Yes, those are actual gains.

1 b. No it is not fully functional. When you change the orientation and positioning of the damper it alters the frequency range in which it operates (Where's Judge when you need him)
Since the stock Harmonic balancer is retained, it would still retain the dampening characteristics (Unlike some other pulleys which replace the stock balancer with a solid pulley).

1 c. Again, have you ever thought about selling the P/S pulley seperately? It would likely be a big seller being as most folks don't want to compromise reliability by running an undampered crank pulley.
Our pulleys only came as a set. In order to reach optimum gains in HP,
both pulleys must be used.

2. We have pictures and posts online to prove otherwise (Where's Terry when you need him) Let me try and hunt them down for you! Main bearing failure is not pretty!
I am very eager to see these photos. Email them to me @

addendum - I still say at least half your claimed gain is from the P/S pulley alone. I noticed no difference between the switch from your UD crank pulley to stock while keeping both the P/S pulley and an Alt UDP on the vehicle.
Again, this is your theory. Produce a dyno sheet to back up your claims. Butt Dynos are not considered proof.
Show me some actual dyno data to back up your claims.
