I just installed a Gen setup in my fathers 94 GMC Sierra 2500 Truck.
went smooth , installed 2 gens in series ,6 volts each. for those that dont know series means
+ to Gen1 out to jumper to Gen2 out to - (the water conducts the current to the other cell and halves the voltage to each gen)
truck has been a very good truck and ran great before.
94 GMC Sierra 2500 5.7L auto , 225000 miles
normally 9/14 city hiway mpg (was killing my father)
new spark plugs just installed
truck has throttle body injection (2 large fuel injectors on top of a carburetor looking like intake on top of manifold) injected HHO right on top of this clean side of the air cleaner lid right over the fuel injectors.
2 gens - 4 large 8x4 inch 16 gauge 304 stainless plates spaced about 1/8 inch apart
with NaOH electrolyte 2 teaspoons per gen . +-+-
30 amp relay wired from battery next to it and activated by a toggle switch inside cab only powered when truck is on.
1 HHO hose running from back of truck to engine compart with 1 copper tubbing pipe run over driver side exhaust , then going up into the air cleaner, 5/16 inch inside dia clear hose used.
1 one way low force to open check valve installed right before copper tubbing to keep HHO filled in the lines at brief stops. (doesnt need to create all the HHO gas again to reach the front of the truck from the truck bed that way ,, its up and producing very quick at a start)
adjustable knob type efie controller installed in the cab to control the 1 o2 sensor pre cat. running around 380 mv right now seems good. 400 was a bit too high started hesitating.
I havent checked the output but a water bubble test up front near intake shows very good HHO production.
heres a few pics will post more soon and keep updated on MPG gains .
cheers , Craig in hot ca. 107 degrees.. uuuugh. was totally worth it though as its a nice gift for my dads 73 rd Birthday
UPDATE - 8-31
my Dad called me tonight . he took a trip up to the mountains , normally his truck got 9/14 city hiway , today ... 23 mpg combined mountain hiway! woooohooo i like it .. will keep you posted
UPDATE - 9-13
the acrylic gen cases didnt hold up .. they started cracking , I was worried about them holding up.
so i am thinking now to use one 5 gallon paint bucket with a sealable lid . attached a pic of the 5 gallon bucket design sketch below. my father will try this , will keep you posted. the thing on this design is it doesnt get that hot. so plastic should be ok , and of course there not alot of pressure so a 5 gallon bucket with a sealed center divider to make 2 cells , with sealable lid this should work. the good thing is he was getting good results so we know this does work .. its just getting some good gen cases going. will keep you posted.
