This is a good catch can but pretty dangerous by adding unmetered air from the ventury intake. It is after MAF and could cause lean mixture. Increase mpg but also temperature in the combustion. Watch your head gasket .

@@rondhole This is far more than a catchcan. How is there unmetered air entering? Both the clean/fresh side that gets the air from post MAF and the Venturi, which provides the secondary vacuum source is also post MAF. And it retains an emissions compliant closed system. The average "catchcan" only traps from 15-20% of what passes through where this traps 90-95%. No other design comes close. We have 2 patents on it.

@@tracylewisperformance1328 I do not think the additional drilling original hose for the Venturi is necessary. It only adds additional vacuum but the concept of PCV is a positive crank valve, so it is more about pressure build-up in crankcase as the main source of flow, not the vacuum from the intake. The rest of the design is great. I just do not like adding an additional hose and destroying OEM intake. MPG increase does not happen, but a cleaner intake manifold and valves are expected. The way we drive makes a lot more different than anything else. Or get a hybrid with Atkinson cycles like Toyota 2AR and 2ZR engines with 40-41% thermal efficiency. From the time being, I will sell any KIA/Hyundai in anyone Asset, it is liability that can kill someone. The engines often like a mine or wild bomb, suddenly burn. Sell it and get a HSD hybrid definitely safe more fuel and money. This Catch Can fit Corolla hybrid or CT200h that has a problem with oil in the intake manifold. People can always patent something, but it does not mean anything without any enforcement. Especially, most catch can are Chinese products, they do not respect the USA or international law regarding patents.

You bet!

First and foremost I will say #1, just take a minute to remove the intake tube when drilling to avoid rubber shaving ingestion. #2, everyone needs to know to NOT use silicone spray lube when installing the hoses to make them easier to install. Silicone spray will destroy the O2 and AFR sensors if it's used on intake air, crankcase, or fuel components. The man was using his spit or breath to put water on the hose which is acceptable. My comment is mainly for this though (and it's long): I don't like the oil cap modification for 2 reasons. First, the inner diameter of the new oil cap separator device is visibly much smaller than the original fresh make-up air supply which is 1/2". That will restrict the volume of fresh air entering the engine, and that supply was designed to be 1/2" for a reason. With this setup, you are adding seemingly more vacuum to the PCV side with less make-up air volume to replace it. Illogical. The throttle body vac port will produce almost all of the vac at idle with the venturi port making much less. However, at part throttle such as cruising, there is still a very respectable amount vacuum in the intake manifold and you're now adding the vacuum volume of the new venturi port to it. If anything, you would want to upsize that make-up air system to 5/8" or 3/4" to provide more volume. The crankcase shouldn't be under a large amount of pressure or vacuum. It should be under a very very small amount of vacuum to ensure the blowby is removed and condensation is dried up by constant fresh air flowing down and throughout the engine. Second reason...why do you need a separator device at all on the fresh air supply? That line is nothing more than filtered atmosphere entering the engine from directly behind the air filter. There's no oil or anything in that air. Ideally, it should contain nothing. A hot separator mounted on the engine will not condense atmospheric humidity, and the H2O of combustion blowby is constantly pumped out by the PCV system itself. 🤷🏻‍♂️ It is an unnecessary addition which restricts the flow volume of fresh air. The only thing that restricting make-up air volume will accomplish, is allowing the crankcase to be pumped down to a deeper vacuum. That doesn't really accomplish much, and too much vacuum will actually damage gaskets, damage seals, and draw contaminants into the engine through any crankcase compartment (includes T-cover and valve covers) leaks which may be present. Not good. Perhaps the restriction of make-up air and subsequent increase in crankcase pressure is to create the illusion a dramatic assist by the venturi device? 🤔 I can't say for sure, only speculating. The difference between the rated EPA mixed average of 23mpg versus Joey's actual of 27.4mpg is explainable by several factors. First off though, was the chart of data verified by measuring the gasoline volume burned at the end of the testing? The instrument cluster's fuel efficiency result is often incorrect and inflated by 1-3mpg on most cars. My own is high by 2 mpg nearly every time. The only true way to calculate actual achieved mpg is to find a gas station that you like which has a nicely flat and level spot at any pump available, fill the tank fully until the pump cuts itself off, drive until the tank is down to 1/4 or 1/8th full, and then return to that same gas station and that same exact pump and refill the tank fully until it cuts off just like the first time, making sure the nozzle is positioned at the same exact depth as last time (just fully insert it to the hard stop and it will be repeatable every time). THAT will give you the actual, true mpg of the mixed driving that Joey did. Divide the miles driven by the gallons of gas pumped into the tank. Use the temporary trip B odometer to keep track of exactly how far you've driven between the fill ups for the calculation. I will posit that if Joey used the instrument cluster's data rather than properly calculating mpg this way, the data is inflated by 1-3mpg. Furthermore, the observed difference of 4.4mpg can be explained purely by the driver's behavior. If I am careful to drive gently and efficiently, I can squeeze several more miles per gallon compared to when I'm having a bad week and I'm late to work racing around and loading the engine much more. 🤷🏻‍♂️ If Joey was told beforehand that these mods would possibly improve fuel efficiency, that is a totally guaranteed diagnostic suspicion bias due to an unblinded subject and it makes the data less reliable. You could like have plugged a dummy OBDII device into Joey's Telluride and told him it would boost his fuel efficiency, and he would subconsciously drive more gently from then on giving a similar 3-4mpg increase even if he didn't intend to do so. Add tires into the mix too. Are the tires properly inflated and the same brand/model as the stock tires with which Kia recorded the EPA estimate? If Kia used a softer wear grade B tire and Joey has harder AA grade tires installed which are a few PSI above spec, that will return a similar efficiency increase due to the rolling resistance change. These small seemingly unnoticeable changes can make a big impact on overall fuel efficiency. To support that statement I will say what I experienced with my Corolla when I drained out the WS transmission fluid and replaced it with Valvoline MaxLife ATF. The older models of that transmission used T-IV fluid, and Toyota switched to WS in an effort to increase fuel efficiency. WS is a lower viscosity ATF, like DexVI and others. The MaxLife is blended more closely to the previous T-IV's viscosity. After I did a complete cooler line fluid exchange and filled the AT fully with MaxLife, I took a 2 mpg loss instantly due to the increased parasitic pumping losses of the thicker fluid. I had recorded months of WS economy with Fuelly prior to the fluid change, and I have collected years of data since then. It was a demonstrable drop, averaged over a very long time which made driving style changes trip to trip a non-factor. Tire pressure changes from a few psi low to a few psi over spec can make a remarkably noticeable change to tank averaged mpg. TL;DR I like the design of the catch can baffles; it's undeniably superior to the others. I see the fresh air separator as unnecessary and potential negative. I think this experiment may be fundamentally flawed in a few different ways and I'd suggest making a second video with a better experiment using many more rigidly controlled variables. Install one of these on your wife's car or another friend's car without their knowledge and without telling them that it may affect their fuel efficiency in any way. Check and adjust their tire pressure throughout the test, and instruct them on how to collect their data on fuel usage and mileage driven as I described above. To make it easy, maybe even set them up with a Fuelly account and the app. They MUST go to the same exact gas pump and put the nozzle in the same depth and allow it to auto stop by itself one time; no top offs. If you observe a 4.4 mpg increase even when these variables and methods are corrected and the subject is blinded successfully, I will accept the result fully and happily and accept that my hypotheses and speculations were incorrect and the product is worth purchasing. Truthfully though, it's worth purchasing if one drives a GDI car anyway, cuz intake valve coking. I'd probably just plug off the second output port and omit the venturi device, and I'd CERTAINLY skip the make-up air device.

PCV doesn't route exhaust to the intake, that's the PCV's job. The small amount of exhaust that gets passed the rings will go to the intake, but no catch can is going to change that, even this fancy one. Comparing one's achieved mileage to the EPA estimated mileage is useless in determining that this device is helping, you need your achieved MPG before and after installing it. I can't imagine how cleaning the PCV air increases MPG, I'd love to see actual evidence. Tracy's statement about 'normal' catch cans being no more than 15-20% effective is complete BS.

Excuse my ignorance but, how making a vaccum in the crankcase increase efficiency of the engine??? If one piston is sucking air or after explotion of course make sense, but when piston goes up??? It does not help in compression or exhaust phases, explain that!!! Thanks

Several ways. When pressure is allowed to build in the crankcase the piston fights this on each downstroke. Suction aids them. SO some parasitic loss occurs. Has no effect on the compression stroke. The most benefit is retaining piston ring stability and improving the seal VS pressure present in the crankcase causes "ring Flutter". A condition where the rings enter into a state of rapid vibration. Low tension piston rings are used in all engines today so this is even more critical, and then we have the elimination of knock retard caused by oil ingestion.

This video is a good example of how maintaining vacuum suction results in better ring seal and more power. The first pull is venting to the atmosphere. The second pull is pulling vacuum suction. These are the versions we use on ALL of our race engines: kzread.info/dash/bejne/X2uWqdWhmdWre6w.html

Comparing OEM fuel efficiency estimates to uncontrolled, random drive cycles is not even remotely credible. There is dozen factors that affect fuel efficiency on any given day, none from what was shown were held constant. I miniscule change in crankcase vacuum will have no measureable affect on efficiency. If you install a dry sump system and run 10 inHg in the crankcase using a vaccuum pump, power and efficiency increase can be realized in high HP engines, but 17% increase in these minor change is misleading. What was the average crankcase pressure before and after, over a wide operating range did you find when you tested? Any improvement in flow, ventilation, will certainly help to keep the engine cleaner, especially GDI engines.

@tracylewisperformance2270

Todays engines are all built with low tension piston rings. And these require suction below and pressure above to hold them stable and have maximum sealing. When crankcase pressure is present, this lifts the ring off the land an a condition known as "Piston Ring Flutter" occurs where the rings enter a state of rapid vibration and blow-by increases resulting in less power made and a less efficient burn. We have decades of Divisional, National, and World Championships in multiple classes NHRA & IHRA and designed this system to emulate the vacuum pump systems we have used for decades in the racing industry giving the same benefits, just not as robust as a belt driven pump system. If you measure the Venturi at 4500 RPM you will see from 7-14" of vacuum produced. The special check valves always automatically default to use the strongest vacuum present at any level of operation. The closed system allows NO unmetered air in and does not vent to the atmosphere. So we take the average crankcase pressure during acceleration and WOT to a negative. If proper vacuum suction is pulled gains are also realized by reduced parasitic power loss of the pistons fighting the crankcase pressure on each downstroke and aiding them with suction. This is the ONLY Patented true full time vacuum based crankcase evacuation system. If there is any doubt on how and how well the system works, we will gladly buy back any system bought to test the actual results. If you walk the pits at a National event you wont see ANY cars not running a vacuum system unless a specific class prohibits it or in the case of TA and TF, where most of the oil is pushed from the crankcase each run, then blow-down tubes are run into a large catch tank. But we guarantee these benefits or will buy the system back. We have yet to have any light fleet customer return a system. In fact we provide a system free if more that 100 vehicles are in the fleet and the fleet owner/manager tracks all fuel usage to see for themselves. No games. These fleet owners would not keep purchasing them for each new vehicle if they did not do as claimed and demonstrated here. Crankcase pressure is NEVER good in any way.

This system is under $500 and the testing as done here, and the dozens of other independent tests done by others that doubted the claims. There is NO device on the market that actually can guarantee at least 10% increase in fuel economy. The 17% average gain here is above normal, but 12-15% is common. As this provides full time evacuation on the crankcase oil stays clean 2-3 times as long and anyone is welcome to test it backed up by oil analysis. The way it gets the increased MPG is mainly from reducing or eliminating knock retard that causes the ECU to pull ignition timing allowing the engine to maintain optimum timing advance and to a smaller extent you only want air and fuel in the combustion chamber. Oil, water, acids, etc. all disrupt the burn and the amount of energy released so of course less power and fuel economy.
