Hey guys, what breathers / catch cans are you guys running other than the LMR option?

Any data? Pricing? Pictures?

 

From what I've seen it looks like the LMR and Lashway are the two best options out there. Other than those the catch cans seem to be pretty basic. Both the Lashway and LMR have a pretty comparable design and price point. This is all speculation. Not sure if any one is better than the other.

 

I looked for one for awhile because I was blowing some oil on my boosted z51. I really didn't want to do the lmr because of how much it was but I couldn't find anything else I felt comfortable with. The lmr is worth the money, I have a powder coated black one it looks really nice and solved my issue. Its expensive but money well spent imo.

 

Yea I agree with you, but the whole weld on connectors is just a huge turn off for me. Did you find another solution for the connectors?

 

No it wasn't a big deal for me. The valve covers are easy to take off so I took them to my tuner and he welded them for like $20 while I waited.

 

I also wasn't a big fan of having to weld the new connectors. Check out Lashway's, similar concept, no welding necessary.

 

Looks like lmr is now offering snap on connectors as well

 

Here is my Rx Stage 2 Catch Can and
1LE Style Clean-Side Separator.

Installed during November. Not many miles since.
I do not smell fumes and the intake is clean.
The can does not have oil.
I can not give you a recommendation, until spring.

Okay.....now it is spring....no oil in catch can after 700 miles.....
No fumes in the cabin, I can now recommend....
Now it is fall, after 3,000 more miles, I have collected 5 ounces in the catch can.

I have been running an RX catch can also. One thing is most catch cans are not created equal. Their shop is near me and when I went there they showed me a cutout of about 15 different brands of catch cans and their internal designs. A lot of these were nothing but a hollow can with tubes.
The RX design was the most complex by far.

I have been very pleased with my setup and would definitely recommend their setup.

 

I noticed that. Wonder if it's the same price point.

 

Lashway has a great looking product for sure.

Someone thst runs the LMR or Lashway tell me...how bad are the fumes with it releasing to the atmosphere all the time? Is it unbearable?

 

I have the Lashway unit on my car. I am getting fumes in the car at low speeds or at idle. I was instructed to run my HVAC in recirculate whenever possible and it helps considerably. On the highway at speed I'm not noticing anything. My new build (forged 416) has approx 700 miles so far. I haven't had a chance to check to see how much oil is in my catch can but intend to do so as soon as my car isn't held hostage in my garage due to weather. I have added 1 quart of oil to the car since it was completed. Be good to know how much was consumed vs in the catch can.

Ron at VR mentioned adding some hose onto the breather outlets and basically remotely locating the filters to see how it works. If they could be moved further away from the firewall it makes sense it could reduce the venting into the cabin. Next time the car is on my lift I'm planning to find a location to relocate the filters to.

 

I've been talking to Ron about my little experiment to relocate the filter(s) by way of using silicone elbows into a T, and running a 1" line out the bottom to a filter. This would work for both the Lashway and LMR cans. Can you give me a measurement on the filter outlets on the Lashway? For reference, the LMR outlets are 1.5" OD.

In short, on my build, the fumes are absolutely awful (with recirc or not). If you open the hood to look at what it's putting off at rev, or even near WOT, it's a ton of smoke. My filters are yellow like they were stained with nicotine for 20 years.

Now, I love the can, and I love the design, etc... I just have to get those fumes away. I've been working on this design on and off for about a month now, and so far, it's going very well. I've found a good source for the silicone elbows and aluminum T adapter. It's been more of a sizing question regarding -12AN (3/4") vs -16AN (1") for the output line running to the bottom of the bay. Not sure just how much is really needed, but if you factor max flow on the 2 -10AN and 2 -6AN, you end up with around 1". Now I doubt that would ever occur (we're talking blow-by here), but I've picked Ron's brain about this for a few weeks now going back and forth. We're leaning towards the -12AN option.

I was planning to document the design and give a part list, etc. The total project with a proper K&N shielded filter at the bottom is looking like less than $100 for everything, and the bulk of that is the 3/4" silicone hose and lower filter. I've sourced the upper adapters at a very reasonable price. Just have to do a little cutting on the silicone elbows.

 

Look into the mighty mouse cans. I've had Elite and RX, and just put a MM can on this weekend. Best setup I've had.

 

What turned you away from elite and rx? Just curious. Shoot me a pm if you want.

 

We are supposed to have good weather Tue/Wed so I'll drive it and get a measurement for you. I need to check the oil level in it anyway.

 

Th OD of the outlets on the Lashway unit is 1.25"

Nothing came out of my drain wheni checked it yesterday however the drain isn't completely on the bottom. We did a little more racing last night so today I intend to remove the unit and see exactly how much is in it or at least unbolt it to get the drain at the lowest position possible.

 

Curious why you guys don't route the PCV lines to the air filter box per the ECS instructions. I've got 3500 miles on mine now and it doesn't get any oil in there or have any smells. I think it's good to have a little suction on the crankcase too to keep water vapor out.

 

Theta,

You might want to contact RX and ask for the owner. He has done significant research for years on this issue. As an engineer you will be impressed with his knowledge. It might save you from having to re-invent this particular "wheel".

my personal experiece with this layout was oil EVERYWHERE in the air box, dripping down the undersides of the car, on the air filter, in the intercooler in the blow off valve, and it stunk. previous owner had a second air filter just to deal with this issue.



you are very lucky, i would encourage anyone to take a look for themselves vs. assuming everything is a-ok.
