I cut some holes in the bumper last night after getting home and my trip to work this morning was 190-195 so it did give me a nice drop in temps. I will be takking the bumper off for the drive home tonight to make sure it is air flow.
From a standstill it takes along time to have the temp climg with the a/c on at least 30min to hit 190 with the isis shroud and fans, the altima fans MAYBE 1-2 min longer to reach that temp, flexlite was same or sooner then isis
I am considering adding a third fan, a puller on the condensor to see if that will help but it would require me adding a quest alternator if i want to run the a/c
