VTA or Recirculating Catch Cans - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Which one is best? I've read so many reviews and what not and it's hard to find real evidence of which is better. What do you suggest and what brand?

JDM4E · 10-23-2016, 08:15 AM

Personally I would go the third way. Catch the junk and manually drain it when oil change.

Spartarus · 10-23-2016, 08:50 AM

Just vent it.

OEM's used to vent it, the only reason they don't now is emissions regulations, specifically regulations about unburned HC's. They used to just call them crankcase breathers.

The boxer engines on airplanes and old Porsches VTA too, just irrelevant FYI.

Ask any auto engineer if PCV in any form is a good idea, they'll all tell you it's a terrible idea, and its just there for emissions.

A proper VTA will let nasty things like water vapor and blowby evaporate, let oil stay in the engine, and let crankcase pressure equalize with atmospheric pressure so seals don't blow out.. Nothing should build up in the can. Zero maintenence.

Its the only sure route to keeping oil out of your intake tract where it doesn't belong.

Great information! Thanks.

Do you have a preference on brand?

Depends on your preference for aesthetics and maintenence, but I wont say too much because I have one for sale and anything I say could be misconstrued as a shameless plug for my ad.

Haha.

I'm not a picky man. I was looking at the FBM can but was unsure about others

Well, now that you know my opinion is biased, I can say I like the MAPerformance can the best... The one they include with their turbo kit. That's why I had them make me one.

Annnd now I don't have an FRS to put it on.

What kit did you run their can with since you didn't use their turbo kit?

Luftwaffel · 10-23-2016, 03:57 PM

Check out the new Velox AOS. Can operate basically however you want it to.

Embarrassed as I am to say it, Speed By Design.

Not a decision I'd make again. The build quality and engineering were unsatisfactory for me. Not bad, just not up to my standards, and nowhere close to OEM standards.

I used the racerX can, also a very good option for recirculated cans.

Got the MAP can intending to switch to VTA, and a different turbo kit, but never did it. Sold the kit, then later sold the car.

VABeachBRZ · 10-23-2016, 04:13 PM

Thanks for the replies. I guess I'll look around for more VTAs

Also racerx has the option of making their cans VTA 👍🏽

I'd highly recommend the velox can great build quality amd can be run in vent or recirc.

Also great quality are the Radium cans, I swapped my Radium cans for the velox kit due to my supercharger interfereing with the Radium cans mounting so that is something to think about.

I'll look into the velox
