How much compression ratio will E85 support? How large a fuel cell do you streeters have in the trunk??

Fwiw, I've ran many 10-1 static CR LS engines at 25-30psi boost on E85.

20 gallon cell. Have flirted with 17 lbs. without problems other than traction. How many mile do you get out of a 20 gallon cell with normal occasional street beatings I'm swaying and wondering why I have been to thick headed............

Really I think the chart is more of a general guideline as it isn't just manifold pressure vs static compression ratio that comes into play, there are a ton of other important variables.
You could have a few differences just comparing 2 turbo combinations to say the chart can't reflect all turbo combinations the same.

Only really checked once. Got 11-12 m.p.g. just driving normal highway speeds with minimal" spirited" (a.k.a. wife on board) driving. This was carbureted on 470 c.i. 9.9:1 compression ratio by the way.

I would run E85 in a heart beat if we could get it here.

My current bracket motor(400 block stroked 4.300 with 4.375 bore) has right at 15.0 to 1 compression, ran it all last year on the local pump E85 that checks to be between E86 up to E89 % depending on which jug it came out of and how long I had that fuel sitting in the jugs I have five 5.5 gallon plastic fuel jugs, some had fuel left ln them form the year before I bought 8 gallons of E98 from Wal Mart late last year and I'm going to try and mix it with my local pump E85 so I get E89 or E90 all the time I'm hoping that by having the same ratio percentage I can get a good handle on the tune up and make it go as fast as I can

I don't see myself needing more than 15 lbs of boost and maybe 10 lbs to reach my legal cert. Pro Systems is providing a "booster" for my carbs to improve my lean spike at the hit condition.If it does the job I will be gold,,,,,,,,if not I need to be E85 THUMPED!! The legal limit is 8,50 so I'm a little over a 1/2 second away
