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

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.
