Diesel P/U Longevity

[Egon]

It's the pressure involved. The big turbo takes a volume of air to a smaller volume. The next turbo takes that smaller volume and makes it even smaller. Its all about pressure differential across the turbo.

Just consider each turbo a stage in the commpression process.

To me I just think the OEM pickup manufacturers are gong overboard with this, now.

Seriously, what are you going to do with 900 ft. /lb. of troque?? My Cummins is at 175 hp and 475 ft/lb and it will haul anything I want it to. More power means heavier axles, driveline, springs, ect. If you need all this, you don't need a pickup anymore, you need a 2-5 ton TRUCK.

I presented that point a couple of weeks ago.. "maybe we should offer a couple HP/TQ options like the big rigs"... But I believe it fell on deaf ears...

The reason for this drive is not only for the race guys that must have the highest HP/TQ deisel on the block, but also for the guys that dont want to go though the extra cost of a F-650 class truck that they would need different licensing and insurance for.. Its a huge market for "hot-shoters" that transport cars and other stuff across the country.. These guys make their proffit by keeping the costs down with a smaller tuck than they should be using..

I'd say a lot of the increasing HP is politics of car companies. The old "race on sunday, sell on monday" mentality. One can advertise they have the most power in a xyz sized truck.

My F350 has similar power numbers to Aver8s and I'm sure I could pull more than I could stop quickly.

Very true... As a matter of fact thats been a problem for many years...Todays diesels are far more powerful than most people realize.. They make easy work out of heavy jobs.. They can do much more than the chassis is able to withstand over the long haul..

Can you really have a truck that is too powerful---if it does not break anything????

I just pulled my 24' trailer up I-77 through the mountains of VA and WVA. I was loaded at 12,500# and cruised right up through there. I worry more about an emergency stop than anything else. I am a real stickler for keeping my trailer brakes and tires tip top. Also, always maintain lots of room between me and the guy in front. I can't believe some of the idiots I see out there right up someones tailpipe while pulling a monster trailer. There is no way in the world they are going to whoa that thing down in an emergency. Those are the Bozo's you see jack knifed in the median scratching their head.

John, since my wife was from Princeton, WV, I've driven that I-77 many, many times, sometimes just in a car or pickup, a few times pulling our 32' fifth-wheel, and a few times when we had a 40' Bounder motorhome. On one trip in the motorhome, we had to stop in traffic for about an hour while they cleared away the wreckage. Two women and 3 kids in a van pulling a pop-up tent trailer and the trailer got to fishtailing going downhill and she lost control and wrecked the entire rig. I know it killed one of the kids and I never heard whether the others survived or not.

John,

Yes I have seen those folks also. I suppose that IS an advantage of the new Ford brand trucks, with the electronic trailer brake controller. It really does seem to help control loads. I myself do not pull often with my pickup, but when I do it is usually close to the max trailer weight doing so. I personally have found the extra power most beneficial when merging, or maintaining speed when pulling long grades with a load. I have also found that I can tow even uphill in overdrive when some others have to shift to a lower gear. My opinion on the new horsepower wars in pickups is yes, it is oneupsmanship, but these trucks are also delving into areas of engineering not previously seen. Things such as electronic brake controllers, multiple speed trannies, etc.

I started driving diesel pickups in '82 when I bought a new GMC with the 6.2 diesel. There is NO COMPARISON between the first diesels and the ones available now. The 6.2 in the GMC had 130 hp and about 240 lb/ft torque with a 3 sp auto. My '04 F-350 with the 6.0 PowerStroke makes 325 hp and 560 #/ft of torque. Yes, it's a much more complicated engine with the electronics but there is no way I would ever want the old engines again. Except for the 220 Cummins in my '59 White!
