Mac#1 Motorsport Worx Build
Discussion
I'm still waiting for the DVLA to inspect the car so they can issue it with a registration number and V5, but in the mean time I've bought a few odds and sods.
A 20psi boost gauge
A GRP aeroscreen
An ignition module add on for the Power Commander III, to allow the timing to be tweaked, that means another rolling road session to do some more mapping.

Yeah that's right I believe, it ran perfectly well like that on the rolling road, the compression ratio is lower than standard which will help, but the car will definitely be better off with the ignition tweaked.
Well after all this time the DVLA have finally pulled their finger out and registered my car, very nice to finally have it on the road after all the waiting, even more so with it's brand new 61 plate
Cooling the engine has been a little bit of an issue, so during the first few runs out in the car various things have been tested and tweaked, most noticeably the bonnet vents being added, they will be finished off with black mesh on the underside.
The boost gauge has been fitted into the dash
Temperatures are a lot better now but will need further tweaking for piece of mind during track days and summer driving.
I've driven the car a good few times now and even on low boost it goes very very well, high boost it's like a missile!
circa 770bhp/tonne kicks ass!

I trial fitted the aeroscreen tonight to see how it'll look one fastened on, another job for tomorrow.
It really is great to drive, puts a big grin on my face everytime!

Just read this from start to finish. Cracking build thread. Congrats on getting it registered and on the road. Must be an absolute hoot to drive!
Thanks a lot.It really is great to drive, puts a big grin on my face everytime!
Cheers lads
I've recently bought a set of Racetech mirrors, but have not got round to fitting them to the car yet.
Currently I have a problem which prevents me from disengaging the clutch, rendering the car useless While driving the car the clutch pedal went to the floor and stayed ther, as though the clutch cable had snapped but that wasn't the case.
I removed the clutch release lever and found it to be damaged
Here's how a new one looks compared to a damaged one
I fitted the new one hoping it would sort the problem, but unfortunately soon after the new one was fitted it was in the same condition as the old one removed, so further investigation was required.
The clutch cover was removed and the clutch stripped down, everything looked fine apart from the lock up clutch plate. The bolts which hold the bearing housing to the lock up clutch plate were loose.
Due to the fact that the bearing housing was able to move around, the clutch puller pin which locates in the centre of the clutch and this bearing was allowed to move laterally, causing it to be damaged and wear.
The nuts on the arms in the photos above are to be removed and replaced with washers and a nylok nut to prevent them coming loose, as the nylok nuts on the end of the bolts currently fitted are not fully onto the thread.
The biggest problem with this is that to get a new pin it will have to come from America, because the Muzzy lock up clutch kit is an American product, but i've found a fellow kit car builder local to me with a lathe and we're going to make a new clutch puller pin next week.

I've been doing a bit of poking around the car today, measuring, thinking and finally buying some parts to improve the cooling ability of the car.
The plan is to add extra capacity to the cooling circuit and cool the turbo cooling water by fitting a large radiator in the boot area of the car above the rear diff, push the water through it with a Davies Craig electric water pump, pull air across it with three 8" fans and finally duct it out through the top panel on the boot.
This setup should have the desired effect and also remain fairly discreet.
While I was looking at the read end of the car I took the opportunity to get some photos of the reverse gear setup fitted to the car.

One stainless steel clutch puller pin
To fit in with the new cooling setup in the boot, I need a new header tank, with larger volume and more inlet/outplet ports, so some aluminium sheet was bought and cut to size
then the TIG set was fired up and i set about joining the bits together, my aluminium welding is far from perfect but it's improving

I've been to Kawasaki Newcastle this morning to collect my parts, unfortunately the clutch release lever is out of stock and will take a few more days to arrive on back order, but on a positive note the clutch cover gasket was there, so at least i could get the clutch built up and the engine sealed up.
On the way home i called into Gateshead Bearings at Bill Quay, I needed an open 6001/C3 ball bearing for the lockup clutch plate, but they only had double shielded 6001/C3 bearings, one of these would do the job but would need to have the shields removed before fitting.
When I returned home I was greeted with a pile of parcels, opening them showed that the majority of the parts for the boot mounted turbo cooler setup had arrived, hopefully the rest will turbo up tomorrow.
One radiator, Davies Craig water pump, hose elbows and hose adaptors/joiners.
I've not done a lot of work on the car today but the clutch is assembled, cover fitted with the new gasket, new oil filter and engine filled with oil.
The header tank is progressing, still a long way to go but it's taking shape nicely

The radiator fans turned up in the post today so I trial fitted them to the radiator, to double check they would actually fit as planned.
As the weather was glorious outside, I took the opportunity to roll the car out of the garage and removed the roll bar. This made access for fitting the radiator much better, some aluminium brackets were cut and welded to the radiator, rivnuts fitted into the chassis, and the radiator mounted.
The radiator fits in the space rather nicely, happy days
Next up, the fans were trial mounted again, so the to panel could be fitted and see how much it needed to be cut to clear the three fans.
The angle grinder was fired up and a small amount was cut from the bottom area of the top panel, rested in position, clearance looks great.
As I tidied the tools away for the night, I took the opportunity to rest the roll bar back in place, this is how it looks.

Here are a few photos of the recent changes made to the car.
Racetech mirrors have now been fitted
My DIY header tank has been pressure tested, found to be leak free and then installed
With the cover on the boot area of the car, this is all you can see of the radiator/fans inside
I'm planning on joining up the large and small holes to make teardrop shaped vents, then meshing the holes from the underside, this will be done at the same time as the vents on the bonnet are meshed up.
The cooling issues are now resolved, the new radiator in the boot has done the trick
On the move temps dont go above 90 deg C, while driving in stop/start traffic through the town the temperature peaks at 94 deg C, much better than previously experienced.
