Sorry - I went MIA after posting this. Thanks for all the replies as lots of good information was shared.

I'm not sure I buy into the notion that a higher flowing fuel pump along with larger injectors are truly required. I understand the need for larger injectors, but it seems as though the fuel pump has enough headroom to cope with the additional flow. I loosely base this on the fact that many of the forced induction systems out there use upgraded injectors while utilizing the stock pump with great success.

So regardless of the fueling system capabilities and despite the obvious performance benefits of E85, I still haven't heard anything that would convince me to run it in my car just yet.
