The PCV is closed during normal operation, and is operated by direct line to manifold vacuum. This retains full stock PCV system function while increasing total system capacity, protecting it from boost, and relieving any crankcase pressure.

The RACE can is an open vent catching whatever liquids comes from the crankcase.

It is completely passive, not connected to your incoming air supply at all, and PCV is completely deleted.  That means zero blowby fumes comsumed by your engine, but that also means the fumes will go to your engine bay and sometimes, the cabin. *sensitive noses beware*

The DRAFT can hooks up two ways:

1. This is spliced directly in-line of the stock PCV system between the intake manifold and stock pcv return.

This catches oil normally consumed by the PCV (dirty side) and gives some crankcase pressure relief.  Because it relies on OEM PCV regulation; HP capacity is limited to 'near stock'.

2. For those that want to keep the breather closed when possible, but do not want to or can not hook up to the intake manifod; 

the PCV system is completely deleted, and this can is connected only between the engine and your main air filter.  This is high flow and can handle a lot of HP but also recirculates more of the fumes directly to your engine as part of total air supply.  The amount of DRAFT can be influenced by clean side fitting selection and vac/restriction generated by your air filter.

The PCV can is the max effort bells and whistles fix for people who want a PCV system and high HP.

Clean air still comes into the crankcase to filter out particles/fumes/moisture during regular driving and is constantly scavenged back out by intake manifold vac (just like stock).

We block boost from entering the can / engine, we catch the oil before it is consumed, we relieve any crankcase pressure created from high HP, and we recirculate very little of these fumes during full load, so  the engine can make power with as much clean fresh air as possible.  Because of the special configuration; we are no longer 'restricted' by the factory system, and can connect to the crankcase with full-flow or multiple fittings to accommodate high hp.

You may notice Hoses are not listed or shown on any of the can configurations.  This is a personal journey you must take with your own car to determine the length, type, color, shape for your exact install. I specialize in custom catch cans, and while I can help suggest what hoses to use I do not make or supply them exept in special pre-determined cirsumstance, as they are also most likely custom.
