This spring I am going to begin experimenting with E85 in my 69 Camaro. Currently I am running a BB454 with electromotive-inc's multi port fuel system with DIS ignition. With this setup I can control all fuel and ignition mapping and many other features.

Considering the fact that it has been done regularly and that E85 has a octane rating of 100-105 depending on who's your buying this will be a good fit for me since I need at least 100 now for my car to run. So....93 octane + octane boost usually ends up being 5 bucks or more a gallon when I fill up.

Sourcing information has been easy, sourcing factual and correct info will be not as easy but doable.

and of course a million more sites to be found. I'm doing this for two reasons. The benifits of cheaper fuel for my Camaro and possibly my Apache which I may also do and also because a large amount members of a different forum I am on concerning hybrids don't considered a flex fuel vehicle as any type of hybrid. Even though it is a "hybrid fuel" or alternative source it doesn't rate with them. I'm all ready disliked I imagine because of my muscle cars and SUV's but oh well. Dad said I could be anything I want when I grow up so I decided to be a *&^hole.

If anyone else has gone this path I would appreciate any information your advice you have on the subject. Once the spring thaw comes I'll begin my experimenting and report my results if anyone is interested.

I am well aware of the potential pitfalls to my vehicles running E85 in my car. My fuel lines are first on the list to be changed. I need a new tank anyway so a good clean steel tank is to be installed. Fuel filters are easy to come by and then I will look into a different fuel pressure regulator and injectors. I may start experimenting without changing everything, but we will see. I have a few months to research so time is no issue.

Summer can't come soon enough, -10 today, 40mph winds and snow on the horizon. Dang it, I spent yesterday sitting in the garage just staring at the toys.

 

Looks like you've done your homework to me. I'll be waiting for updates once you start running the stuff.

 

Some news. After contacting my supplier of the fuel system (electromotive-inc.) they said i was good to go.

Did some small changes to a few fittings and the filters and ran some half E85 and half gas and didn't notice anything different.

Went to a full E85 load with a tweak to the fuel trims, %30 more fuel, a little more advance and could feel a difference. Next step is to get a G-force meter and do some measuring with gas vs. E85 in eachs fuel setups and see what happens. So far the biggest change is the price of fuel. Mileage.....I don't care about no stinking mileage Actually, haven't noticed much of a change. 10-13mpg with each, but my foot is always in it so worrying about fuel mileage is out the window.
