Upper RPM limits on HPCR ??

When I asked this question when I owned my '02, I got the same answere from Cummins and TDR, 2600 rpms is the highest I would want to sustain for long a period. I also understood that it was the VP44 that was part of the problem with sustaining high rpms.

So what is the upper limit of sustainable rpms with HPCR ???

In my uneducated mind I don't think the CP3 would care very much what the rpms are. And I would think that electronic injectors should be able to fire faster than the VP44 fired the injectors.

As long as my temps are within limits, would it cause any problems to hold 2800-2900 rpms in 4th gear ( NV4500 ) for say 10 min. ???

TIA

Jeff
