I don't think your allowed to flame MD...it's in the guidelines..somewhere.

i actually gained a bit of mpg when i finally got it tuned right! i dont understand that one, i used to get 250 to a tank on the highway, once i got the turbo on and fully tuned i run 310 constantly???

Dwolsten, you mean burn efficiency, not MPG. A b18 burns air/fuel mix more efficiently than a Chevy 350.

Man, i dont think a turbo should make a difference with your MPG, WOT or not. Say if your going a mile, its going to take you less combustions with a turbo engine, because there's going to be more air and fuel in each combustion. But i dont think your going to pick up any MPG if you went with an n/a car; Going the mile, your going to have to go through the combustion cycle more, but at less of a fuel and air cost. These two extremes should equal eachother out, am I not right? With a supercharger, i can see it making a difference because the engine has to turn the SC with its own power, but the turbo doesnt drain any of the engines power.

If you sprint a mile or walk a mile, isnt it going to take the same amount of energy??

No... Go sprint a mile and see how you feel. Then walk one and see how much better you feel. Keep in mind that gas burning in an engine is not the same efficiency through the whole rpm / mph range. If you floor it, you are not getting nearly as an efficient burn as if you ease into it. So sprinting a mile takes much more energy.

 

[hettseypoo455]

Ah, i should have used "work" instead of energy. It takes the same amount of work to walk a mile as it does to sprint a mile. You're more tired after you sprint a mile because you did the work faster.

Turbo or not, you arnt going to get as good of a burn at higher rpm's.

If you make 1 big explosion, or 1,000 little ones,(both using the same amount of fuel) shouldn't the force produced by each equal eachother?

Nope, I mean MPG. Do people with turbos never drive anywhere besides their locality? If I'm taking a long trip, I don't want crappy mileage just because I can accelerate fast from a stoplight. If all-out acceleration is your only goal, and MPG is not a concern, then you need to forget about turbos and just get a big-block V8 (and turbo that if you want even more speed).

Some people actually want a car that's good for things besides drag races.

 

[hettseypoo455]

i dont think turbos give you bad mileage, period. Long trip or not. And do you think big block v8's get good mpg?? i think you would definitly be faster, and get better mpg than a v8 if you turbo'd a 4

more air requires more gas. hmm. if i need more gas then i must be useing more gas.
plus i saw a thread like this a while ago and the turbo guys were saying that they noticed a decrease in gas milage. old thread

depends totally how you drive, if I keep it out of, or in low boost its not a whole lot less than stock, if I run it through the gears all day though I'll go through half a tank.
