dodge goof

[TORQUED]

Did you know that Dodge is short changing the 2003 owners. Chevy and Ford diesels have the varible geometry turbos and the Dodge version of the ISBe doesn't. More turbo lag may not bother most but did you know that the VGT also doubles as a exaust brake. (Pac brake $900) At least Dodge could offer it as a $??? option. When Dodge offers this and rear wheel steer I will trade off my 99. Has any one heard of this.

VGT

Yes I know. Cummins has the VGT and should be available over the parts counter. We got screwed again. I still love the truck. TBOB

How can a turbo act as an exhast brake?

 

[Steve M]

Rear wheel steering and VG turbochargers? The simplicity of the Cummins is it's main attraction. I don't desire rear wheel steering either. It's perfect as is in my beedy little eyes.

 

[Steve M]

Oops. The VG turbocharger has a circumference of variable fins in the housing that change pitch to increase or decrease flow and turbo output. The result is less turbo lag and the ability to restrict exhaust for limited exhaust brake like backpressure. I have a hard time imagining a long trouble free turbo life with all those vanes connected with linkage operating in diesel exhaust. An exhaust brake is the epitome of simplicity in comparison.

Vgs seem like they might be a little fragile for the performance boys.

Screwed again??

I don't feel like I was "screwed". And there is certainly no turbo lag evident in my beast. The VG turbo is being added to engines that have enhanced emmissions packages. To me that indicates it is there to make up for a problem created elsewhere. The ability to restrict the exhaust flow is simply a side effect to the design. I am happy with what I have. Just my two cents.

VGT is definitely the future of turbocharging. Its a great concept, and will likely help us performance boys in the long run. However, the current run of variable vein turbochargers are not as reliable as the manufacturers would lead us to believe. The Holset VGT in use on the bigger trucks has a fairly poor reliability record (reports from the heavy diesel industry). Personally, I'll be happy to stick with a B1 or K40 until all the bugs are worked out of the VGTs...

the holset version of the vg turbo is simpler than the one that navistar uses in their vg365 [psd g2] from the literature that i have seen the holset ones has a collar that slides over the larger part of the turbine and extends from the center section towards the turbine outlet. the collar makes the passage for the exhaust smaller, increaseing the exhaust manifold pressure forcing it through that smaller space under higher velosity. as boost/drive pressure builds, it opens up the collar and decreases the drive pressure. there is a video on the cummins website showing how the turbo works...

Rear steer, you are kidding right ? It's more like something for yuppies that don't know how to drive a truck.



It has no place at all on a tow truck in my mind. Have you seen the GM version of this, their is a reason it is only in a 1/2 ton, it is very fragile looking. 4 Wheel magazine proved this when they broke the one they tested LOL.



Could you imagine a rear steer dually, that would be a site.

The VGT is coming but it is bringing EGR with it, these two items

are part of the next great emissions package.

Hello, all !

I purchased a 1990 Dodge Daytona Shelby new in March of 1990. This particular car was equipped with the "Turbo III" engine--some of you die-hard FWD Dodge Motorheads may remember these... . basically a 2. 2L sequentially multi-point fuel injected intercooled turbo engine with their VNT Turbo. The Variable Nozzle Turbo had adjustable vanes that WORKED... according to Ma Dodge, the VNT engine built full boost at 2. 3 seconds, as opposed to the 4. 5 seconds of the non VNT Turbo. 174 HP in this car was awesome, and with some mods, the car was as quick as some stock GM Camaros and Firebirds thru the quarter. {Gosh I miss that car, but I LOVE my truck} As far as four wheel steering---as soon as they put it on over the road tractors, maybe I'll see the need for it. Otherwise, it's just more ***** to tear up. I work at an S&S Tire in Lexington, KY and we see lots of GM 1500 trucks, Tahoes, Suburbans, Denalis, Yukons, etc with worn front end parts at 40K to 50K miles---idler arm, pitman arm, lower ball joints, and usually upper ball joints. I could see the repair bill mounting on all of the previously mentioned parts PLUS rear wheel steering parts, too. Excuse the rambling---just my $. 02 worth... ... .

I don't see how you guys think 4 wheel steering is bad. Tighter turning radius, improved cornering, and lane changing on the highway. All GM's with the quadra steer use the dana 60. I agree the tirods are small and the 4 wheeler test did damage one. Even after breaking it they still agreed it was worth having.

 

[krohn]

You would use that to change lanes on the highway?!?!?! Can you even use it above a certain speed?? Four whell steer to me is just useless. I guess I dont see a purpose for it unless I was city-slicker that didnt know how to drive. My $. 02

 

[Badunit]

Four wheel steering turns the rear wheels one way at slow speeds and the other at high speed. At highway speeds you crab over into the next lane. Imagine doing a quick lane change: the rear end will glide on over with you rather than fishtail. Sounds pretty nice to me.



I don't know what these yuppies and city slickers not knowing how to drive comments are about. Maybe out in the wide open country where the land is cheap and the parking lots have large spaces and wide travel lanes it's easy to park a truck but in the city and in suburbia, land is at a premium and the parking lots are squeezed tight with small spots and narrow travel lanes. I've seen plenty of places where you can barely back a full size truck all the way out of a parking spot (and a few where you truly can't). So maybe four wheel steering is not necessary in the country but it would be handy in the city and in suburbia regardless of ones driving ability.



Disclaimer: None of the above ranting is an endorsement for GM or their system. I like the concept of 4-wheel steering but their system looks a little weak to me.

 

[JoeyD]

Even a Hill Billy could benifit from 4 wheel steering.

Every store, bank or anywhere has parking spots that you must park in which requires turning the wheel to get in there, this would make it easier.

 

[lschultz]

I don't need it. If the parking lots are too crowded and its too much trouble to get in that space that is close to the door just go to the end where nobody parks cause they don't want to walk and park and walk. Thats what your two feet are far. Then you don't have some idiot parking close to you and banging there doors on your car/truck.

 

[Steve M]

I live in a very crowded area between two cities. My long bad quad cab is a bear to park in some places. Most of the time I back into a spot if it's allowed. It's easier to back in than back out. I want no part of four wheel steering. If it becomes an option, those who want it, go for it. Those of us who don't, don't...

Next year we'll be getting the EGR valve and VGT. However we'll still be better off than the new and unproven 6. 0 PSD. The PSD has it's crankcase venting into the intake after the air filter and before the turbo. An over oiled K&N will be pale in comparison to a used oil mist being fed into the turbo charger and intercooler and on to the intake with it's sensors. Our crankcase will still vent to the filter on top of the engine like the '03. If anything, I would have thought Ford would vent it to the clean side of the filter so you could capture the mist in the filter and buy a new one for $92. 00 when it's dirty.

The Daytona Turbo with a VNT turbocharger was a T-IV not a T-III. The T-III had a DOHC 16 valve head and made 224bhp stock.



The VNT's were sweet for *leave it alone* performance. They didn't work well in higher-performance applications, they were to restrictive on the turbine side.



Also, they could be failure prone related.

I for one like the concept of 4 wheel steering. I drive trucks around a very crowded lot I have to fold the towing mirrors in to get past some spots alot of fun with a dually getting the hips past that spot. I've had times it's taken 10 plus minutes to get a truck into or out of a parking space. At times I've had problems getting a neon into and out of a spot then have to pull a dually into that spot.



Now look where 4 wheel steering is used fire trucks at least the ladder trucks often have rear wheel steering though they normally have a second driver to control the rear. Monster trucks use it ect. Yes there are other things I would like to see them do before adding 4 wheel steering like allowing the front wheels turn 50 degrees put better mirrors on everything not just the trucks why they insist on putting the smallest mirror they can find on a car instead of one that works is beyond me and all side view mirrors should be power. If they desighn the 4 wheel steering correctly I want it.
