I have searched the archives and found a lot on the Underdrive Pulley Kit, from SHO Shop specifically. I can't seem to find where people got them installed, unless they did it themselves. Any suggestions on where and how much? I don't have the time or the tools or the experience to do it myself. I have had the kit for at least 6 months now and am dying to get it installed.
Thank you.

Suggest avoiding all crank UDPs for engine longevity sake. On group buy forums you can now order alt & P/S UDPs..a much better plan at a great price.

Opps, saw you already have it. I have the SHO-shop P/S pulley alone and it works great, you could add the alt pulley if you want. Search DMD or dual mode damper...

I have seen both sides of that argument. SHO Shop claims that their kit does not affect the longevity of the engine. I guess I would be willing to take the chance. The SHO Shop tech also claims he has not had any neg feedback from the kit yet. What kind of results did you see from the P/S and DMD? Did you just replace the factory dampener on the crankshaft pulley?

1. Well duh. They are in the job to SELL them! How can removing a part that stops destructive cranks harmonics NOT incur longevity and reliability problems! Exactly. The higher the rpms the worse the problems too!
2. Yes. That is your call. We were just warning you of the possible major repurcussions of your actions to gain maybe 2HP.
3.  See #1. Several folks here have had engines fail while using them. Respected engineers have documented why they are bad. Someone that actually made the OEM damper further elaborated on that information.
Of course they are going to say it has NO negative feedback. See #1 AGAIN!

Just for informational purposes only, I know of 3 counting mine svt's with UDP's. One with over 70,000 miles on it and no ill effect, another with 56,000 on it and mine with close to 40,000 on it will no ill effect. My opinion is my 99 svt motor blew just because it's a Ford WITHOUT the Udp installed so it'll blow again with the UDP installed regardless. Oh yea all 3 of us are always well above the 5,000 rpm range on a consistent basis. So yea I'll take the 4-5 plus hp proven (my friend here) dyno advantage and run with an engine that's given me fits anyways.
Thanks,
Eric

Also FYI - my car has 73,000ish miles on it (52,000 or so with the UDP) and still runs fine. Mileage (or engine life) may vary. Hits 5-6k RPM's on every shift 
also, Lance has a pulley on his 95 and showed no elevated metal contaminants (ie bearing wear) from his Blackstone oil analysis

This has been debated extensively but let me try this..
Would your 99SVT have blown if it had a DMD???
What we know..
1) There is no debate (I think) that the original damper failed to adequetely prevent crank bending harmonics. The debate is wether or not the crank bending "whip" is causing the bearing failure OR not. At least 2 bonified experts feel strongly that it is, at least one that it is not. This is unlikely to be settled as no research is being done & Ford has moved on.
2) Even if a UDP is no worse than stock...you cannot run a DMD with an UDP. So you must choose....
3) You now have a choice...can buy UD pulleys for accessories and STILL run the DMD.
As an asside..a pre/post dyno showed a 2 HP gain with DMD. Dyno error vs gain from reduced friction???
Do as you will my friends...
