Hardcore Crazies : Hydrogen Fuel Injection
Anyone in C5 Tech investigated using Hydrogen Fuel Injection yet?

Not to be confused with replacing 93 Premium gasoline as my primary fuel - this is as an octane booster for my supercharged application...
Seriously considering this mod - only draws 20 amps, the same as your headlights...
And Yup - you know it... I am definitely not mentally stable

A small amount of hydrogen added to the intake air-fuel charge increases the octane rating of the combined fuel charge and enhances the flame velocity, thus permitting the engine to operate with more advanced ignition timing, a higher compression ratio, and a leaner air-to-fuel mixture than otherwise possible.
The result is lower pollution with more power and increased efficiency. Some HFI systems use an on board electrolyzer to generate the hydrogen used. A small tank of pressurized hydrogen can also be used, but this method necessitates refilling.

That would be sweet!
Fill-er up with water and premium please! I know a lot of people who go FI use water/meth injection but that seems like it would be way better.

Its just a matter of time before I play with this. It is not a scam, its real. There are many other manufacturers as well as small time hobbyists selling kits. Others even publish their kits online for anyone to build. All ya need is some wires, stainless steel plates, a cannister that can hold a small amount of pressure, some fittings and some hoses.
I don't know if my Vette will be what I try it out on though - not because of fear or damage - just because it would be easier to retrofit into an old beater with more engine compartment space. Ideally, I want to find an old 4-banger to play around with.
The hydrogen produced by these units is significant. Not enough to completely run a 5.7 litre engine though.
What I find attractive is not necessarily the power boost or gas mileage increase, but the cleaning of the combustion chamber. This happens not just because hydrogen is cleaner burning, but minute amounts of water molecules either make their way into the combustion chamber, or are produced as a result of the combustion. The result is a cooler and cleaner running engine.
Another reason for not wanting to try this out on the Vette has to do with metering and the fact that the Vette is fuel injected. A carbureted engine would be much easier to setup. It is easier to configure a throttling setup than with injection. These units don't meter - rather they dump a steady stream right into the intake path. Low throttle conditions will be affected far more than WOT throttle conditions.
Hydrogen has 3 times the energy per weight as gasoline, but that's not the real advantage here. Hydrogen is far more accepting of a wide degree of AFR ratios, as opposed to gasoline which gets real picky in ICEs.

I'm going to use this purely boost referenced via the MAP. It will not be on all the time and it will be finely controlled.

I have looked into some of these hydrogen engines.
there are some disadvantages. ex. embrittlement
The embrittlement of of metal or alloy by atomic hydrogen involves the ingress of hydrogen into a component, an event that can seriously reduce the ductility and load-bearing capacity, cause cracking and catastrophic brittle failures at stresses below the yield stress of susceptible materials.

At the minute quantities of hydrogen introduced, metal fatigue is a non-issue.
Again, I am not talking about hydrogen as a primary fuel source - only as a boost-referenced octane booster.
