If so that makes more sense to me and also makes it easier to fit
Yeah, basically! only thing is there are 2 breathers and youve gotta get them into 1 tube to your car (using japspeed) so im gonna try get some more pipe + a T piece from a pond shop or something lol!

But the 2 rocker cover breathers are already paired through the pipe on the front of the intercooler so connect that to one inlet, the PCV to the other, block off both inlet breathers and bob's you uncle
Do you have to vent off the can's? As where would the excess pressure go from the breathers?
Also, I've read a lot to just plug the PCV outlet. Andy Forrest recommends this as well.

That would enable you to vent from the other catch can outlet if you blocked all of the inlet hose connections. I recall on my cavalier just blocking the inlet and venting that hose to atmosphere via a small K&N or similar
Is that all there is to breath.......the PCV (which I'm going to block), then the rocker breathers?
So then I can tee the rocker sides together, and use one port on the Catch Can....and vent the other like you said.
I'm going to have a FMIC on, so won't have the OE rails on the TMIC.

Is that not what this pipe on the front of the intercooler is doing. Taking a breather feed from each rocker and running it down into the inlet hose

Shoot me down here, but fitted one of these on my old MR2 tubby, and a lot of similar debate on there.
I had mine plumbed in so that it took the PCv feed into the can, which then just had a breather on the outlet. Then blocked up the pipe into the intake, so no oily mess got in there.

Just to add more confusion, I looked at how Slowboy had fitted Wiley's, and it looked like they had the plumbed the turbo side rocker to one outlet and the hose coming from the other outlet ran across the engine and somewhere under the nearside of the engine - I didn't have a light so I could see where it terminated
I hear what you're saying Grant, but the way I understand it there's 2 independant feeds to the inlet, both of which have the potential to feed gunk back into the inlet system; the rocker breathers and the PCV. As I see it both of these need to be diverted from the inlet and the obvious place is the can.
As I said previously, I just vented the whole system to atmosphere on my V6 Cav. I also vented to atmosphere on my old crossflow fiesta. If the can is collecting the vapours, I'm not sure of the need to vent
This is why mine is still mounted in the garage

Hi, I have been using this can for a while on my GC8 (track only) it was a great kit and came with all hoses, fittings, battery braket etc, the new model has 4 fitting, I vented mine to atmosphere (little K&N filter)
DIY Hyperflow Catch Can Install - Rexnet Subaru Forums I bought mine from TUSPEED over here in OZ.

My friend has just fitted the Hyperflow one. Quality bit of kit, but not cheap. His has 4 fittings on. You can't really use the bottom two can you other than to vent, as there isn't any sponge filter, where as there is on the top two.
Can i just block the PCV or whatever it is? or does my crankcase need to breathe? if it needs to breathe i can just VTA right? and also VTA my catch can.
I did mine by....
Pluging off the PCV, then using a tpiece put the rocker breathers (already paired) into the T piece along with the crank breather. Then that pipe into the catch tank and on the other side of the tank have a hose with a little filter.
