Well, I'm coming out of left field here, so here goes! The main reason I'm looking into this Injection
setup is to be able to use E-85 in my BB. Alcohol has always been a superrior fuel to gasoline
because it makes lots of HP, runs cooler, and now that we have an "easy" way to meter it,
I think I like it! Hope it gets better and better, and hell yeah, I think there will be a day coming
when gasoline as we know it goes away. The more accurately we are able to supply an engine
with air and fuel throughout the RPM range and at varying loads, the more efficient the engine
becomes and we can squeeze out all of the performance.
Although E85 has a higher octane level than straight gasoline, it has much lower btu rating, which means it must be consumed by the engine at much greater rate. Requiring a larger fuel delivery system, larger injectors, everything in the fuel system must be alcohol compatible, and on top of that it burns at a different stoich rate than gasoline. The air fuel ratio is different. The OE's have it figured out, E85 can be mixed in to the fuel tank and the engine computer can sort it out. I have not seen an aftermarket system that can do that. It would require some type of sensor in the fuel system to determine the alcohol content.
Do you intend to run strictly E85?
