How much does 1cc dome size change compression?

[turbowrenchhead]

I'm making 160psi and I'm shooting for 150~155psi. I have 20's right now. What dome size should I order?

Go for the next size up

Yep. Next size up. I usually see 10psi change per cc

Three threads same question. Same answer. Have you done a squish test yet? What was the reading and how did you get it. That is really more important then what cranking compression is....

My squish is more then .050. I only have some .050 gauge solder right now. I'll get some bigger gauge soon and check it again. Sorry for the 3 similar questions. I like to get input from as many people I can. I have a ride coming up soon and I want to have my bike ready, so apologies.
