"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
To divide 600 in the ratio 3:2, you first need to find the total parts in the ratio, which is 3 + 2 = 5. Then, each part is worth 600/5 = 120. To find the two parts in the ratio, you multiply 120 by 3 and 2, resulting in 360 and 240, respectively. Therefore, 600 divided in the ratio 3:2 equals 360 and 240.
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%

To convert a compression ratio of 16:1 to psi, you need to know the atmospheric pressure, which is approximately 14.7 psi at sea level. The effective cylinder pressure can be estimated by multiplying the atmospheric pressure by the compression ratio: 14.7 psi × 16 = 235.2 psi. Therefore, a 16:1 compression ratio corresponds to an approximate cylinder pressure of 235.2 psi at peak compression.
To convert pressure in psi to a compression ratio, you typically need to know the ambient atmospheric pressure, which is approximately 14.7 psi at sea level. The compression ratio can be calculated using the formula: Compression Ratio = (Absolute Pressure inside the cylinder + Atmospheric Pressure) / Atmospheric Pressure. Therefore, 160 psi would yield a compression ratio of approximately 12.9:1 when accounting for atmospheric pressure.
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.
To determine the compression ratio from the psi (pounds per square inch) reading of an engine, you typically need additional information, such as the specifications of the engine, including the displacement and the type of gauge used for the psi measurement. However, a common method is to use the formula: Compression Ratio (CR) = (Absolute Pressure in Cylinder + Atmospheric Pressure) / Atmospheric Pressure. For example, if the atmospheric pressure is approximately 14.7 psi, the absolute pressure would be 155 psi + 14.7 psi = 169.7 psi, leading to a rough compression ratio of about 12.5:1.
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.
The Polaris XC SP 600 snowmobiles typically have a compression ratio of around 120-130 psi. However, the ideal compression can vary slightly based on the specific model year and engine condition. It's important to check the manufacturer's specifications or consult a service manual for precise guidelines. Regular maintenance and proper fuel type can help maintain optimal compression levels.
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.
