Buschur's Vented Pro Catch Can

[TorqueWrenchUSA]

My Miata I've tossed a rotrex on and don't drive very often has a vta can on it and helped a bit with oil issues. And it helped a bit with idle tuning. Aside from that, one drawback I noticed is I get a rather hydrocarbonous smell when using the fresh air vent. Something I don't particularly enjoy.

After a good drive and then coming to a stop at a light. Do you smell the vta can coming into the cabin through the HVAC system at all?

Yea I'm deep Westside of Cleveland. So Cuyahoga County is one of the lame 7 that has e-check.

Same E-Check here in Lorain County. They have never opened one of my hoods during many tests. They check underneath with a mirror for the cat and check the CEL. Hook up a OBDii cord to test. On one occasion when communication failed they did a test on the rollers with a box they placed on the hood (to check RPM?). They also check the gas cap which I am not sure how that will work on the EB Maverick since there is no cap. Most of the techs have no idea what they are doing and the test is worthless anyways.

I can't believe I'm going to waste my time......

You do realize anything that is coming out of the vent on the catch can would typically be burnt up in the engine, contaminate the intake cycle, cause the engine to be less efficient and use more fuel anyway, right? No of course you don't. You also think your hybrid gets clean free electric straight from Greta's farts too, right?

Dude, I feel for you. You are in a tough industry considering the very polarized opposition to performance. I would be very hesitant to make my livelihood based on performance development considering the EPA persecution of such people, but keep it up. A thank you from me for pushing forward with research and development in advancing performance. Proof is in the time slips.

I appreciate the time you took to respond. I am in an emissions state so I may have to pass on the vented.
Have you monitored the vac levels on the Maverick when not in the throttle?
The few reviews I had seen with back to back testing had the vented cans staying at 0 vac/boost compared to -20 vac with the sealed can.

No, I haven't and I don't believe any company on the planet has done that testing on a Maverick.

The only place I see having an issue with this is a visual check, it causes no check engine lights and has no effect on the actual emission standards the truck puts out.

For the Greta's in here, what it does do is keeps the foul oil and contaminates from being burnt in the combustion cycle, which isn't clean at all, increases milage (read BURNS LESS FUEL EMITTING LESS POLLUTANTS INTO THE AIR) and increase horsepower. Anytime you get rid of deficiencies the engine gets more efficient, this means you burn less fuel, the engine runs "easier". Crankcase pressure is one of those things that do that.

Thus the term "CATCH CAN". It catches those evil hydrocarbons in the PCV system before they are burnt into more pollution. Once captured, you can dispose of the bad stuff more environmentally friendly. Really this is a green initiative that has a positive effect on engine life and performance.

The can catches the oil, unburnt fuel, contaminates in the can itself. The vent on the can vents the crank case pressure, which I am sure carries some of that crap in it but the absolutely majority of it is caught in the can. The cans are packed with a stainless steel wool material that helps all the "liquids" cling to it and stay in the can. The vent is on it to rid the engine of the crank case pressure, which makes the engine less efficient, that pressure is UNDER the pistons and fights the pistons from coming down on the down strokes.

Exactly why I asked if you’ve done the comparison. You own a Maverick and produce both products. Wasn’t sure if you were monitoring boost and vac levels.
All reviews on vented vs sealed came from different platforms.

The logging to monitor crankcase pressure is more involved than looking at just a boost/vacuum gauge. The running vacuum, (driving down the road/idle) stays constant when logging, so the engine produces vacuum as it normally would, it's measured in the intake plenum (typically anyway) as is boost pressure. I thought you comment was asking about crank case, looking back I should have known better.

So to answer it correctly, the engine still produces the same vacuum readings as it normally would, if you did a scientific log back to back with and without the vented can, it may even end up slightly higher vacuum readings with the vented can.

The vented can only drops the pressure in the crankcase.

Thanks, I appreciate the response.

David, I had trouble finding the vented pro catch can on your site. Do you have a direct link?

Would this not balance out, since it would also "help" pistons on the up stroke?

So here is a question. Lets say someone lived in a visual check state And wanted to stay legal. How hard is it to reverse a vented catch can if one wanted to use it "For Off Road Only" while on the track?

567-424-0471 if you'd like to call or just order the standard can and put a note you want the vented Pro can, it's $329. I have one in stock, we are building more.
