I am in the process of removing my crank fan and mounting a small 8" pull fan on the back side of the IC. It weighs a little but says it flows something like 800cfm. As with every other TTA my scoupe is trashed as well.
I think I'm also gonna move my ATS from the maf pipe to the uppipe and see what readings spit out on the scanmaster before and after the fan install. Should be a good experiment. With the closed nose of the TTA hindering airflow, hopefully it'll pull some air through the IC.......................................................................
