Interesting, that is a pretty small compressor and an awfully large turbine. That should yeild a relatively low drive pressure. That should have nice quick spool up too. However, I don't know how much HP it will support in a dodge, the dodge will also have higher boost pressures as well, because it has less cylinder capacity to swallow the air. All boost is is backed up air in the manifold.diesel_ram_man said:I don't know the exacts but the they range from a 55-59mm compresser, and 76-82mm turbine.
The Garret bb for a 7.3 is a GTP38R.BlackSuperStroker33 said:I belive those are the same turbo's used for the 7.3L upgrade. The kit for the 7.3l is about 1800 sometimes around 1500. The kit for the 7.3l uses the 88mm compressor and they are garret ball bearing units. The do spool fast and make lots of noise. I belive they have pushed a few 7.3l's into the 600hp range and hold up really great. The cool thing is they spool sp good with just a chip there just fine you don't need big injectors to worry about lag on a 7.3l. But I don't know how this would all work on a cummins.
