race gas compared to E85 when converted - 08/30/09 03:19 AM

I have in another topic the problem i am having affording race gas on the streets in my Dart, one idea was to turn my motor into pump gas another just convert to E85.
I want to hear dyno #'s or track times from those guys that have tried this conversion......
was it worth it?
did you drop off allot ?

Thanks, Tim

My car didnt change AT ALL when I changed over to
E-85 and I havent turned up the timing yet... 14.1:1
compression
EDIT
Well worth the cost... you can make up the carb
difference in short order

what about delivery fuel system ?
I have a magna fuel 500 pump and filter, 2port regulator .

Your system need to pump at least 30% more volume over
gas... I use the same pump(pumps in my case, 2 Holley
black 150's) and a 4 port Mallory return style reg,
all these were used on my 1050 dom on my race gas
set up then I changed to a 1050 dom on E-85

An easy YES Race gas $9.25/gallon, E85 $2.29/gallon. That pays for the conversion in short order. And E85 runs a little cooler. I changed more than just the carb, so my ET is not a direct fuel comparison. I estimate the E85 was 0.15 faster than gas, and methanol was another 0.15 faster than E85 in hot summer weather. The differences get smaller in colder air.

Now you've hot me thinking about it...Does anyone know if Holley 2300, 2-barrel sixpack carbs can be modified to have enough fuel flow capacity to run E85 and feed nearly 700 hp?

I dont see why not... your increasing the amount of
fuel not the air so if you have enough air flow you
would just need to increase the fuel volume by 30%
across the board... I dealt with Quick Fuel so you
might talk to them

wish I would have gone this route before the summer, I would still have $$ left on my Sunoco Gas card !!!!!!!!!

I will be starting this conversion after the 8th(i have a track rental)

Cant wait !!!! Just dont tell anybody I went "Green" I hate tree huggers !!!

Mr. Legend,Van Jones will love you for it!

He's in charge of the "Green Energy" department! I also plan on making the switch,as soon as I can afford a new QFT 950,and get my E-Heads shaved for 12:1 compression.

Thanks for the tip. I found a 500 CFM E85 2bbl that's used for circle track racing on their website. It looks like with a little modification to the top of the carb it would be a bolt on replacement. It sure would be nice to have a trio of 500CFM E85 carbs under my shaker. I'm going to have to give them a call tomorrow to see how much that would set me back, and if they think it can be made to work on my application.

Mr Peabody should i do the volume check first with gas and then figure from that? Brad

Is there a problem with E85 ruining oil like is the case with methanol? S/F....Ken M

Re: race gas compared to E85 when converted - 08/31/09 01:36 AM

Well I'm finally going to try this E85 stuff. I stopped at Jegs and picked up the Quick Fuel conversion kit and an alcohol rebuild kit. So next Friday I'm going to hit test n tune and see how it works. I'm currently running a Holley 950 on a 400. I ran the numbers and as much as I race the E85 can save me $600 a season easily. I think the kits ran about $200 for the rebuild and E85 metering kit. My fuel pump is the only part thats iffy ...but I'm gonna try it and if the pump fails or isn't enough I'll replace it.

Really you need to figure your engine consumption
as it is now then figure 30% more and see if your fuel
system will do at least that much

No its nothing like meth... get get it warmed up
before your run... I get to about 185 degrees at the
end of my run each time and when I get back to my pit
spot and shut it down it back to about 165... I havent
seen hardly any oil contamination, I went last season
with 1 oil change mid season and it still looked good

summit has kits for the dominator by quick fuel for only $270 !!
dam if thats all it takes I'll be set up right after the 8th track day !!!

I'm getting excited over here !!!!!!!!!

Re: race gas compared to E85 when converted - 08/31/09 02:42 AM

I'm just waiting for an E85 pump to come to my area. Then I'll convert and maybe up my compression and camshaft for more power on cheap gas.

Re: race gas compared to E85 when converted - 08/31/09 03:55 AM

If the dam ups shows up Mon. i should have my e-85 Dominator back from AED i sent it to them for the conversion and by next year we will have e-85 in our town, for now ill have to drive 127 miles to get it but it should be worth the effort.

I just converted and thought I would try my carter mech pump.............no problems! 1/8th mile racing with a steath headed 470 running 660s in the full 1/8th.

Re: race gas compared to E85 when converted - 09/01/09 12:01 AM

what about the concern that it's not always e85, some times it on 70 -75
or winterblends?

Mid summer isnt a problem... but I check the drop
sheets at the station to see what the percentage of
alky it is.... they drop X gals of alky and X gals of
regular into the same tank OR you can get a tester
from Quick Fuels

I did a home conversion on a Holley 950 and it worked OK, but it really needed the boosters changed to optimize it for E85. If you can't get it rich enough to slow down the car (then lean for optimum), look into having boosters swaged in that will flow more fuel.

And I fill a 55 gallon fuel drum whenever I go to the station. In late summer, buy enough to last until the summer blend comes out in late spring or so. Call and test.

I tried this, went to 4 different places , asked the attendants, you would have thought I asked them to explain Nuclear fusion. In fact on the pump it states to ask the attendant which blend is currently being sold, They didn't know anything about it.

None of them know....or care, you have to ask to
see the drop sheets for the E-85... they will have
to get off their butts to look for it but all the trucks
have to give them the drop sheets.... I get my fuel
from Meijer and even the woman manager found it, now
she knows me.

Re: race gas compared to E85 when converted - 09/01/09 03:14 AM

I called the semilocal station that has E85 about their drop sheets. I messed up because I called from work ( I work for the state of OK environmental regulatory agency, no Im not an environmentalist, LOL). The girl who answered the phone obviously read the Caller ID. She started sturrering, everything is legal, we do it by the book, etc.

I reassured my call was not work related, finally I had to call the main office. The lady there was very helpfull and gave me the latest drop sheet info and told me to call back anytime.

Okay, before i got check these drop sheets, what am I looking to see #'s wise thats good and what to stay away from ??
