Did Auto Club speedway last Sunday. Ambient temps from 67*-90*.
Cooling mods:
Mishimoto Radiator
Z1 34 row oil cooler kit
Removed center wiper cowl
My Radiator and Oil cooler sprayer
Temps stayed at 220-230* all day.
Wish I had a way to test the sprayer with actual temp #'s. I was thinking of not spraying at all for one session, but I forgot. I sprayed on the front and back straights. I did try to watch my oil temp gauge after spraying and noticed it dropped 5-10*, but that could easily be from just the airflow generated on the straights.
Also the check valves (I ran 2) did not stop the drip ("crack pressure" is too low to make a difference). I would just disconnect the system when I got back to the garage.
All in all the sprayer didn't have any issues. Now I just have to decide to keep it or pull the reservoir out completely to save weight.
Next up is install of the RRP from CJ. Might start it this weekend.
Here is a small clip of some fun on the track:
