Loss of boost on C-kit
I have just had my C-kit rebuilt and the slip set to 16 ft-lbs but i am currently only seeing 12 PSI at the manifold.
I have pressure tested my entire system and have found and fixed a few tiny tiny leaks but i dont think it would make me lose 3 psi.
Everything in the charger is set right but the only thing that may be causing it is the wheel has had a light touch down about 10mm in on the outer edge.
Im turning a prop pretty close to a 15/24 to 8450 RPM with a 82mm reduction ring.
I wouldnt of thought the very outer edge would have that much affect on peak boost?
Get the wheel replaced?

Get the wheel tightened to 40 nm and put some red loctite on the wheel,the bigger wheels tend to slip,due to the bigger power they make.
Try this ,almost sure this is the problem you have.

Yeah the wheel is tightend to 35NM with red loctite.
Will test tomo and maybe increase it by 5NM and see what happens.

Yeah i found some really tiny leaks coming out of the adjustment screws on my regulator and bov.
Guys i would def check these if you are running these as they are only sealed by an oring but they can still leak out the M6 thread.
I just put some thread tape around the thread and tested again and no leak.
I pressurised the system to 17 PSI and sorted these tiny leaks but i just dont see a 3 PSI drop.
