Engine and Turbocharger Combinations
• Cooper
ET24
- Cooper 2 & 4-cycle engines (2,400 – 12,500 Hp)
- One turbo supplies air for ~ 2,400-6,000 hp on a 2-cycle
- All 4-cycle LSV engine that use ET24’s only require one turbo
ET18
- Cooper 2 & 4-cycle engines (1,500 – 7,000 Hp)
- One turbo supplies air for ~ 1,500-3,000 hp on a 2-cycle engine
• Currently upgradecomponents available
- One turbo supplies air for ~ 1,500-3,000 hp on a 2-cycle engine
- Most 4-cycle LSV engine that use ET18’s only require one turbo
ET13
- Cooper GMVH-6 and Superior 825’s 12 & 16 cylinder
CB13
- Cooper GMVH-6C, GMV and GMW CleanBurn Conversions

Success Story One
• Unit Description• GMWH -10
• Equipped with HPFI
• HPO-90 turbocharger
• Non pre chamber
• 3 gr/bhp-hr permit
• Problem
• Turbocharger reliability
• Operating issues during high ambient condition• No waste-gate margin
• Problem maintaining air/fuel set-point
• Forced to operate with retarded ignition resulting in increased heat rate
Resolution
• New air specification created
• Upgrade turbocharger componentsbased on air spec
• Build and test turbocharger• Build and test turbocharger
• Field installation and testing
Results
• Increased air flow rate
• Maintain waste-gate margin of 19% at alloperating conditions at 100 deg ambient
• Increased reliability
Success Story Two• Clean burn three package for the GMV and W330 engines
Emissions• .5 g/bhp-hr NOx
• .9 g/bhp-hr CO
• .5 g/bhp-hr VOC
• .3 g/bhp-hr CH2O
• Ambient horsepower up-rate available at 100 deg F
• Large operating range available• 80-100% RPM
• 70-100% Torque
• Lower Heat rate - 6,300 btu/bhp-hr
