- Switching to E85 would mean running out of fuel pump sooner than 93 octane when adding FI, correct?
- Would E85 help in any way to extend the power ceiling many have faced with the stock pistons (I think the consensus is 650whp)?

Thanks for any insights you have. Good luck with your build.

-flex fuel - I have never heard anyone at GM officially talk about why they have not embraced the flex fuel sensors. I just know they have not.

- GirlyNFG says in post 3 on this link that he is tuned for E85. He has the most powerful dyno on stock bottom that I know of.. (has upgraded to LT4 mechanical pump). http://www.camaro6.com/forums/showthread.php?t=462746

- yes, if your car is tuned for E85 it will increase the workload on the fuel pump and fuel pump limitations will be reached much sooner. You just need to upgrade the fuel pumps to make the power.

- This is a really good question on the pistons. Some testing would have to be done to know for sure but my first thought is that you could probably make a little more power on the E85 without piston damage because combustion temperatures are lower with alcohol. Heat is usually a factor in most piston failures.
