N.d.r.a. Crates=no e85 fuel@ fms

Friendship speedway will not be letting the crates run e 85 fuel....

This was up to the owner not me or ndra....

SOME FOOD FOR THOUGHT.....


E-85 Fuel Test on SuperFlow ChassisDyno
Just to let y’all know we ran about 60 dyno pulls today and completed our first round of E-85 testing along with our new in house blends. Our baseline fuel was our own blend of PCD Power 110 that we have developed on for crates on pave. It is pretty close to MS-109 and almost identical to Late Model Plus.

Our base test was with one of our 650 ASA Gauge legal crate carbs and the trusty old 604 mule. Air stayed the same all day within ½%. None of the numbers are corrected, as I prefer the data to remain uncorrected within the day I am running. If there are major swings in the weather data that is recorded in the notes.

I feel that the conditions of the day are what you would have at the track and I don’t want my machine to add power to my sheets if the weather gets worse.

1. PCD Power 110 ( $8gal ) was the baseline and it hit 434RWHP

2. E-85 First run with no changes to the carb was 386RWHP ( was lean as expected ) . Following 3 runs backed-up so we went on.

3. Changed to our E-85 metering blocks and pulled 401RWHP ( still lean ). 3 power runs confirmed.

4. Jetted up another 5# and pulled 409RWHP ( confirmed )

5. Swapped over to our PCD PowerOX Fuel ( $6 gal ) and pulled 422RWHP ( and was fat ) ( confirmed 3 runs )

6. We dropped the jets back 5# to our original jet and pulled 427RWHP and confirmed with 3 runs.


At this point we have killed 12 hours and 40 gallons of fuel, and drove the folks at the Sonic next door crazy… they don’t even know what we are doing, but the import guys were all standing around wishing they had some of the smoke we were making…


Random thoughts;

E-85 is a pretty decent fuel for $2gal, but presents some other problems that are inherent to high alcohol fuels, including oil contamination, lack of lubricative qualities for valvetrain, carb deterioration ( over nite ). I’ll have to go back in the archives and re-vive some of my old ALKY carb notes and get on an emulsion system that I like better as the “Atom Smasher” metering blocks don’t like the lower specific gravity ( density ) of the lighter OXY fuel.

We will have another series of testing to optimize the timing curve to utilize the early boil on the Power OX 108.

Pretty sure that is why we made better power with the PowerOX 108 as it is our blend of Petro and Oxy fuel. I will also have to work out another oil package for the E-85 fuels, so we don’t kill our rings and guides.

Fuel prices were included for reference, PCD fuels can be reduced with multi drum purchases.

Once I get a couple hundred more runs in on the stuff I will probably have some E-85 carb stuff ready to go.

I can get more technical if you want, just let me know I have been accused of being too technical so I tried to get it ground down to the basics.

SOME MORE INFO FROM www.trackforums.com

I was told at a place that use to sale E-85 that the state of North Carolina is going around to stores that sale e-85 and telling them they must buy there holding tanks from the state for E-85 now. With the expense of digging them up most places are saying heck with it.
