Thanks of the info, 20 F drop should help to cool it down, I'm thinking to install hood vents too, I'll be removing all of them except one on top and bottomditto, from my automatic transmission spreadsheet findings, when I had only 2 AGS fins setup like this:
The average temp was 139.03.
Now with them set up currently like this:
the average temp so far (since 09/12) was 153.225.
This is on a 2.0L with the Power-tech. I think a 0 AGS mod would work wonders on all Darts to be perfectly honest. If there was a way to get this to work, it would cool down the bay. The best part about this is when I was running with only the 2 AGS fins I was able to get just as good if not better MPG's as I did with all of the fins installed. So, I think we are all onto something that will benefit the whole community.
