E85 on a n/a foxbody?

[Nash B.]

lol, this n!66@....

Most of the power gains in e85 come from the fact that more fuel can be burnt per molar unit of oxygen. Even though e85 has less energy per mass of fuel, the fact that more can be injected into the combustion chamber more than makes up for this.

It isn't because E85 is more resistant to detonation and allows you to run higher cylinder pressures (dome pistons, forced induction, nitrous), which more than make up for the fact that it has less energy density than regular unleaded?

i dont care about all this science mumbo jumbo, but can it not be argued that when properly set up, e85 outweighs 93 octane, every time?

i also agree on a daily driver no way, but for a weekend car with the proper fuel system, e85 will out run 93 oct. and the price of fuel is the main advantage.

i wouldn't do it on your fox mike, but if you get a daily and leave the fox for fun, then put it on e85, throw some power adder at it, and let it eat.

as i always say, if you want real answers and not just a couple random half ass answers, aski this shit on yellowbullet.com

Protip: you're dead wrong

You've already said yourself how nitromethane works: it is an oxidizer, releasing free oxygen into the combustion chamber more efficiently than it can be ingested from the atmosphere.

E85 doesn't do that. Your statement that horsepower gains are from the same mechanism is not true.

Ya'll are fumbling the ball seriously. First of all, you cannot draw a comparison between fuels by varying the engine specifications. Of course with a higher octane rating will allow higher compression. Any shade tree redneck knows this.

I am trying to compare fuel types ALONE. Try running all different types in one motor independently.

Why do people pick up power from switching from race gas to ethanol/methanol? It's not because of more timing. Race gas allows the spark to be advanced until the engine maximizes it's power. Spark advance will increase power to a point, but once that point is reached, there is no reason to add anymore. Yea, it won't knock if more is added, but neither will it add power.

There are always gains from switching from gasoline to alcohol specifically because of the decreased requirement in amount of oxidizer per molecule of fuel. Additionally, ethanol DOES have it's own oxidizer: "OH," which makes ethanol an alcohol.

In the dirt track world methonal and gas they have similar horse power numbers but methonal makes more torque.

Probably from the reduced temps that they run at. Would be my guess.

additional timing.

holy shit, the internet and the free information avialiable conveyed, are worth exactly what you pay for that information, in here.

ps, i'm on an engine dyno 3 days per week. E85 is still garbage.....methanol is bad enough to keep away from moisture.

wrong, hp is not measureable, it is figured from torque which is the only type of power that can be measured. so to say an engine makes more torque and the same power is completely ignorant.

Well they could could produce their peak torque at the same calculated rate.

It makes similar I didn't the exact same Einstein. All my information I have heard comes from Dennis wells and I'm pretty sure he's dynod an engine or two.

[Super Coupe]

probably regulations

A lot of people who run gas in dirt track so it for the rear percentage. In a long race you burn a lot more methonal than gas.
