has anyone tried to measure crankcase pressure at WOT with the higher boost pressures that most of us are running. I'm thinking no matter how good the rings are sealing there is at least 3% blow by on a good day. Now double the factory boost from 7 psi to maybe 15 psi, is the factory CDR just too small? in the factory service manual there is a note state the CDR was designed to handle 4 cfm of blow by. a 6.5 at 15 psi boost and 3% blow by at 3600 rpms is just over 15 cfm, thats almost 4 times! maybe a combination of the CDR and the addition of a downdraft tube in the down pipe is needed.
