To poptarts: wort boiling temp depends of its OG and normally it's higher than water boling temp. If you boil a triple's wort you can easily reach 110 C. Sugars inside the wort have the effect of raising boiling temp.

As suspected your counterflow length seems quite short... You could try to chill down your tap water letting it pass into a copper immersion chiller drowned into a bucket with iced water. It should improve heat exchange efficiency.

How long is your counterflow? Maybe it's just a problem of short length of the counterflow pipes which results in reduced heat exchange surface. I have a 10 m (32.8 feet) long counterflow with wort pipe having 12 mm (0.47 inches) of inner diameter and I can cool wort from 105/110 C (221/240 F)...
