I switch from a f1a to a gt91 turbo and I am keeping the big red procharger bov. The guys that run this setup, are you running the vacuum line from the valve to intake like a supercharger, or not using it? Does it open when you let off the throttle still? Thanks for any help guys.

vacuum lines are the same, and it is open when you're not on the throttle. Its a bypass valve, not necessarily the same thing as a blow off valve

IF I may, id like to add to this discussion as well.

Why do some turbo guys run them as well? OP, if you dont like this, ill be happy to remove it. thanks.

I think they are able to vent more air than a 60mm BOV. Which even though is split second, reduces the backpressure on the compressor.
