I switched the hydrogen generator from the 6cyl GMC Sierra to my Suzuki Baleno year 2000 engine:4 cylinder 1.8 liters. This is a TEMPORARY setup just for pwm testing and for experimenting with different electrolytes.
I was getting about 500ml per minute with 15 amps
*will be testing soon after i replace the wiring I am using house wire and i will be replacing it all with high grade automotive cable.*
