According to a article in the latest Drag racing action mag there is a tester offered by Quick Fuel that will test the Ethanol content of your fuel, might be somthing to look into and it look's to be a decent article,,,guess I need to sit down and do some reading. now I need to try and find a station around these part's that sell's it.

---

Bill do you have any info or P/N on that tester
or the article that you can post. I might have to see
if I can get that mag

I have been happy with this method from the E85 handbook on the National Ethanol Vehicle Coalition website:

Procedure for Testing Hydrocarbon Percent of Ethanol Fuel Samples
Based on SAE International Paper 912421 (Prepared by NEVC)
Equipment for E85 testing
VWR Scientific phone # 800-932-5000
50 mL pipettes; Cat. # 52966-217 pack of 12/$212.18
Safety Bulb; Cat. # 53497-202 pack of 3/$18.45
100 mL cylinders; Cat. # 24762-117 pack of 4/$120
Procedure
• Using the suction bulb, pipette exactly 50 mL of fuel sample into the graduated cylinder.
• Add about 48 mL of water to make the total liquid volume just less than 100 mL.
• Place the stopper in the cylinder and shake vigorously for about 15 seconds.
• Carefully loosen the stopper to release any accumulated pressure; do not remove the stopper.
• Close the stopper again and place the cylinder upright on a level surface. Allow the mixture to sit for about
15 minutes.
• Record the total volume of liquid by reading the lowest part of the upper meniscus (the curved interface
between the liquid and air).
• Record the total volume of the alcohol/water layer by reading the lowest part of the lower meniscus (the
curved interface between the two liquid layers).
Calculation
• The hydrocarbon percent is calculated by: 2.1 + 1.94 * (total volume - alcohol/water volume)
• Assuming the sample was an ethanol/hydrocarbon mixture, the ethanol percent is 100 minus the
hydrocarbon percent.

Example:

Upper 98 ml, lower 91 ml
2.1 + 1.94 x (98 - 91) = 15.68
ethanol = 100 - 15.68 = 84.3%

Jim, thats the same as I use to do when I was working,
same procedure. I was wondering if they came out
with some thing new

My Mallory pump locked up after E85 use,but I bought it used about 4 years ago,and it didnt act right when I pumped the cell dry for the switch over. I assumed my Battery was low, after runnung the last race and sitting a few weeks It wont even turn. Mallory has alcohol gasket rebuild kits for the pumps and regulators and offers a rebuild service.I think the paper filters may be prone to failures as well so I deliberately left it fueled as a test.

I'm running a pair of Holley black 150's and so far
they've been fine

I just found out today that there is finally an E85 pump within 15 minutes of my house!

It is $2.89 today.

---

I paid $1.23 here last week....

---

Its amazing and confusing why there is such a difference in price around the country. I checked on it while I was out today, its $2.49 gal here. I thought it had kinda been keeping pace with gas, but I guess not. For those paying $1.23 what is reg unleaded, and those paying $2.89, whats reg there? Reg here is $1.34.

At 2.89 thats real pricey, around here its about
1.65 for E-85 and about 1.50 for regular. If your
pump can handle the increase in volume by 30% all
you would need to do is the carb. I have a spare
1050 that if I ran out of E-85 I can switch the carb
and be running on race gas(buy it at the track) and
be running in 5 minutes by just changing the carb
and backing the timing down a few degrees and be
running the same times(what I've seen so far)

Quote:

---

hey P body, I can't remember did you pick up some when you switched?

---

Actually I stayed the same BUT I didnt touch the
timing yet, I was going to start bumping it up
but I put the car away early this year. I do mean
it stayed the same within .01, best before was 9.08
and with the E-85 it was 9.09 3 passes in a row

Here's another question, there's alot of deals out there right now on alcohol carbs. What's it take to run E85 with an alcohol carb?

---

Well its starting out with the good parts but I
would think you would still be working it over just
the same as going from gas to E-85 when it comes
to the passages and jetting but that MIGHT be a
good way to start if it isnt all corroded

Quote:

---

Oh ok, I thought I'd read here several times that alcohol carbs were pretty close to an E85 carb.
I think the best bet is an E85 carb from someone like Quickfuel.
I'm just worried about getting a batch of E70 instead of E85 from the pump.

---

This is something that we all look at, but if you
check the drop sheets before you buy your fuel you
would have a pretty decent idea what your getting.
Of course you check it and if its what you want then
buy it in quanity(drums) instead of just a tank at a
time. Check with Quick Fuel like you said about the
differences between the 2 style carbs

Jim, I have been following the discussion on the E85 forum. It seems to me that Drag Chevette has a pretty firm grasp of what needs to be modified to make a carb work on E85. Would that be your opinion as well? I'm considering having him modify my 950 is the reason I ask. Jim

---

Yes I believe he has about as much info as anyone
and he did a fair amount of testing to get where he is.
I would let him or just use his info and do it yourself
