How much hp?

[92 Ty 1173]

Is there a formula or a general number on how much HP is gained pure a LB of boost. Someone told me it is 1 lb = 10hp.?? Anyone know if this is true or does it depend on the application?

I've heard that 1psi=7hp is a closer approximation for the 2g63 (2.0L I4 Eclipse/Talon) so I would imagine that with more displacement 10hp per psi is probably a great estimation.
