Happily, the cooling modifications have been mostly successful. After testing at Seattle's Pacific Raceways showed consistent mid 230F water temperatures, I pushed the car a bit by moving from the 3.1" supercharger pulley to a 2.94" pulley (gaing over 30HP) and took the car to Portland International Raceway where it was around 90F. And, the Cobra didn't like it so much! Water temperature easily rose to above 240F which is dangerously close to the 245F "limp mode" cutoff which really is a big damper on fun! Fortunately, by driving with the heat on full blast, the water temps dropped below 240F. It was a fun and HOT day! Below is some in car footage from the event. I'm chasing an Ultima supercar; which is always very satisfying to hang with such cars in a lowly Mustang :)
We've since then dropped back to the 3.1" pulley and added some heat shroudinng around the radiator to help air move more efficiently through it.
Now that the heat issues are resolved we are also replacing the stock shocks, Steeda street/sport springs and Steeda camber plates with a Maximum Motorsports coilover suspension.
On Aug 20th I'll have a chance to try out the new suspension at Pacific Raceways and shake out the car before our early September trip to Sears Point in Sonoma (my first time there!).
