200 ci inline six on E85

[primal1]

what would it take to make this happen.

 

[ludwig]

E85 gas pump; nozzle in filler port; pull trigger; release trigger when full.

In addition to Ludwig's inputs, you'll need to at the very minimum, increase the jet size to handle approximately 30% more fuel.

8) and once you have converted a carbed car to E85, you cant switch back without having an excessively rich fuel mixture. that said, if you convert to a megasquirt EFI you have the option of adding a flexfuel sensor to the system that will allow flexfueling.

Hot Rod (IIRC) did an article on how to switch to E85. it was really simple

 

[spartman]

You could either bump the compression to 12:1 to run E85 efficiently, or go gonzo and put a turbo on.

If you make the switch to the higher compression you will not be able to run pump gas anymore.

Just some things to think about.

You guys are talking about optimizing the fuel characteristics. That is a completely different issue than "E85" as it is currently talked about. I am well aware that there are special modifications to burn the fuel efficiently. My flip and superficial comments were based on the current concept of just putting the stuff in and eating the 15 to 20% loss in performance which comes from the less efficient fuel, which is what most people will probably do. And then think they are doing something to save the planet.

This political stuff has nothing to do with either performance or economy. If it was, we would have true flex-fuel vehicles like the kind that are already available in Europe and we wouldn't pay farmers to burn food for profit.

actually, i started this thread to get an idea on how to rebuild an engine to burn e85 most efficiently. i did a search and came up with older threads with guesses. i was hoping to that in the last year or so, it has became more of a science. as soon as i get moved into my new house (i finally get to have a garage) and get settled, i am going to start build a 200ci to drop into my 62 comet.

is this available to read online or do i need to get a back issue?

will i need to increase the jet along with higher the higher compression?

Yes. E85 is, of course, 85% alcohol which has something like 30% less energy per gallon. This means that you will need to burn more fuel to get the same amount of power, thus the need for bigger jets.

The nice thing about E85 is the higher octane rating so you can run higher compression which will gain back some of the lost fuel economy.

I think it's a good idea. Go for it!

Im for E85 if for no other reason to tell OPEC to go stuff their $90 a barrel and rising oil prices and free the US from dependence on foreign oil.

 

[primal1]

is 12 to 1 the right compression for e85. that is quite of decking even with flat top 2.3 pistons , is'nt?

 

[spartman]

From what I understand that is the recommended minimum for E85.

I plan on using some Keith Black Hyper pistons from a 302.

They will have a -14cc dome and will push the static compression to just under 12.

The kb part number is KB365

here is the link to the piston itself: http://www.kb-silvolite.com/performance ... ls&P_id=97

HTH.

 

[fast64ranchero]

Spartman Your not planning on running those pistons in a log head six are you? if so your gonna have a hard time getting the rings to seal, look at 255 V8, or 2.3 Tempo pistons

 

[spartman]

This would be for my 240 six.

I was told that 302 pistons are what to use in this engine.

Is there something I am missing?

Your thread title says 200 six, so you are confusing everyone.

 

[spartman]

This isnt my thread.

Sorry for any confusion, I was just attempting to show what I was going to use in mine for a comparison.

Once again sorry about any confusion I may have introduced.

 

[wallaka]

Didn't notice that! Anyhow, you didn't specify. No harm, no foul.

 

[Crosley]

Are current gaskets and O-ring materials in a carb application able to handle the E85 fuel without a problem like swelling , leakage, drying out?
