VHP Series Five—What is it?
• Enhanced version of 12-cylinder 7042/7044GSI engine
• 7044GSI S5 = 1900 hp @ 1200 rpm; 7042GSI S5 = 1500 hp @ 1200 rpm
• Smarter, not harder
• Reduced temps for more power
– Enhanced rich-burn combustion for reduced exhaust temps similar to 9394GSI
– Cylinder head updated to reduce temps in valve guide/stem region
– Optimized piston/ring design reduces piston temps
• More fuel flexibility & increased efficiency
• 4k hour spark plug & oil change interval for reduced OpEx
Series Five works smarter, not harder, than current production Series Four

The 7042GSI S5—Ultimate Flexibility
1500 hp @ 1200 RPM
Same components/dimensions as 1900 hp 7044GSI S5
• Power limited by ESM2 calibration
Comp. • Pricing adjusted on $/hp basis
L7042GSI S5 Product
1500 HP 1380 L7042GSI S5 creates power w/ displacement at lower
115 Displacement (L) 69 BMEP—engine doesn’t work as hard
Engine Speed • More power (1500 hp vs 1380 hp) than competitor
1200 1400
(rpm) • Lower BMEP (141 vs 180 psi) increases operating
BMEP (psi) window and reliability:
141 Brake Mean 180 – No fuel derate – full 1500 hp to 2300 BTU/ft3 LHV (35
Effective Pressure
