compression?

RE: compression?
actually compression ratio and cylinder compression dont really have anything to do with each other. just like tinman was saying, you can have a really high compression ratio and no cylinder compression. it just shows how well the cylinder can hold the pressure (rings and so on). with a high horsepower engine built to a race type of spec, they use low friction rings. they can get away with using this because they end up tearing down the engines so often anyway. one of my teachers (hot rod teacher actually) is part of the chicago-wise-guys and has lots of toys. he was telling us that one of his cars was lucky to hold about 80 psi in it. not sure what the compression was on it though, but i can tell you that it was a 6 sec car.
