Default VF11 turbo

I have a VF11 turbo, I have tried to find out what the wastegate spring is inside for the pressure of the boost but cant find anything on it.
Does anyone know what a stock vf11 pushes ?

thanks !

yes, it is indeed. The car can 9ish PSI (maybe 10-11 peak) but wastegate pressure was 5-6ish pounds.

So you're all wrong. I have a vf11 on my 92 ss and its piped into a Manual boost controller and it will make a steady 17-18 psi at fully closed waste gate. Factory waste gate settings is 5-7 psi.

One thing you have to keep in mind though is 19 PSI through a VF11 is no where near 19 PSI through VF48/54 ECT!
