At what pressure does the oil bypass valve open?

Does anyone know at what pressure the oil pump bypass valve opens?

I'm gathering information to decide if I'm doing to run a slightly thicker oil on track.

Wix lists 8-11 for its replacement: http://www.wixfilters.com/Lookup/Par...x?Part=51334XP

edit:// oh read that wrong, you want oil pump bypass. Its ~90-100psi (via Stack oil pressure gauge)
