Supercharger & Pistons

Would it be okay to use a supercharger producing around 9lbs of boost with flat top pistons or would that threaten the bottom end with that kind of compression? How much would flat top pistons alter the compression ratio?

That all depends on what the comp ratio is..

What is the chamber volume?

Head gasket thickness..

Is the piston @ zero deck or below?

With iron heads.. 9 to 1 is about as high as I would go.

With alloy heads.. possibly 10 to 1.
