I am making a low boost v8 setup for my rx7 and have a buddy who has a extra vr4 stock bypass valve. how much can these hold before they start to leak?

Re: stock bypass valve?
the 305 is a fairly popular swap into a RX7, Stock BOV's are good for at least 15psi, not sure what their max is.

thanks that should work great! and why a v8 in a rx7? 4.1 more liters to work with than a rotary. more displacement mean i can push a bigger turbo. plus a v8 has a few things rotaries don't. torque, MPG, the ability to survive detonation, etc.............

Re: stock bypass valve?
My stock bypass valve started leaking at stock boost (12 psi) around 50k. You can tell it is leaking when you floor it and hear a honking like a goose is under your hood. But you mentioned a low-boost setup, so you should be good.

the 3/S stock bypass valve is crap, if you want a cheap solution but good quality, look into the 1st generation dsm bypass valves. They're made of metal instead of plastic and will hold the pressure.
