sorry for the newbe questions

 

a good tuner should be able to calculate that for you, and also CR is not needed to be able to tune a vehicle....

 

Google the formula. Sorry I can't remember I think u have all the details just need to add bore and gasket thickness. And ur runner might ask. If u still cant calculate Ill try for u

 

Sorry I just saw the .026

 

www.csgnetwork.com/compcalc.html try this not a formula but u plugthe numbers. Still like the formula better
