I fought this for an entire summer. Similar issues. Here is how I fixed it.
Overdrive WP pulley. I had to make one as you cannot get an aftermarket pulley smaller than the crank. I did a 20% overdrive. 180 high flow t-stat. Brought idle temp down 10-15 degrees just by moving more water. Next, mounted 2 deraile high flow puller fans (need relays as amp draw is high), one comes on at 190, other at 205. Fully shrouded and covers 80% of core. shrouded fish mouth so ALL air goes through the rad. dropped temp another 10 degrees. I run 100 degrees over ambient on highway and max 210 in traffic on 105 degree days. Once second fan kicks on in traffic it cools down to 200. So, at WOT the pulley is spinning at 6500 rpm, tends to cavitate just a bit but air burps. I run WOT now and then, I run traffic every day, pick your poison. Move more air and more water and make sure rad is clean
