Guest shuyun Posted April 4, 2003 Share Posted April 4, 2003 In general, 8 or 8.5 to 1 is the right CR for about 12-13 PSI with premium 92 octane fuel and water injection. CRs in the low 7s will work with regular 87 octane fuel. TT With this line of thinking a Na longbock should work? Quote Link to comment Share on other sites More sharing options...
Mudge Posted April 4, 2003 Share Posted April 4, 2003 The issue with the NA setup is piston ringlands, not just compression. Quote Link to comment Share on other sites More sharing options...
Guest Zcarsmakemyheadhurt Posted April 5, 2003 Share Posted April 5, 2003 You can run that CR if you have the correct ignition maps. You need a fuel computer. Quote Link to comment Share on other sites More sharing options...
