This is addressed mainly to those who have themselves had their engines changed from the 80hp to the 100hp version and have therefore been able to compare differences in any tendency towards carb ice.
I have been a professional pilot for over 40 years, learned to fly on the AT6 Texan (Harvard), built my own Europa and have flown it for over 16 years with a 912UL 80hp without any form of carb ice protection, apart from a shutter to keep direct cold air out of the plenum (Classic cowl) and let warm engine bay air in. I rely on the carbs being at the back and fairly close to the exhaust tubes of the rear cylinders.
More than 95% of my Europa flying has been in Scotland and I have often been in conditions where carb ice is likely, even in temperatures above 20C with high humidity. Never has there been any hint of ice in the engine.
But although the 100hp engine will run hotter than the 80hp unit, I don't assume that therefore there will be less tendency for carb ice. Maybe something different will happen in the carbs to increase the chances of ice; I just don't know!
Fitting the water heated anti-carb ice devices would necessitate considerable modification to my air shutter, so I would like to avoid doing that if possible.
Please give me your thoughts if you have personal experience of getting the higher power engine installed, or if you know of anyone else who has been in a similar situation to me. Thanks.

Jonathan,
Just fit the standard heaters and enjoy your flying without worrying about icing. One of many joys in flying the Europa is that you dont have to worry about icing (or mixture or cowl flaps or how much fuel you are using, etc) so l would think it is a no brainer.
Perhaps consider a full firewall fwd installation?
Regards
John
