Catch cans: what are you running?

The others don't have a relief valve to fail and would blow the seals if they blocked up.
The valve is there as a safety precaution in case the system gets blocked, that is the only time it would operate and then open to vent the crankcase breather to the atmosphere.
Mine has been on for almost 40,000km and the relief valve operates freely, I check it but has never opened because there is no oil mist where it would vent.

If you are driving for economy, very little oil will collect to the point it makes very little sense to use one.

I have used a Radium on my Lotus and Hyundai. Chose it not only because it was designed for track duty but because radium did PCV flow testing to make sure, air flow worked properly under vacuum. PCV systems are integral parts of engine design and many people seem to ignore or not understand how they work. Impede a PCV system and you can actually create engine problems over time along with drivability issues.

I would only use a can that was tested by companies who build the can specifically for the car or use it for track duty.

I am going to be doing a DIY with the Radium can this week.

Still doing the DIY on the radium catch can?????

Hopefully somebody here can help with this form or go by and have them take a look. pm me if so and i will make sure they know you are coming.

I dont know if everyone on this sub forum has seen it on the forced induction forum but we designed ours for NA and forced induction apps. It also comes in 2 different mounting positions depending on your setup:

It is garbage. It is a completely empty can. Cans like that will pick up a small amount of oil but the vast majority blows right through.

it has one line in and one line out, this would greatly reduce the amount of pressure to release from the engine. That filter on top im guessing is for pressure relief because im sure it could barely do that, looks like a 3/8 (.375") inlet to the filter. Ours uses an 1.50" inlet filter.

Here is the full Radium Catch can DIY including plenty of technical info:
http://www.ft86club.com/forums/showthread.php?t=21079

I don't want to turn that thread into an argument or debate.

But I wanted to finally jump into this thread to raise some questions.

1. The D3PE can looks amazing for those who run FI setups and the battery mounting option is a near perfect location. My only concern is venting into the atmosphere, and really it's not much of a big deal if you are running FI and want to keep your IC clean. Really like the can, be nice to see it powder coated black. Would like to see a closed system with baffles. Using the Radium with the Exige intercooler, I never had any oil build up on the IC pipes or inter cooler. But this can is a spin on that completely eliminating any risk of oil or contaminants getting in.

2. The ProVent seems so overly engineered for the FR-S/BRZ and then you have to replace the oil separator which means you have extra cost in maintenance.

3. Saikoumichi probably the best bang for the buck. My only complaint is the one piece design you have to rely on the drain valve which can make for less flexible mounting options or if the valve fails you get leaks.

4. Crawford, I just have so many questions... Where is tech data on internal design? Any cross section images? Why would you want the oil blowby back into the block whats the advantage of that aside from not having to drain the can? Flow testing?
Their website says, "Results not Rumors" that almost sounds like snake oil, no offense and for $319 I want more information than just, "Trust Us" The mounting location is also awkword.

5. Moroso - Just a generic catch can. Cheap option for sure. Needs a better mounting location.

6. There has always been talk of mounting the can on the engine, so that can and PCV lines are subject to the same engine vibration. Mounting the can on a fixed location does not allow the can and lines to move with the engine. I have found no proof one way or another, but always believed that the can and lines should also remain on the motor.

7. Less is more. The more ports, seals, valves make a can more prone to potential vacuum leaks.


Discuss?

We will never release a closed system due to the fact that it is not the best way to do it. From all our racing experience this is best way based on our data we have collected including pressure readings from the block via a map sensor on Pcv line.

As for color we can't offer powdercoating on our products that have AN fittings, this is due to the fact that powder coating actually adds a thickness when applied, we do offer some other catch cans anodized black as that process the color sinks into the metal and dosent add a thickness. We didn't offer this since it would raise the cost but if say 5 people got together and ordered at the same time I can do it for a little extra.

Our can also has provisions for a drain back if the customer wants to weld a bung on the oil pan to eliminate the draining that is needed every so often. But in reality this is not really needed.

And I'll go ahead and answer your question about the Crawford can, the drain back is purely so you don't have to drain it.

Hey guys I've been talking to Saikou Michi for a catch can and i'm going with a single can. Does anyone know the correct inlet/outlet sizes for are car?

I was trying to get the same info but couldn't figure out that form he sent me, it's a few posts up.

That's strange I didn't get that in my email from him. Maybe because i'm planning on going with the Stage 1. He did mention 1/2 was his guess but I should confirm it before tho.

Someone with an FRS/BRZ let him check it out for us please!
