Default E85?

Any body know where I can find resources on converting my BBC to E85? I'm looking at going forced induction and I want the benefits of higher octane without the price of race fuel. I've done a few searches on-line and can't find much. I appreciate your help!

There'* very little information on it. I looked earlier this year. But ended the project because there'* only 3 stations with 30 miles of me.

A few things you will need is tuning software. Because your going to need larger injectors. 25% larger just to match what you have right now. Now add in going forced induction your going to need larger injectors still. You will need 42.5# injectors to keep you in the stock area. 69# injectors if your going supercharged. And possibly larger if your going to go crazy turbo size. Other then your changes in injector size, it'* just working on your AFR that will be needed. I'm not sure, but your injector Orings should be OK, but you may want to check on that. E85 is hard on some rubber Orings.

Ya, I found a site that makes E85 ready carbs. There is 2 stations within about 15 miles of me. We'll see. I'm still doing the research.

What kind of engine and year are we talking about here? You mention a carburetor. For that your talking about changing the jets. What ever it is your doing it'* a project I'm very interested in following. Please be sure to start up a thread in performance. There are others that have looked in to E85 as well, but most really don't move forward. I would do it if I actually had a station near my house.

From what I understand from guys who have done it is this:
You have to let your engine "warm up" 10 - 15 mins all year round (yes, summer too) to let the ethanol start atomizing right before driving.
You have to revert back to regular gas and have a gas tune in the winter time.

^^^ The above is true. It takes some clever tuning to get e85 to cold start and idle well. And an entire different tune to get it to run in the winter months.
