Overview#
The Blue Star VD350-01 is a 350-kilowatt EPA Tier 3 diesel standby generator built around the Volvo Penta TAD1352GE — the higher-output variant of the 12.8L inline-six used in the VD300-01. This is a current-production active model.
The TAD1352GE produces 537 HP versus 456 HP from the same 12.8L displacement, achieved through increased boost and fueling. The trade-off is a lower altitude deration ceiling: 3,280 ft versus 6,560 ft for the VD300-01.
The Volvo Penta TAD1352GE platform#
The TAD1352GE is the mid-range variant of Volvo Penta's 12.8L industrial diesel family:
- Same 12.8L displacement as the TAD1351GE (VD300-01) — identical bore (5.16 in), stroke (6.22 in), and compression ratio (18.1:1)
- Higher output tuning — 537 HP (401 kWm gross) vs 456 HP (335 kWm) for the TAD1351GE, with 19 kW fan power consumption at 1800 RPM
- V-ACT combustion technology with electronic high-pressure unit injectors, overhead camshaft, and four valves per cylinder
- 3,280 ft altitude ceiling — rated power available to 1,000 m, still adequate for most Bay Area and Valley installations but not mountain sites
Variant selection guide#
The VD350-01 sits in the middle of Blue Star's 12.8L Volvo Penta range:
- VD300-01 (300 kW, Volvo TAD1351GE 12.8L) — same block, 50 kW less, but holds its rating to 6,560 ft. Choose this for high-altitude sites or when 300 kW meets the load study.
- VD400-01 (400 kW, Volvo Penta) — next step up on the 12.8L platform if 350 kW is marginal for the load study.
- JD350-01 (350 kW, John Deere) — same kW class, different engine OEM. John Deere's dealer network may offer faster parts access in agricultural regions.
When to spec the VD350-01#
- 280-350 kW continuous emergency standby loads on diesel fuel at sites below 3,280 ft elevation
- Large commercial and light-industrial facilities: hospitals (non-critical), hotels, large retail centers, school campuses, manufacturing plants
- Applications requiring Tier 3 compliance (most US jurisdictions for stationary emergency standby)
- Competitive bids against Kohler, Cummins, and Generac units in the 300-400 kW class
