im looking for insight on a catch can set up for high hp miata's(400hp +)
specificly i want to know if i can remove the pcv valve and run a 10an line to my catch can. and two 10an line off the exhaust side of the valve cover.
does any one on here run something like this??

yes the less pressure in the crank case the easyer the pistons move= more power,my boss's big block runs a vaccume pump,he picked up like 20 crank hp on our superflow engine dyno. and with high hp cars you dont want to run back into intake, turns every thing black and nasty, turbo cars blow out alot of oil mist.my car is gonna be pushing 400hp, it is a purpose built race car, built to formula d specs. the drft in my name is cause i drift, i live in ct and my car is a na. my big question is will i have any negitive effects of removing the pcv valve and just venting that to the catch can.

Haven't seen that on any Miatas- but no reason why it can't be done. Most higher boost applications I've seen eliminate the pvc just because it becomes more difficult to prevent the valve from leaking. And most of those cars are daily driven so the pcv valve serves less benefit. IMO a turbo'd daily drive benefits from both a good vent system under boost and a good pcv under normal driving.
I've never heard of drifting, but it sounds like fun.

all that check valve is doing is keeping presure from the intake manifold from blowing into the valve cover right, so if you remove the hose from the manifold and run it to the catch can there is no pressure and still a vent

The turbo 2.3 Ford cars back in the 80s had a breather on the valve cover that would suck into the turbochargers inlet.. My guess was for this very reason, but they could've been thinking more along emissions than anything else.

Technically with boost on the intake manifold the PCV valve should be shut iirc, so how you gonna suck out anything unless you reroute the PCV to the inlet of the turbocharger?
