    Can I make this 65 911 QUIETER??!!

    I’m a long time Porsche nut that has owned a bit of everything up/down the various generations including a few early 911s. I just got back my 1965 full mechanical rebuild. It was an amazing job. I have one of those questions/comments that I usually laugh and poke fun of owners for asking. Additionally, I don’t think I’ve EVER asked to make a car quieter; only louder!

    I’ve attached a couple of clips. Every AC’d 911 I’ve owned has had a high pitch whine that cuts through the exhaust note at times. I have owned two 2.0’s before. I don’t remember anything having such a pronounced high pitch whine/shriek that shouted over the top of all other noises.

    I’ve never known what creates the signature ac 911 high pitch howl: fans, intake, other? Is there anything that can be done to tone it down in my otherwise perfect 1965 w/out knocking out all the other quieter, good noises (sound deadening)? Or do I need to come to grips with tinnitus or selling my dream fully sorted 1965??
