If the car was available with a heating system that came without the evaporater, you are totally safe removing it. If it is part of the internal HVAC sysem, and can't be removed without leaving a gaping hole, then it is a gray area at best.

Most guys??? Well, most guys kid themselves that the weight is going to add a second a lap, or that it is a "safety" issue and chuck the core altogether! OK, maybe not "most"!...but there does seem to be a strong resentment to keeping it...

Personally, I kept it, and it is part of the cooling system. I think of it as a radiator in a spot where I don't mind the weight. I have the heat on all the time, and the fan is always running. Theoretically, I can run a smaller radiator up front. Ok, thats silly....I would never remove it or block it though...every time it rains, the number one reason guys have problems is visibilty. I've never had a issue......
