Hi! This is my first post, I have tried to learn as much as I could from lurking haha. I have recently embarked on building an HHO generating cell. I have had no problems constructing the cell itself, but I have not done any tests yet.
My question is, without any modification to the ECU or MAP/MAF sensor, could I damage the engine of my car purely by including the HHO into the intake manifold? It is a 1991 Kia Sportage. Right now I only have one 7 plate cell, and would really only like to hook everything up for tests, see if I can get any gains without any ECU/O2 Sensor/MAP/MAF tweaking.
So, in closing, could a plain jane HHO generator hooked up to a manifold (with backfire arrestors and bubblers of course) damage the engine itself? If so, what should I look out for?
Thank you!
