So....
Once I remove this shroud my car runs great at 180* down the road, no knocking/pinging/dieseling at shut-down. Car heats up to 110C if left sitting still long enough.
I am headed to do the coolant eval.

Since your main problem is stop/go traffic, add another fan just like the one you have in the rear, but to the front of the radiator, pushing........I did this on my street car for parades, I added a 12" fan (cause I had one)(I'd go bigger,at least 16") and reversed the wiring so it pushed thru the radiator, helped tremedously while doing 45 minute to one hour parades on the Forth of July when the outside temp was 100 degrees!!!!!!!!!!!!!
Put the puller fan to one side and the pusher fan to the opposite side of the radiator and I think you'll be fine is city driving.......
Your radiator is not as large as I would like to see, but that's all you can use on your car, so you need to increase low speed airflow, the only way is to add more fan/fans........
Looking back, your radiator is the same as both my cars,cept mine are 28" wide instead of 27" like yours, not enough to worry about..... I would suggest putting the 16" fan you have in the front, pushing and get a 17" fan like in the picture I posted and put it in the rear pulling, that with a change of pulleys and you should be good to go.........
BTW: put the front fan on a manual switch and use as needed.....Not sure how your prsent fan is wired,but I keep mine on manual switchs, I don't trust those automatic switches to come on.......
