How about the STAR tollway in Batangas.... my dad told me the top speed there was 140 kph
The STAR tollway highway isn't that safe to go really really fast because of the way to road rolls and changes direction. Just doing 150 to 160kph is pretty much the limit of the typical road cars we drive.
As for me, I have done a peak of 165kph on Star tollway in my Corolla. I haven't tried my Sentra on it though.
