E-85 ???
- Thread starter TTA976
- Start date
I'm not sure if you were drinking E85 (and now you are presumably dead) or you had an epiphany with some good tech info that you posted up that came to you when you when inebriated (even though you never have good tech info, even sober!!!!). Either way, I am sure it was comical...and now I am sure you wish I was dead instead of bumping your worthless post. :chat:
On a more serious post, yes E85 has its place. It burns A LOT cooler than regular petrol and has an octane rating around 104-105. Burning cooler means lower EGT's and coolant temps that decrease up to 20 degrees on a vehicle running around 200.
Downsides to E85 is that it is very hard on older fuel system components. Expect a 2 year life span on pumps, filters, and seals. You also need up to 30% more fuel and the injectors will need to be cleaned as they will gunk up if not used regularly. And E85 is not always E85...you really need to test each and every tank of ethanol you purchase. If you run E70 one tank but are tuned for E85, bad things can happen if on the ragged edge.
The biggest downside is with methanol and E85 your car pretty much WILL not detonate. Instead, you will skip straight to melting pistons and seizing bearings. There is no warning.
I will pass on running it for now. Someday maybe.

Where are you from again? Mississippi ?
Still running backwards in the cornfields with your pants down?
Now you made me forgot what I was going to say...

Ya'll are funny as hell, i needed a good laugh :chat:
Is all race gas bad for our o2 sensors?
They sell two versions of race gas here. One is unleaded and has 102 octane. I thought this was fine to run in our cars. I have put a few tanks in and the car runs great on it and I have had no issues with the o2 sensors after running it. The other race gas is leaded and 109 octane. I was told not to put this in the car as it would smoke the o2 sensors.
As far as E85 goes, I thought you had to change your whole fuel system, lines and pump, to even run this type of fuel in our cars. I had a 2004 flex fuel Tahoe and tried it a few times. Although it was 50 cents cheaper, the gas mileage was much worse and it ran very rough, especially when it was cold out, so the savings really didn't seem worth it.

You're lucky I deleted my original response to that ^^^. I couldn't make it rated PG. :aggressive::tvhappy:
Well, Joe, you finally won one against me.
Score:
Joe-1
Jason-You can't count as many as I have won
Leaded racegas is "bad" in the sense it will eat your o2 sensors and clog cats. The best unleaded gas you can run is MS109. It is oxygenated and 105 octane. You probably are running this or VP's version it sounds like. There is no downside to running leaded gas in our cars except replacing the o2 sensors....which are $20 and take 5 minutes to replace. If you run a wideband they are of course they are more.
You don't have to change the whole system, just certain components that aren't E85 compatible. Walbro's aren't, but they can take it for awhile. They have a new 400LPH coming out that is compatible.
With that being said, I bet our stock feed line would be maxxed out around 500RWHP on E85 and our back two cylinders would run VERY lean around the mid 11 second mark, if not before, if you kept the stock RAILS.
There is a reason you need bigger rails when trapping 135 or you will have higher EGT's, a leaner AFR, and more detonation in the rear cylinders.
Common issue, just not seen on TTA's because people can't go that fast before lifting the heads. On E85 it would become an issue.
Jason is my name, just like the bottom of all of my posts say
Forgot to mention thast Zeitronix has a sweet E85 sensor, but our computers can't compensate. A newer computer can...
