All my runs have been NA, most of my quickest runs are on E85 you know the fuel you can't stand and knock every chance you get.

Damn now you are outrunning twin turbo ecos and uprev modded titans on 15% water. You are a bad a$$ aint ya :what:

Less RPM = Better mpg is a myth in my experience. It takes a well balanced setup. The shorter the stroke and the longer the rods the more rpm it will like at cruise. A Titan has a relatively short stroke and I have found my mileage is roughly the same in 4th or 5th at 80 mph. At 80+ mph you begin to reach a point where the engine is loaded so heavily in OD it starts dipping into power enrichment and kills your mileage.

You see, once again you are the ONLY one with a Titan that has this "experience". I don't care about any strokes and rods. Besides maybe you wanting a longer one. No need to go into your gibberish again and trying to sound intelligent. You contradict yourself at every turn. You really need to read what you are posting if you are going to lie so you don't catch yourself in it. Remember this statement:

Bone stock Hemi trucks get crappy mileage, stock 4.7s get worse mileage. 2,600 rpm at 85 would knock on 19-20 mpg all day long going between DFW and San Antonio. If I stuck to the 75 mph speed limit and 2,200 rpm I would get 21-22 mpg over the whole trip.

The only guys that ever knocked the 4.56s in regards to mileage are the ones that didn't have them. The MDS trucks are known to get 24-25 mpg @ 70 with 4.56s and custom tuning.

First, less RPM as stated about your Dodge(Shocker) yielded you better mileage. So that "myth" you eluded to is true. First lie. Second, Go find some of your fanboys if you have any left to come on here and back up your statement of a 4.56 truck getting 20mpg at 2600 rpms.

Bottom line, I have driven probably twice as many miles as you in your life. Maybe even three times as many. It's simple fact that lower RPM's yield better fuel economy, period. Why continue to argue it? Sometimes you just need to stop. Think to yourself, do I want to get into this web of lies any deeper? As for all of the other stuff in this thread, post some slips. it's as easy as that. No more "If I had headers, if the DA was better, if I had trutrac." There is no room for speculation in drag racing. You run what you run, period.

Lower RPMs DO NOT, CANNOT, IN ANYWAY be linked to better mileage. Lower speeds can be solely to blame there, but not RPM. Wind resistance increases with the cube of the speed. To go twice as fast takes 4 times the power, BUT NOT NECESSARILY 4X THE FUEL. That is where gearing plays a part.

Try this one, I had the 26 gallon tank, verified by running out of fuel, pulling the truck with a tow strap down the street to the gas station, I only put 24 gallons in it. Long story short, I went 475+ miles on 23 gallons more than once on the highway at 75-80 mph with 4.56s.

You have no idea what the hell you are talking about. Are you going to tell us next that you have a degree in physics.

Yep I hate ethanol in my combustion engines. I can get 1-2 mpg improvement with real gas over the e10 and e85 kills my mileage and seems sluggish. I have 3 chainsaws and a yard blower destroyed by that crap and try my best to keep it out of my outboard. So yeah Im gonna knock ethanol in my gas. Its not much cheaper anyway.

[Atlas09]

Wind resistance is a huge part of it, I agree there. But again, the things hemi has been saying seems to only apply in his world. My f150 with 3.73 loved 55 to 60 mph. 80 plus was a chore for the 5.4. Lower rpms and lower wind resistance go hand in hand, Unless you are on a dyno. A low rpm hyper mile technique is the best for fuel mileage. And back to the point of this thread, my truck is on the dyno today... Then I'm going back at that tundra.

If you would, start a fresh thread. I hope you get your issues fixed with the tune. Titans with headers sound great.

[04GreenT]

So if a higher gear doesn't effect fuel mileage and makes the truck way faster, why are all the fastest titans running a 2.94 ratio? Probably because they get decent mileage on the street and they are the best gear for how the titans tranny is set up. But your titan is different right?

Nope but I do know the effects of different gears and the basics of gearing a fullsize truck. With OD transmissions we are running gears that were considered econmy gears in older trucks. For a small engine to push a heavy aerodynamic brickwall into the wind, deep GEARS reduce the load on the engine. At the end of the day at 70 mph on my Hemi we were talking 400 rpm between 3.55 and 4.56. From 1,800-2,200 rpm but it had much more torque to the tires in every gear at all throttle positions.

Apparently you don't. Just curious, what's your education background? Any formal education from a university? Or are these all just spit-ball ideas? Because nobody agrees with you... Ever.

This is the same old 3.92 vs. 4.10 vs. 4.56 gear debate I got with the Ram. I went from 3.55 straight to 4.56. That being said compared to the Hemi with 4.56s rolling on 32" tall rubber my Titan feels lugged now with its factory 33" tall tires and 3.36s despite having more torque. I'd love some 3.73s.

Like I told them with a shorter stroke of a small block truck, don't fear the gear. My Titan even with 3.36s downshifts twice on this hill.

Actually a short time after having regeared my Ram, my uncle who is a Mechanical Engineer and I were talking about ways to make his LM7 5.3 powered 06 Sierra pull his 7,500 lbs trave trailer better. He had 3.23s and we discussed a gear swap. Not two weekends later we swapped the 3.23s for 4.10s and I adjusted his shift tables in HP Tuners to match. He lost NOTHING MPG wise, gained mpg while towing, and gained a hug amount of useable power everywhere.

[04GreenT]

An older member Jgrace ran 3.73 and had the same mods as Firelife.. with the exception of a dual exhaust and the 4" intake.. please tell me why Firelife is neat a second faster in the 1/4 mile.

He asked your education background and you said your mechanical engineer uncle asked you for advice? does that mean youre smarter than him? I went through a brief stint as a mechanical engineering major before swapping to business and I'm quite certain he would have covered gearing and effects of gear changing during some simple word problem freshman year.

I'm two years into my Mechanical degree... And I can say that this guy is so full of sh*t. Hey 06douchey, are you quoting wikipedia or yahoo-answers for your info?
