Good morning folks.
Richard one big reason Porsche went to water cooling is the noise factor. The water cooling helps quiet an engine. Germany & most of Europe was moving to tighter noise standards. Porsche would have had to add a lot of sound deaden mats to meet the sound restrictions. Adding dead weight to the rear of a 911 is never an ideal solution.
Water cooling makes for a inherently quieter engine. One reason I love the whirr of a air cooled 911 engine. I don't like real loud mufflers because I can't hear the spinning cam chains and those overhead cams. Actually I guess they are beside the heads, not over them but twin both-side cams sounds strange.
Water-cooling allowed higher technology and ultimately more power as well.
