[C320-list] Engine noise

[Kurt R. Budelmann, M.D.]

Stan,

Thanks for the info re: soundproofing.  On the Defender website the kit does not contain lead foil, but the one inch thick insulation by itself does.  Therefore, can you please tell me how much insulation is needed and what other supplies are necessary to hang it?

  Jon,
     Do it !! you'll be glad you did. I used the stuff from Defender (as
  always cheaper than WM) 5 years ago that contains lead (I don't think WM
  even had it) so my weight difference was significant but so was the
  difference in sound. I had forgotten how loud the standard 320 was until
  went on a friends 98 a couple years ago - wow ! what a racket!! I put
  off adding the external handles until last spring and it was a big help
  for gripping the rear. I just used simple white cabinet door handles
  from a home goods type store for cheap.

  Dick,
  How much heavier does this make the two covers? I have been
  procrastinating on this project for a couple of off seasons now. Perhaps
  it's good time to also add the external handle that some have added to
  the aft cover....

  Regards,

  Jon Vez
