- I’ve had this manifold for about 7 years, bought brand new, powdercoated Illusion Purple and sat installed on my project since until I recently decided to finish it. Once I got it started and idling for the first time a month ago I did a boast leak test. I started at 15psi then went to 20psi with no issues then went to 25psi again manifold holding strong. Af I went from 25psi to 30psi and heard some air starting to escape from the #4 runner at the flange. Somewhere between 25 & 30 it devoloped a tiny crack along the bottom of the runner along the weld creating (2) pinhole leaks (one on each side of runner). I am shooting for 35-40psi on my setup so I am needing to upgrade to the cast version.
I would say this is a good opportunity for someone thats around 20psi to do some minor fix and have a great manifold or for someone to have the weld ground down and fixed correctly to get above that 30psi mark.
(I have videos of boost leak test showing pressure drop on cold engine and couldn’t tell much of a difference with engine being cold with first 15psi test before vs 25psi test after manifold leak.)
