Just curious since the weather is so cold.

On the 6. 7 with the e-bake integrated with the turbo, does this system still work at idle like the Jacobs to help warmup the engine?

The Jacobs blocks the exhaust, but with the VVT on the 6. 7 will it accomplish the same thing at idle? If so, would it be as efficient as the Jacobs?
 
The Jacobs takes it commands from the ECM for exhaust brake function at warm up, if the ECM has been programed for this function I'm sure it will work. We need to ask someone with the new motor and the exhaust brake feature to answer this for us...

The following quoted from the Texas State fair Sept 28 2006 press release!



"First-ever Optional Exhaust Brake



For the first time in a Dodge Ram Heavy Duty truck, an integrated exhaust brake is available direct from the factory. Utilizing the 6. 7-liter Cummins turbo-diesel engine's new turbocharger, the exhaust brake significantly improves control when towing heavy applications, such as pulling RV fifth wheels and horse trailers, providing added control and brake savings by transforming horsepower into braking power.



"Towing and hauling capability is critical for our customers, as more than 90 percent of Dodge Ram Heavy Duty customers tow with their truck," said Kunselman.



Benefits of the exhaust brake include:

* Increased vehicle control to provide the owner additional peace of mind

when towing

* Enhanced safety by reducing overheating and fading of brakes on

downhill grades

* Lower cost of ownership, extending brake life by as much as three times

* Capability for faster cold-weather cab warming



The 2007 Dodge Ram Heavy Duty's 6. 7-liter Cummins turbo-diesel engine's VGT is capable of creating the maximum exhaust restriction through a wide range of operating speeds, improving braking performance at low and high engine speeds. Testing has shown more than a 30 percent improvement in retarding torque at 2000 rpm compared with traditional brake exhaust methods. "

Well, I guess that answers the question. I just hope that the VVT doesn't suffer from the same issues as the one in 6. 0 :eek:

Thanks for the info.
 
the holset desin is far superior then the garret turbocharger that is found on th 6. 0l navistar engine. so sticking vanes here folks! the the electronic actuators are reliable and very responsive.

My '07 C&C has the EB feature and yes it works while idling when cold. The RPMs also ramp up to help with warm up. The turbo is very responsive compaired to my '99. I've only got 3100 mi. on it ,but am very happy so far.
