ttoyoda, It seems that you are correct in your assumptions. In practice, I don't know how exactly it would all work out. The removal of the throttle body is possible because of the huge range of air concentrations in which hydrogen can burn. Gasoline is quite narrow. The full DVD goes into alot of this.
There are also some big drawbacks to a full h2 (or h2 hybrid) conversion because h2 is still hard to come by. Unless you have a solar hydrogen generator in your backyard or access to h2 filling station it is hard to justify all the work. That is why I want to do an h2 assist setup because it can be changed to run on 100% gasoline very easily.
