Test W4Gas Cell

March 29 and March 30, 2008

Drove to North Bay, Ontario and back.
On first fill up at 546 kms I got 29.86 MPG
On second fill up at 352 kms I go 29.26 MPG

My baseline MPG was 24.2 MPG without running the W4Gas cell so my gain was 23.14 %

This is not too spectacular a gain percentage wise, but I was driving much faster than I do normally in this area which is 80 to 90 km per hour. My average speed on the trip was about 100 kmph reaching as high as 128 kmph according to my ScanGauge. These kind of speeds do not make for good mileage.

The W4Gas cell was only putting out 62 milli liters per minute of HHO at 2 amps. I can see why many are using 6 cells or the "six pack" as they call it, but it would only come out to 371 milli liters per minute (.371 lpm ) which is a far cry from the 1.7 liters per minute that the Smack booster puts out.

To get substantial improvement in mileage eg. 70% plus , I understand that my 3.4 litre engine would require about 4 1/2 to 5 lpm of HHO, so that is what I should be striving for. At the moment it looks unreachable as it is 3 times the amount of HHO the Smack booster puts out. We will see what happens as I connect the Smack to the van.

Don't sweat it. Just build it...

I posted the following to a forum on W4G and thought it may be of interest here as well..

I agree totally. For the Newbies, Build the W4Gas first , it is quite simple to do, forget about everything else for the time being. Next test and check for mileage under different conditions.

Learn everything you can about the unit you have built, for example....Check MPG in the City without W4G power turned on, then check with W4G running. Do the same with Hwy driving.

Check amperage being drawn, quit worrying about voltages with the W4G unit. Amperage is determined by the amount of baking soda used and can be read with an inline ammeter.
Here are some things that I have learned that may be of use....
City driving 15.95 mpg W4G turned off.
City driving 23.42 mpg W4G turned On.

Output of W4G connected to Intake Manifold gets me 15.89 MPG
Output of W4G connected to Air Intake after air filter gets me 25.04MPG.
Interested in hearing from others that have checked this out.

Noticed sudden increase in amperage to 6 amps running Windshield Washer Fluid in jar. Checked, found lots of gunk in jar and the jar was so hot that I could not handle it with bare hands. Removed jar and replaced with new WWF, 2 tsp of baking soda in another jar. Current was around 2 amps, no heating of jar in next 50 miles.

MPG can vary considerably due to outdoor temperatures like we have in Ontario. Once you have fairly consistent data from running W4G, then start on the other things that will improve your mileage.

All the above has been done without changes to the various sensors. Have tried switching in the home built MAF enhanzer several times and have got dramatic boost in MPG to as high as 41 mpg on 03 Venture.

Have fun and don't sweat it... Ted

Laying Low.. too much snow and cold

March 9th, 2007

Have not done much since my last post as the weather has not been very nice to be out experimenting with the WFG Electrolyzer.

Several days ago when the sun was out, we took a run with the unit on and the MAF sensor being controlled by the pot arrangement. To my surprise, the ScanGauge was showing 40 to 41 MPG for most of the run. Sort of expected to see the engine temp rise a bit, but ony about 3 degrees. Have to do a fill up to confirm that my mileage is increasing.

I read up on the Smack Booster and liked the amount of hydrogen it produces, so got busy and gathered the parts I needed to build the SS plate array. Have that completed and need to get the container made up for it. The array is shown on the left .... is made of 16 gauge 304 Stainless Steel plates 2 1/2 inches by 5 1/2 inches. The plates are larger than the ones for the Smack as I was unable to find the blank switch plate covers used in the Smack design. It will be a while before I get this completed as I want to get more mileage data on the WFG unit in the van at the present time.
