HHO Systems
Anyone running an HHO system? I'm a DYI kinda buy. I've been running WVO or the past 12 yrs in my MBs cars. I have a '69 Chevy C20 with a Perkins straight 6 with 388 Ci on diesel with a water injection system (WIS). Looking at the advantages of increasing the mpg by adding a HHO system.
