What engine does the MD1600-01 use?

The Mitsubishi S16R-Y2PTAW-1 — a 65.4-liter (3,989 cu in), 16-cylinder V-configuration turbocharged and water/air-intercooled diesel producing 2,346 HP at 1800 RPM for standby use. The S16R uses the same bore and stroke as the S12R (6.69×7.09 in), adding four cylinders for the step from 49.0 to 65.4 liters. Compression ratio is 14.5:1. EPA Tier 2 certified for stationary emergency standby.

What alternator does the MD1600-01 use?

The alternator selection is voltage-dependent. At 480V (4-lead wye) and 600V (4-lead wye), Blue Star specifies the Stamford S7L1D-D. At 208V and 240V, the specification is 'Consult Factory' — these high-current configurations require factory engineering at this power level. For the 4160V configuration, a Stamford MVWI734H medium-voltage alternator is installed. All are 4-pole, brushless single-bearing units.

What controller does the MD1600-01 use?

The DSE DCP7310 Digital Control Panel — CAN Bus J1939, digital metering, RS-485, 8 programmable contact inputs, 10 contact outputs, cULus Listed, CE Approved, NFPA 110 Level 1 compatible.

How does the MD1600-01 compare to the MD1250-01 and MD2000-01?

The MD1250-01 uses a Mitsubishi V12 engine (S12R, 49.0L, 1,881 HP) on a smaller 220×95 in base. The MD1600-01 moves to the V16 platform (S16R-Y2PTAW-1, 65.4L, 2,346 HP) on a 244×89 in base — 24 inches longer but 6 inches narrower. The MD2000-01 uses the S16R-Y2PTAW2-1, the higher-output variant of the same V16 block (65.4L, 2,923 HP), on the same 244×89 in footprint but 14 inches taller (135 in vs 121 in). Fuel at full load: 99.1 gph (MD1250), 127 gph (MD1600), 155 gph (MD2000).

What ventilation airflow does the MD1600-01 require?

The MD1600-01 requires 75,053 CFM of radiator cooling airflow and 5,932 CFM of combustion air. Heat radiated to the equipment room is 1,896,540 BTU/hr, with 2,170,020 BTU/hr rejected through the jacket water cooling circuit. At this power level, equipment room thermal design is a first-order structural and mechanical engineering concern — consult an MEP engineer before specifying an indoor installation.

Overview#

The Blue Star MD1600-01 is a 1,600-kilowatt Tier 2 diesel standby generator — the first model in Blue Star's lineup to use a Mitsubishi V16 engine. It is powered by the Mitsubishi S16R-Y2PTAW-1, a 65.4-liter, 16-cylinder turbocharged and water/air-intercooled diesel producing 2,346 HP at 1800 RPM. At this power level the generator moves decisively into utility, military, and large industrial standby territory.

Blue Star Power Systems (North Mankato, Minnesota; DEUTZ AG subsidiary since 2024) assembles the MD1600-01 on a structural steel base with a Stamford S7L1D-D alternator (480/600V configurations; consult factory for 208/240V) and DSE DCP7310 controller. The unit is three-phase only, available from 208V through 4160V.

The Mitsubishi S16R platform#

The S16R extends the S12R's bore and stroke (6.69×7.09 in) to 16 cylinders, yielding 65.4 liters of displacement and 2,346 HP standby. The transition from V12 to V16 is reflected in the unit's physical profile: the MD1600-01 is 244 inches long on the same 89-inch-wide structural steel base used by the MD2000-01. The intercooler remains a separate water circuit from the jacket water system, requiring two independent fluid maintenance regimes.

When to spec the MD1600-01#

1,250–1,600 kW continuous emergency loads on three-phase power
Large industrial complexes, utility substations, military installations, and major data center blocks
Sites requiring 4160V output at 1.6 MW without a step-up transformer
Buyers who need the V16 platform's output headroom but whose load analysis does not justify the MD2000-01

Our service experience#

At 34,450 lbs OPU, the MD1600-01 requires structural pad engineering comparable to a small vehicle fleet deployment. Fuel at full load (127 gph) means a 2,000-gallon tank provides approximately 15.7 hours of runtime — plan accordingly for extended outage scenarios. The 75,053 CFM radiator airflow requirement essentially defines the generator room design. This unit is best approached as an infrastructure project, not a product procurement.
