tube, to see what makes the best pattern. Who knows, maybe you'll stumble on to something big.

Edit: Anything you do to one, has to be identical in all 4 carbs, or they won't perform the same.

This actually makes the most sense and I thought of a circuit that only starts the HHO cell after the engine's warmed up.

Same circuit could be linked to a turbo timer unit such that the cell would switch off once the ignition key is removed, but the engine would continue to run for a short while to purge the remaining vapor.

I think I'll do a couple of rudimentary corrosion tests anyways to see how bare metal stands up to the HHO in a sealed environment.

I'm up against the wall. I have to get this head finished soon or else......

There aren't any real results as the head hasn't even been shipped yet. I have tried to work with Omni Valves with no luck. I have a manufacturer ready to do some serious production, but can't get clearance from the inventor. The Dakota head I have the Valves for will be the only set I have been given. I would like to keep them for myself, but I made commitments and have to ship them. They should be shipped within the next 2-3 weeks.

I like the idea of their swirl-inducing pistons.

They mentioned a stock CR of 8.5:1 on a SBC, and then said you can raise it up to better than 10:1 without detonation just by adding these pistons. Just imagine what could be had with these pistons and one of Mike's magic cylinder heads.

I'm going to go out on a limb here and suggest that the damage isn't while the engine is running hot, but when the engine is shut off, or possibly even when first started. Delay the onset of the HHO gas to let the engine develop a bit of heat, then shut if off a couple of seconds before you kill the engine.

The potential problems with running HHO are similar to what one would experience with running a water injection system through the engine.

Namely the resultant steam can strip lubricity. There could be increased wear in the valve guides, and upper cylinder bores. Also, I have not tested for PH yet, but I suspect that HHO is not PH neutral.

I have a water/oil seperator already. Now need to devise a system of delivering a microlube through the intake. The Goodman nozzle design sounds promising, but I'd need to make mine work without any kind of airbleed or compressor, using only engine vacuum since my engine uses no smog pump and is OBD II.

Where are the corrosion problems happening? Is the water getting into the oil? You could use a water/oil seperator. If its valves rusting you'd have to use some sort of alloy that resists rust better, same with rings.

Been following the hydrogen cell work of John Aarons for awhile. Now that the Stan Meyer circuit has been tested and proven, I've built numerous cells based on John's Widowmaker. Now in the process of putting together a cell based on his 15-plate design.

Burning Brown's Gas produces a lot of water vapor in the engine. What would be the best way to get around the problem of engine corrosion?

The valve guide/corrosion problems I've read about probably had to do with the HHO seeping into the guides during start-up and shut-down.

Also, I think these chaps are not filtering the gas properly, thus allowing a lot of moisture along with the HHO into the intake.

The PCV jar, microlube (for upper cylinder lubrication), warm-up and shut down circuit seems to be the best system if it can be implemented without too much difficulty.

I think the big advantage would be lag free boost everywhere without being inefficient.

The problem with boosting smaller engines so they cope with heavy bodies is that you get max boost over only 2/3rds of the speed range, or the supercharger is inefficient (or VERY expensive, in the case of the screw compressors). I imagine after you got the whole prototype stage out of the way, a CVT on a centrifugal supercharger would be cheaper than a screw item.

The Dodge Omni is a lightweight platform that provides incredible performance with modest power (ala Lotus). Chrysler has offered several varieties of turbo engine combos that makes parts availability plentiful. To get the most from a turbo set-up, an intercooler is requisite. The problem with the Omni is there is absolutely no room for anything but a puny token effort.

I'm doing a killer Omni GLH clone for a friend that wants one of the largest ICs commercially available for passenger cars. Where to put the daggon thing?

The stock grill was cut and sectioned, the IC becomes the majority of the grill area. The bumper was cut to clear the IC, and the frontal area reduced to improve air flow. Hoses will snake under the bumper brackets, make a 90* turn toward the rear, then another 90* turn upward. Driver's side will come up through where the stock battery box was, and the passenger's side will come up through the area where the charcoal canister used to be.

Of course there is lots of blasting, painting and powdercoating.

yup thats a bid IC i have also seen a set up where the rad was replaced with an aluminum unit more like a honda civic set up but with top to bottom flow. The rad was half as wide as stock but thicker with a low profile fan. The IC was about the same as the rad im not sure how the bottom hose was routed but the top made a nice broad 180 degree turn around the back side of the head.

I've recently hooked on up on my car and keeping an eye on it. It is interesting info and been noticing about 18" while cruising on flat surfaces....heck, can even still pull 10" while 'cruising' up hill at about 40mph.

Although, it was kinda amusing to see the gauge 'peak' when the car was backfiring for awhile.....luckily it didn't bust the gauge.

Thanks for the tip, I'll look to get one of those filters shortly.

In the mean time, I've updated my blog with the PCV Jar install.

A couple of pics:

She's installed and I'm almost a little giddy to go through my first tank of gas to see how she does.

The car did see an odd spike of 34mpg but I am not counting that 100% because of various issues I've been having with the car. The first is the gauge needle and the big one was that 2 fill-ups ago only seemed to take less gas that what it should have, giving the distance I drove. Still, we'll see if that is a consistent number of not down the road.

Right now, the car is averaging 27.37mpg (a few 10ths higher than my Neon!) and if I am to assume (yeah, yeah, I know...) a conservative 10-15% gain from using the PCV jar, I should be seeing 29-31mpg on average in the next few months. I'll keep everyone posted.

Check out the blog for more details.

Hey Gang,

I just read the results on a Dodge 360 with the grooves and I didn't see any significant gains.

http://somender-singh.com/content/view/88/37/

My goal is to have a 400-500 HP 360 and the grooves in that example didn't add much at all. Maybe I'm not reading it well, but it seemed that the grooves we almost not worth the effort.

What am I missing? Am I missing anything?

Did anyone else notice how much liquid droplets of fuel were bouncing off the back side of the intake valve towards BDC of the intake stroke, and how most of the "action" is around the intake valve? This would indicate to me that this particular engine has trouble with wet flow, and there is quite a bit of liquid fuel that had formed rivulets around the port and on the valve, which burn slowly. It is still burning as the exhaust valve opens.

It has been said that The Groove is more of a power enabler than a power producer. It allows you to run higher compression, lower octane fuel, more ignition advance, or more boost than a normal cylinder head would. You will generally gain power if your engine is detonation limited. It also extends lean-burn misfire limits, so if you are aiming for better mileage, you are able to lean out the mixture further than you would normally be able to.

Also, most of the gains are found at 1000rpm or less, where very few dynos venture to test.

A few notes on that 360 test, they compared the best stock numbers to the worst modified numbers. They didn't even post all of the different test runs for us to judge for ourselves. They were quite careful to not allow any other changes besides the grooves; including a slight milling to restore the "before" compression ratio.

As Pinhead said, the Grooves are enablers. Put another way, I call them "bandaids" as they allow easy fixes for factory discrepencies. Larry Widmer is running as much as 23:1 compression naturally aspirated (100 octane fuel) and 30 psi boost with 13:1 compression (93 octane pump gas). He uses no grooves, or dimples, or any other bandaids. However, he engineers the total engine package (head, pistons, cams, etc.) basically from scratch.
