WebOct 8, 2009 · Forced induction builds the motor for a variable input of pressure, thus making the effective compression that much greater than the static compression which is at 1 atmosphere. Increases in boost, which is literal compression (just like an air compressor) will cause higher effective compression levels in the cylinders. A head that has been “decked” by having material removed from the surface that contacts the block will have a higher static compression than an unaltered head, and pistons can be milled to lower compression, either on purpose or as a side effect of cutting pockets for larger diameter valves.
