Holset Variable Geometry Turbo

[JohnE]

The HX-40 on the <b>ISC</b> already has an integral coolant jacket. In fact, the outlet from the turbo is also a vent line when filling the system. It prevents an air bubble from holding in the water pump vanes.



I'm curious if a VGT turbo will be part of the new emission ISC coming in 2002. Detroit Diesel has the Garrett VGT turbo on the Series 50. The Series 50 is now only available with cooled EGR, too. I hear the new ISC will also have cooled EGR.



I'll keeping digging for more info, too.

Come on now..... Who would want a purple and green turbo on their truck? Two radiators and a humped hood. The 2003 Ram!



Might be.

did anybody catch the turbo on that diesel....

Did anybody see that article on the new isb in the latest edition of North American Diesel Progress? It said that the new isb will have one of these. Now it said that this was the bus version but still none the less, this will be the turbo on the next Ram Diesel.



The article also said 275 was the highest hp rating while 660 ft-lbs. I think that they will put a different ECM program in it, how bout you?

With the information that we've dug up on the turbos both models (40 & 55) are electronically controlled. But not with a couple of wires carrying an analog signal, they actually operate using CANbus (Control Area Network) same protocol as the VP44. So it looks like you'll either have to build a smartbox that will send all the info to the turbo, or some how remove the computer control and manipulate the servos yourself (best idea).



Hopefully with advent of tougher emmissions Cummins will be forced to use this turbo design and the price will come down. Other wise they maybe pretty close to the cost of twins
