That depends on the hardness (durometer) of the rubber. It can be quite low and range from 100 psi to over 1000 psi. If it is very thin, then since it is nearly incompressible (poisson ratio approaches 0.5) then the modulus increases to a much higher value, depending on thickness , and can vary from 1000 psi to 10000 psi in general, and approach over 300,000 psi in the limit. You need to know the dimensions and durometer.
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
150-160 PSI
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.
150 to 160 psi
Compression readings for the EA 81 are 1130 Kpa or around 160 Psi
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.
135 to 160 most important thing is that they are all less than 5 psi difference
