Catch can efficiency

They make 120 dollar hemi catch cans, and they make just universal catch cans for 20 dollars. My question is will the 20 dollar one work just as well as the 120 dollar one. I can post links if that helps.
Thanks

Re: Catch can efficiency

Im curious about the same question.

After all, Im not trying to impress anyone with how shiney or expensive my mods are...I find cost efficiencey and functionality far more appealing.

However...if the extra 500% in price gets you something meaningful...then that is also "cost efficiency."

So Im wondering what intel those who "have done"...can share with those of who "might do."

Re: Catch can efficiency

Youve got a 50k-70k vehicle...the billet tech can is nice, customizable and they support this forum. No brainer for me. Plus they look cool.

Re: Catch can efficiency

I'd have to see the $20 catch can; I have never seen one.

The billet tech is a well-thought-out piece of gear.. there may be more to a catch can than you think.

Re: Catch can efficiency

Just a couple things to read/understand from those that are in the know about catch cans:

From another Jeep forum, a quote from Mike at Diablosport, the tuner manufacturers:

"No, this is where I comment on lost power due to oil contamination in the intake tract/combustion chamber. I will assure you that after having seen as many logs of as many HEMIs as we have here at DiabloSport, not to mention the numerous HEMI vehicles we have had on our dyno for R&D, I can say, without a doubt, that the HEMI's PCV/Oil Vapor control is the worst of anything we deal with. All you have to do is pull your intake manifold to see the puddles of oil collected in there, and realize that it eventually gets in the combustion chamber, and oil don't like to burn, thus, detonation occurs.

There is no gimmick here. HEMI's have KR issues. The KR issues are 99% of the time contributed to by oil contamination in the intake charge, reducing the effective octane in the combustion chamber, and leading to a loss of performance."

Plenty of people have seen solid power gains on even stock vehicles when getting rid of an oil issue by adding a catch can that works properly.

This "Bible" is from Arrington Performance.....Hemi Specialists:

Re: Catch can efficiency

I didnt mean to imply that catch cans werent valuable. I have two on my airplane, but in aviation they are called "Blow-by oil accumulators" and "Catch Cans" are what hangs off the bottom cylinder of a radial engine to catch the drippings that let you know the engine has oil in it. hahaha..... but this aint aviation.

I recognize the value of the catch can on the hemi...based on multiple threads of deplorable oil consumption.

My only question is...assuming that there is a $20 can option...is the $120 can 6-times better at doing the job? Its not about if I CAN spend an extra $100 for a can. its about if the more expensive can is WORTH the extra expenditure...does it do something that the less expensive can does not do. Yeah...its an expensive vehicle...but I didnt get to a point where I can afford the pricey buggy by making emotional or ego driven decisions with my money. I CAN run Perrier Water in the washer fluid to prove I have money....but if it doesnt do a better job, then its just a waste of dinero.

Looking cool has its place...I agree.

But Im not gonna be hanging out at the corner stopping passers-by and saying: "Hey, buddy...wanna see something cool? Come look under my hood." hahahaha

Again...if its worth it...awesome.
However, If it does the same job....I dont buy hype. I dont know whch is the case...and neither does the OP.

Thus the simple question....does anyone have experience with the range of catch cans....and is there a difference in effectiveness.

Its just a question...not a witch hunt.

I dont think the OP and I know that I am certainly not trying to make anyone justify their decision to pay more, when a cheaper option MIGHT be available. We are just wondering why so that each of us can make informed decisions.

Re: Catch can efficiency

I see the link to the ebay catch cans, but no detail about the innards.

The BT can has a metal-wool filter on the out-going port that (as far as I can tell) catches droplets that don't just fall into the can..

the ebay one doesn't look all that easy to empty either (though, truth be told, the BT mounted to the PCM bracket is no joy to empty either..)

so, dunno. Would need to hear from someone who had actually used the ebay item.

Re: Catch can efficiency

I purchased and installed a Moroso catch can some time ago. The reason I chose this one was the ease of emptying it. The extra cost was worth it to me. See attached..........

Re: Catch can efficiency

The BT can is super easy to empty. Takes 1 minute.

Re: Catch can efficiency

Hi,
For what it's worth I have used both a cheap ebay type can and a BT. Both cans appeared to scavenge about the same amount of oil. This was not S controlled comparison just looked around the same 10mls per 1000kms. This on the 3.0l Diesel.
For me the BT can is more elegant and easier to mount and empty.
Pete.

Re: Catch can efficiency

I wouldn't go cheap on my truck so i prefer the BT. Yes it fits tight under the hood but still easy to empty. After using other well known brands and BT and the amount of oil that is collected and not going into my intake, i would gladly pay that $125. That is if you plan to keep it, if you will trade within 5 yrs then its a waste.

At the end of the day if your curious, its only $20 so give it a go and if you no likey, then buy the good stuff.
