Excellent, that is a very realistic figure. Now when you take all the moisture out of that you will have what it actually is making but for our purposes that measurement is a good one. If you put to much more HHO in the computer will start working against you and you will need an EFIE. The idea is to find the max you can put in without upsetting the ECU. If the mileage drops off reboot the ECU and dilute the electrolyte a little. Small steps here and you will find the sweet spot or plan on investing in an EFIE and increasing your mileage even more.Performed a quick flow test yesterday. Used a 1 gallon jug then converted to liters. At 17 amps and with a solution that seems to be at well under the 20% mark (got a hydrometer, too), I'm producing 1.07 liters per minute. I've upped the solution and am now drawing about 20 amps, but the solution is still barely registering. On that note, I'm almost out of electrolyte.
