There is a huge debate regarding whether or not upgrading the IC pump will make any difference, but as far as I know no one shared their experience and what the effect on IAT2 was.
I always liked the argument that Ford's engineers felt the necessity to upgrade the pump for 13, and where I live I need everything I can get to reduce heat soak.
For reference: Triple pass H/E Data are in
For the install, I already had VMP's extension harness so I bought the harness for the pump from Tasca and connected it to VMP's. But, had I known earlier I would've bought it from VMP. They sell a complete kit for the swap.
Onto the real stuff.
The pump did actually make a difference. However, not that big of a difference. I've seen an improvement of 5* on average. On speeds above 60 IAT2 were 8-10* lower so you can say the higher the speed the better. Nothing changed on WOT but since I made that thread I changed to a 2.5 pulley and I'm seeing 12 PSI so there might be an improvement there.
So to me its worth while because of the kind of heat we get here, and I think there is some potential still left in it like going with bigger hoses to improve flow.
