On a 2568cc motor upto 9000rpm, they can push upto 2.1Kg/cm2 at a reasonable efficiency. Generally, you wouldn't want to wind them up much past 1.9 Kg/cm2.MACH 1 MARC said:What is the maximum boost that 2540's can kick out... Does anyone know?

1 bar =14.5psi
1 Atm = 14.7psi
Bar is used as a measure acting from within forcing outward to a lower pressure area. Like the air confined in your tyres.
Atm, means 'atmosphere' and is used to denote pressure acting on confined air, as in the pressure acting on the hull of a Sub-marine.
Similar masures used in different circumstances, if you then think about this then an NA engine is running at 1 atm, the natural barometric pressure, but we call this '0' on our dials.
(incidentally 1KG/cm sq. is 14.2psi)
