Blow off Valve, Recirculation setup

[cbileske]

Just a quick question.
I have a HKS SSQV Blow off valve on my RB26, I would like to recirculate the valve now.
Can the recirc. pipe go basically anywhere in the system after the AFM's? or does it have to go in front of the turbos?

as you can see from this from this pic, taken from Josh's build thread, the recirc pipe comes after the MAF and before the turbo

but you don't have any recirc piping left ? thats going to be a PITA to plumb, all custom

though i have the plastic pipe that runs behind the intercooler, from driver to passenger side, for sale, since i just took it off a week ago, since i'm not recirculating my twin SSQV

I still have all my stock piping, I was just curious if it had to go all the way over to the intake side. I could just run a 1'' line "or whatever the size of the adaptor is" all the way over and weld a fitting into the aluminum piping.

well it has to go just before the turbo, since it will replace the incoming air,
when it recirculates, it keeps more outside air from coming in through the MAF, since the pressurized air being recirculated has already been calculated by the MAF and is still in the system

if you place it anywhere after the turbo, the turbo will still pressurize more incoming air, plus the recirculated air = boom, too much volume/pressure

ok, thanks alot. I will recirc it to the turbo side of the car. perhaps i will t off of the balance tube or something

BOV question, what to do?

I know Im likely going to be told to post elsewhere but can anybody help me with my question about a Blow off valve? The car is pretty much stock with exception of full exhaust and clutch. I just installed a boost controller and want to put in an aftermarket BOV. Does anybody have any pics of their RB26dett motors with aftermarket blow off valves? I have seen one car with a bov just after the intake manifold and he kept the stock ones there.?.? u can also email me at denisdupont@hotmail.com. Thanks. ps i have an ssqv bov here was hoping to use it.
