Exactly...I live at 6700 feet year-round which handicaps those N/A engines 18.5% as soon as they turn their key to the start position. My Fusion is slow as hell up here, but is a lot quicker when visiting California. On the other hand, I hear my PSD dumping the excess whenever I let off the pedal around here. Up in Vail or Breckenridge? Not so much.

 

Hello All, I'm new to FTE, so take it easy on me. I just switched from GMC to Ford and picked up a new 09 F250 6.8 V-10 with the 4.30 rear. My dad has a GMC 2500, Diesel and freeked out when I parked my Ford in his GMC driveway. HAHAHAHA. Love the truck, but am finding aftermarket parts rare. I want to "chip" the motor for better MPG, but finding the right product is proving elusive. SCT only apparently goes to up to 2007, and Bully Dog and anyother product won't support the 09 V-10. Any advice for a new Ford owner?? Pics on the way.....
BTW, reading through 434 pages of Ford owners arguing about gears, engine size and reliability is like two brothers arguing about who's got the better looking mother. DUH!

Want to add a lift kit to the truck, but read a lot about the "Cautions" with this change. Need to get rid of the Conti's;they suck.

Thanks.

 

I said "about half" if you would have read it..... I consider "about half" to be anything from 40-60%. Your psd(and mine) makes peak hp at 3,000 rpm and falls off sharply pretty quickly after that. The redline on mine is 3,600, but pulling past 3,000 is pretty much pointless with it. So while you may get it to pull to 4,000, there really isn't any point in it because you are going to be making a lot less power than you are at a lower rpm.

 

So let me get this straight...YOU said a V10 redlines at 5200 and that that is roughly twice as high as a PSD. I said my truck shifts around 4000rpms, and somehow you ascertain that 4000 is between 40-60% of 5200. Did you break your calculator?

I love it how you don't own a V10, but you sing the praises of it. That allows you to backpedal at will by saying "I don't own a V10" but it smokes my 7.3...Well, my 6.4 smokes your 7.3 also. More horsies and torque, and it's a lot more than the 12 hp you like to throw out when quoting something you READ about the V10. (since again, you don't own one) If you don't know how a 6.4 handles, then you shouldn't act like you do. And before you try and say this thread is about the 7.3 vs a V10, you need to look at the title of it. It is the PSD vs V10 thread, which is all-inclusive.

 

You really need to read my messages before you reply to them. NOWHERE did I say the v10 redlines at 5200 rpm. It may make peak hp at 5200, but it still pulls strong to 6000. The drop off past peak hp to redline is a lot less on a gasser than it is on a diesel. You may turn 4,000 with yours, but I don't see why you would. If your 6.4 was even making a tiny bit of tq at 4,000 rpm then your peak hp would be at 4,000 rpm, not 3,000. Let do a little math here to show you. At 4,000 rpm if you were making 460 lbs of tq(~same as the v10) then your hp would be 460 x 4,000/5252= 350 hp. Your peak hp is 350. So even if you carry peak hp all the way to 4,000 rpm(which you don't even come close to doing) look at how sharply your tq drops off. At 3,000 rpm you are making 612 tq and in 1,000 rpm it has dropped to less than 460 at the MOST. You also need to remember that this isn't 6.4 vs v10, but it includes ALL psd's. Taking the average redline(or at least the useable redline) of all 3 psd's, it does come up to about half what a v10 is.

I don't own a v10, but I have driven them enough times to get an idea of how hard they pull. At my last job I had a 2v and a 3v v10 for a company work truck that I put quite a few miles on. I have only driven a 6.4 a few times, so I don't have a lot of miles behind the wheel of one, but you don't have to own a vehicle to have driven one and know how it handles. (By the way, I don't see a v10 sitting in your driveway either).

 

never did i say you were getting jp8 at the pump.


the "type" of diesel from wiki is "similar in composition to automotive diesel"


Outside of powering aircraft, JP-8 (or JP-5) is used as a fuel for heaters, stoves,[2] tanks,[3] by the U.S. military as a replacement for diesel fuel in the engines of nearly all tactical ground vehicles and electrical generators, and as a coolant in engines and some other aircraft components. The use of a single fuel greatly simplifies logistics.

 

Oh boy, I have a feeling I am about to jump out of an airplane and into the front lines of WWIII here, but here goes.
The Powerstroke diesel motors do indeed have more power and torque, and this makes it great for towing and hauling. The gassers, beit 5.4L, V10, whatever... all have their advantages too- mostly economical. It is a simple fact that diesels make more torque than gasoline engines, and that gasoline engines run higher RPMs that diesels. Wither it is gas or diesel, each have their own good points and bad points. Same can be said for breaking down each catagory. The 7.3L tends to be a stonger engine than the newer Powerstrokes, and the 6.0L/6.4L family produces more power and ability. This can be seen in countless comparison videos of the two. All in all, it breaks down into this. There is no general purpose truck. One should buy what best suits their needs, plain and simple.
If you want better fuel economy and an engine that will last a trip to the moon and back, or if you are not a stickler for maintenance, then get a 7.3L diesel.
If you are looking for low service cost, repair cost, and cheaper fuel, get a modular gasser.
If you are wanting the best towing ability, best available fuel mileage, and a quiet ride, then get a 6.0L or 6.4L.
If you plan to haul a bunch of people around, get a crew cab. If you want to haul a lot, get a long bed. If you don't want to have to park a long vehicle, get a short bed standard cab. It is all about what you need out of the truck and what is out there to buy. Deciding on V10, 7.3L, 6.0L, 6.4L, etc., is a lot like buying a single pair of shoes. You would not want to buy dress shoes to play basketball, any more than you would want to buy sneakers or bowling shoes to go with your wedding tuxedo.

 

welcome to FTE! the only advised i have for you on your v10 is get a psd lol. just kidding. im sure bill will be more than happy to hook you up with whatever info you need.

 

Welcome to the forums, and congrats on the new truck! Don't worry, maybe one day you will convince your dad to man up and buy a Ford.
It is sad when a child grows up in a dangerous and irresponsible family such as GM owners, and all too often that child will follow right along in the footsteps of their parents. They see their mom or dad descretely sneak into the garage and take the GM out (provided it starts up) and they think it is okay. Then when that child goes to high school, they too might be pressured into buying a GM product. "It's all good, everybody is buying one." they may taunt you. "Just drive it... just once. What's it gonna hurt?" they may say. They may look "cool" with their arm hanging out the window and their mullets flowing in the wind, but it is not all fun and games. It is refreshing to see a kid go against all odds to become a productive member of society and proudly sport the Blue Oval, and I for one applaud you. It is now up to you to break this cycle and teach your children and your children's children the drawbacks of GM ownership. If we are going to turn this country around... this world around, it is up to people like you to instill a sense of responsibility in the future of this planet. Remember, partents who drive Chevys have children who drive Chevys.

 

I agree. Forced induction is not nearly affected by air density as naturally aspirated engines.

 

Hey Tennessee....That's funny and yet very true. My 5 year old son already knows that Ford is better than GMC. Everytime we go to visit, he says...."Hey daddy, your truck is bigger and nicer than grandpa's"

I'm proud to be a new member of the Ford family and have already begun adding to my truck. I am very frustrated though with the lack of products available. Do you know if SCT, Bullydog, ie... will support 2009 V-10's? Their website doesn't show it. I suppose I will have to pick up the phone and call. Thanks for the support.

 

That is a good boy you have there! Props to you for raising him right.
To be honest, I am not sure about that, but I do know that Diablosport does a lot of stuff with Ford modular gasoline engines, might want to check them out. We use DS a lot on our Mustangs and would not hesitate to recommend them in a heartbeat. Good luck.

 

By the way, here is a link to some info on them.
Tuner Tools, the inside line: 99-05 Ford 5.4L & 6.8L Trucks & Vans DiabloSport Predator Tuner U7152, DiabloSport Predator & Power Puck, DS-U7152

I am all but positive that SCT does the 6.8L as well. Bullydog and Banks are more geared toward diesels, but might have something to offer the gassers too.

 

Actually the v10 has more power, but that is beside the point.... I don't argue for one bit that diesels don't tow the load easier. That is why virtually everything that is industrial uses a diesel. If you can do the same job at 2k rpm that it takes another engine 4k rpm to do, then chances are you are going to use less fuel and create less wear. However, I think the fuel mileage argument in favor of the diesel went out when they came out with the 6.0.....

My argument is on the "faster" part. It is always brought up that if diesels didn't tow better they wouldn't put them in semis or bulldozers. That is true. The same argument can be used for "faster" too. If diesels were faster don't you think we would see them in Nascar or nhra? Why don't we have diesel Mustangs? You build Mustangs and race too, so you should know the answer to this without even thinking. If you build a Mustang that makes 600 hp at 6k rpm, but you put a rev limiter on it at 3,000 rpm(where it makes 350 hp) and then you build a Mustang that makes 362 hp at 5,200 rpm and race them, which one is going to win? The one with the rev limiter(and less hp) is going to break your neck launching and have a lot more throttle response than the one with more hp, but the one with more hp is going to catch up and pass it pretty quickly once the other one runs out of rpm's and changes gears a couple of times.

 

Fact is, diesels have not been developed for racing in this country. But they are certainly capable. Have you watched the endurance racing in Europe, such as Le Mans? In recent years the diesels have dominated. We are talking 200mph + cars running 24 hrs.
