B18c boost questions

By 92dxeg
- Sun Nov 24, 2013 5:51 pm #339285 ok i threw up a post a few weeks back about a lsv that i was going to build so i scraped that idea and picked up a b18c block and crank that has a fresh hone and a fresh cut crank. and i will boost it but do u think 10.1 would be a good cp ratio or 9.1 ?

I went from mid 9 compression down to 7.5:1 with a D series and it wasn't too bad so you should be fine.
