So, all this talk of flex fuel vehicles and Ethanol usage leaves me with a few questions...

I realize that to run E85 you have to modify your fuel system so that it won't be melted by the Ethanol. However, if it's a higher octane does that mean that it would be like running a race gas blend? Or will it just make a whole lot less power, as I suspect? Not that I'm planning on converting the EVO or anything, I'm just curious.

Also, there is a lot of talk about Ethanol being increasingly added to existing gasolines, does that hurt or help in regards to a car like our EVOs?

 

The gas around here moved to contain up to 10% ethanol already. First time I filled up with it I was hitting fuel cut at WOT and had to turn my EBC down about 3psi...it sucks.

Yeah, but if they start to put more ethanol into regular gas at the pumps will that start to degrade the performance of your car? Would it require a retune?

 

E85 is roughly equivalent to 105 octane, however it isn't as efficient as gasoline so you'll use about 30% more of it (fuel efficiency will go down). There are also some changes to the fuel system needed.

i agree but you do get charge cooling with the fuel and you need about 30% more due to the BTU differences i run it in my honda with no problems and all i did was retune hondata with 720cc injectors and a 255lph pump.

 

Good to see you on EVOM Doug. How is the MR treating you?? Did you get the JunBL exhaust installed? I bet it sounds purrrdy.

As for E85, since they wont let us use alcohol injection in SCCA autocross events I was thinking about running E85 next year. It would have to be way cheaper to run that than the C-16. Plus I could put my catalytic converter back on to quite it down a bit. From your experience do you think, properly tuned, that E85 will make power somewhere in between pump 93 and VP C16?

Yes, it's roughly equivalent to 105 octane, plus, like said earlier, there are charge cooling benefits.

 

yeah it would be between but you can also run E100 which will be close to c16 last i heard e100 was close to 114+ oct. but you can buy this in bay city by the 55gallon drum i think the E100 in the fall was around 2.70 a gallon and E85 was around 2.20 or so. But the cool thing is it has oxgen in the fuel and as said above it charge cools just like the alcohol injection does. Even with out the cat i think with e100 you will meet smog if they tested.

They have not got all the parts in for my MR yet so i have not been in to buy the JunBL yet i was going to do it all at the same time. This sat we are going down to waterford to watch some racing call me if you want to go.

 

What would happen if you ran e85 and had c16 injection????? Just a random thought back to studying!

 

the only thing gas has on e100 is that it has more btu's per vol. so you just need to pump more e100 then gas but you have oxgen in the e100 more so then gas.

 

Do you know if there is anywhere that sells E100 at the pump? In order for me to run it as a fuel it has to be a "comercially available as a service station pump fuel".

Thanks for the info. BTW, I will be down at DRSCCA's solo school and season opener all this weekend. PM me if you want to stop out Saturday or Sunday. I'll give you a ride in the silver bullet.

They must sell it somewhere at the pump cause of this. I just don't know how much of an issue it is if you have to have an address for a station.


Saab Unveils E100 Hybrid

Source: Green Car Congress

March 30,2006— At the Stockholm Motor Show, GM’s Saab brand premiered its promised 9-3 hybrid concept car that can run on 100% ethanol (E100) with combined cycle fuel consumption of about 30 mpg US. The car is also the world’s first hybrid soft-top.

 

saab is "born from jets" they can do anything.
