Whats up everyone. I went by Randys (my machinest) yesterday to drop off the valve springs for my heads. I wanted to do a quick little test on both the PAC springs and the factory springs. This is my findings:
PAC stage 2 .600" (New)
- seat pressure 95 @ 1.680
- open pressure 260 @ 1.080
Factory PI springs (30K miles)
- seat pressure 58 @ 1.680
- open pressure 160 @ 1.080
