QUOTE(Frank S @ Oct 30 2015, 11:28 AM)  I've ordered all the parts I need for the rebuild and the last open question I have is: What is the optimum CR for 9590 if I build up the 2056 from 2.0 D-Jet for a 914. Once Jake reported very good results with a 9560 cam and a CR of 8.8 : 1 and I'm not sure if I should go for CR of 9 : 1 with my build. Any recommendations? Thanks, Frank In for an answer also.....I will be doing a build in a few months and 9:1 comp is what I'd like to run |

I too...am interested in that info as well. |

For sea level operation the 9550 and 9590 should be kept to 8.5:1 max static CR. I have ran them at higher elevations with as much as 9:1, but never more than that.
