Ford 7.3L GASSER rumor confirmed

OK. Everybody put it on hold for a little bit.
Im out of popcorn.:B

Shiner , he is comparing his 2010 truck to 7-10 year older trucks.Hes not posting about the present because he knows nothing about it. My 2016 makes as much or more power at 1600 as his does at 4200. :S

So you are saying that if a 6.7 Powerstroke had to run at 2500 RPM to keep a load at speed you could do it at 3250? HAHAHA!!! That's funny right there. You need to get out more. I have driven plenty of 5.4's in my time and although a great long lasting engine low end power it does not have. You might be comparing to a 6.0 Powerstroke , that I would believe but not todays oil burners. You would be lucky to only turn 30% more than the 3.5 Ecoboost.

No, I didn't say that. You said that. I'm towing an 8500~lb travel trailer. Around the southeast, I don't see more than 4200rpm where my previous Cummins powered Rams saw 2900rpm. The 5.4L actually tows faster up the hills than my '03 250hp Cummins Ram. FWIW, I run 2000~rpm 65mph in OD on the flats with the 5.4L F250. Any hill will put it in direct at 2700~rpm. Steeper hills we pull in 3rd at 3800-4200rpm 60-65mph. All relatively quiet. My '98 12v 5spd/4.10 ran 2500rpm at 70 in 5th towing or not. There was no upshifting or downshifting possible with it. Sounded like a shop vac 10 hours a day. An F150 HD with 3.5L Ecoboost would do a fine job with our travel trailer. I've never owned nor would I ever own a 6.0 PSD. I have no desire or need for one of the newer diesels. The 5.4L is a long way from retirement.

:S :W

Yeah, I would have to raise the BS flag on that too. I drove plenty of 5.4L SD's in the past as well and all of them would down shift to 2nd or 3rd at the sight of a hill when towing. They would get the load up the small hills, but it would be screamin' at 5,000 rpm doing 45 mph to get it there. I could just hum along at 1,700 rpm in 6th in my 6.7L CTD pulling the same weight up the same hill.

You're calling me a liar. I'm convinced you're a liar. I guess we'll just have to leave it at that.

Yes, I am calling you out for saying that your 5.4L only revs 30% more than my diesel pulling the same load BS. I have experience towing with 5.4L SD's and there is no way it will tow a 10k trailer up a hill at just 2,340 rpm which is 30% more than the 1,800 rpm my truck would do going 65 mph in 5th. Every 5.4L that I have driven would be screaming much higher than that at even the slightest of hill, and it you would consider yourself lucky if you were able to do the speed limit.

Hydrogen should be thought of as a energy storage medium ,like a battery.

dead end

Does anyone know if the hydrogen engine which Toyota is now selling in California has any sort of potential as a tow engine. Built to thecorect size of coarse.

Diesel has the 'best' (for now) efficiency of ICE's...at about 40%. Meaning 100 BTU's of energy in a gallon of diesel fuel will produce about 40% of that power down to pavement. Gasoline is even less than the 20% less energy vs diesel...because of the architecture of gassers...

But, with the newer stuff...expect gasoline to move up that efficiency curve...as will diesel

Hardly a tow vehicle, but the redesigned 2.5 liter 4 banger in our new Camry has some real mad science stuff in its innards that boosted HP to 203 and a claimed thermal efficiency (by Toyota) of 40%. Still a gutless wonder with torque at 187 ft lbs at around 5000 RPM. What I'm really curious about is the LOW viscosity engine oil required (0W-16), the computer controlled variable displacement oil pump, the electronically controlled thermostat, and the hybrid injection system of both direct and some other type......

I mean that’s what I look for in a vehicle. 30% higher rpms (you mean 100% higher by the way), 30% worse mileage and half the torque or less.......where do I sign? I’ll take 2!

No, I meant 30%. Sorry if that hurts. Lol!

My 5.4L F250 is the first truck I've owned in a very long time that I'm not anxious to trade for something better. If it were as bad as you wish or imagine it were, it would have been traded long ago. :B
