Just put the racepak on and it shows 21" of vacuum above 5000rpm I have the regulator set for 11" and anything passed 14 my oil pressure starts to go down. Have you had to modify the regulator beyond their instructions to get the vacuum down?
This is what I have.

Wish mine sealed that well Actually I use the Star regulator for the MOroso pump. Works much better as does thier baffle.

I ran the enhanced 4 vane 22842 on my 430 - with the 22633 regulator.

I had removed all the shims when starting off and added shims to get to 12-14" on my wet sump setup.

IIRC we used 2 shims to get there.

Beleive it or not sometimes it takes 2 pop off valves. My buddy had to use 2 on his engine to get the vacuum set correctly. 21 inches is a lot of vacuum. Me personally I would not run over 10 inches of vacuum.

I'am going to try the one Al is using looks like it will bleed off more air I have 1 shim in it now. I want to get it down between 11-12 If that one doesn't work then I'll have two thanks.
