the crane duration rating is actually at 1mm, and not .05.
which causes for a misleading comparison because then the results are skewed since bc's are rated at .050

between those cams, they all have 3 different "ideal situations"

bc2 - good street cam for all around power

14 - spool the turbo up quicker. proven ~300rpm spool gain. wont make power that you need it to as you get near/past 6k

bc3 - top end, while still retaining some streetability.

Cool that helps out... now add the crane 16s and crower 2s into the mix

crower s2- too large of duration/lift combination to actually take advantage of for your powerband/rev limit.

id personally just rock 16s and be done w/ it.

joe smalls · 05-13-2008, 09:23 PM

added crower 2's and the rest of cranes line
