So Guys what you think of running e85 vs. race gas? then e85 vs. pump on the street? Is it much better. They say it pollutes a lot less. so i guess it could also help pass emissions. Opinion guys. I personally have never used it would be nice idea since i can tune the car for the e85

A good friend of mine was on a team that converted a few cars to alternate fuels for a collegiate competition. E85 takes a lot of work to make it work right. All aluminum in the fuel system has to go, E85 will either eat right through it or become contaminated. It also makes less power than regular, they added a supercharger to make the truck a little faster than stock. I'm pretty sure the fuel and spark tables were completely re-mapped. Something with the fuel pump has to be changed, I just can't remember why.
My point is that it's not a very simple process. I'll have to see how GM makes cars that can run on both, maybe something has changed in the years since the competition. |

E85 = 85% ethanol. Not only does it not have the same amount of energy as gasoline (less energy = less hp), but it also reduces your fuel mileage and costs more than gasoline. Apparently alot of corn lobbyists paid off most of DC to get this crap shoved through.

Go with race gas! It smells cool and the extra money you spend will help the economy!

I though e85 could be compared to kind of a cheap race gas. I has less energy but tuned right would bring more performance and fuel economy than pump gas. It seems as race gas is superior but what about pump vs e85? i heard it should be around 102 octane (compared to 93-94 for premium) and if you don't tune it specifically for e85 it would be worst economy and performance wise but tuned right (more timing about 6-8 degrees)

Notice how GM has failed to mention the MPG for E85......
If I recall (and correct me if I'm wrong), the A/F ratio on straight alcohol is in the 7.5:1 range. I'm sure the 15% gasoline helps that a little, but I'd like to know what 20 mpg on gas would equate to in E85. I'm betting 11-13. |
