right so splitter got some soft wood ply this is not really what you want to use
you want to use marine ply because marine ply is uh i guess as it sounds far better
in kind of all-weather applications this software plug probably won't last that long but it's what i
could get and i want to keep cracking on with it because we can get it from across the road we'll
probably just use this as a pattern so this will be what we kind of work with to create
like the standard thing and then we use it as a pattern because these will be aware item really
so i've kind of cut the sheet in half pretty much and got it under the car just supported it on the
trolley jack for now i'm going to cut it down to size first i'm going to cut it to shape first and
then we're going to figure out how we're going to mount it after because i want the splitter
if possible to be totally mounted to like the chassis of the car and the bumper be separate
again so you can remove the bumper without having to have a heavy splitter attached to it
all the time because it will be quite heavy and plywood is quite heavy because it's quite dense
so yeah the first thing to do is to get it lined up under the car right the splitter will finish
basically exactly at the back at the front of the front wheel arches so where the wheel arch starts
that's where the splitter will finish and i think in the time attack regs
um for like pro front wheel drive because that's basically what the car will end up
in warren doesn't really care what category the car is in he's not going for trophies
he just wants to drive around and have fun which is the way you should do it
but there still is a regulation because if you go any bigger than that you then get into pro extreme
and that means you're on track the same time as you know full-on monster cars and that's not fun
because then you're getting out of the whale time so yeah we're going to keep it to 150 mil
150 mil extended from the body of the car obviously is already a wide track and the uh
wide track front bumper does hang out front of the car more as well so it will probably be quite big
but the easiest way to mark the shape of the front bumper like i said we just need to clip
it at the back get it get it in position and then we can just mark it round using like 150
mil off cut of something or other so we can mark it easy so quickest easiest way of doing this
is i need 150 ml out from the bumper i'm going to go slightly under that just in case you know
whatever's tape measure is wrong so i'm going to go 145. literally just got a piece of cardboard
with a sharpie attached to the end of it and then from the point of the sharpie to
the to the back of the cardboard i've got 145 mil and i'm literally just going to go around
the outside of the bumper keep the cardboard as straight as i can and that'll give me roughly
here or there 145 mil out from bumper so i'll start that side because it's easier
so got that marked out now again that's like the quickest cheapest easiest way of doing it it is
as accurate as it needs to be so i'll cut that around with the jigsaw put it back under the car
i'm probably just gonna screw it to the bumper for now just that out of the trolley jack in the way
and then we'll pretty much just construct a frame that will go behind the bumper that will probably
attach to the subframe that we that the splitter will then actually be permanently attached to
so got that cut out that's cut to shape what we need to do now is temporarily attach it to
the bumper so there are already some holes in the bumper where a splitter was before i think
never came to me with a splitter on it but i think one was on it
so i'm just going to mark those existing holes just so i'd have to make any more
holes in the bumper i'll mark those then i'll just put some um like nut and bolt it through
and then we can take the trolley jack away and hopefully it'll flatten out a
bit because obviously because i'm pressing it up in the middle it's it's bowing out
see i'll try the jack away and then we can start planning out how we're going to actually uh attach
it because it does need to be fairly solid it'll probably be some kind of steel framework maybe
some uh some thin flat steel or something like that but yeah that's the next thing to do now
right so i've got that bolted on now charlie jack's out the way
so what i can start to do is plan out how i'm going to do this kind of internal framework
i don't really want to weld anything to the subframe i want to try and bolt as many things
on as possible so i think what i'll end up doing is actually bolting it to the chassis legs um
i think there's a few reasons for doing that i want to again it's i don't want to
modify the subframe in case the subprime ever needs replacement i know the subframe
on this car is already modified like caster adjustments and it's also been strengthened but
i still don't really want to add anything to the subframe unless i absolutely must do
so yeah i think we'll probably try and drop something down from the inside to the chassis
legs maybe because we've still got some room there and then that's not going to interfere
with where we want to actually create some kind of mounts for the oil coolers
so yeah that's the next thing to start looking at really
so we're a bit further on from that now uh some time has passed
there was some complications with doing the split amounts um that i was talking about
and we we we're kind of on with it but i kind of got distracted by doing other things that
seemed a bit more important at the time given you know the kind of time was running out with
the car and the splitter was always going to be a splitter and four orientated things were
always kind of going to be an accessory they're not necessarily required to go out on track but
have made some progress with it most of it we didn't film because it was done kind of
after hours weekends whatever and that is this oil cooler and splitter mount on this side now
so this is kind of finished ish in that um it's all mounted like the oil cooler is
where it wants to be this is the engine side oil cooler so that's not going to move now
we can figure out doing the oil cooler lines we've gone for a slightly smaller line on this time
um the kit that was already on this car is a dash 10 which i think is a bit big i don't think
you really need that the reason i don't is that if you look at the actual oil pump outlet it actually
is a lot smaller than a dash 10 line so we're going to use dash 8. just makes rooting the
lines easier they're smaller lighter you know you don't need it the oil pump can uh you more the oil
pump will have a far easier time on a dash on a dash 8 line i think so that's what we've got the
oil cooler is mounted we've obviously got to get some kind of pipe work from here to here because
that's where the oil cooler will feed into um so there's quite a bit work involved in that still
and then kind of at the bottom this is kind of how the splitter will mount the splitter will
mount flat up to here with some bolts in it uh probably four bolts either side there may be a
couple of bolts in the middle so we'll basically build this same framework on the other side
and they'll probably be um kind of a a piece of box that will come across to the middle
and then across to the side as well and we'll try and brace that as much as we can
um the front of the splitter will probably be braced back to the inside of the scoop
given that again that's all quite solidly mounted so if you can imagine the splitters here
we'll probably have some braces that come up to the inside of the scoop or something like that
i'm not 100 sure yet but that's kind of where we're at with it
so it's more or less just a case of finishing off what we've done
that side that side now now i'm not bothered about getting it perfectly symmetrical because
no one's ever really gonna see it doesn't really matter and i had to fabricate most
of it on the car um well on the car and taking it off the car to tack it and weld it
because i don't have a portable aluminium welder so that's also
some of the reason why it was taking quite a while it's quite a slow process to do that
so yeah just a case of now probably going to pop the bumper back on
fabricate a bit more framework lay it in on top of the splitter brace it up towards
the body get it all mounted solidly and then we should be able to take the bumper off and leave
the splitter on the car that's kind of where we want to get to with it we need the splitter to
be totally independent of the bumper we mounted the splitter to the bumper kind of temporarily
but you don't really want again the bumper as i've said many times bumper doesn't really
fit very well it's not really very strong and you definitely don't want to kind of pull the
splitter to the bumper because it won't do anything it'll just be so flimsy that it
won't actually work so yeah that's that's thing to do now put bumper back on and start working
cutting some uh alley box and kind of tacking it and welding it together for the other side
so
so splitter is now mounted um not 100 yet we've still got bits to do it's really solid on the
outside which i'm really happy with because it's always hard to know exactly how strong it's going
to be until you've done it so what we've got you can see in a bit more detail now because the
gearbox oil cooler isn't mounted on this side yet we've got one post coming down
which is mounted on the inner wing and then one strengthener onto this kind of triangle section
and then a bolt in each corner of that and that is really pretty solid really i can you know i
can move the whole car just by the just by the wood um you do want to get these pretty much
mounted as strong as you can but obviously we also don't want to make it super heavy i think
i think we'll end up putting a brace straight between these as well so we'll
probably have just a piece of box that goes straight between these brackets
just to add a bit in the middle um not that i think we'll need it there i think and again
mainly the strength just kind of wants to be on the outside where it's going to catch most of the
you know the air really um and then it'll be trial and error from there i think it'll be a case of um
seeing how it goes on track kind of watching it really and seeing how much it flexes
but we'll definitely need to brace it right in the middle so furthest away from these outside points
that's where it's you know as you would expect the weakest so what we're going to do is because this
is pretty solid the the front scoop as the bumper sits on obviously all this area is open so we've
got some um little tie rod ends and we're just going to create a little bracket top and bottom
well this one will just be a hole straight through the side we'll probably weld a bit of a
strengthener on the back to double it up thickness wise again don't want to go ott but we can make
it quite a bit stronger without adding loads of weight it'll just be a bolt straight through there
and then we'll just add a bracket onto the bottom here that'll carry that and we'll do that both
sides and that should then you know then it will be pulling down on this again which is all very
solidly mounted so yeah we're getting there with this um there's still going to be some finishing
touches to do to this splitter again i'm not sure if we'll keep it in this material um i would like
to use a slightly different grade of ply like i think i already mentioned in that older footage
but we're at a point now where we're probably running out of time
so it'll it'll do for now it'll definitely work it's just probably not going to last
as long as we would want it to last in terms of you know it's like 20 quid worth of plywood
you know how you know how long do you want that to last will it well last the season
i don't know it depends you know curbs weather stuff like that um it getting wet all the time
so yeah we're going to mount the tie bars on the front here
and then we've now got to mount the gearbox oil cooler this side just like we did with the
engine oil cooler on the other side the other thing we can see now is how we're
going to pipe the air to the gearbox or call us if we look on the other side you can see
what we've got is the air inlet for the coolers coming in here and obviously it's it's at the same
angle as the bumper and these are pointing down so we've got a fair way to go but given this is all
fixed and as the bumper comes on and off we should be able to make it work quite easily i think
we're probably just gonna end up solid piping it i know i originally said about having it um
in like the flexible convolute type rubber silicon tubing stuff like the reinforced type stuff which
you often see the problem is it doesn't tend to last i don't think i think once you start
to cut it it tends to unspiral on its own so i think what we'll do is we'll probably just
use an aluminium bend the brake duct comes in around here
so with the bumper back on we'll have a look at um where a bend can go but yeah we'll probably use
some aluminium bends and come up and round like that or over and round whatever works really but
yeah there's still a little bit more to do on this front end but it's definitely getting there now
so i've got these tie bars all sorted now i had to make some little brackets
i might um put a little bit of a radius on there yet just so that it uh you know isn't so sharp
and at the minute i've still got my bolts kind of going in from the underneath
um i'll put some t-nuts in there so that it's basically just a thread it's like a it's like a
thread with uh some spikes on it so as you tighten the bolt down it pulls the nuts into the wood
um does that mean that the bottom of the split is completely flush then i know some people um
kind of have the have like these on cables so that if you hit the splitter on the curb or
whatever it just kind of pushes the cables up but given how it's quite solidly mounted at the back
i think these are bendy enough that hopefully if it hits any kerbs it maybe only just damages
a splitter rather than damaging all the mounts i don't know um depends on how hard oran drives
it i guess so there's still some bits to do we want to put a nice radius on the front of this
the whole idea of the splitter is it's splitting the air so i think technically you want like a
three-quarter of a radius on the top and then quarter of the radius on the bottom
just smooth it over nice just so that you know as the air hits it it's kind of passing over the car
and then under the car we've also got the gearbox oil cooler mounted on this side now so
we can start looking at where the pump's going to go and plumbing it all up
and as well as getting the air from here to there um so yeah we can uh start working on
a few more bits now but yeah we'll leave that for next time so thanks for watching
