My SC pulley is square. Nothing like the wobble video.Check to see if your blower pulley is square...rotate it a little and take some more measurements...look at the part 4 video I posted a few min ago.
My problem is I cant get the IM and SC far enough forward.
It is very likely variance in Ford production has some IM holes slightly off. The IM that the SC bolts too could have some variance in both sets of holes. :shrug:
Whether the issue is variance in Ford production or a dropped SC cause the installer was drunk, I have 110% confidence that Whipple will help us out. Whipple excels at support. Dustin is fairly patient with all us noobs. ;)
I will test some washer shims tomorrow only to see if I have the cold idle chirp fixed. I dont want to run any significant power with a shimmed SC pulley; talking 100hp ballpark transmitted thru this setup.
Option 1:
The jack shaft is threaded so it should be possible to simply loosen the pulley mount and bring it forward 1.22mm and loctite it again. Might need a special tool to hold the pulley mount ( or geto rig a pipe wrench and risk marking it up).
Buying or making a proper tool seems like the way to go and how the design was intended to be adjusted.
Option 2:
Drill the IM or SC or both to try and get enough play to fix the problem. The SC would not be too hard to get at to pull and drill. But then It would likely need washers for the socket head bolts. If I need 1.22mm more, then that means increasing hole diameter by 2.44mm ish. This solution has more risk for angular misalignment.
