OK....some help....i have a bit of info that may help...i have been in contact with some one frome HIMAC where they research high mileage....so i get first hand info on whats best to do and if i have questions i can ask him...."if you raise compression then you produce more nitrousoxides that is a bad pollution that is why they kept compression down"...thats straight from him...u can raise compression with it....but even without the hydrogen u produce more nitrousoxides by raising compression....so if u are already using a higher compression and passing air inspection then u will be fine with the hydrogen.....i dont think there would be a problem with detonation unless the problem was already existant....hydrogen mixes with carbon...the residue thats left from a gasoline burn....and creates water....thats not really a whole lot of water at one time but i think it would work sorta like water injection to a point to make up for the extra burn of the gas mixture...on carburated engines there is no airflow sensor so it doesnt effect that one bit....only on fuel injected engines will it effect anything...i havent looked into a system for fuel injected vehicles but i hear they are a bit more complex....dont bother hooking up the hydrogen to the air filter...it would be better to insert a tee in the PCV hose and share it through that...also dont use a pump since there arent too many that can handle being run dry for any length of time...the plans on the website are from when the guy started and hasnt updated obviously...although bruce at HIMAC keeps me up to date....it is true that the electrodes need to be replaced after 1-2 tanks...but if a tank lasts 2-3 times longer who really cares...it'll cost about $3.00 and 1/2 hour of time max to replace the electrodes and watever else it costs to replace the water/electrolyte mixture....retarding the engine is necessary because with the hydrogen the mixture ignites earlier therefore u need to retard the timing...the carb actually doesnt need to be leaned out....the 300% increase came from use with the pcv gas condensor as well as the hydrogen...hydrogen alone only increases gas mileage about 50%...the pcv also increases about that...mixed together creates a natural gas to further increase mileage...most of the gas that goes into your engine is unburned fuel...doing these projects gives u a very high incresed fuel burn which results in more power and better fuel efficiency....you wont notice the mileage gains so much if u drive lead foot all the time...but no-one does that....hig compressions need high octane fuel period...the hydrogen really wouldnt effect that...in fact it may help...there is no need to rejet to notice increase in mileage...just drive proper....i notice quite the increase in mileage just with my pcv gas condensor...i havent got the hydrogen thing made completely yet...i want to do it right so it's taking some time...the next bit will be about the progress i have gotten with my first bunch of experiments......
dad went on a trip a bit longer than 200 km with my car and came back and used a bit less than 1/4 tank...that was with the PCV jar....i had a mixture of cheap oil and tranny fluid in it at the time....he said he maintained a highway speed of about 120 km/h
next day i put 2 quarts of premium oil in...that rendered my pcv unit useless since it requires the cracking of oil to fuel to work....cheap oil cracks...premium oils have additives to prevent the seperation of the fuel....i went 75-80 km on 1/4 tank...highway speed was about 150 km/h...part of the big loss in mileage was from higher speeds but also due to the oil change....
day after that i had my hydroboost first built....drove 120 km on 1/4 tank...highway speed varied from 120-140 km/h...that was my very first test with the hydrogen system...i am positive that it will be better after my next rebuild...
since then i havent tested anything...just changed my oil to some real cheap stuff...so thats all ready...my hydroboost is almost complete...may take about a week to complete....when the 2 units work together i should see great mileage gains....my firs t hydrogen setup was quickly put together...just 2 electrodes (threaded pipe) and a hole in the lid to keep the jar from imploding....water was tap water and i used epsom salts for the electrolyte....the next setup will be a bit more complex...i might use a thermactor pump to feed air into the jar and use a valve to even out the pressure difference between the intake vacuum and the thermactor pump pressure....also i have electrodes with plates on them as the diagram shows....the water will be diluted waterwith possibly rubbing alchohol and viniger as the electrolyte....i am happy with the results i am getting though....and if u find that the hydro boost isnt doing anthing then its not built right or the water/electrolyte is wrong...if u need more info i will be glad to help...also if i dont know it i can email bruce....hope i covered enough...take care...glad your interested ...i get quite excited about this project...although i have had it almost long enough to just consider it a normal part of my engine now...lol...
