Compression Ratio's again

[David Costello]

Anyone here every used Desktop Dyno 2000? I'm having troubles getting accurate compression ratio figures from it   just to test how accurate it was I put in all the figures from a motor I allready knew the compression ratio for....a stock L20B   Bore : 85mm Stroke : 86mm Head Chamber Volume : 45cc head gasket thickness : 0.13mm piston down from TDC : 0mm piston dish cc : 8cc   those are the specs I've inputed and it's telling me the comp. ratio is 10.08 : 1   have I done something wrong or is the software inaccurate?   Dave --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
