How can you measure the C/R of an engine without taking it apart... I'm trying to figure out the C/R of an engine in a car I'm looking to buy, the guy selling it says it has 11.7/1 C/R... I would like to know if there is a way of checking this out without taking the engine apart

 

compression test. that COULD be a be a determining factor.

 

whats the CR of ctr pistons in b16a engine?!? stock everything...

So is there anyway of checking what the Compression ratio is without taking the engine apart? Like a compression test? Is there a formula for figuring out the C/R of an engine?

exactly 11.43:1 CR (I just built one for a customer )

as far as finding out compression, The basic concept is calculate volume above piston at BDC (bottom dead center) divided by volume above piston at TDC (top dead center).
