After
the 1st round of Time Attack at Oulton Park I've decided to install a
smaller rear housing on the GT42 turbo I'm currently using. Oulton
being a bit more technical than some of the other circuits showed up
some lag on a couple of the corners. I've changed it from a 1.15 to
1.01 AR so hopefully that'll make it a bit more responsive for
Knockhill this weekend. If not I might drop down to a GT4094, not sure
yet. Also, I've off to Nitron Racing Shocks tomorrow to get the car
corner weighted, it'll also give me the new weight of the car after the
weight savings I've been performing on it, I'm hoping to have knocked
off 50kg with the doors and boodlid. Unfortunately I've added some
weight with the weld in cage and triple box exhaust, soon see tomorrow.
28/04/09
Well a
bit of an update on the car, managed to get it all finished off
Thursday afternoon, just in time for Time Attack. The car itself worked
a treat for the full 2 days with no issues. The AP Racing brakes are
the best I've ever experienced, enormous stopping power time and time
again.
The
handling is a huge improvement on last year, I now have the confidence
to push it in the faster corners with a really nice neutral balance to
it. I still want to rose joint the suspension arms at some point
though, (its never finished!) Definately noticed a difference in grip
levels now I have the APR rear spoiler fitted. I didn't really get to
play around with Nitron dampers as I was to busy learning the track.
The
Racepak IQ3 dash is a marvel, for anyone doing plenty of track days it
is a must, so easy to read everything along with lap timing, its
perfect in every way. The fuel swirl pot worked a treat to, meant I
would run very low on fuel with no fuel starvation problems.
You can see a report from the Time Attack weekend here, I think we did quite well! Check it out here
21/04/09
Took
the car for its first drive tonight, my god, I've forgotten how fast it
is! Its so weird driving it without the wastegate scream, I can just
hear a distant whine from the turbo. Gearbox/flywheel noises dominate
now which aren't the best noises! Time to get that sequential box in
there me thinks.
20/04/09
Finally
got my AP's on. Had a nightmare with the supplier making them
correctly, I wont go into it all as it'll piss me off again! But
anyway, they are all on and look the business. The kit consists of AP
Pro 5000+ 6 pot race calipers with 362mm floating discs on the front
and 4 pot 335mm on the rear, Porterfield R4 race pads front and rear
along with Goodridge braided lines. I'll be adding these to my website
very soon, if you want to buy the ultimate brake kit for the Supra then
this is it. The kit will also be available with the road spec calipers
to if so required.
OK,
managed to get the fuel system in yesterday/today, thanks to Dazza as
he did most of it! Consists of swirl pot and 2 extra pumps to feed the
engine along with the 2 pumps I had in my fuel tank already. Nice pumps
these Walbro externals, very quiet unlike Bosch 044's! Shouldn't have
any problems with fuel starvation now.

09/04/09
And I
test fitted the fibreglass doors, fitted perfect, I'll be adding these
to my website ASAP. There so light compared to stock!

09/04/09
Finished
off relocating battery & alluminium washer tank from the boot to
the back seat area. Not a 5 minute job as the wiring all had to be
redone, also wired in another relay for the extra fuel pumps I'll be
running when the swirl pot goes in tomorrow(hopefully)

And
got my APR GTC300 carbon rear wing all mounted. I've used Max Racing
boot mounts as I prefer the look of them, the rest is APR. I've also
used shorter pedestals than what comes with the Supra kit to lower the
spoiler down a bit. Lets hope it works.
08/04/09
Ok,
the all in one catch tank & power steering tank is now in place.
The rear part of it is the breather tank, all baffled and gated inside
and the front part is the power steering tank, again gated &
baffled inside. Catch tank has 3 -12 breathers going into it and
breathes through the K&N filter on the side of it.
02/04/09
OK,
bit of an update, been working flat out trying to get my dash finished
off, finally got the carbon all cut out and the Racepak, AFR gauge,
boost controoler, Racelogic all wired up and fitted into the car. I'm
pretty happy with the way its turned out for my first attempt at a
carbon dash.
Also finished off remounting the boost controller solenoid.
30/03/09
Got my
Nitron dampers fitted on Friday. I forgot take pics of the dampers on
the car, I'll do that next time I have the wheels off.
When I
had the dampers made I wanted to have the canisters mounted under the
bonnet and in the boot area, I know from our RX7 and Steve/Ben's cars
that having the canisters under the car makes it a right pain to adjust
everything. Front was easy enough to do as the canisters can be fed
through but the rears required cutting a hole in the boot floor. I had
the Nitrons made with a suitable rubber grommet attached to the hose to
seal the hole up again once fitted, you can see that in the pics next
to the canisters. I'm very happy with the final result, lets hope they
work well now!
Passenger side front mounted canister, nice and easy to adjust if needed

Drivers
side front mounted, also removed abs/traction control relay box which
frees up some room, and I've relocated the boost controller
solenoid(not pictured)
Boot
mounted canisters. Still got to remount battery and windscreen washer
tank to the back seat area, its on the big list of things to do!

Next
job which I haven't been looking forward to is making the dash for the
Racepak IQ3. I'll be keeping the stock dash pieces in place for the
moment covered in sheet carbon, takes bloody ages to cut it all out and
make it look nice! I've done these 2 bits so far, next is the centre
part where the Racepak will attach to, I'll hopefully get that finished
today with any luck.

My new
catch tank/power steering tank arrived yesterday, looks the business
this does, its going to mount where the abs unit used to be, 2 units
built into 1. I'll post some pics up when its fitted

11/03/09
Bit of
news, my Nitron 3 way dampers turned up Monday, these are proper
quality, best I've ever seen, lets hope they work as well as they look!
They'll also be available in 1 way & 2 way as well. I'll get them
on my website ASAP.
I've
had the cannisters made with enough piping so they dont have to be
mounted under the car. The rears are going in the boot and the fronts
are going in the engine bay, makes life easier adjusting them.

Fibreglass
doors arrived the other day, check these out, they weigh 6kg each, I
weighed a stock door without the glass and window mechanism in them and
they weighed 20kg. Should be on for a good 35kg weight saving with
perspex glass, I'm going to keep the electric windows though as it
doesn't weigh that much. I'll be selling these for about £800 + VAT,
just got to test fit them to make sure there a good fit.

Also picture of the Racepak IQ3 in its box, nice bit of kit this

24/02/09
A
couple of updates, wont be anymore for a couple of weeks as the car is
having the roll cage made and then off to have the exhaust made a tad
quieter. Anyway, I removed the ABS unit from under the engine bay, as
you can see it leaves a nice big space for other bits and bobs. I'm
going to have my catch tank and power steering tank in this area now,
along with the HKS DLi and Aeromotive FPR. The resistor pack was
mounted here before, I'll be rewiring that into the inner wing so its
hidden out of the way. Also fitted a new master cylinder just as a
matter of course. You'll see braided lines going to the master
cylinder, one connects up with the Tilton bias valve on the rear brakes
and the other end into a t-piece for the front brakes.

19/02/09
Ok, been doing more interior stripping the last few days:
The mission was to remove the dash so its loose as its going off to have the weld in cage tomorrow. Dash removed

What a
mess of wires, its had 2 alarms and a tracker over the years so there's
crap everywhere, will have to sort this when I get it back in a couple
of weeks

Pic of the back of the dash with the loom attached to it

The loom

I
removed the loom from the back of the dash and attached it to the car
instead, makes it easier to get the dash in and out in the future.

Tilton bias valve fitted in place on the transmission tunnel.

11/02/09
Fuel
swirl pot arrived today, I've made it to fit above the diff under the
floor, dont have to worry about boxing it all up in the boot area then
to comply with MSA rules/regs. Hopefully my measurements were correct!
Going to be running 2 Walbro's in tank which are already there and then
another 2 Walbro external pumps under the floor next to the swirl pot,
I'll post more pics up when we get cracking fitting it.

08/02/09
And the interior is now stripped ready, getting it ready for the weld in cage
08/02/09
Right been busy doing some ducting work. Brake ducts
now moulded into the front bumper along with a hole in the centre of
bumper to let a bit more air into the intercooler, this now meshed, not
shown in the pics.

Also, been working on ducting the oil coolers
Before shot, air just following its own path where ever it wants to go

Afternoon
of cutting sheet alluminium up, taking bumper on and off god knows how
many times and its done. Still want to box the drivers side one in a
bit better though. Hopefully it'll make a difference.

29/01/09
Getting cracking on sorting out the airflow in
through the front bumper. Going to be ducting the oil coolers into the
bumper properly so no air can escape around them, hopefully increasing
there efficiency. Today I concentrated on the brake ducting, the holes
are cut ready to install the brake ducts, dropped it off to the
bodyshop today to have it the moulded into the bumper and painted.

Steve Linton and I have just ordered our Racepak IQ3
dashes, these really are the nuts having used one in the RX7 last year,
highly recommend them. Cant wait to get it fitted in our cars, it'll be
a great tool for us as drivers to as we'll be able to overlay
information on braking points, corner speed, etc. from each car so it
should tell who's being a pussy! Does everything required, lap timing,
datalogs anything you input into it, I'll copy and paste from website
all the info below:
The IQ3 dash represents an entirely new concept in data logging dashes.
By placing the 32 channel data logger, 512 MB memory card, GPS board
and 3 axis G meter inside the dash, every feature of the data system is
now located in one central location.
And, when that 32 channel data logger is one of Racepak’s exclusive
smart sensor type, that means that only one small cable will transmit
the data from all the sensors to the rear of the dash.
So, for the customer, this means:
No external data logger necessary No bulky, heavy sensor wiring harness
No beacon transmitter or receiver necessary for lap time data
No wheel speed sensor necessary. GPS provides speed and track mapping
The IQ3 data logger dash is designed to be a complete data center.
Contained inside the fully programmable dash is a 32 channel data
logger, 512 MB memory card, GPS board and 3 axis G meter. The
programmable shift lights are protected from sunlight by a molded
shield above the lights, while the low glare LCD display is well
recessed in the housing in order to provide viewing in all light
conditions.
The rear of the dash contains the connectors for the external GPS
antenna, Vnet sensor cable and the Power / Ground / Engine RPM /
External Programming Button harness. All sensors transmit their data
through a single cable (Vnet) which is routed to the rear of the dash.
This eliminates the need for a sensor harness, greatly reducing
installation time, complexity and overall weight.
All data is stored in a 512 MB MicroSD memory card, located in the
front of the dash between the programmable shift lights. This design
insures easy access to the memory card for data download.
26/01/09
Quick update, I ordered my new brakes today. After
working it all out with AP Racing I'll be going for a custom made setup
using AP Racing Pro 5000+ calipers 6 pot with 362mm floating discs on
the front and 4 pot 330mm on rear. Here's some pics of the setup we had
made for the RX7 last year which is more or less exactly the same.
