You can't convert a RATIO (which is a pure number) to a MEASUREMENT such as psi. You get such a ratio by dividing two different pressures, for example.
11.3 psi is about 584.4 Torr.
11.14 bar = 161.6 psi
A 1:1 ratio is equal to 0 PSI. 14.7 PSI is equal to a 2:1 ratio. Just multiply your ratio by 14.7 to get PSI, or divide PSI by 14.7 to get ratio. This is only in a perfect cylinder where valves close exactly as the piston reaches the bottom and stays closed the whole way, and if no air bleeds out from the valves, or between the piston and cylinder wall. Not to mention the difference between if it's hot or cold. Plus, according to the math problem, if you had a compression ratio of 1:1, you would be pushing 14.7 psi. So there isn't any REAL way of telling an engines compression ratio without getting the specs for everything.

Displacement doesn't translate directly to horsepower. That'll depend on the bore, stroke, and compression ratio.
23 psi = 1.6 bar
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Depends on the car. If it is naturally aspirated (no turbo or supercharger), then it's easy. Cylinder pressure = 14.5 (1 bar) * Compression Ratio. If however, it's forced induction: Cylinder pressure = ( 14.5 (1 bar) + Boost psi ) * Compression Ratio. For instance, in a naturally aspirated car with a 10.0:1 Compression Ratio : 145 psi = 14.5 * 10 Or in a turbo car with the unreasonably high 10.0 compression ratio with 10 psi boost : 245 psi= ( 14.5 + 10 ) * 10
A 1:1 ratio is equal to 0 PSI. 14.7 PSI is equal to a 2:1 ratio. Just multiply your ratio by 14.7 to get PSI, or divide PSI by 14.7 to get ratio. This is only in a perfect cylinder where valves close exactly as the piston reaches the bottom and stays closed the whole way, and if no air bleeds out from the valves, or between the piston and cylinder wall. Not to mention the difference between if it's hot or cold. Plus, according to the math problem, if you had a compression ratio of 1:1, you would be pushing 14.7 psi. So there isn't any REAL way of telling an engines compression ratio without getting the specs for everything.
stock compression on a ka24de found in your 91-98 Nissan 240's is 178 9.5/1 ratio
Normal compression on a gasoline engine is about 125 psi.
The ratio is 9.5.1 in the 350 vortec. Doing a compression test you should not have any below 100 psi and all should be similar to each other.
200 psi
87 - 04 compression standard 121 psi minimum 114 psi max 128 psi
then youre running about 8.5:1 compression
251.37
The lowest compression ratio of a compression-ignition engine that allows a specific fuel to be ignited by compression ignition.
A diesel engine requires at least a 20:1 compression ratio, or about double a gasoline engine. The PSI this translates to depends on the size of the cylinder. You will need to consult the manufacturer's service manual.
