Cummins goes to 1075 lb-ft

[GirchyGirchy]

All fine and dandy...but did they upgrade the fuel pump for '21?

It will be a CP3.

It will be a CP3.

You want it to be a CP3, or you read it would be a CP3?

Neither - I know it will be a CP3.

Any documentation of this???

Just a higher number to be wiped out through Torque Management. I'll take an 8-10 speed transmission over the TQ bumps.

 

[Ltngdrvr]

Well... My last 18 wheeler had a Cummins with 1850 ft.lbs. TQ running through a 18 speed trans. Of course that was a 15 liter engine.
Give me that much power in my next pickup!!!

 

[GirchyGirchy]

430 HP to go with the 1075 ft-lb, too.

I like the inverter option. That would be a really handy deal.

No mention of transmission options either.

I wish I had an inverter in the bed... or atleast more than 150 watts... I wonder if I can upgrade to a 19+ inverter capable of 400 watts.

Should be easy enough to add your own aftermarket one. Put it closer to the batteries so the long run to the bed is AC and not DC.

I could most definitely do that, but I wouldn't go through the effort for that. It just doesn't seem worth it. But if the "newer, 400 watt" inverter was plug n play, I most definitely would lol.

No, it's still 400 - see the official spec sheet.

I'd be interested to see the torque curve. It was flat as a table top. Must be a little convex now? Or tails off a bit more?

 

[TFucili]

Hmmmm, there seems to be some corn-fusion. The Ram web site shows the 430 HP number...

And the same two transmission choices, slip and slam

Not sure why Cummins quit posting power cubes, used to be great info and reinforced our support of straight 6 diesels.

I'm still a fan of Ram and Cummins and am impressed with their offerings. Heck, I'm still impressed as hell with my 17 Ram 5500. 4.88s almost give it a sports car acceleration and performance, like a frisky mule

Anyhoo, Viva Ram and Cummins.

Cheers, Ron

I’d guess it’s because they are no longer flat torque curves, so not as good for marketing.

Assuming they were flat the motor would need to make 511hp at 2500 rpms to have 1075 lb/ft, and 615 hp to carry 1075 thru 3000.

Assuming a 2800 to rating on the 430hp that’s still 806 lb/ft and nothing to complain about.

Also, while they don't have as flat a curve as the Cummins, Ford's peak torque RPM is at least as low as the Cummins now. I still prefer the I-6, but the V-8s have closed the gap, and still have 1K more RPM to work with. Not my cup of tea, but I'll give credit where it's due.

With their higher horsepower rating I would bet they have a flatter torque curve. HPCR has done good things for the V8's...but I still prefer I6 for actual operation.

I don't hear much of anything about the Maxi-pad anymore, is it dead ?, or is it GM is tired of having to repair diesels.
