Q: Can I use an Air Bypass Valve on a forced induction engine? A: Do NOT use an Air Bypass Valve on engines equipped with forced induction (turbo or superchargers). The increased flow demands created by the forced induction could damage the valve and lead to engine damage.

I think they mean if you were to put the bypass foam piece in the intercooler piping portion; pre-turbo would be perfectly fine.
