Ok, I was fooled at first, but now I'm absolutely convinced that this guy is a troll. You got me.

 

i will quote my own post for you people who can't comprehend

what you wrote you would be doing the same speed. when you increase the (L) load and maintian (R)rpm you increase fuel usage(F) so logic demands that these three L R F are related and always will be

 

Hey, what's a big rich engineer like you doing at home on a Friday night anyways? Seems like you should be out on the town in your big fancy Hummer.

I'm personally too tired to do anything but sit right here and watch you make a complete fool of yourself

Didn't you say you got your "engineering degree" from South Harmon Institute of Technology?

I hope a few people got that one

 

That was a great movie

 

Ok, i've been following this thread since it first started, and have read every single post that has been submitted, and I've been hesitant to say anything, I was just waiting to see if dancodanco would come around.
I've been really thinking about what he's said, and i considered what everyone else has said.. And i hate to say it danco, but i have to agree with everyone else. While more rpms generally does equal more fuel usage, it is definetly not an exact science at all. The one thing that makes the real difference is how much pedal that you use. Like has been said dozens of times, lower rpms wont equal better gas milage, if you have to use 75% throttle to maintain speed. If you stop and think about it, it is really not that complicated of an idea. Your idea is a much to simplistic analysis of gasoline engines, and really cant be used when it comes to 4500 pound trucks. I'm willing to have a calm discussion with you as long as you actually listen to my, and everyone elses reasoning.

Honestly I don't know what to believe. I've tried it both ways...just using the truck regular and using the overdrive off around town. I honestly think I get better mileage just using overdrive on all the time, but turning OD off does help with driving through steep hills.

 

Is it just me, or is this guy beginning to sound more and more like Mattineer??

What happened to him anyway?? I havent seen him around here in a while.

 

I tell you what Danco. If you have a manual car or truck you put it in 5th gear or whatever your final gear is at 10-15mph and see what kind of mileage you get because from what i read in the first 2 pages (I didn't read the other cuz life is too short)of this post is that lower rpm=better fuel mileage correct?

 

HI!... All I know is when my truck was stock I got about 17mpg with the stock 3.55 gears and 30.00 inch tall tires. That was with a P.I 5.4, 260H.P/350FT/LBS of TQ (flywheel)

Now I have 4.10 gears, 28 inch tall tires and 430H.P/500FT/LBS of TQ (flywheel) and get 21.3MPG. It's called volumetric efficency.

 

v8 4.6 4x4 3.31 gears 275/70/16 11.5 mpg i just did it today. anybody know how to get my mpg up?

 

well according to Neal you should put 12 inch wheels and a 7 to 1 rear end and sup up your engine


I have just finished reading this whole thread and it is very entertaining.

 

HI!... Jealous? MUCH.

 

Neal you are right I am very Jealous. If you are getting that kind of gas mileage with that set up. I just don't see how you can do it. can you give us some more details on what you did to get that kind of gas mileage out of that engine and gear ratio.

I am not only jealous but in aw. and I think you are my new hero.

 

Last I saw, he had been banned on three different forums and at least five different usernames LOL!
