2009 Chevy HHR

[thumaj]

I just built and installed a new HHO generator for my Chevy HHR. I hooked a vacuum line in to the air cleaner duct but it seems like it is not getting any HHO. I am not sure what to do for there is not a vacuum to hook it to.
Can any one help?
Thanks

just install the HHO line into the air intake hose as close as you can to the butterfly valve, you will get HHO into the motor that way, when the car is running it is sucking air into the motor so if you put it into the air intake hose it will take the hho along with the air.

I installed one line into the air cleaner and one vacuum line next to the butterfly next to the electronic controlled throttle.
I cannot tell if it is working or not, the fuel mileage is no deferent, the performance is the same. I can see the gas bubbling up in the jar and that is all.
Not sure but think it is working.

im sure it is but you will need some kind of components to control the sensors to get good gains like EFIE, MAP/MAF sensor enhancer, or a controler for all of them like my ECU genie, it controls 2 o2 sensors, the ect sensor, the iat sensor and the maf/map sensor. i get pretty good gains, you can see my car here in the forum show off your ride, it is the post that says ill be first.
