Gear selector deja vue
and some more 'deja'
Lathed a bushing, since I had to elongate the OEM shifter cable... the system is done some more pics next time
On to a hot potato... with cooling
This has been a point of debate over the last few weeks... months even. Where to put the rad.
History has told us that putting them in the nose either requires custom rads = don't have the funds for that and K's like a short cooling
Or a huge waste of space (by being in between the dampers) = want to use it for electrics etc
Pontoons = needs either custom or motorbike rads and require the build of a model+mold+product
So I preferred it in front of the engine sucking air from underneath ( apparently the new atom has such a set-up) = need a new fuel tank and the flow
underneath is probs not laminar so quite a huge duct would be sticking out underneath... and trial fits pointed out that there is little room for a
Exhaust ? I'm wrapping it and using the OEM heat shield...
Another solution would be scooby intercooler style, using the airbox to duct air to it... CFD made me nervous about the outflow of air between de rad
and the engine.
Even having the rads parallel to the car and ducting air in (Honda VTR style) was considered.
In the end I came to a compromise having the rad at shoulder height between the occupants, aided by air ducted by the air box.
This way there is good flow, room for fan+ducting, a short cooling circuit and no need for extra bodywork.
So, OEM rad mount rubbers in need of a home
Just put a sock'n'et
Polo rad mounting not readily compatible with those rubbers
And now it is
Upper mount, captive nut plate
Some pieces of angle grinded steel
Holed and bent (attempt 99999)

|Out with the selector for some final tweeking... titled: tweeking_9.5_finalversion_7... if you catch my drift |
Just to prove that many parts go through many many iterations off camera... here is a rad shroud i spent several hours on and than binned
Just realised I have not taken a pic of how the rad shroud ended up
This is how the selector ended up, it's light and stiff this way... and fits the seats.
Than hours of trial fitting the paddles to make m fit 'just so' ... so here is the bracket
As by magic... here is the master cilinder

a dirty deed, done dirt cheap
I've posted a question in 'donor parts'... any help greatly appreciated

|For simplicity I decided to use the rover master+slave clutch cylinder this called for a remake of the pedal box |
Stiffer, lighter and more elegant
So something came in the post today...
So I was ...wrapping to the beat...
Some brackets and a heat shield later I'm confident that this area (and thus the rad and fuel tank) will stay cool
Everybody had me doing the run around, as no OEM throttle cables are long enough. In the end I bought the correct length outer cable from the bicycle
repair shop who has the stuff on a 1000m spindle and bought some steel wire in the DIY shop.
I had always planned on running the cable like this and was very happy with the snazzy bracket for a while
Then it came to my attention that the travel of the rover throttle body is quite long and so the throw on the accelerator pedal was too much
(can't go higher to get less throw as it will stick out over the bodywork).
So I elongated and rotated the lever 90 degrees and came out to this compromise... a bit sad that it isn't snazzy and that the cable operation
now lives where I planned my electrics and shopping compartment...

|This week... |
I'm still investigating how to connect my master and slave clutch cylinders... I've posted the question in the donor parts section.
ATM the prefered solution is to get some 4 or 5mm flexible hydraulic tube (6mm fitting) and use jubilee clips... some hydraulics guy told me that
Then, the MK2 fuel tank is not going to fit the newest alterations.. so we'll need an mk3. Made a model this time because I want it the 3rd time
to be the charm.
A whole day of making a removable tray later...
Even with the hear shield, the exhaust wrap I feel it's to close for comfort. So a few versions later we have 42l of fuel capacity and 20mm of
clearance between the heat shield and tank. For that little extra something I have some space age non conductive stick-on pads, just for the closest
Currently debating which water tank to use from my years and years of collecting, along with where to put it.
This debate also includes whether or not to use the OEM airbox and how in conjunction with the air scoop.
Ariel has an interesting way of doing it... but it means a lot of fabricating an loss of plenum.
had the gf over (believe it or not) and decided to do something nice together, my man logic went: she enjoys sewing =so cloth = carbon is woven = it
must be a cloth = QED she will enjoy some lay-up...
...God, was I wrong
But it turned out nice ! And the Dash got an outing after years in the box.
And the last job today was to fabricate harness mounts and fit them

|Thanks scudderfish, means a lot to have some encouragement! |
I started with the airbox... this is the OEM rover airbox
Hack sawed it to bits...
So it fits here... so I'm going to use the air scoop (CFRP) just as a cover. A bit disappointing as I was hoping for E46 m3 CSL resonance
noises, but that probabaly would have been a cacophony. This way I can use the OEM paper air filter, which is cheap, cheerful and better than a
chinesium pod filter
So it's a bit of a bodge right now but I'll have to plastic weld or glue some bits too it... and the water drain
After a whole day of fitting, bending, grinding, drilling
Then, the water tank had to be placed at a point higher then the head/rad/... somewhere where it wouldn't intervene with the air flow coming
from the rad and somewhere where I could block the acces to the cap (100% sure otherwise someone would nick it for giggles)
A few attempts and generations of brackets later...
The end is nigh
So I found a solution to my clutch line problem, this is some thermoplastic hydraulic line... it should be able to cope with DOT4 and my only worry is
that it is only rated for 20bar of pressure. The up side is that by heating the line and the fitting I could just push it on.
But It came to me that the slave doesnt have a bleed nipple ????!!!! How do they do that ????
Now for the air intake, cut out the space onder the roll bar in alli and then hand bend some strip into the right shape
Did the same for a lower intake (not to block the rad) and cut some holes.
The mesh is what I had around, probably going to change it for a better pattern.
And I still have to decide if I'll glue this to the air box or screw it to the hoop.

|Update... I'll be looking for opinions on the fuel tank later in this post, so please, fingers on the buttons. |
Starting where we left of. The airbox.
It needed a bit more hacksawing.
So now the front is more flat it received a nice multiple bent piece of alli. Glued and riveted, with the glue sealing off the OEM airbox.
Fitted to copy the hole and measure the width of the gap
So a nice hole in the box.
Then some double sided tape and 5mm PVC foam
Voila, painted and done
Then, the cooling system.
The K-series asks for some hot water from the engine to always be circulating round bypassing the rad so the thermostat would open.
Not the best design, but it needs this to work.
So had to make a conduit for this, and block off the return from the heater.
I tried for a whole day to nicely bend up the conduit by heating it and filling it with sand.
Needles to say I wasn't successful. For the time being it's going to be 90degree bends then. A bit of a sin... I know
So here it is with the water tank fitted up too
Then, the fuel tank.
So, here are my baffles. I want your opinions on the design of these. I wanted the fuel to level out between the 3 chambers quickly while refuelling
while still combating sloshing and then have only minor openings to try and keep the fuel near the pick up point.
Around the pick up there is an extra wall so fuel can come into that area relatively easy but won't leave.
It moved a bit under welding...
The baffles are quite clear now, note that I sunk the filler neck 1cm into the tank so the fuel can expand over a 20 degree delta T (I see this as a
And there she is (not yet permanently welded) , I forgot to take a picture of the pick up points, I'll do that tomorrow.
Meanwhile, do people use the nylon sifter from the OEM fuel pump units at the end of the pick ups ? Or just leave it open ?
I'm asking because you can't use a fuel filter before the pump I've heard.
The another request: Where can I obtain 70mm I/D hose that is flexible enough to connect the throttle body to the airbox ? (and doesn't collapse
under 0 bar).
Latest job was creating the fuel pump bracket and finding a place for it.

|on tonight's special... |
Crushing disappointing as no-one gave his 2 cents...
And more bodging
Without feedback I ploughed on, so this is the baffled tank with:
*A return in the foreground
*A pick up (without mesh, cause I was nervous that over time it might come undone) near the apex of the triangular slush guard
*A tube for the idiot light (reserve indicator) thermistor
*Filler neck (far away)
*Breather (near filler neck)
Welded on top and bottom to fight vibrations
Welding side plates
Welded up and pressure testing to 2 atmospheres,
man, alli is really a first time right process. Cause to fix a pinhole just welding over it didn't fix it for me... So grinding it back,
cleaning and re-weld 2-3 cm
So a whole day and night filled up and pressurised later.. no leaks
Double sided tape and foam
Bending the straps
1mm steel work
Foam backed, studs welded and done up

Well done. Keep it up

|Thanks for the kind words, |
I welcome any comments you guys would have. Since I am not afraid of redoing something and together we know more then apart.
Especially on this forum where the knowledge base is staggering :p
This time... something what every se7en owner will envy...
A nice roomy box...
That needs a tight squeeze...
Think I'll call it a boot, mind also the members that where added at the front to stiffen up the protrusion near the box.
Seriously, I measured the frequency off the battery tray/nosecone bracket structure and found that it wasn't stiff enough.
well, now it is
Then I had to find a place for the gas cap (rover filler neck)... since it's not lockable it had to live under the -locked- bonnet.
I prefer it on the right side as that is the curb side over here.
For the ignition I'm using the Rover barrel (with the steering lock bit hacked off) since it's more decent than the aftermarket ones and
it fits the RFID receiver unit. Most barrels dislike water and the RFID doesn't for sure. Meaning that if the barrel had to be in reach when
fully strapped in there weren't many locations suitable. Also the key fob had to be out of reach of my knees to avoid me getting aggravated.
Conclusion was to put it under the knee-shelf thingy but in the middle.
So starting off, like usual, with a perfectly good bit of metal... to then grind and drill it to oblivion.
And there you go, you might think it's a big lump of unnecessary weight to just hold the barrel. You'd be right but I'm planning of
attaching the relays, breakers etc there too, making use of that bit of structure.
So to allow for the new rad position the mold for the bonnet needed to be altered.
I chose to just lengthen the lip 60mm as this would make the front sit higher and the back end move backwards a bit... aesthetically it's better
(I was surprised too). That lip would have cut outs in the CFRP item to allow air to flow into the rad.
After days of alli welding I was finally getting proficient again, so decided to add the stiffeners to the mold as it has been on the to-do list for a
long time but as the sheet is thin and alli has a penchant to warp it daunted me for the longest time.
Lastly I started making weld-on-cable-tie-anchor-points for the rooting of cables.
A real labour of patience ...

|A slightly easier solution to cable ties is to bond on these things - that is what is used in many race cars |

|Not a lot this week |
some captive nut plates for the cfrp underbody.
MIGed these as with the TIG I am to prone to melting the threads.
Cut and debured
Tried to fit these nut plates by using the mold... I wasn't successful, so I'll have to invent something when the product is made.
In the mean time... I had a hover car
Most of my friggen time went to electrics, buying fuel and some coolant lines/
I must say the RAVE CD's are less then helpfull
and for some reason all the pinouts I can find are not relevant to mine
I'm posting it as a separate question in 'electrics'... I'm very happy for any help

|It has been a while, srr. |
Lots on the plate.
Some interviews on the horizon and now doing a interim job just to fund this XD
So since last time... I put her on her wheels and cleaned the hell out of the shed
Since the electrics where being tried out preliminary, I wanted to start it.
To not let the pump turn dry I used the brake bleeder to get petrol in the system.
Good news, the whole system works and doesn't leak.
So, the observant might have spotted that I was using the lights at a 90 degree angle...I tried rotating the mirrors for it to comply... no dice.
Therefor experimenting with a new position, where I planned the indicators
Air intake... needed some ''gasket''
And then a bit of a bodge. Turns out this material can take a partial vacuum, is bendy, cheap and easy to get hold of XD
And then the first wave of new bolts
