100 psi is needed to keep a forklift safe
Normal compression on a gasoline engine is about 125 psi.
200 psi
87 - 04 compression standard 121 psi minimum 114 psi max 128 psi
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.
then youre running about 8.5:1 compression

"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Engine compression psi? Radiator cap psi? Engine oil pressure psi? Tire pressure psi? Fuel pressure psi?
With a compression gauge.
