I dont like the idea of blowing through a maf in a turbo car because of oil issues. Especially if the cars valve cover vents to inlet per factory, but even without a catch, look how oily intercoolers get.
on another different but similar note, CRC maf cleaner FTW, says right on the can add 10 whp instantly.... it is no joke! If you clean a MAF with this stuff thats being drawn through and you feel a difference, (which you will) Id like to see someone clean their blow through setup with it and report back!
