Anyone used one of these SFI underdrive pulley fluid balancers? Opinion? I measured it at 22in. around \3.14=7.00. Am I going to need an overdrive alternator pulley? Here's the specs/part numbers I have for it. Thanks.

Part No: PDK-9004
Application: GM 346
Description: Camaro/Firebird. LS1, Fluid damper & Pump Pulley, 98 and UP

Also says this is SFI 29.1 approved.

I would run the ASP or SLP pulley. It has been proven time and time again both on the dyno and at the track.
