Don't know if this has already been discussed and seen? Here's a look at some changes to the new 610 lb-ft 2005 CTD.

The New Wastegate Turbocharger. 



 The new Cummins-powered Dodge Ram Heavy Duty 610 relies on a new Holset turbocharger to help deliver its industry-leading performance. The 5. 9-liter Cummins 610 is fitted with the Holset HE351 turbocharger which allows the engine to deliver more power and more torque than before. The new Cummins 610 generates its peak torque of 610 lb-ft at 1600 rpm, earlier than competitive diesels. 

The 610’s turbocharger delivers more power and torque than previous models despite

having the same envelope size. It is also the first Holset turbocharger to utilize compressor cover-mounted “command valve” wastegate technology which provides an additional degree of control sophistication. Wastegate turbochargers are matched to give good performance at low engine speed with the valve closed. The command valve enables override of conventional boost air-controlled actuation for even better control, improved transient response and reduced exhaust temperatures and emissions. 

The new Holset MY04. 5 turbocharger is being manufactured at both Holset's U. K. plant and its Charleston, S. C. , facility.

Neat info.

Could you put one of these new Turbos on an 03 305/555 or does it require the new 600 electronics? More realisitic to install twin Turbos I'm sure.

CTD 600 · Nov 5, 2004

So the difference between the 04. 5 and the 05MY is a compressor cover mounted command valve... Will it really make that much of difference??

jwilliams3 · Nov 6, 2004

Not only a command valve but an hx40 sized compressor.

Yeah, it makes a difference.

I',m pretty sure the turbos are the same on the 04. 5 and 05.

Ye Ha my 05 is due to be built next wed 11-10-04. Should have the new turbo and the old 6 speed trans. 05 4x4 quad sb 6 speed 4. 10 flame red. Hope to have by thanksgiving. Will keep exact milage data and post.

Gwoody,

Yeah, they are the same.

But the difference in the 03 and 04 turbos from the 04. 5-05 turbos is compressor size also.

So does my 04. 5 have this turbo? HP is rated at 600, not 610 as stated above. I think I will have to have a look under the hood tomorrow.

Yes the 04. 5 and 05's have this turbo.
