acceptable leak down

[YZFR1]

I remember seeing this somewhere but can't seem to find anywhere. When pressurerising intake up to 25 psi or so, what is the acceptable time that boost will drop to 0 psi?

Thanks

Well if you pressurize the system past what you run at and you don't hear leaks, you're good. If you have a leak you will hear it or see it with the water/soap solution.
