Default Highest fermentation temp increase you've seen? (above ambient)

Just curious what is the highest fermentation temp you have seen (rise in temp of the beer above ambient air temp).

My current Robust Porter using Nottingham Ale Yeast is currently 48 hours into fermentation and is 8 degrees above ambient!

Beer temp 68 F
Air temp 60 F

Wow. Now I really am thinking my first brew came out bitter because I fermented it at 68 ambient so my beer might of reached 76 F!

Next up: Amber Ale
Primary 1&2: 90 Min IPA clone
Primary 3&4: Belgian Wit
Keg #1: White Mosaic Pale Ale
Keg #2: Empty
Drinking: Amber Ale, White Mosaic Pale Ale

I have seen 8 degrees pretty regularly, even upwards of ten. 68 is a great ferm temp for ales.
