2014 CTS-V Sedan A6
Holy shit that's wrecked. Glad it didn't leak and cause some kind of damage to that glorious engine. I wonder how the Kong lids are holding up to the 2650.So.... surprisingly, the lid doesn't leak.
But the brick does NOT like 19psi. That is fin deformation that matches the blower opening pretty well on the underside (facing the rotors). The top (exit) of the brick looks perfect!
Going off this, I'd say ZL1 lids are not ideal over 15-16psi.
Could also be the larger rotor packs of the 2650 creating a more abrupt transition to high flow contributing to the deformation. Hopefully the Kong lid proves itself.
Are you going with the new billet brick?
