I have never had my truck dyno'd so I can't really tell you. All I can relate are the times that I have "run" into all manner of diesels both towing and solo and I have whipped all of the 7.3's, most of the 6.0's, modded or not, and stayed with the 6.7's in 2008-2011. Now I have to say that hauling my 2002 Airstream 30' Classic (about 10,000 lbs) with my truck weighing in at 8100, I passed alot of diesels towing similar weights including Fords, Dodges and Chevy's going up the mountains in Utah and Nevada. Mileage average for the 7,000 mile trip towing my AS averaged 8.4 mpg. I can only go by that and SOP feels like rwhp is over my totally hopped up 7.3. I would be happey to attach my mods on my 2002 7.3 so it will show as a comparison.

Lots of weight, the X all loaded up, the 25' TT all loaded up, and the 16' boat all loaded up. About 65MPH most of the time with some hills.

And you know, just because you pass someone, doesn't mean you outpulled them...... they may not be going as fast, or they may not think they need to prove anything to you

Maybe a 6 leaker with a SCT tuner would clean my clock, but I doubt it, maybe slowly pass me but not clean my clock. The thing is that after he passed me and he got to the top of the hill, he'd have to pull over and puuck his guts out, then I'd pass him. If you go to any Ford dealer's shop and look in, most of what you see is 6 leakers. Now that most all of the 6 leakers are past warranty, the poor slob that buys one is really hanging out. I feel sorry for them since most think they are getting a really good deal on a nice Ford SD diesel but it will eat their lunch.

Thats the truth! This last trip on the way home I was passed by a dodge diesel pulling a fairly big 5th wheel camper just before a hill. I thought it would be funny to pass him going up the hill but it would have put me out of my comfort zone pulling the two trailers which was not worth it with the family aboard. He did lose a little speed when he hit the hill and it would have been easy for me to pass but I held back the urge.

No you didn't. The 6.7 didn't come out until 2011 so no way you "stayed with them" and when they did come out there is absolutely no way your 3v V10 stayed with one even with the tuner. Sorry that motor is a beast, and I don't think even the biggest honest v10 lover on here will deny that.

I can agree with some of what you say, But, a 6.0L with nothing but an SCT tuner will clean your clock. Period. It will put down at least 350HP (low estimate). I don't think your v10 will hold against a well tuned 7.3L either.

Sorry, must have been the 6.4, anyway it was a 2008
ford diesel. I can't keep up with all of the diesel engine changes these past few years. It was the last of the International diesels that required the cab lifted to change out the glow plugs or work on the engine. I wonder what that's going to cost once the warranty runs out.

Hey Bill, I never saw this. lol My build will hopefully be ready sometime late next year. It should be fun, but I'm pretty unsure on how the drivetrain will react. The ZF5 has little input shaft syndrome... I'm looking for it to be around 600-650hp on fuel while still having the ability to tow or be a DD if needed.

You forgot to mention the duel fins on the turbo that also croak when filled with soot. Oh, and have you read the hundreds of TSB's for the 6 leaker? It might change your mind.

Hmmmmm......my "6 leaker" has been in 0 times for any issues in 97k miles, and it's been modded! How can this be possible? Ford must have screwed up and it's really a V-10 with a turbo and no spark plugs and 2 less cylinders! Because according to these guys no other engine ever made can make any power or last longer than 600miles. Give me a break your inferiority complex is getting ridiculous!

I also love your constant refrence to the "6 Leaker" we get it...you don't like it... get over yourself. I bet if I went through all your posts, 1/2 of them have "6 leaker" in them. Your personally selected crown of thorns, I guess.
Lastly, in responce to your earlier post about my mods list... Like posted above, I should be in the 315/650 (RW) hp/tq area now with no major mods. Now, how much do you think I have spent on my truck/mods for those numbers vs. your 08 with your mods?

I going to go out on a limb here, but I suspect the "diesel resale" thing is not going to count for much after the warranty is up. And if it still does bring a premium, well, PT Barnum's cometition, David Hannum had a saying for that...
