Thread: Technical Question: Compression Ratios

if you post a simple

engine: high port
head gasket: .04 cometic
pistons: euro
compression: 10:1

i think thats a pretty easy way of seeing the estimated compression ratio. we dont need spot on but ball park CR's are perfect.


ill start it off but i dont know the end compression ratio

engine: bone stock high port
headgasket: .04 VE
pistons 1.6VE
compression: iv been told around 11.5:1
93 octain: safe?
