"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
3-2=1 1+600=601 601 is the answer
an example of a ratio is the difference between two numbers or sets of numbers such as 600 and 200... the ratio is 400...
6/14 = (600/14)% = 42.857%
240 of them.
600It is: 600
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.
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
It should not be under 100 psi and not over about 135psi for a stock 2-stroke.
then youre running about 8.5:1 compression
600 psi
