E85 Carbs

[KB Camaro]

Does anyone have experience running one? Any opinions, my biggest concern is that it would not be a "flexfuel" car that can adjust timing if you get a tank of E50 during the winter months when the blend is slightly different. Anyone have any other concerns/thoughts?

Are you looking at Quick-Fuel? Just remember you'll require 25%-30% more flow, so larger fuel lines and a healthy fuel pump will be required. You'll also want to have fuel lines and a tank that's suitable for E85

here's some more info, I looked into it when building my 408ci LS but decided to keep it to 93 pump gas

Biggest issue is the E85 fuel minimum spec is 51% ethanol rather than old spec of 70%. Now best way would be to find an adjustable FI set up. always wondered how well a FiTech would handle different ethanol content.

If anyone looks into this, Innovate makes a combined “ethanol content” and “wideband gauge”.

An E85 carb can be tuned very well with this type of tool.
