Fine. Dont worry. You're not the only chicken on this board. -
I wouldn't waiste my time jacking with e85 with something like that.Comment

How much could you really gain doing that swap?Big Rooster Racing

Probably just shittier gas mileageComment

I was reading where a Mach 1 gained 30whp and 40trq.
That could just be from tuning over stock too.
320rwhp. 7.67 @ 90mph 1.7 60'

I guarantee you that's what it was from. You're also not a modular 4VOriginally posted by 91CoupeMike View PostComment

A 9:1 6000 rpm engine isn't going to gain much by going to a fuel that is more resistant to detonation.
It could even lose power, since the incoming fuel charge will absorb more heat from the combustion chamber.
Crank up the compression, lighten the reciprocating weight, lighten and strengthen the valvetrain, then add more cam to increase RPM and cylinder pressure. At that point you'll have a reason to go to E85.When the government pays, the government controls.Comment

lol, this n!66@....Originally posted by 46Tbird View Post
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.
Top fuelers run nitromethane specifically because of this. Nitromethane even carries it's own bit of oxidizer from the NO2 tagged onto the molecule...Full time ninja editor.Comment

Sounds great, thanks for the crappy thermodynamics lesson. Now convince your buddy to swap out his entire fuel system to slaughter whatever gas mileage he may be getting and end up with no gains because his engine is not being taxed enough to take advantage of it.Originally posted by majorownage View Post
The topic is E85, not nitromethane. Try sticking to the syllabus, Bill Nye.Top fuelers run nitromethane specifically because of this. Nitromethane even carries it's own bit of oxidizer from the NO2 tagged onto the molecule...When the government pays, the government controls.Comment

Go back to dirt racing billybob, we are talking science here.Originally posted by racrguy View Post
Hey thanks! That's Bill Nye in my siggy!Originally posted by 46Tbird View Post
No thermodynamics here. Easy freshman chemistry. Nitromethane is an extreme example and the principle of the horsepower gains are the same mechanism.
Just FYI, I'm not advocating switching over either.Last edited by majorownage; 11-12-2013, 02:07 PM.Full time ninja editor.Comment

How about instead of just refuting me, explain how it works.Originally posted by 46Tbird View Post

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.Originally posted by majorownage View Post
E85 doesn't do that. Your statement that horsepower gains are from the same mechanism is not true.When the government pays, the government controls.Comment
