This is a short blog taken from a a couple of sources....all of which contained the same information and are very reliable as they are all end users of some sort of Cummins engine. NOTE: ISB ratings are in bold and read 325/750

Not sure if this has been posted as of yet, but i found it quite interesting.


The Cummins Particulate Filter and crankcase ventilation system are fully integrated with the engine to meet 2007 emissions standards. The Fleetguard® Enviroguard™ coalescing filter captures and filters crankcase emissions. Cummins is the only engine company with the key in-house technologies that enable the engine and aftertreatment system to be totally integrated for optimal reliability, performance, fuel efficiency and low cost of ownership. Both the engine and aftertreatment are controlled by a single ECM (Electronic Control Module).

The entire Cummins MidRange line will continue to use High Pressure Common Rail fuel systems - enhanced for 2007 with higher injection pressures to optimize fuel economy and increase performance. All engines will use the patented sliding-nozzle Variable Geometry Turbocharger (VG Turbo), which doubles as an exhaust brake with increased braking power in 2007. Also new in 2007, the VG Turbo features a new electric actuator with faster response and improved precision in adjusting airflow to the engine.

The ISB for 2007 will see displacement increase from 5.9 L to 6.7 L, providing more horsepower, more torque and, more importantly, more performance for customers. Enhanced electronic engine controls will increase the number of injection events per combustion cycle, so the ISB will continue its position as the fuel economy leader with the lowest total cost of ownership in its class. An automatic Oil Level Sensor option eliminates the need for daily oil level checks. And, a new 18-quart oil pan option allows for standard oil drain intervals to be increased to 20,000 miles (32,000 km).

The ISL, ISC and ISB all share an enhanced ECM with greater speed, memory and flexibility. The ISL and ISC both offer an optional compression brake.
Enhanced top horsepower/torque ratings for 2007 include: ISL 365/1250 (272 kW/1695 Nm); ISC 330/1000 (246 kW/1356 Nm); ISB 325/750 (242 kW/1117 Nm).
Customers will continue to benefit from Cummins superior ability to integrate critical subsystems for total performance and low cost of ownership. For 2007, fuel consumption and maintenance intervals are unchanged.

 

18 qts of oil!! ****- one expensive oil change with amsoil!

 

I think this has been posted before. Those are the industrial ratings. Our trucks will not have that much torque. Or I could be wrong. I just remember the ISB ratings for industrial were like 275hp/660tq and the same engine for our truck is rated at 325hp/610tq. Of course there are all diffirent apps for these engines so both numbers vary greatly.

 

Yep, these are not the numbers for the ISB to be used in the Dodge trucks, CC or HD. While most of the features here will be in use there will be minor differences and of course programming.

I just bumped my other post that I posted back in April that has some information in it about the 2007 models, including the HP/TQ numbers.
