Mac#1 Motorsport Worx Build
Discussion
I'm still unsure as to fitting a full cage or not, hmmm, plenty time to think over the winter months.
Yeah, they're Powerlite calipers, they work really well with the sierra master cylinder, no complaints here.

Hi
Great build!
Can I ask if it's the powerlight calipers you have used front and rear? How do they feel on the standard Sierra master cylinder?
Cheers

A bit of an update...
Unfortunately the new clutch puller pin has broke, looks like the stainless steel was too brittle and has sheared.
A new puller pin has been made up from EN24t steel, it has an extra shoulder in the centre to locate in the original clutch cover bearing, and here she is...
In a bid to stop breaking puller pins, I've removed the weighted arms from the lockup clutch plate, so the clutch now operates as a standard clutch. The car now drives a lot better than it did with the lockup working, but the problem is the clutch now slips while using high boost.
To try and combat the clutch slippage I've bought an EBC heavy duty clutch kit with uprated springs, this will give more friction and more clamping force, so hopefully do the trick.
If the clutch still slips while running the EBC kit, it'll be a case of fitting the weighted arms to the lockup plate with no weights, try it and if required add weights until the clutch does not slip, trial and error stylee, trying to use as little a weight as possible to allow the clutch to grip.

what Tig machine did you go for/use? I fancy getting one to learn a new skill.
It's an R-Tech 200A AC/DC set, I've had it about 5 months now, great service from R-Tech, I've used it a few times and I'm happy with it.Here's a link to it on their website...

I'm impressed you managed to weld up that tank from simple flat bits of ally - when i tried that method it warped like mad, although it was an entire fuel tank i was trying to make.
If you look at a tank a pro has made you will notice they minimise the amount of joins - so fold up a box from flat plate and then attach the end plates:
On the end plates, fold a return onto them (that goes inside the box) - this gives a solid surface that wont warp when it gets hot:
On my tank i added a 4" deck plate, which allows me to get inside (and to add ice if you wish)
Oh and you need 5% magnesium rods on NS4 ally.

Good luck with the TIG welding Jason. 
Thanks for the info eliot.
Here's a little update as it's been a while since anything has been posted in here.
I've had a new clutch puller pin made and yesterday I rebuilt the clutch using the EBC friction plates and heavy duty springs.
I have also refitted the weights and arms to the lockup clutch plate, so there is no reason why the clutch would slip while running the higher boost setting.
To overcome the issue of not being able to press the clutch in with the lockup clutch while the engine is doing high rpm's, I have invested in one of these
http://www.flatshifter.com/flat-shifter-expert/
The Flatshifter Expert quickshifter provides effortless full or part throttle clutchless upshifts and auto throttle blipped downshifts without using the clutch, so the car should be a real pleasure to drive once I get this kit strapped on, it should make it a tad quicker on track too according to Flatshifters claims.

Hi mate
The flatshifter kits are ace I've recently fitted one to my mac1(you've been helping me out relocating the oil filter on another forum) I went for the pro setup with paddles, I recently did a track day at donnington and it just needs a very slight amount of set up to get it perfect, the blip on the downshift sounds awesome, banging down 3-4 gears as quick as you can physically move!!!, I had loads of guys come over to my garage to comment on how it sounded downshifting Into redgate the car certainly feels quicker with it fitted.... Cheers.....

Thanks for the feedback, it's always nice to hear from other users how the product actually performs... i'm dying to try it, just can't be bothered to fit it at the moment, lol.
I've been doing a bit more testing today and found that my car, while carrying a passenger, is a shade slower than a friends 154bhp@wheel GSXR1000 through the gears, i'm rather pleased with that

Yeah I bet !!!!! I had a run out late summer to abberyswyth on way back I had a good dingdong with a few fireblades through the valleys, they were quicker than me but took um ages to get past I thought it was real good fun!! Pity the mrs didn't agree!!!!!
I'm really looking forward to suprising some bike in the summer My wife's still not even sat in my car yet, lol.
Finally fitted the Flatshifter Expert kit yesterday, tested it in the garage and the blipper worked a treat, with the engine at idle changing up and down the gears without the clutch was easy, if a little jerky, but the fitting instructions mentioned this.
I've been out in the car today, first drive with the Flatshifter on the car, going up through the gears is so quick it's fantastic!
changing down the gears while carrying reasonable speed is silky smooth, at lower speeds it's not quite perfect but this can be fine tuned to suit your personal preference.
All in all i'm a happy man
The car's booked in on Monday for a mapping session at Daytuner in Harrogate, a set of NGK Laser Iridium spark plugs and a Power Commander ignition module to be fitted and maybe a touch more boost, maybe up to 15psi (1 bar)... wonder what numbers she makes?

It was high time the horrid ratchet strap over the inlet manifold was removed, so without further ado it was taken off.
The motor/position sensor was also removed from the throttle bodies secondary butterflies, this made a nice space to allow some straps to be fitted to secure the inlet manifold down.
Some aluminium strips were cut, bent and drilled, once fitted to the engine they look like this
Looking at those last two photos, the wiring and vacuum hoses need some tidying because they look a bit messy.
As agreed with Damien at Daytuner, the Power Commander has been fitted to the car but not connected up, that will be carried out when I get there.
Oil and water levels checked, tank filled up with V-Power, crash helmet and warm clothing sorted, that's me set for the trip out tomorrow... fingers crossed the weathers good and the results are even better!

Mines like that I don't up or down shift without the clutch unless I,m giving it some stick I fitted the pro set up on mine which I believe is even more aggressive, looking forward to seeing ur results from the remap, cheers

Here she is strapped on the rollers at Daytuner Performance
Power Commander Ignition Module connected up and then fueling/timing adjusted on low boost, the end result 198bhp/101lbft@wheels (iirc), waiting on the graphs being emailed to me, when I get them i'll post them up.
The power is about 10% down on what was measured at BigCC, don't know if that's just purely down to discrepencies between the difference rolling roads, but the car runs and drives a lot better since being tweaked with the ignition module.
The problems began when trying to map high boost, the manual boost controller seemed to be acting up and not controlling boost, meaning it wasn't making any decent power at the top end of the rev range, so the plan is to buy an electronic boost controller and go back to complete the mapping.
At the moment the one i'm liking the look of is the Turbosmart E-Boost Street, anyone got any experience with them?
