At what point would it be necessary to run two BOV's? I am building a blow thru bbc with an F3 Procharger. I only plan on running 20 lbs of boost, would one red one be enough?
Thanks

Most people I know of run one on the "hot" side & one on the "cold" side especially with an F3.

YOU CAN SAVE SOME MONEY AND RUN ONE OF THE BIG VORTECH ONES. THEY FLOW OVER TWICE AS MUCH AS THE PROCHARGER ONES

Mike G is Right

There is no need whatsover to run 2 valves if you choose your valve wisely. The BV57 Vortech outflows competitors valves by a disgusting margin at the same pressure ratios. Ask Petty, Baudier, Urist, Murillo...etc

Honestly

None that I can think of. Unless you just flat out dont like Vortech. LOL. It's a really nice piece and I'll think you'll be completely comfortable with your purchase should you choose to go that route.

Thanks again. Would there be any reason not to run the Vortech BOV?

Toss a pair of JGS 56mm on it and be done.
At only $220.00 each it is cheap insurance and they have a larger inlet than the Big Red P/C valve anyway.

I've split 4 inch aluminum discharge tube like a bannana while peddeling car
So was this an anomaly? What other ill effects are happening to require the need for two BOV's?

The reason I'm asking is, I've been running a F3R for probably longer than most and only run one BOV. I've run as high as 40 PSI on gas (consistantly 35-38 and no intercooler and have never seen a need for two. But mine is strictly drag racing.
Not arguing the point, just curious what is causing the need for two.
Is it more of a thing with using an intercooler, EFI, street driving or....??

Blessings..........Ron.
