Well after talking with some MFI experts, it looks like what I want to do is not actually a true MFI system.
I would use a few MFI parts, and a few EFI parts. Turns out MFI works based on a return system.
What I would have is basically a big boost referenced alky kit when it's all said and done... Instead of a barrell valve it would have a boost referenced fuel pressure regulator with an electronic fuel shot off valve that would control when the methanol is released into the engine.
The fuel shut off valve would stay in the closed position while the gasoline injectors are running, and then would open at a preset PSI, and the fuel flow would be varied by the fuel pressure regulator like it does on the stock system.
It would basically go from the fuel cell to the pump, then to a Fuel pressure regulator, then to the shut off valve, then to the fuel distribution block and the injectors/nozzles. The fuel pressure regulator is what would control the amount of fuel the system puts out. It works on the same principals as MFI, but since it is for WOT only it is a much simpler system than a full MFI setup.
Got a lot of research to do on it, because this is only a theoretical design right now. Got to see what's out there and what has been done. The real reason Im thinking so hard on this is the fact that I am about to start putting together an LSX based turbo Texas mile Fbody. MFI and land speed racing go hand in hand, but if I can test the ideas on the GN then converting it to the race car will be no big deal!
