Auxiliary water pump
Just get a good electric water pump and be done with it.
Decide if you are going to race much, or just once or twice a year.
How hot does it actually get
True, it would be easy enough to do but then the money that was spent on the serpentine setup would be partly a waste.
I worked on this car all winter and finished up a couple months ago but only made it to the track twice. The reason is front end vibrations that I havent figured out. I have bought new wheels and tires and 3 of the 4 wheels were out of round so I had Summit exchange them. When I'm at 90-100mph, the front starts vibrating and I have to let off before the end of the quarter. I'm only running 12.2's now, but know the car will do much better with a proper launch, and a good top end.
So, I do plan to race about every weekend next summer. I love racing. With the 4:30 locked rear end, its not too good on the road so I wont be street driving it much, except to test and tune.
When I did a few hot laps, the car got to 220 degrees. It just takes forever to cool down so I figured that if I could circulate the water and leave the fan on, it would cool much better in the pits.
I may have just talked myself into the electric water pump, lol
