Stillen Air to Air setup

Interesting. I have a series of questions though.

Are you going for CARB approval? Why are you recircing your dump back into intake and why are you plumbing into the valve cover?

Is your Y pipe sitting vertical and you are going to have one pipe underneath the other? Looks like that would be a long split.

Why do you have the BPV/BOV after the IC? This is going to pass hot air from the SC through the IC so at a standstill, any light, and such it is going to pre-heat soak your IC, isn't it?

Don't need to go for carb approval. Intercoolers on gas motors are not regulated and can be added, modified, or removed without issues even if the kit is aftermarket, so if you wanted to run an air to air intercooler over the supplied air to water setup its perfectly fine. However you would not technically be able to change the tune but no smog tech/bar tech can see if the tune has been altered so who cares.

Its funny how many things are not carb regulated in California.

Edit oh you would have to recirc the BPV as opposed to letting it vent to atmosphere but if the tech can't see it venting visually, you're fine, the smog techs can not legally tear apart your car just to inspect it, so if its out of sight no sense in worrying about it.
