N/A compression figures

[Kempy]

I need to test a friends car and not sure what sort of pressure it should be reading, Is there a difference between turbocharged engines and N/A? Im assuming there would be, but how much? Thanks in advance ;)

that's going to depend upon compression ratio, and inlet valve closing. In general you'd expect to see higher compression on a NA engine.

I see, cheers mate. :)
