 Subject: Re: AA Transaxle? German Transaxle? also Limited
 slip options?
 
 So everyone loves the Peloquin Limited slip...That seems to
 be the best
 option, if price  wasn't an issue, I'd do
 that...   Has anyone any feedback
 on the "normal" style clutches limited slip option that is
 used in other
 German transaxles and may be available, much more
 cheaply,  for a
 vanagon?   I've driven racecars and street
 machines with this old style
 limited slip, and they worked just fine....I think when I
 replaced the
 Porsche computer controlled LSD with regular clutch type
 from a turbo 911,
 the cost was nominal....
    anyone tried this style Limited slip on
 the Vanagon..?
   BTW, thanks for the feedback on our List Favorite
 transmission
 rebuilder(s)...

It isn't so much "new" vs "old", but rather type of locking differential.  The Peloquin (which is sold by numerous vendors, most making no reference to "Peloquin") is of course a torque-biasing differential.  http://images.thesamba.com/vw/gallery/pix/238566.jpg

If you can find a factory 091 LSD for "cheap", it's most likely because it's worn out, with no new friction discs available (that I'm aware of).  These 091 units are not known for strength, due to undersizing of some of the internal components.  They could have been made a lot stronger.  

I came very close to commissioning the manufacture of a true 091 LSD, with the intended market being the dragrace guys who use Type II transaxles .. but I didn't feel the demand was there.  A high quality LSD from scratch would be priced at almost double that of the Peloquin.  (BTW, even the turbo 911 LSDs require a friction disc replacement for any level of true performance.  Those all came VERY much detuned from the factory, having carbon or brass discs that go slick within a few track hours.)
