*The "governed speed" is the highest speed which produces useable power. Above the governed speed, engine power drops VERY quickly. Other interesting engine speeds:

1994  160, 175 HP 15-18 psi  Holset WH1C 12 sq cm turbine housing
1995  160, 175, 180 HP 15-18 psi  Holset HX35W 12 sq cm turbine housing

The stock 12 cm housing on 94+ engines is OK up to about 240 HP, beyond which the small housing restricts the exhaust and raises EGT. A 16 cm housing provides enough low speed boost for an enhanced engine, and the exhaust runs cooler at high speed.

(*) Fuel Filter:

The FS19519 is a upgrade for the FS1253. The FS19519 has the same micron rating a the FS1253,
but has a larger dirt holding area and a higher flow rate. These two filters can be interchanged,
but the 19519 is larger and more difficult to install. You may need to loosen the filter housing mounting bolts
to install the filter.

* Oil Filter:

LF3959 superseded LF3935, LF3885, LF3949 for all model years.
Cummins 3942470 supersedes 3931470.
Mopar 5016547AC - replaced 5016547AB
Fleetguard LF3984 has been upgraded without a number change.

* Cummins Thermostat:

A series of revised part numbers has been issued - check with a Cummins parts department for the latest.
P/N 3934373 eliminates temperature fluctuation but engine warmup is slower and the operating temperature
is lower than with previous t-stats.

* Lift Pump 3925709 has been replaced by a new design PN 3936316
