Give me the mechanical compression ratio, measured duration @.50, installed centerline, and cam LSA and I can calculate it precisely for you.

yay!
i shall get back to you when I have that data
If you plan to do some comparisons on different setups you can take the schrader valve out of a compression gauge and then do running compression tests at X rpm and X manifold pressure on the engine you plan to modify. There might be some limitations to this such as if your engine cant make full 'normal' boost with only 3 running cylinders. Don't forget to disable the injector. :p
