Whats the compression ratio of my engine?

[After_Shock]

Daft question (not another one I hear you say!) but does anyone know the compression ratio of my engine, 6.0 LS2 with the Harrop 112 S/C fitted?

Thanks

11:1. Blower makes zero difference. Its the ratio of total volume vs swept volume in the cylinder.
