SR Owners... More HP Easy Mod... Catch Can Setup

[SRpetey]

so what works better? putting the line before the maf or after? and will it work if the top fitting is welded on the side instead?

It depends on what type of catch-can system you are using... If you are using an open catch-can system (vented can), then I wouldn't plumb it back into the intake tract at all. I'd hook up your hoses to the VC and leave it like that, it'll vent itself. If you have a closed system(non-vented can), I'd get the special fittings needed to have it plumbed to the exhaust, after the turbo. The exhaust gases passing the fitting will create a venturi effect and will suck all that stuff out of the head through the can and into the exhaust. You can go before the turbo too but, that means you're sucking all that crap from the head straight into your turbo. Personally I wouldn't want it setup that way...

I run a vented can that has 2 hoses from the VC and a drain, that's plumbed back into the upper oil pan, so anything that does collect in the can goes back into the motor.
