me again, just thought i would give an update. yesterday i installed a dc to ac converter and a aquarium pump to help push the hho into the turbo. the pump is variable adjusted to control the flow of air. the two jars are bubbling like crazy with no where to go except in the engine. i have also capped off the check valve to make sure there is no leakage. it has been extremely windy here in Texas for some time and will be for the forseeable future, so im not sure when i will be able to do an accurate test of mpg. test results will be posted asap.
