I know from my own testing it is not real accurate to just top up after 100 ks, sometimes the bowser stops short and figures are really high - but u always get a lower result next time round. So only accurate way to do it is to either run full tank right down or better still keep all your litres & klms on a spreadsheet so that they can be averaged out to give a really accurate result.

If ur interested i can post up my excel sheet that i use for this, you just give it klms, litres, & price and it calculates klms per litre, miles per gallon, litres per 100, and price per klm, for each entry, as well as increase or decrease from a given base mileage, and averages.

I'm about to start gathering the bits to build a "Smack's Booster"
The fact the engines seem to run quieter intrigues me.
Could the reason be that the mix has a much shorter burn, making the combustion complete when the exhaust valve opens? This shorter burn could be creating efficiencies by having more of the combustion energy pushing down on the piston when it counts.
Does any-one who has run a booster for a considerable mileage have an opinion on decreased life of exhaust components, inc cat. converter?
Great thread, by the way.

hho does it really make a difference i already make a trip of 850 k's to the highway to a full tank. Will this hho magdrive kit for sale at the moment increase my range of kilometers from 5% to 45%.....

I've done my research and i have found mag drive unit sells all over the globe and all the websites have all the exact same wording even same spelling errors and same punctuation errors, over the uk, and usa web sites.

Some sites i have visited say its a scam and taking energy from car battery reduces the power to power the car, here is where my engineering in the electrical field comes in.....
Just add a "12VDC Digital Capacitor" in between the connection to the magdrive unit and the battery, stops headlights flickering when on accessory problem fixed
therefore the power factor problem doesn't exist,

this is the same problem people have when they put power full sound system in their car wiring amps to the battery with out the use of a 12 volt digital Capacitor

and if you want to improve your cars efficiency there are other ways, one of them i found was increasing the cross sectional area of the negative battery terminal to the frame/CHASSIE of the car (instead of a 16mm cable you could use a 32mm or 50mm) pretty expensive move though.

Me personally I wouldnt spend the money they are asking for the kit. The best way to find out is to build your own kit and give it a go. Being an electrical engineer you should be able to knock up a basic kit and EFFIE pretty easily.
I started testing a hho kit on an old hyundai and it worked ok I am now rebuilding everything to match an AU ute.

Great thread this has been so informative,stumbled on it last night about 11.00pm and read whole thing from post 1 took about 3hrs.Thanks Garthr,Ive been studying the internet forHHoboosters for months and started building one ,a bit like a Hotsabi and am getting .350 lt/min with 12v and caustic soda.......tomorrow will try caustc potash,keep up the followups ,Cheers

Hello, I have run an electrolyzer on a Nissan Skyline 3 litre fuel injected for 12 months. The car gradually improved performance over a 3month period and from then on it performed extremely well. I recorded a 15-20% economy improvement as well as harmful emission reduction proved by two exhaust analysis tests months apart. The engine ran quietly and smoothly and I did not have any problem with any extra detriment to exhaust etc.

I am still running an electrolyzer on my 1998 EL Falcon and wouldn't be without one. I produce these kits.

Regards,
Noel

Garthr,
Saw this question about zero fossil fuels and a PWM back on page 8. I don't know if you have seen or been referred to the following already but click on the link below

He has done a constant current PWM.\\
sincere regards,

Thanks for that - i hadn't seen it.
will have to build one and see how it goes.

On the science program on Triple J recently, Dr Karl was posed a question about Hydrogen injection which sounded very much like HHO. It's on a podcast for those of you who missed it.

Broadcast/Podcast date: 2008-06-26
Link to MP3 of Podcast: http://mpegmedia.abc.net.au/science/triplej/drkarl_20080626.mp3
Podcast Reference: 22'42" into the podcast.

Dr Karl mentioned that a farmer made up a similar kit and got poor results and has basically bagged the whole concept as a con.

So much for "scientific method". He mentions only ONE reference of a failed attempt, yet disregards anecdotal evidence from a myriad of sources that prove more than 1mL of gas per minute is produced.

I've been pooh-poohed by naysayers on the Drive.com blogs as well which is only driving my resolve to get my setup producing some substantial results.

Hey foggy,what was the unit made from you used on your Hyundy and how much gas output per min did it have. You guys got me making these things now ,but havent got enough output yet.Any info will be helpful................Garthr what was the best out put of your 2 put together? Cheers

It was made from a Nescafe jar and some stainless flat strap I had hanging around. Gas output was probabky only 250ml/min but it did help a 1.5 hyundai abit. I wasnt running an effie which made the gain rather small. The next version I use on my AU I hope to get a mate to program up a PIC for me so I can vary the gas output based on an rpm input.

Just stumbled on this link, http://www.antique-engines.com/stainless-steel-electrodes.htm.

For the uninitiated, the by-product is Hexavalent Chromium (http://en.wikipedia.org/wiki/Hexavalent_chromium), which was the toxic substance that Erin Brockovich based her case on.

The dangers of this substance in water is well known, but I'm quite sure we're all responsible enough to not pour used solutions down the drain in the off-chance the solutions themselves (be-it KOH or baking soda) would leech the chromium out of the stainless steel electrodes.

I'm going to do a bit more research on whether the electrolyte solutions react with the s/steel to produce the by-product and would welcome discussion from others here on their understanding and findings too.

I think your quote got mangled in my statement somewhere there, Noel. I know from viewing countless HHO vids using all sorts of solutions are working. I think caustic soda has been banned as a drain cleaner now, so we shouldn't willy-nilly be pouring excess or waste solution down the gurgler. However, in my previous post, I just need to check if s/steel will leech out the Hexavalent Chromium into solution, and if it will do so whether pure water, KOH, baking soda, or even distilled vinegar would cause it to leech out.

I guess what it means for all here is that we treat it with the respect it deserves.

Righto, been doing a bit of surfing and stumbled on the following:

Check out Zero-Fossil-Fuel's recent Youtube video, http://www.youtube.com/watch?v=pxWQZJw5RnQ where he points out the dangers of Hexavalent Chromium in the electrolyte solution, and reinforces care about waste product disposal.

He does mention KOH and sodium chloride (salt). No idea about baking soda though.

One of ZFF's respondents has a few tutorials about HHO safety.
