Radiator and FMIC question

Here is a pic
I had the 2800 prior to this one and basically have come to a similar conclusion about the 3800. Again I am tempted to just put a clutch fan & shroud back in to see if all the temps stay in check. I do not have any problems with customers' cars that run FMIC's and the stock fan.
Of course keeping the A/C in the Vert is aggravating the issue, but it sure is nice on those hot days to have the top down and ice cold A/C blowing
Like to hear what you think of the Villager fan, if you try it.

I am willing to bet most customers with FMIC remove the AC, I am in the same boat as you- I like AC! Nothing worse then sitting in traffic with the top down when its really hot out or if it starts to rain- which has happened once or twice on the way to or from a large car meet
A few others have told me to heat wrap practically the entire exhaust, makes a huge difference in the car

Yikes! That is a bit high, doesn't leave much margin if something were to actually fail....
I've got a villager fan that I need to install, I've got confidence that it will cool as least as well as stock w/ A/C before the intercooler is installed. I've found a writeup that uses the stock thermoswitch and "a/c idle up" feature so I'll see how that works.
On a related note, I had that little aux a/c fan but it died, I wonder if I could just wire up the new fan to the wiring for that one? seems like it would be pretty simple...
Finally, any particular reason you ran the fuel lines and fpr an extra 3' to the hottest part of the engine bay?

We have actually done testing with thermal probes while driving and laser thermometers on the dyno, the FPR location is far from being in any danger. It is also NOT 3 feet from the engine. It is 12" from the fuel rail allowing the internal dampener to still be effective.

We already have the TII aux fan installed in front of the A/C condenser. We already have our fans being turned on by the Power FC and it kicks the idle up.
It is by far NOT the hottest part of the engine bay. If you are concerned about the heat wrapped DP generating enough heat to melt the SS fuel lines, that is foolish. The car would stop running as the heater hose and engine harness would have been destroyed long before.

Testing is always superior to conjecture, so thanks for sharing your experiences/results. To be clear, I did not say it was 3 feet from the engine (the bay isn't even 6ft wide and the motor is in the middle ) I was referring to the additional hose required to mount the FPR in that location which I estimated to be around 3ft (12" from the fuel rail X 3 fuel lines = I wasn't too far off )

I prefer to see temps closer to 86-87C (186-189F) while cruising without A/C and 90-93C (194-199F) with the A/C on. Running the A/C is always going to yield higher water temps.
The TII aux fan is wired in to the same E-fan circuit, so there is no difference.
Of course it is hotter than the other side of the engine bay, but there is no available space over there. It is still not the hottest place in the bay as you stated. On the JDM models the brake booster, clutch master, steering column all much closer to the turbo and DP.
Fuel temp- it is the return line, all the fuel is already past the motor where the fuel temps could even play a role. It is about to be dumped back into the tank with all the other fuel. The minimal increase (if any) in over all fuel temp does not effect anything on our car.
