[Shotimes] RE: Underdrive Pulleys WAS: Valve lash done...

No, it's the old Hypertech that came apart on the V6s, the ASP have been
fine, AFAIK. My former '89 has the ASP pulleys.

It was the SHO V8 ASP pulleys that had a couple of harmonic balancers fall
apart.

I thought that the ASP pulleys were the ones that came apart..I didn't
realize that Hypertech ever made a UDP set for the SHO? How old are
they?

I have a very early Hypertech underdrive pully set on my '89
(crank and alternator) and they have been perfect since
installation.  This was the brand that later got a
reputation for coming apart, but mine have been on for about
120,000 miles with no problems.  I did mark mine a few years
ago to see if it was turning any, and so far so good.  I
think there was just one bad batch or run of those pully's.
  at the time I talked to Hypertech at length about the
problem, and they said it had been taken care of  (and Ford
says the SHO V8 cam situation is just a "few" cars too, so I
took that with a grain of salt.).

I agree, the UDP made a difference I thought I could feel,
and (knock on giant redwood) I still have all my original
pullys, alternator, A/C and PS pump as of 180,000 miles.
