unscientific jet test below! Does anyone have back to back runs and dyno info on E fuel blends verses non blends and do the E10 blends like Sunoco 94 like more jet and timing!! Thanks   did some searches but did not find exactly what I was looking for but maybe now guys have more experience??

wonder what jetting achieves this??
The standard reply "It depends..." is the only true answer to that question.

I more meant if X jetting in the test with 0 Ethanol and how much he ended up going in jets sizes with 10% as in 1 or 2 jet sizes in this case!

read the article does not really tell what jet changes from a 0% ethanol fuel to a 10 % ethanol fuel?? Did find this on line that says: "E-10 -lower float levels 1/32 from original specifications increase main metering circuits’ fuel flow by 10 percent, increase idle jet diameter by 0.002 inch." so does that equates to about 3 jet sizes  supposedly According to Holley, each jets size is just over 3% source http://www.thecarburetorshop.com/Ethanoluse.htm

Well when we check my plugs two weeks ago they were real white and clean. so when I went to jet up Friday I found I actually had the stock jets in (92 square) instead of the 94's I had run in the cold last fall forgot when after last time out i had ignition problem which turned out to be failing coil I had put the stock for my old dommy back in. I wanted to go 95 square but only had 2 95's so i went 94/95 front and 95/94 back. First 4 TT's for 1/8 mile pro tree racing going in much deeper than normal 1/8 mph were 102 into a cross wind where last week similar air were 101 ran clean and smooth plugs now have just a slight darkness to them so think I'm on the right track. Now to test the 94 I ran to see what the actual Ethanol % is?

In the heat you have to let it vent... you MIGHT be able to find a 1 psi pop off valve so it will relieve pressure above 1 psi... but I dont know of any

Funny you should mention that. :-0) part of what got me going was the 10% in the US threads and wondering if Sunoco is in fact 10% as I did find on line and verified with a test. Then how to take ethanol out of the gas for you lawn mowers (and snow blowers up hear) then my machinist was telling me about a roundy round guy we know running a 347 ford who made the most power on a dyno with Shell V91 even over 94 Sunoco (20 hp and 30 or some other fuel brands) just doing fuel changes and running again. I'm going to buy some shell 91 and test it for ethanol as looking for fuel for the lawn mower at the very least. But at 11.75 to 1 and maybe a true 12 to 1 with my aluminum rod growth hot not sure I want to try 91. If I do it will be a TT day and start my timing at say 34 and sneak it back up to 39?? Now on line searches dated 2012 turned up Esso 91 is supposed to be ethanol free, I seen a returned inquiry to sunoco (so Husky and Petro can) saying 91 is also ethanol free but only way to guaranty you get ethanol free is to buy from stations that don't sell ultra 94?? apparently 94 is 91 with 10% ethanol added which brings the octane from 91 to 94?? will be checking! I think the shell is supposed to have some special New Nitrogen Enriched ??  Today I tested 87 from Petro canada and it's 8% Ethanol

I tried finding the post on the OSCA message board, but I asked a question on there about gasoline, and Nick Agostino (im sure you know him, runs the twin turbo camaro now in outlaw 10.5) who builds gas stations had told me that all gasoline in Canada HAS to have 5% ethanol in it as legislated by the government. Now, I have never tested the gasoline from shell or esso, but if he is right (and id like to think he is since he builds the damn places) then I would assume those fuels contain ethanol as well, even if in smaller amounts.
Only way to find out though is to test like you are and see

Your taking a number as GOD... as you said that the so
called 91 made more power... it may have on that
set up.. over octane WILL make less power per the
same timing.... its not rocket science but it does
take testing

Actually, I said that the only way to really know the ethanol levels and see which will make more power is through testing
I myself have personally never done any tests to see.

Its always a bit scary to drop the octane but I've
done it on 2 engines and went quicker on the track
without issues... MOST people tend to over octane
to be safe and just call it good
I have always been the type of guy you mentioned in the latter...but this post has me thinking about possibly trying out the fuels back to back and seeing if there is a difference

Thanks keith like I said a freind who runs in the lower Nascar Canada ranks has tested and got best so far fom Shell V Power. supposed to be ethanol free. Anyway the law As I understand it in ontario and I think canada right now is there has to be an average content of 5% ethanol in the total fuel sold by any one company. Going out now to but some Shell V power and testing it for Ethanol and maybe some Esso 91 while I'm out!
