I'm a n00b at this stuff to so I just have a question: When you state compression, you state it in this format, XX:XX:XX. What do each sections mean? My car (F23a4) comes stock 9.3:1 according to the 6thgen general FAQ. Why is it that the lower the compression, the better? And by lower, you mean that it goes from 9:3:1 to 8:3:1 or something? Also, you said that increasing the combustion chamber, and lowering compression makes the car faster. How does the combustion chamber increase if the cylinder can not expand? Also, what's boring and sleeving?
