yeah, neither can they....lol

 

If they brought the hemi up to 25mpg, what would be the point in owning a V-6. Only thing i could see out of that is, the overall price between the two trucks. Most people in the truck market want the power over the economy, (most people by trucks for towing and work) especially when mpg`s are so close between the two, most people are going to choose the hemi. Dunno, but i do know that i would never buy one of these V-6 trucks.

 

8sp Manual in the Hemi? Thundering crickets, if that was not a typo, Than I'm sold.
I thought the 8speeds were going to be automatics?

Fords eco fryer is really fun to drive, thiers power thier, but, the trend to put smaller higher hp engines in trucks that are just as heavy as a V/8 powerd truck is not making sense to me, two extra cylinders is a far better option than two turbos and im impresssed with the new 5.0 ford truck engine thats a bought a grand cheaper than the ecobost.

Are the new hemis still running copper plugs?

 

I'm not one to bash a turbo charger, but as another poster said in Fords situation it is like they are replacing two cylinders with two turbos. Turbos are fine if you know how to properly use them, and if the truck is built with that in mind. Most of us here know you can't just throw a dual turbo setup on, tuner, headers etc: Without making sure the rest of the motor/truck can handle it. IMO it just seemed like Ford threw the turbos on to bring up the HP and make it closer to the V8 power to make it sell-able. Now that dodge has done the same thing, without the turbos it will make it a more reliable motor.

As I said if you know how to drive a vehicle with a turbo then you won't have issues. But lets face it, many people out there don't know how. I see WAY to many people, turbo-diesels even the diesel cars, run them hard then shut them off. KILLER to a turbo! Have to let it cool down after running it hard. Now I am not saying 5 minutes of course, but enough to let it cool to the point of not hurting it. Also the same on spool up. I am sure if you look at half the issues with turbos is for the simple fact the driver is unaware of how to do it. Which will hurt a company from a warranty standpoint.

 

I guess Ford isn't too worried about the warranty on the turbo's. They're too busy dealing with the transmission in those trucks to be worried about anything else..

I think one of their selling points was V8 power with V6 fuel economy, maybe Ford can't engineer good mileage our of their V8's? I don't know what their new V8's are capable of mileage wise...

 

Why? I don't get it, everyone says this. Turbo's aren't known weak points in turbocharged applications (forget the sooting of 6.0L Powerstroke and 6.7 Cummins...the emissions systems are to blame there).

 

As I stated above, not everyone knows how to properly drive a vehicle with one. The killer of turbos is heat, and if you don't let it cool down or warm up before working it hard. In time its gonna go.

We don't see it happen too often with diesels (besides those with filters) Normally because people know to warm up a diesel, in turn will allow the turbo to work properly.

When you put it on a gasoline engine however, people just stop and go with them. They get in and go, (not counting cold temps) Now to have this same setup in a truck where if your pulling its gonna be working them, more so being they are taking the weight of two less cylinders. I know many people who once they are at their destination they just shut off the motor. No cooldowns, which means bad for the turbos.

If anyone knows here, if you look at a turbo after its been working it is glowing red. To shut it off right away and let it air cool is soo hard on it. Let it spin at idle and allow the temp to cool slowly. Some people I know have turbo timers. So even tho the key is turned off the motor still runs till the turbo reaches a set temperature.

Again I am not saying turbos are bad, but without any knowledge of how they work, they are going to cause issues. Especially on a gasoline truck with two less cylinders. I have heard several cases of turbos being replaced on the ecoboost at around 50k kms. Pretty bad if you ask me. This is why I am glad that the pentistar is not turboed. More reliable to the general public.

 

Whether we like it or not, the Feds mandated higher MPG for the fleets so ALL of the manufacturers will be going to V6 engines with turbos. I think that GM and Chrysler will be first with the direct injected V6 diesel Turbos on the trucks.

Another thing, don't get your hopes up for the Hemi getting 25 MPG on the highway unless you drive like an 80 year old asian (funny, not mean OK). The eight speed adds gears on the low end and changes the first OD but the final OD remains the same. Here are the 8 speed ratios in order, 4.71, 3.14, 2.10, 1.67, 1.29, 1, .84, & .67. The 6 speed is 3, 1.67, 1.5, 1, .75 & .67. So looking at the difference, the Ram will get off the gate really fast and when driving on the highway, the .84 OD will be more useful than the .75, especially when towing, it won't have to downshift as ofter on hills. Another thing, with the 5th gear at 1.29, versus the 1.5, the Ram will downshift really nicely. To me the eight speed with the 3.55 gears and the 17" wheels will be a hell of a truck.

 

Higher MPG for sure is mandated, stupid environmental agencies :P However adding a turbo will not necessarily do just that. Obviously according to the "stats" of the pentistar, they have achieved just that. No turbos on those, I am still trying to figure out how to accomplished that tho...
As far as I know the cummins is already direct injected 6 cylinder, its just a inline...I thought thats how the power of a diesel was created?

 

Cummins has always been direct injection, Ford went DI in 94 with the 7.3 Powerstroke, GM went DI...hmm I'm not real sure. Pretty sure the 6.5 is DI, the 6.2 may be as well?
