Buying a new Truck

[jejeosborne]

I've bought an '11 EB 150, and love it, so I've followed this thread from the start and still not sure where my fellow Granite stater Dmace stands.

Is he a EB supporter or a Dodge lover?

Just not sure......

Just wait until you get those dreaded air leaks that take a week to find like I will. LOL

I bet you are one of those guys who ranted about having to spend $8,000 on new batteries for the Prius after a few years. I doesn't happen and they have been out for over a decade. Last I checked no consumer has ever had to buy a battery pack. I assume Toyota covered the few that failed.

Odds are better than you think, rubber hoses get worn, plastic fittings break and weather deteriorates clamps. As far as "less cramped than any vehicle I have recently owned", well it's not as open as anything I've owned. Have you been driving vans...?

Again, it's not "diesel like". "Diesel like" to me is making near max power at low rpms, a little comparison:
A Cummins diesel makes 100% of it's 800 lb.ft. torque at just 1600 rpms.

The HEMI makes 80% at 1500 rpms. 2012 Ram 1500 Powertrain | Improved Engine & Transmission | Ram Trucks
Ecoboost only makes about 60% at 1500 rpms.
Ford V8 5.0l makes 77% at about 1500 rpms. How We Dyno Tested Ford's 3.5-liter EcoBoost V-6 and 5.0-liter V-8 Engines - PickupTrucks.com News
Not so "diesel like" is it...

Yes I have only owned vans in the past. About 10 screws and 2 minutes and all that plastic is out of my way when needed. Have fun replacing your 16 spark plugs.

Your eyes must be going, look at the dyno sheet you posted again. The ecoboost makes approximately 375 of its 420 lbft of torque at 1500 rpms. That is 89 % on my calculator. Peak torque takes place at 2500 rpms. **** good enough to call it diesel like to me. Your Hemi peaks at 4000 rpms. Why are you touting about how great the 5.0 liter is after this comparison? Talk about a peaky torque curve...the ecoboost keeps over 90% between 1700-5000 rpms. Lets see a diesel do that!

Now lets look at the 2000 rpm range.
Hemi 84%
Ecoboost 98%

How many extra revs that Hemi going to have to make to get anything done?
As diesel like as any gas motor I have ever seen. Please post any other truck gas engine you know of that makes 98% of its peak torque at 2000 rpms. I can't think of any can you?

Looks like a van engine compartment to me. It appears to be less crowded than the engine compartment on my parents '99 E350 with the 7.3 Powerstroke.
IIRC, it is about the same as the vans that the hotel I worked for had (they had 3 E350s and 2 Chevrolet Express 3500s. All were 15 passenger vans from the '04 or '05 model year and all had V8 engines).

As has been said, a few screws and a 5 minutes will get most of that plastic out of the way.

The 454 GM of the 90's had over 400 ft lbs from 1600-4200 rpm, 405 at 1700 seems a bit more diesel like to me than these newer engines. However it's very impressive what they've done with a 3.5 liter, but remember supercharging in effect creates displacement on demand and when you demand it it will use the fuel same as a large engine or worse, as shown by the towing mpg of the Eco Boost.

Would love to see the graph. I agree about the volumetric efficiency improvement as needed. I only need it about 10% of the time.

 

[toppop52]

Here's a chart for the old one, it had 380 ft lbs at 1400 rpm! That's pretty impressive as well;

I can't find a good Vortec chart, but looking back I think I was referring to the 8100, not 7400, the 8100 actually gets better specific mpg than the 7400, has 455 ft lbs at 3200 and makes 90% + of it's torque from 1200 rpm through 4000 rpm.

Well, I take responsibility for not being more specific in my request. I should have mentioned the engine must produce respectable values as well. That is a sad excuse for power vs displacement in an engine in today's world. I agree the shape of the curve is flat but it is easy to produce a flat torque curve with little torque. For example, an engine could make 100% torque through an rpm range if it's peak level is weak. Say the ecoboost peaking at 300 lbft would have a flat curve from idle to redline.

 

[toppop52]

455 ft lbs in an engine of 496 cubic inches, with 90% available below that in an engine from 12 years ago is really not weak. and a flat torque curve, even at slightly lower peak is far preferable for towing and hauling than big numbers in a narrow band. My point was, the Eco Boost is no more diesel like than several other gas engines of days long past. That graph is of an engine first available in 1987, not the 8100.

lets look at the numbers;

50,000 miles @ 15mpg = 3333 gallons @ $5/gal = $16,667
50,000 miles @ 19mpg = 2632 gallons @ $5/gal = $13,158

I'll risk it for $3,500, especially since they tested the snot out of this engine.

If this was going to be a super low mile vehicle, then no, I wouldn't risk it either. heck, I went out of my way to get a V10 for the farm truck, but it replaced a vehicle that averaged less than 2,000 miles a year.

If I start hearing stories about them munching turbos or what have you down the line, I'd use my fuel savings money to get a new truck sooner than I would otherwise.

I don't recall mentioning battery packs...And yes I'll gladly pay the additional fuel cost, I knew full well what the mileage would be when I bought my 6.2..I also drive it at least 30K per year and I have no complaints..
