V10 vs psd

[mavrik4x4]

Jesus Christ!!!! Talk about 'Ask and ye shall recieve!"lol I was searching v10 vs PSD and I havnt even finished reading all the responses in this ONE thread!lol Im pretty sure I know what the conclusion was(somewhere amungst the 14,000 comments here in), was it something like... Different strokes for different folks?lol I was curious simply cuz I do NOT want the weight of a PSD on a 4wd that I USE, and you cant find a PSD with any less than 220,000 miles anymore. I dont want to have to work on one of those cramped up things!lol

600HP + 20K = breaking something.
485 would be about the max for a reliable work truck, IMO.

That's the good thing about a turbo. You can have a 600 hp engine when you're full throttle, but also have a very tame engine with great reliability under normal driving conditions. If you have a 20 psi turbo and are cruising at 60 mph at roughly 2k rpm you are using no more fuel and will have no more reliability issues than you would without the turbo. Where you will run into reliability issues is if you can't keep your foot out of the pedal. You just have to make sure you build your engine right beforehand with that kind of boost.

YOUR v10? I think my 5.4 would. It would be close though. A 3v 5.4, hands down yes. Neither mine nor the 3v is in the same ballpark as the PI 2v v10 or the 3v v10.

I cant keep my foot out of it, I would rather have less HP and be able to beat on it all day then have more and not be able to floor it all the time.

You have a PI 5.4 with 4.10s and a 6 speed, right?

If you can't keep your foot off the pedal then a lot of boost isn't for you. I'm just not sure if 4-5 psi would even make a difference though. But like I said, all of my turbo experience is on older engines and 4-5 psi on them was barely even noticeable.

Yeah, mine is a 2000 model, reg cab, 4.10 rear and 5 speed manual. My cousin used to have a non PI v10, ext cab, auto, 3.73 gears and I would out pull him all the time. Yours probably doesn't weigh as much as his, so it would make it a little closer.

What kind of trailer is dropping your mileage that low?

Any V10? Bill, I think you mean EVERY V10, and since we all know the V10 outpulls the PSD, we won't even include them in the comparison.

[ruschejj]

Pinky: I use 3 trailers for work, a 16ft, a 20ft, and a 36ft fifth wheel. I get around 10mpg with the 16 footer. Usually only weighs around 6K filled with gear. The 20 footer gets into the 10K range. Enough to get your attention but I still get 9-10 mpg with it. The 36 footer is also a cargo trailer with a lower profile and "V" nose so it's better than a camper to tow. Triple 7K axles and I run anywhere from 13K to 16K with it. This is when I dip into the 8's for MPG.

My MPG's are all calculated with interstate driving for the most part. You know, drive 220 miles at 72 mph.

I used to run with a Chev. 3500 duramax and also a Chev 8.1 gasser. Pretty much the same mileage. The gasser would dip into the 5-6 MPG range, duramax was 11-13. The 6.4 is the best motor I have run with but the pre2007 duramax was the best on MPG. Same as the 6.0 would have been, not as good as the 7.3 would have been.

Only if your 5.4 has a supercharger or Nitrous.

The post I was referring to was discussing fuel consumption at idle. When I'm idling I'm not going anywhere so it's 0 MPGs.

Good thinking on fuel consumption while running, though. 6 MPG is on the low side of normal.

I like the power of the new diesels, but I'll never buy one for long distance towing because of the mpg's you list here. I pull a 24 footer(8k lbs) from Kingsport, TN to Dayton, OH a lot and I get 19 mpg doing 65 mph. The 6.0 and 6.4 won't even get that kind of mileage completely empty. They will pull circles around me in a shootout type run, but that's a situation I will never encounter on my trips.

Have you driven a 6.0? I ain't gonna argue with ya cause you are on the PSD side. LOL But mine prior to the EGR/Exhaust/tuner would get 17 doing 80/85, hand calculated. So it is logical it would get 19 or 20 at 65. I have gotten 17 hand calculated with 2 hours at 65, a few days around town, then 2 hours home at 65. But I have not burned a full tank at 65mph, would take a long time! haha. (though I will say I did only get 13.5 recently into a bad head wind at 85 with winter fuel, after the mods.)

Now after the mods, I am not sure. We are on winter fuel up here, which hurts a little. But I would take the 6.0 out of that statement. (Though there are very legit arguments against reliability)

[bill11012]

Phillips,I have driven a PI 5.4 with an auto and 3.73s, it was not even close to my V10.
With the ZF, I bet you would out pull me from a stop.

If we both started a hill at speed I would hold my speed longer.

If I had the the stick I know I would out pull you, but I just can not get off the line with a load.
The final drive ratio in first on my 4R100 feels like I am starting in second gear.

BTW, With the tools I carry with me it weighs 7,600 pounds.
So if anything Weight would give me a disadvantage.

You get that towing? He is talking about 8K behind him.

There is a lot to be said for a smaller purchase price, especially if you don't put too many miles on it... or are comparing it to the mileage of a 6.0 or 6.4...

:-) I'm biased in the opposite direction, despite my decreasing budget. The home town I grew up in is listed as being the single city most likely to get you killed in an auto collision. (Lots of idiot teenagers, and even more retirees that can't see, can't turn their heads to look, don't look even when they can, don't look where they're going and more often than you'd believe... don't even remember which side of the street they should be driving on. I watched one cause an accident when she ran a stop sign... only to jump out of her Caddy and begin yelling "I was here first!")

That being the case, I swore I'd never drive anything that wasn't nimble enough to get out of the way, powerful enough to take a hit. While these trucks will never be nimble, I've lost count of the times that having that little bit of extra power, especially towing, saved a call to the insurance company. (Yes, there was one time when someone pulled out in front of the loaded truck that more power didn't do much for anyone.... but that's entirely beside the point.)

When I was younger (and broker) I owned a little 4cy pickup. It was next to indestructible (we tried) but it couldn't get out of it's own way... especially towing. Two Jet Ski's with full tanks and a cooler in the bed left me with a 0-60 of just under a couple minutes, leaving me at the mercy of whatever idiot happened to be driving nearby. (The 'pucker' factor far outweighed any savings in mileage.)

In all fairness though, I'm biased... and can't stand the thought of being left to the mercy of the idiots around me. If something bad happens, I'd kinda rather it be my own fault.

I do love me some 7.3

Edit: Hey Mavric... welcome to the thread. Seems like quite a few of the people that find their way here become regulars. Apparently Bill's charm is irresistible.

Look guys, I aint gonna lie, I didn't read a single damn post of this thread other than the title as it seems to be a very popular ongoing debate... that wont die.

But my $.02 is, I said it once and here it is again:

(Us gassers)

We dont need none of this EGT, particulate filter, ULSD, regeneration, glow plugs, faulty injectors, expensive oil changes, water in fuel, masking off our front end because our trucks are afraid of the cold, intercoolers, dual batteries, or any of that other oil burner voodoo.

Last but not least, any of you diesel guys cannot argue this one... my vacuum pump is not only bigger than yours-- but makes 260 horse out of the box Now thats how you really please a lady... and when she's done having fun with it, she won't smell like an oil refinery
