turbosmart recirculation valves so these are really popular kind of
cheapish upgrade that people love to fit um a lot of time i think people don't really know what they
are what they do but they want one because it's turbo smart and they look cool um so we'll go
through what's in the box what it is and uh how it works so in the box you will get the valve itself
which is black anodized fancy thing um then you also get um new mounting hardware
and a banjo now these banjos are known to leak a bit and they do on the wastegates
so now they actually supply the banjo and a straight nipple which is what this has got
installed on it so i wouldn't really recommend installing this banjo unless you have to because
they're not the best to be honest um you also get sticker and then the instructions so you just uh
go to the link i don't know why they're not using a qr code yet seems a bit old-school
but yeah link with the instructions on how to fit but it is like general instructions
so the valve itself like i say black anodized they look pretty cool they're nice
um they definitely aren't nicer than the forged ones um i don't know why that is i think maybe
i think the four drones tend to look a bit cheaper because they're not anodised they're just kind
of raw machined and that tends to sometimes make aluminium parts look a little bit cheap
so you've got the piston inside which has got a it's a just got an o-ring kind of trapped in
the end of it and a spring i'll disassemble it in a minute but i'm just kind of showing how it
works so we've got an o-ring on the outside which is what seals against the turbo an o-ring on the
inside which which seals against the compressor housing on the inside and then that piston so
when the throttle body closes the vacuum opens up
boost pressure pushes against this piston and then is allowed to flow out of these holes
kind of through and out into the uh turbo inlet basically so it's really simple how they work how
these differ from the oe style is that there's no kind of um rubbery diaphragm these have got like a
like a sealed piston and spring which makes they're not maintenance free but it does mean that
you can kind of maintain them so with the oe one realistically there's nothing you can do in terms
of maintenance they just last until the diaphragm wears out and and kind of tears and then that's it
you can put a new diaphragm in them but you know again nobody really does that they just tend to
fit one of these turbo smart or forge type valves so that is the beat of these is you can
maintain them so if i open this up i can show you what's inside they are quite tight to get going
but once you get it open it's because there's a again another o-ring in there so
again the beauty of all these o-rings is everything's nice and serviceable
you can change earrings if you need so that's the standard spring that comes with them
and then you've got this piston which is again it's quite nicely machined um
it's a i'm not actually sure what the material is it's either coated or it's brass i'd imagine
it's brass because there's less friction um and it'll be cheaper than coating it but i don't
actually know and then the end of the piston is definitely steel and it's uh fastened in with uh
a um like a thread so it it threads in from the inside then you can tighten the kind of end um
i don't i'd imagine it's steel because they want the weight so that the brass makes it um you know
you can get a nice tolerance and it'll slide in and out nicely because brass is a nice uh
material for that but you want a bit of weight and that's why they've got that steel uh end on
that piston because that'll kind of have a nice spring action then they'll probably need a less
um stiff spring to get it to action nicely but like i say everything's kind of oiled and nice and
serviceable which is cool and again there's that rubber o-ring which seals against the inside so
you can see there it's pretty simple there's not many components but it is all nicely put together
locating tab for the spring and then you just thread it in so i'll show you now how it goes into
the turbo and then how it works when it's inside there managed to find my 10 mil as everybody knows
they tend to go missing um and it's literally just these three bolts so we've got an efr
turbo to show you on but basically how these recirculation valves this type that fits
basically all the modern voxels basically all the modern fords and quite a lot of other stuff
um i mean we tend to sell them mostly for voxels and fords but yeah they fit quite
a lot of cars that specific valve because it's basically it's a bog warning design and
obviously board want to make a lot of oe turbos so this is a direct fit for an efr as well as
you know of course vxr or fiesta st the fiesta st has some extra bits in the box though
so again these are quite tight because they're thread locked in so there we go you can see now
that's the cap spring very similar to the turbosmart one and then we've got this kind
of rubberized piston and diaphragm so this is this is how these are different this is like
a diaphragm and then after so many actuations the rubber basically dries out cracks and then
tears and then you get a boost leak and that sits in there so throttle body closes up
the boost pressure needs somewhere to go so this this piston opens up allows the boost pressure to
come back out or kind of reverse down the boost pressure track from the intercooler
out of this hole because the uh the valves opened up boost pressure forces this valve open and then
it can come into this chamber and then out of this slot back into the compressor wheel
and compressor housing and then it'll it'll usually either spin the compressor wheel some
more or go back out the air filter usually it's spinning the compressor wheel some more
and it's just kind of recirculating um and that's what this kind of valve is
so the turbosmart one it literally is just three bolts so you take out the standard one
with the diaphragm and the spring and this will be the same for like a course of xr or fiesta st
this is pretty much what they all look like inside and this one just bolts on the only
thing you have to be you have to be aware of is that this in this turbosmart one there's two slots
and that's where the air will come back out of the boost pressed boost pressure air will come
back out of and you want to make sure that that is pointing towards this slot so i've
got my two slots here and when i put that in i want that that way it would still work if it was
the other way around but it wouldn't work as well so you do want to make sure that those two slots
are pointing towards the exit into the compressor cover because it needs to go in there like that so
these are a thing that i say a lot of people tend to buy um it's not going to make any more power
not really going to aid reliability because the car doesn't tend to kind of stop working when the
diaphragm fails but it is a kind of long-term reliability thing so if you fit one of these
you know it you know that you're never going to have this problem but it is worth bearing in mind
there is a little bit of maintenance involved with these they will pick up a little bit of
dirt and crap obviously the air that comes in is filtered but it's inevitable they do pick up uh
you know dirt particles and because it's oiled you know it tends to form a bit of a
grinding paste and yeah i guess it's one of those every time you service the car
10 000 miles or so you're going to want to take this out tear it down and give it a clean up so
