S300/S300 Triple Turbo Kit for 2001-2016 Duramax uses Three S300 Framed Turbo chargers in a compound application; two atmosphere and one high pressure. Offering great spool up characteristics and quick engagement from the atmosphere air supply. Geared more so towards built engine applications with plenty of additional fuel this combination can exceed 1100 RWHP yet still be daily driven and street friendly with mild towing capabilities. Kits are available without turbo chargers but we will need your turbos sent in for the build process.
