There you have it -- the Code3 pulley is lowest total cost and the lowest cost per % gain (barely) but is also the lowest in performance gain.
The 185MM pulley is $300 more but provides an extra 6% gain in boost.
Went head to head with all but the 181 size at the last LET track event. All on SRT6's with similar other mods. All of these cars were with in one tenth of each other all day long. So they are all good pullies, Code3 is just cheaper and way easier to install (most of the time lol )
