Info on George Wiseman books

[cjsride]

Has anyone read them? I own 2 late model ( 2002 V-8 and 2006 V-6 ) vehicles and not sure if the info is aimed more at carbureted vehicles.

Also they talk about a simple water injection system that can be put together for less than $5. Does anyone have details on this? Wondering if its something like is shown here - http://www.water4gas.com/members/zpe/Auto.pdf

Thanks.
