Coolest Oil Catch Can

Sh0velMan

How is this not legal for 'the track'? Also, please clarify what 'the track' is.

You just provided a direct line for oil to come out of the motor and onto the track. All systems must run through the motor first so it has a chance to be 1. Burnt up in combustion and 2. Can stay in the motors cylinders if a catastrophic failure should occur; like a stock PCV system. When the motor goes you will flood the track with oil and if I wreck because you have an illegal setup and tech missed it I'd kill them! There are no vent to atmos or re routed crank and valve systems aloud. A AOS is aloud on a race track because it will catch oil and it's basically plumbed just the OEM back to the manifold. A catch can is not aloud except on a drag strip because you can't exhaust much blow by in <20 seconds vs 20min on a race course unless the can again is plumbed back to the manifold.

All my extra cowl space is where my vacuum manifold, boost controller, all vacuum plumbing is tucked! I am tight on space just about everywhere right now.

I actually like the look of this one. Do you think this would be overkill if I got two of them for a n/a car?

Hmm never heard of slash cuts being illegal at most tracks, i mean if you have a blow up chances are oil is coming out of your car from many places including LOTS of it coming out your exhaust. I have had my windshield sprayed a couple times already from cars that were just in crap condition and they pass tech. I KNOW they are legal at just about every dragstrip and i say "just about every" because there may be a backwater strip somewhere that's banned them. and most scca and nasa classes don't let you touch the pcv at all except for the addition of a catch can, but you have to use factory hose routing and no external filters.

edit: i actually spent a couple hours reading through different class regulations here and there and it is either no restriction or oem only for the most part so it all depends on your class and tech. also unless you have a SEVERE problem, there isn't going to be any real oil coming out because hot oil and air mixture + header collector or downpipe temperatures = burning oil fumesresulting in some carbon put no oil per say

True oil will come out but again coming out just the exhaust vs coming out the motor then the exhaust is the difference. And I've never seen track or drag strip rules, its in the race organizations rules.

you mean like track day club rules? I know most hpde days don't tech anything past safety belts, helmet, tires, and brakes. If you are talking organized racing classes most class rules are either it needs to be stock or no restriction. There are no restrictions on pcv in any TT class for example.

Can we have a simple up/down for the benefits if any for N/A 370Zs?

Pros- cleaner intake tract. Cons- cost, under hood clutter. Is it necessary? No.

So what we can do here for TT setup?

Im interested in purchasing oil catch can with redesigned PCV for TT application if some1 came up with.

G37sHKS,
I actually was PMing Sh0vel about this a few days ago since I am looking to run one in my GTM TT when I get it all installed. This is what he said in his reply;

So, for an FI setup, you would want to plumb it a little differently. Basically, put a breather filter on the fat connection (back of the cover) and put the front connection into the catch can with the can outlet dumped into another breather filter.
Then cap/plug the manifold nipple (sticks out the front of the manifold).
This is the only way I see to do it that will relieve pressure build up from blow-by and still catch the oil. Crankcase scavenging at non-boost times will be a little poor, but most agree it's not a big deal. This is the really simple way of doing it.


Now the more complicated way;
For my own car, I would probably set up a pair of check valves on the cans.
Basically one between the manifold and the can that only allows air to pass IN TO the manifold, not out of. Another between the can and it's breather that allows air OUT but not IN. Then I'd plumb the fat connection (back of the cover) to the inlet pipe after the MAF (if a connection is available there).This way, you maintain the excellent scavenging off boost but won't have issues while on boost.

I replied and am patiently waiting for him to finish a diagram / parts list he's working on, he mentioned it earlier in this thread.

<slightly off topic> I ordered my Saikou Michi catch cans today </off topic>

Are catch cans a worthwhile thing to have to keep carbon deposits down in the engine, FI and NA?

Probably not, but I'm getting some anyway as I am setting my car up for some track days.
