(2) Race bpv vs. Mondo or Big Red BPV I am going to run a Vortech Ysi with a cog drive in my LS3 (it has forged internals with 9:1CR).
I have searched and cannot find much of anything referring to using (2) bpv. I am not sure how many PSI I will be running, but let's use 20PSI as the upper limit for this question's sake.
Am I fine using the two of them or should I get a Mondo or Big Red Procharger to use instead? If I end up using both of them, where should I mount the second one? Near the first one or on the pipe on the other side of the intercooler? I will be venting to the atmosphere regardless of set up

Didn't know anyone ever used two bpv.... I have big red open vented to the atmosphere. It sounds pretty bad *** but it's definitely not stealthy. Most people put it between the blower and inlet of intercooler.

I have found a couple of instances where 2 were used but they seem to put one before the intercooler and one after. I couldn't find any instances where they were used on the same pipe (pre intercooler).
I was told to put them on the same pipe and I believe there is room to put them side by side. "T" the vacuum line between them and run a larger hose from the "T" to the vacuum source.
In theory it makes sense to me. Two slightly smaller bpv that flow 320 each vs. 1 bigger one that flows 500+. I don't know if one is better than the other but I think it will work. If if doesn't, I'll sell the two valves and buy a new tube and either a mondo or the procharger.

I'm gonna run the two and then go to a big single if it doesn't work. I am thinking two with the cog drive is going to be quite loud. I'll have to coast into my garage every night after work to keep my wife happy. I might have to start the coast at the corner even.
