Knock and horspower loss questions??

How much power do you loss per degree of timing? ie say you have a motor pulling 1-8 degrees how much are you loosing?

1 deg is neglibible, 8 is a lot. I'd say that 8 deg would be 3-40hp or so.

This is highly dependent on the car, tune and setup, but in most cases, 1 degree is worth about 5 RWHP, like Rich said.
