It depends greatly on the salinity of the water.
Pure water, is 212F/100C....
Add a tablespoon of salt per gallon, and dissolve. the boiling point will increase a few degrees.
Add salt to saturation, and boiling temperature will rise significantly.
Supersaturate water with salt, and the boiling point will rise even more.
I am sure there's a chart somewhere in some chemistry book listing salinity vs boiling/freezing points... but I am going to GUESS that salty pasta water will probably have a boiling point around 230-250F.
