From what I've read the lower the better for boost applications. So, If boost pressure is say 10 psi. Then you have 11:1 compression ratio. peak pressure when the piston is at top-dead-center would be 11*10=>110 psi. If compression ration is at say 10:1 you get 100 psi peak pressure. Please check my math though. But amount of boost will depend on the engine if the parts can handle the pressure.

Edit: The math is wrong, here but the idea is the same here's a better explanation => http://www.turbo-mini.com/70947.html
