E85 conversion Aluminum projects

Post by TonyB » Fri Feb 26, 2016 10:43 pm

Hey guys,

I'm converting my Supra from "Premium" gas to E85.

A bit of backround on why will probably make this post more interesting. If you research octane and compression, you'll find that as you increase octane you also increase the compression at which it will spontaneously combust. From a simplistic standpoint, more compression equals more horsepower. If you have enough compression to cause spontaneous combustion (also referred to as detonation or spark knock, I believe), the "power" stroke of the combustion cycle will occur before the piston reaches top-dead-center (in other words, motor goes boom after this happens a lot). The octane different between Premium and E85 is 91 to 105; a considerable bump.

There's quite a few addition advantages and some other shortcomings that I won't get into right now.

On to the pictures!

So, 'Premium' is 91 octane?

Dang...
The lowest quality in sale here in Norway is 92 Octane, but that is luckily only for sale in some of the larger cities.
The rest of us use 95 or 98 Octane. (95 would be our 'regular', and 98 'Premium')

Are you certain your E85 is 105 Octane?

Yep :/. Some Walmart's and Costco's gas stations have 93; I think there are three in Des Moines. The good news is that E85 is very common; I have a gas station that has it less than 1/4 mile from my house.

I guess it's 100 to 105 octane:

The pump says E85; but I've been told in the winter it's E70. The good news is that the flex fuel sensor will read the ethanol content and the computer should adjust accordingly.

You will LOVE e85. Smells great, car runs great. I had a dsm that I converted to run on e85 probably about 8 years ago.
I was really hesitant to convert but did anyway. Filled up with e85 pulled out my laptop and upped the timing across the board and drove away. The car LOVED it.

There is no Leaded gasoline sold in the US. Wide spread sale of leaded gas was phased out between 1972 to 1986, with the EPA officially ending it's use in automobiles in 1995. E85 is a blend of gasoline (15%) and Ethanol (85%).



Hope that helps clear that up.

Few more updates.

Note, the engine is on an stand and is flipped upside down in these pictures. So picture them rotated 180 degrees.

To get the fuel pressure regulator in a better spot, I threw together a quick design for this bracket. In retrospect, I would make the plate a little bigger to make it more aesthetically pleasing; it looks weak, but is surprisingly rigid.

I had some issues with oil draining from the turbo, so I had a bung welded to the oil pan and milled a blockoff for the stock drain.

Looks good. You could have just rotated the pics yourself before posting them... I had to stand on my head to look at them. :)

i know pump gas in not leaded but a lot of race fuel still is. i ran 116 leaded in my race cars threw all the 90's when i took it down to sea level, so had to take my wide band 02 sensors out when i wasn't tuning cause the lead would coat the element and it would loose accuracy.

i had the E confused with a C. ethanol is great though, you can make some real power with it.

also those brackets look great.
