Two factors make high compression possible with little loss of quality.

This model featured a vertical engine with alloy head and higher compression.

Larger propellers give a longer combustion time and so higher compression.

Achieving much higher compression is simply not possible without discarding some perceptible information.

But it can't stand high compression - a major drawback to power output.

It was powered by a high compression 120 horsepower V-8 engine and known as the police chief's official car.

He had the idea to develop an engine which relied on a high compression of the fuel to ignite it.

Some of the early 1968 models also came with a slightly higher compression "H" code cylinder head.

It must use higher compression to produce an equivalent cooling effect.

According to its author, this program can often get higher compression than other optimizers by 5-10%.
