anyone know which is more accurate? seems to have quite a little varience.

here's what i'm looking at B16 head, B18c block, pct pistons (os), 3 or 2 layer.
Cspeed says 12.14X with 2 layer and 11.80X with 3 layer
Bojangs says 12.28X with 2 layer and 12.07X with 3 layer

thanks for your time

i dont use CR tables but what i do know is for every 16 thous that you take off the head or gasket CR will increase by .3 hope that helps

 

there's has to be someone out there with some crazy spread sheet that i keep hearing about. please. TIA

 

You need a CR spread out of how -to calculate?

 

no i figured out how to use the cspeed calc.... i've seen other calculators somewhere.......just wondering why there is such the variance.

 

kewl kewl... good luck
