yeah Im still not convinced fuel sharing a common rail at WOT is a good idea, i know fuel travels pretty damn fast under the pressure its at, so as these solenoids switch, one fuel will push the other out very quickly. But in saying that, I imagine you could gain a few thousand revs at least, in the time this took to happen..Even a momentry hiccup could be detrimental..really you would want some sort of octane sensor in the rail to be safe..
However a twin rail system each with its own dedicated tank/lines that switches to secondary injectors and maps at desired point I think would be much safer.
Although it is somewhat more complex in design it would be much simpler in setup and usage..
I'm thinking I would just have the secondary tank setup with an arming switch as well so it wasnt always primed on start, gives you a safety net for rainy days etc...or if the tank runs empty before your primary tank.
I'm actually quite warming to this^^^ idea .. though with 2 e85 outlets within a km of my house I know which path I'll be taking
