Good day everyone GarageKing here and we are going to
find out when you're installing a catch can or buying a kit or maybe just doing
mods on your vehicle if the Elite Engineering high flow
valves are worth it these are for 3/8" inside diameter pipe/hose, most
catch can kits just come with these regular sort of universal type valves
this is what they all come with just a one-way valve
and here's another one I found online this one here it's labeled as a high
flow valve so I want to check it so how are we going to check it we're
going to set up some instruments and I'm going to show you now the one thing I
found is if you shake these valves nothing happens and if you shake this
one you can hear it so there's a type of
check ball in inside of this valve where these ones probably just have rubber
flapper valves so what I'm going to do is I'm going to
apply flow similar to that which we would probably
see in a vehicle and then we're going to measure the
pressure drop across each valve
okay so if we look at what we're doing here with the air pressure
this obviously isn't going to work because if you can see the two gauges
are not reading the same so we can't do a
pressure drop this would have been the optimum test
but I have another plan just to use one gauge, this really sucks I really
wanted to use two and measure the pressure drop but
I can't do it, but what we can do is we can measure the back pressure with one
gauge all right so we have our air source
there and you can see we're just over 10 pounds which is fine and the
compressor is plenty big so it's not going to cut on
and what will happen is it'll just provide a constant air flow through the
regulator at just over 10 pounds and then what
i'll do is i'm not even going to touch the compressor
i'm just going to interchange the valves and then we can just see how much a
restriction the valves cause so let's do it all right so I may have
to do a voice overlay, we'll see how it all works out
depending on how noisy this is i don't know if you're gonna be able to hear me
or not so we'll see if I do a voice overlay
so we'll start with this valve first we have it in backwards so we can tell the
one way works perfectly because there's 10 pounds pressure or just slightly
over 10 pounds pressure and nothing is coming out so we know
this valve works so let's take it out spin it around and see how much back
pressure we have
and there you can see we're at 2 psi so it's providing a little bit of
back pressure, not a lot, but it is providing back
pressure so we got 2 psi so let's try the next one see what
happens
now first I put it in backwards just to see how well it'll work and if you can
hear
the one-way valve isn't even working properly on it because air is still
getting through so now let's see how much restriction
this valve causes
and we can see this valve is actually quite restrictive we're at four pounds
so this one is restricting a lot of the air flow that is coming through
so very restrictive valve actually I wouldn't even want this
one on my car so let's go to the elite all right and we're back up to 10 or
just over 10 and there is no airflow so we can tell the one way portion works
fine so let's flip it around and see what
happens for airflow
and now it's flipped around from airflow and you can see we're at one pound
so with one pound that's a little bit of a restriction
but really not a lot so it's twice as efficient
as this one because if you remember this one which comes with most of the kits
is 2 lbs so now with 2 lbs so this one is twice as restrictive as the
Elite one, so the Elite one is actually really really good
and then if we move back to this one
this one's kind of just an embarrassment that's way too restrictive
basically we had 10 pounds we're back to around 4.5 - 5 so this
is restricting 1/2 of our airflow so that's really unacceptable to to
restrict half of your airflow that's just
nuts so and this one was even labeled as a high flow valve when i found it so
just a terrible valve so let's go back again
you can see there you go we're still at 2 pounds
and we'll go to the Elite
and there you go we're at 1 pound so you can see the difference between the
valves 1 pound
2 pounds
and 4.5 pounds so quite a difference between these two valves
and this one I'm actually ashamed of it because
the one-way valve portion didn't even work properly
these ones the one-way valve did work properly but the Elite definitely
had a really good airflow so that was a really cool test, it was valid it showed
just how much the elite flowed compared to the
second best or I guess your your average one-way check valves these are the ones
that are really really popular and then this one was just an
embarrassment so the test was good i'm going to throw up a chart here because I
just want to mention something. Someone may say oh but our cars don't
see 10 pounds pressure so your test wasn't valid
we got to get that 10 pounds out of our head because it's not about
pressure it's about airflow and restriction
that's what it's about I could have just had easily if i would have had a vacuum
source but i don't. I could have hooked a vacuum source up
here and just had it suck this way and it would have went this way instead
of pressure going this way and the only difference would have been instead of
the needle being on this side the needle would have been on this side
that would have been the only difference but the valves would have still
performed just the same so it wouldn't make a difference, the test is
valid so anyway another thought that came to my mind is maybe that's why they
want to void warranty sometimes?? I don't know..... If you get a really bad valve
I mean it could screw up your system I guess your
airflow because you want to have as least restriction as possible so
for me I don't mind spending the extra money as long as I get something for it
and with the Elite you do, you get something for it so I don't mind
spending the money so that's it for my video this week
hopefully you guys enjoy :) Any questions comments concerns leave them below
GarageKing over and out, and I will see you on the next one :) Thanks everyone :)
