The compression ratio was also increased to a value of 9:1.

It also had a slightly higher compression ratio of 8:1.

The compression ratio should be less than or equal to 20:1.

Later in the model year, a 235-horsepower version with 9.0:1 compression ratio became available.

A compression ratio of about 2.5:1 is common for software.

The compression ratio would be reduced on the high performance 440ci starting in 1972.

The following images give you some sense of the effect that different compression ratios can have on image quality.

This requires compression ratios on the order of 19 to 1.

The compression ratio of the L48 was lowered to 8.5:1 in 1971.

Higher compression ratios mean more power can be produced by an engine of a given size.
