Shimming n1 pressure relief?

[BrynDETT]

Hey everyone, does anyone have any experience shimming an n1 to get a little more pressure? Google search comes up with basically 1 thread about it..  the pump has billet gears and backing plate so kind of invested in this pump for now.

 

Cheers 👍

What do you want to know? It's like shimming any pressure relief valve. Put shim under spring. You now have higher relief pressure.

Just after experience on how thicker shim/s to use ? Can't really be bothered with the trial and error way of pulling engine/ lowering subframe
