ATI Superdampner Question
Get a hold of the instructions and make sure you have means of meeting the interference fit requirement. I have one on the Vette and they require a 0.0007 - 0.0009" interference fit. This requires you have the tools to measure to 1/10,000". This is for the steel hub Vetter ATI pulley, not sure which one you are considering but make sure you look into this prior to purchase.
On a side not, I also pinned it. The ATI hub already will have a keyway cut into it and their pin kit is great. Lastly, once pinned, the ARP bolt is nice because it is not a TTY bolt but is rather tightened to 190 lb-ft using ARP Moly Lube on the threads and washer. Later removal is a snap. Make sure you build a tool for install as well, don't pull it on with the threads.
