I installed my Vibrant catch can about 2 months ago and have noticed a increase of MPG from 21.22 to 23.65. My mileage is tracked thru a app on my Hero so I didn't mess up the reading. I guess getting that hot air out of the intake lets the car do it's job a little easier. It's a nice plus to all the great things a catch can already does.

That borders on amazing and I wonder if it might be due to the fact that the heater fan is off in the milder spring weather. Your indicating about 10% increase, which I cant believe for the can. W dy

 

If it really did this, then why hasn't the government mandated the catch can use on all vehicles? My guess would be that it is does not improve mileage.

 

More likely the difference in seasonal additives in the gas you are using.

Here in Minnesota, there is at least a ten percent difference in mileage seasonally.

And oddly enough, even the warm states adjust additive mixture with the seasons.

 

You driving a SRT or a limited? I get 25-26 mpg on my 2005 limited,6 speed, no mater how I drive fast, slow aggressive, or wimpy. With the power and torque my little limited has, I am completly happy with that kind of milage.

 

I didn't see any change in mileage with my catch can. I've had "things" apart several times since adding the catch can and I see no sign of oil in the manifolds either.

that's a good thing right there....it would add to the efficiency of the motor....getting ready to start installing parts soon, just as soon as I get the manis modded....saving a few bucks up for that...should ship them out this week....now that should add some fuel mileage....lol

 

I just saw this thread after I made another one similar, darn. If no better reason to get a catch can than to keep the inside of the intake clean, look at the pics of my throttlebody in this thread

you guys running on coal water up there? LOL....get that thing a catch can.....Rob has'em....

 

94 octane is all I put in up here!

 

That's the TVT catch can right? I've been thinking about getting this. How do you like it?

 

Hey, I didn't believe it either. It could be the change in additives but thats a large change. I'm just posting what i see. And yes it is the TVT CC, great product. you can cut it to any size, mount it any way and it has WAY more then enough places for plumbing. really a clean can.

and I'm driving a 07 base...

 

My Milage has increased two to three miles to gallon on my Base roaster not doinging anything but driving with the top down every chance I get My money goes with the attivates it is a 2005 with 14000 miles.

Kurts could most likely answer this better than I but the additives for winter fuel are most likely ethanol. Ethonal has 1/2 the BTU energy per gallon of gasoline. Something they didn't tell you when your legislature passed all them ethanol mandate laws.


Nuf said.



Now, I missed it, what is the purpose of the catch can? How does that possibly improve milage?

I routinely get 23 to the gallon with a mix of city/highway driving so I don't think that kind of mileage is special anyhow.

 

I'm sure the catch can helps fuel economy, but only by a minuscule amount. I'd say your gains are due to seasonal/elevational differences.

But since we are on the subject... I've been wanting to get a catch can but I refuse to pay $180 for one. I found this how to:

Home Made Oil Catch Can Photo Gallery by AZ Solo at pbase.com

Looks neat, and the best thing about it is that the catch is clear so you can see the crud coming out. Looks like it'd cost about $40 and looks cool.

 

BrianBrave did a similar catch can to that.... and I copied it....then went to the NW can.....

 

I started with that coalescing filter and found it too restrictive, some had dip sticks backing out due to pressure build up. Just try to blow thru it.....................

At the least I suggest trashing the filter element ment for compressed air and using a piece of fiberglas to catch the oil mist, without the terrific back pressure it causes under high boost conditions when blow by is significant. Woody

Others had first played with that, I designed one using the cut off length of the first CAI pipes from Rob at needswings. With stainless steel wool, the passage of spent gasses is low restriction, drains well, and Rob even made a clean package of it.

 

I'm sure the needswings catch can is great, but it's $140 (not 180, sorry) and I really like the idea of having a clear container to see all the gunk so you know when to empty it.

I guess I'll have to do a search here and see what everyone else has done. Thanks for the heads up, woody!

EDIT: Looks like quite a few people went with this one: http://www.jegs.com/i/JEGS/555/52205/10002/-1?CT=999

Looks like that would fit my budget and has the clear catch so I can see it. I'd be interested to see some feedback for those who have this setup. Woody?

 

Again Again, that is one that I tested among others and it is too restrictive. Pull the filter if you will and add a fiberglass pad to replace it. You dont wanna try to breath or blow thru that filter, and when it gets oily, its MUCH WORSE.

Fiberglas mat for repair, a fist of airfilter fiberglas from a home filter, or another sponge material will be workable. Dont take it for granted, please question the church and suck or it used try to blow thru it to see what restriction your talking about.

The JEGS air filter is intended for water separation and such from an air compressor, thus the 150 PSI rating on the "globe". Please note the design and style of the combo air regulator and dryer assy for $15 bucks, sameo thinggy here: http://www.harborfreight.com/cpi/cta...emnumber=43242

THe JEGS 5 MICRON filter rating gives the deal away; a micron is one millionth of a meter which is 39.37" and therefore about 40 millionths of an inch. Thats small and there a terrific pressure drop in the intended application. Please redo the filter element, and do the search of the number of guys that were using this earlier on, with their posts that complained of issues.
