Ive been looking into this whole hho thing for a while now. and ive decided im going to give it all i got. lol. one thing that has got me. if you put it on a naturally aspirated motor then the motor will suck it in pretty much. but i have a turbo charged motor and being that there will be a positive pressure in the intake and not a negative how do you go about doing this. Ive thought of pumps and such but im open for ideas. Ive noticed that Stratous has a cummins with it. how did you do it. thank you all for your help and time. im new on this site..... thanx again
