Track Preperation Part 1

Managed to get a fair amount done on the car today. My goal was to finish stripping the car out ready for the new cage and bulkhead and to also get rid of everything up front that is surplus to requirements.

So started by removing the radiator and the battery.

This gave access to the heater box and the A/C box. The mounts on both of these units where they bolt to the bulkhead had actually broken, so a good yank was all that was required to have them both out. There are also several bits of heater box air distribution trim at the bottom that also simply pull out.

I am still going to duct some cold air into the car to keep the screen clear etc, so I am leaving the air distribution ducting in (visible at the top in black) I will connect a big flexi tube to this and pipe cool air in from the standard place.

Then I started stripping the wiring down at the front. There is soooooooooo much stuff that you don�t need, so I will be stripping the loom down and removing all of the unwanted stuff. I will also be moving the fuse box and relays from under the front to the inside of the car, to make them easier to get at and change and get them away from the elements.

Then moved to the inside and started to strip the dash out. I thought this was a bit fiddly actually and I am mulling over a few different ideas to make the whole thing a bit more user friendly. I may replace the ally vertical part of the dash with a carbon strip or something.

You can see the air distribution vents there. I may end up loosing the outer two due to the roll cage front legs, but I will try and keep them if I can, as after seeing Russ get out of his car after the 1st race at Oulton, the guy was on the verge of spontaneous combustion!!! So I reckon cool air is a good thing!!

You can also see in the pic above one of the 4 alarm box modules (on the left just to the right of the left most vent pipe. HOW MANY WIRES!!!, All of this will be going and all of the wires will be stripped out. At the end of the day, I will be able to remove my ECU in 5 seconds and you don�t get a much better immobiliser than that!!

I then stripped all of the wiring from the rear bulkhead and the engine bay. Serious amounts of wires man. I hope I can bloody remember where it all goes!!! LOL.

Also removed the ECU and rear fuse box and relay box from the bulkhead, ready for it to be cut out.

Then it was out with the screen. My original one had cracked and I have a plastic one as a replacement. The guy that put this in must have used about three tubes of the sealant stuff, it was about half an inch thick in places. Cut my bloody hands to shreds and there were shards of glass bloody everywhere

Then it was out with the fuel tank. This was pretty easy, just remove the panel under the tanks and the tank is then held in by 4 bolts. Take those out and it simply falls on your head!!! One thing I will say though, I couldn�t believe how much rust was on the outside of the tank. I mean my car is a 2001 that has probably done 13,000 miles and as far as I know never lived outside. My new tank is a 70 litre bag tank.

It has two internal pumps that feed an internal swirl pot. I then connect my pressure pump in the bay and Bob�s ya mom!!! The whole tank including pumps and swirl pot and everything only weighs 6kg�s The old empty bare tank weighed 12 kg�s. Plus I now don�t need my external swirl pot and the pipeing will be a lot less and much more straight forward.

The picture above shows the top plate with the pos and neg connections for the internal pumps. The fuel return is also on the top. The fuel feed is the one on the rear side of the tank at the bottom.

Then came the most fiddly pain in the ass job of the day removing the original roll bar and removing the bulkhead. Basically I got my bugger off great electric hacksaw and just chopped the roll bar up. There was NO WAY it was gonna come out in one piece, so it came out in four pieces instead!! It was a tuff job as the roll bar is actually bonded to the bodywork, so all that has to be cut out before the roll bar will budge.

Then it was out with the bulkhead This is bonded all along the bottom edge to the ally and it is bonded down the bodywork on each side and round the rear supports of the roll bar. All of this has to be cut out and eased out. Again it wasn�t gonna come out in one piece, so after chopping it up it came out in about ten pieces!!!

Then came trying to fit the new cage. Its bloody big and weighs a tonne!!

[image]http://img.photobucket.com/albums/0903/SeanBicknell/newcagefloor.jpg[/image]

Had to fettle the sides of the side bodywork, as basically the cage has to slide in from the back dead straight so that the front legs go into the dash properly. So after more electric hacksaw action the car was looking like this

The cage then simply slid into place!!! I was pretty shocked at how well it fitted actually!!!

All that is left to remove now are the heater matrix pipes that run from the back to the front and the AC hard pipes. I would have done this today, but I needed some bits for my dremmell, so that will be the first job on Wednesday!! (have to do some real work tomorrow ( I have removed the oil cooler lines that run the length of the car. In an attempt to save some more weight I am going to change my oil cooling to an oil / water Laminova in the bay. It will mean the pipe runs are less and the laminova weighs about the same as the current oil cooler rad. I also think it simplifies the pipe runs etc. I have had no problems at all with my current setup and I will revert back to it if the oil / water method doesn�t work out.

I will also being using an oil / water laminova to cool the gearbox oil.

I guess the reason I am confident that my cooling system will handle all this extra heat is that I am completely changing the way the cooling system works. I am going to switch to an electric water pump, which means I can ditch the stat all together and the pump will simply turn on when it needs to and increase in speed and flow when the temp rises. I have taken the water pump off my engine and it is at my machine shop having the internals machined off it!! This also means that horrible metal pipe that runs from the block over the top of the gearbox will go, thus freeing up some more space and stuff.

I will post some pics and better explain what I am doing as and when it starts to go on the car.

So that was that really, quite chuffed with how the day went.

A few pics of some other goodies.

Re sprung and valved Ohlins!!

New plastic side windows

Also a shot of the business end of my gearbox. The pic below shows the electro magnetic ram, that via the bell crank moves the gear selector lever. I know the Solenoid looks big, but it is the ally case that makes it look bulky. It weighs less than the standard gear lever and cable mechanism.

Sean…

Dear Sean - you dont F*ck about do you laddie!!!

Roll bar bonded in??? No wonder the bloody harness bar was staying put!

Stayed up while stupid oclock to fit the seats and belts so I could try em out in the mornin. Rive arsed the plastic trim to get the new bar in etc…

Thought I was a hero till I saw this last post

Like the fettlin - top lad

Man!

It’s good to be insane.

You’re my hero!

PS - bet you you’ll have some leaks after that!

LOL.

No I made sure that all of the bits I “fettled” were covered by the rear clam. Plus once the new ally bulkhead is bonded in it will all be sealed and water tight.

Sean…

Fantastic stuff - & absolutely fascinating - top man

PS Did you find that bike in the boot?

Way you go Sean

Don’t change your mind though ok

Don’t change your mind though ok

LOL, yeah I have kind of past the point of no return!!!

Sean…

Bloody 'ell!

This thread proves that I’m a mechanical numpty.

Keep us posted…

fantastic detail and pictures, total respect, look forward to seeing the rest, then seeing you at the racing next year,to see the finished results.

Thanks for the comments guys!!

Nothing happened on it today as I had to do some real work. lol. Bloody custmers!!!

But I will be back on the Lotus tomorrow, so will try and update tomorrow night.

Sean…

Hugely impressed Sean! Keep up the good work. I just hope no-one makes you put any of the weight that you’re removing back in next year!

I just hope no-one makes you put any of the weight that you’re removing back in next year!

LOL yeah that has run through my head. But the thing is, the last time i weighed my car it was about 820kg’s. According to the new regs a 2.0 ltr K car has to weigh 730kg’s. So i have to loose 90kg’s but in the preperation i have to add the cage which weighs a lot, plus the extinguisher and stuff. So to be honest I can’t see how I am going to get over 100+kg’s out of it.

Out of interest, what does yours weigh mate?

…get rid of everything up front that is surplus to requirements.

So started by removing the radiator and the battery.

Um Sean!?!! Even I know I think you may NEED those!

Part of me feels vaguely uncomfortable about what you’re doing. You’re creating Franken-xige!

Ian

LOL

In the quest for less weight I am thinking of leaving the engine out and also removing the floor and going Flinstone style!!!

Sean…

820kg???

Hell, mine only weighed 785 kg after the Honda conversion, weighed by Blink on the Donny scrutineers scales.

Listen i know you are after saving weight but normally perspex windows are light enough, I don’t see bubble wrap windows, as pictured, being any good for visibility.

A very nice picture diary, that I am sure will be very useful for a long time to come. Thanks for taking the effort of doing this, just the bit on the roll cage really helps, at least now someone who wants to fit one doesn’t expect it to be a straight forward swap.

Out of interest, what does yours weigh mate?

I’m quite alarmed at how much it varies on different sets of scales but around 750kg including fuel.

I am totally perplexed at the weight of my car??? It was weighed on propper scales, they are my own scales we use for doing corner weights on cars we are setting up, and they cost me �1500. God knows. Maybe my brain is adding 100kg’s or something, but I’m sure it weighed 820kg’s Maybe that was with me in it??? LOL anybody ever wished they kept detailed records!!!

Bloody Hell, I was miles out with the weight. Called Plans today to see what it weighed last time they Geo’d it, as it was playing on my mind.

With no fuel in it weighed 751kg’s!!!

I am over the moon, God knows where I got 820kg’s from, perhaps that was with me in it???

Anyway, fingers crossed when I have finished all the striping and stuff, it will have a 6 at the front!!!

a 6 in the middle and a 6 at the end.
