from the very limited sources i have (omniman, c-speeds compression calc, and various HT users) there seems to be a rather large difference of opinion on the effective compression ratio's of CTR pistons in blocks other than the b16b
personally the range of difference is the problem. to me .2 or .3 difference wouldnt bother me, but recently people have been talking of 1+ point differences in the compresion calcs available online today!
i really trust omnimans opinion, i have spoken to him once about a particular head he ported, and the #'s he achieves speak for themselves.
i woul like some help in getting to the bottom of this. i have a set of of overbore ctr pistons available to measure if anyone can point t me what needs to be measured.
