A:
The bypass is set at 45 psi at the factory. The bypass will start to open around 20 psi and then are fully open when they reach 45 psi, based on the factory setting. The bypass is adjustable and based on an 80 psi spring, but this will never reach full bypass if set that high (80 psi) as it would decouple first.
