What is Time Attack Warren? I'll let you answer that one?
I've made it.
Look as if I were going to write a definition of time but the fact is
I can't. It's not racing is time attack, right, so several classes of different levels
of car modification, who can set the fastest lap time is a reasonable your
again the whole point of the smaller turbo
the g25 550 for a call now you can tip it in on the throttle and instant
power their story we got the real.
Ok, so we've got Warren from WG Motorworks
wide body Astra in for some some modifications quite a lot of
modifications for time attack this year is going to be racing this not sure
what category yet, because we might be flat floor which are limited to
certain categories, but we're going to be in loads of work on this so
we've got lowing the engine turbo manifold and downpipe all the
cooling package going to be doing so some arrow type work.
Maybe some suspension modifications is already pretty heavily modified
but
Now that we are going with even more power you know we need even more control over
all those aspects new project brand new projects Astra H VXR wide body
time attack race car is the official term racecar racecar years ago we
bought it and sell it was white as a roll cage the Body Care I think
we have to fit the body get to it.
So it literally no suspension.
No engine and gearbox no interior so it's been built up from that the
suspension is taken care by some custom units for the Old Time attack
that's a time attack on it which was put the volume up, so it's got a
customer have been so it's all been trying related with integral
robots is awful adjust the rear games that you got a drop kit for the
rear beam angles are actually kept around stand in the world that you
brought up as always help with the Handling do things probably staying
with the wide track.
100mm wide track on the car custom-made custom alarms being completely
custom custom brake kit clear the lower arm eventually we got the
engine in the engine was actually in our Corsa D VXR Astra H engine in
left lying around to pop that in it.
Just had a freshen up setting the time again wasn't planned to go big
spec we ended up just stage 4 as you call it was always it was but the
idea was right get in the car to learn the car we go big power.
That's the biggest mistake of your mate.
Is there jumping all the mods on it and then never develop the car so
I don't know what's good and what's not I don't know what they put on
the car at work which is always like the first thing people say I need
more power want to build hammer tacker and must have completely.
Before you go trading hardware brakes suspension is different but when
it comes to power limit what you got then go through which is exactly
what we're doing.
So we're going to put a GT 550 on it yet, because you want a nice
responsive set up because exactly need reliable 400 plus.
That's it and
To be different to make it a bit of an interesting project rather than
just using a bolt on my fold.
We're going to put it on the side of the engine.
It will be gearbox as a sideman.
Just to make more difficult challenge.
Yeah, so side mounts traditionally there any of the crack in the way
that we've got so we've got a kind of get rid of tank brake lines fuel
lines of all that top hat if you want to bring the Dam pipe down the
back which is the best way to do because we did ASAP get on Corsa B
and brought the downpipe down the front indeed.
Now only cause of baby did that because it was literally no room for
downpipe down the back wasn't possible that weak shell front for that
size of Turbo really so we're doing it at the side your least you can
go for.
We got a bit more room at the front for cooling package show gearbox
oil cooler engine oil cooler probably a big one that was on it before
bigger thicker radiator taller thin intercooler.
all day and fittings
all vibrant HD box clamps gearbox oil cooler kit as if it were going
to fit on a normal Road car Justin's car.
It's not a cheap ticket to do because a good quality pump into the
hundreds a good quality oil cooler £100 plus all the fittings and
houses required for the wiring sensors for oil temperature as we need
some we need we need to see the manual on a gauge to turn it on at
certain thermostatic thermostatic.
So just one less thing to worry about as you drive in but the good
thing about.
Putting electric pump on if we can also have a manual override so we
can keep your circulating even want the engines off because I'm cool.
An extensive and expensive yet probably not the body to get it out
because lots of Grand touring car.
I don't like as rep touring car as has been dropped the engine so
don't know yet at least an inch well on the engine.
So because that will give us more turbo clearance with the machine
machine spices or we could just get away with some regular.
Stop button holes in probably.
Yeah, that's not that's not too bad that pretty easy and your son to
do some Ajax as well as well on this pretty cool plugs removed.
This is why the engine drop is also ideal because he passed away from
the engine coolant gallery.
G25 550 so when you come for a corner you can type it in on the
throttle as instant power.
There is no delay, and you can feed the power in that's that's the
main aim and a squad that will turbos a new ones it's done
back-to-back Lapse of northern Nevada and sometimes a little simpler
not pushing that extra light 10 to 20% for 50 vs.
500 year was given reliability so one of the first jobs to do on this
car before we can really do any of the other bits is to lower the
engine we doing that because of the gravity benefits so the lower the
engine is the lower the centre of gravity of the car the car will
handle better to corner faster and it's kind of a quick and easy
things you can do when you making this many end.
Modifications that many parts are going to be custom that low in the
engine doesn't really add that much work, so what we done to start
with a temporary measure so that we can make things up.
We've just got some some spaces from some 25 mil CDs tube and put them
in between the engine down the gearbox side and on the
cambelt side
so this car got fibre Technics engine mounts so that's actually made
putting those spaces and even easier.
So they just a temporary thing once we know exactly.
I want 100% we're going to go in 25ml Lower with checked all the
clearances will probably have some spaces machined from Billet
aluminium and then case of making new front and rear engine studies.
That's about as much as we can go before the gearbox starts to get
really tight to the subframe.
We work out the front and rear engine studies so the original studies
won't fit now the engines lower so essentially the studies.
You know nowhere near the lineup with the with the original brackets
now.
We could.
Cut and modify the subframe at the front that wouldn't be a problem it
just means that you know if the car has a front impact or if there's
ever any damage done to the front of the it's a lot easier for us to
re manufacturer.
Engine now than it is to remanufacture the subframe because three
manufacturers suffering we need the car here it would be it would
become more complicated to do it that way.
So what will it will make 2 engine series 1 will stay as a pattern and
then if we have a need to remanufacture it.
We then got a second the second one to copy from that we know it
straight and then we can also if the card is it for an impact where
the sofa and gets damaged as well.
We can just put a new standard front of my mum.
Wouldn't have to worry about the whole grain mustard.
Just keep it simple as possible so a new Mount is the way to go ok, so
this Mount is Gotham Barbara technically.
It's basically just going to swap straight in here, but this temporary
bolt animal habbit a spacer in here to take up that slack this will be
pressed inside another thicker walled tube.
And then we'll have a laser cut bracket to take off the two.
Gearbox bolts the same as the original bracket does and I'll just be
welded onto the outside of that pushing their the rear bracket.
We will do with using the original now.
I'm going to make a bracket the bolts on the back of the engine with
an adjustable tie rod so again any discrepancies between these two
mouth that we manufacture will be able to take out on that tie rod it
once we've decided that we can lower the engine and how much were
going to do it the next door is to figure out where we're going to put
the turbo so we can do a side mount kit that's quite a vague anyway at
the side really but again will try and get a turbo low where possible
we try to make the down pipe routing easy we need to make the entry
into the turbine inlet easy, so it's not just a case of pumpkin.
It where we like we need to try and figure out.
Where is the best place to put it in terms of turbine, exit turbine
entry.
Compressor inlet and compressor exit, we need to try and work out.
Where is gonna be best to suit all of the who's now probably some kind
of compromise, but you want to try and hit the turbo as possible as
well, so we're going to go over the back with the downpipe.
So just going to be a compromise there in that we will have to remove
some more engine components to do that, but that is a lot more room in
front of the engine.
So we've got the beginning to the manifold tack together, so we'll put
that on now and show you ended up with the turbo.
Ok, so we've got a manifold with two primaries on it back together to
fix this to fix the turbo position that on.
This is where the beauty the v-band flanges comes in because we fix
this turbo position but if we were able to like a traditional 4 bolt
flange ansi 2500 84 would be stuck with that.
I just went in here.
So we can still adjust the turbo.
You know all down.
Obviously there is an optimal in terms of the core.
You want it as level as possible and that probably will end up with
it.
It does give us a little bit of scope for I'm going to go down to make
the entry into the compressor cover easy and the exit for the downpipe
that it's easier.
Just keep going to turbo relatively low in the engine bay.
Obviously is higher than where the original turbo that came off would
be and it is higher than one of our traditional bottom Mount kits.
but we have got the engine a whole lot lower and having a turbo in
this position give us a lot more it gives us a lot more scope in terms
of cooling package at the front we can go for a big front mount
radiator with v mount intercooler at the bottom and then we can talk
to all that in we can do it all that are back on it again which is
perfect for cooling efficiency and we can also use it to a Down force
and low pressure another car.
Ok, so at the minute.
We've got one of our standard top hits on here.
Just mounted backwards and a top hat fits fine the boost pipes a
little bit tight but that doesn't matter because anyway so yeah, we'll
have a titanium boots and that will come into the intercooler exit
here so we're going to try and keep the intercooler entry and exit
both the top on a vertically mounted call to try and keep the boost
pipe too short as possible which will response obviously this response
is kiwi.
Want the boots back to short as possible on an air tech intercooler.
You would generally have quite a bit longer boost pipe both in terms
of getting to the turbo and getting out of the turbo.
We want to keep those as short as possible so that ski in the design
process.
