Well done mate what a machine!!
The noise is incredible it sounds like a jet engine does it have an afterburner?
Good luck at Silverstone try to keep it in one piece although at least you won't get another White knuckle ride with me driving it!
definatelly goes like it has an afterburner lolThe noise is incredible it sounds like a jet engine does it have an afterburner?

shame you cant make it mate...
on track at silverstone tomorrow so hopefully some track action videos to follow... just plumbing in the low/high boost switch in case it rains lol.
Have to say its amazing how well the car hooks up... considering it has 500ftlb of torque for over 2000rpm and bearly tails off till redline!

I promised a clip with drive by... I made this quickly, there is 3 dyno runs starting low and working up to the big run.
There are 2 drive bys... I was pulled by the noise police on the first tine out so I wasnt allowed to use full throttle keeping my wastegates shut and thus the car quite... the first drive by is with me on 3/4 throttle with car quite and the second was my last few laps so was at full chat
I will be getting a silencer made for the wastegates so I can fit them on track... not needed on the road as the wastegates only open on full throttle above 5000rpm and if Im doing that on the road Im not worried about noise
My driveshaft issue turned out to be the problem I though it would be but didnt ruin my day... I have a shorter one on order and definatelly need it prior to my next track day.

Screamer pipes are effectivelly a separate exhaust system....on a turbo car you have a wastegate per turbo and this opens to allow exhaust gasses to bypass the turbo otherwise the turbo would massivelly overboost and overspin destroying itself and engine in the process.
usually these wastegates are built into the turbo and simply bypass the exhaust gasses directly back into the exhaust in the same place as all the other gasses.
Mine is different in that I fitted external wastegates instead of my turbo having them built in, I also have 2 wastegates for the single turbo... and I have then routed them direct to the rear of the car so these are the two extra little pipes you see. This means that when the turbo really starts to spool up the wastegates open and gasses will be bypassing not only the turbo but also the entire exhaust system and silencer.... effectivelly under full boost/throttle my engine becomes unsilenced.
Also means that low boost is louder than high boost as the wastegates vent more of the exhaust gasses to restrict the turbo to 0.6bar rather than the 2-3bar its wanting to produce.
The flames are simply fuel going into the hugelly hot exhaust and igniting causing flames... the rev limiter cuts spark but some fuel still goes in and goes straight into the exhaust... the manifolds get so hot that despite being 2mm thick stainless they go beyond red and become almost translusent, quite amazing to look at actually.
My eventual goal is to run anti lag and launch control... this means we actually deliberatly overfuel the car during gearchanges so that the flames keep the turbo spinning... its amazing to hear and see although very destructive to the turbo and can make exhaust temperatures rise to silly levels.
But lets be hounest... it would be rude not to

Right winter is here and so the car is in line for a new list of Mods... after all be rude not to.
So this winter I am doing the following and will follow up with pictures as it goes.
1. re-fit tripple plate clutch after lightening the flywheel even further, balance entire assembly
2. fit all new heads slightly more breathed on than my current mountune modded ones.
3. play around with ceramic coating of the heads and pistons (not doing the tops of the pistons though).
4. Fit motec M800 ecu
5. Inconal exhaust manifolds (wow these are expensive)
6. wrap petrol tank and everything fuel related
7. Fit all new dash after covering in leather (re-modeld a spare I had)
8. new seats
9. New stack dash with alerts to replace all the clocks, includes boost, fuel pressure etc.
10. new wheels saving 9kgs in weight
11. fit new rear clip with all the body mods (cant wait for this to be finished)
12. colour change
13. water/methanol injection
14. sensors on everything into the ECU from fuel pressure/temp to EGT
15. remap to multiple settings ie road/rack, wet/dry, high low... happy button overboost
16. New private plate
17. new front lights to my own design (leds etc)
18. lightweight battery
maybe's include if the above hasn't bankrupt me
1. fly by wire throttle body
2. new inlet manifold with jenvey trumpets
3. traction control
4. double din sat nav (already moved the stereo to the center console)
the goal is a real 700bhp and a 50kgs reduction in weight (to get a dry weight under 1000kgs) and a move towards a much safer engine management with option to do traction control and anti lag as mentioned earlier in the thread.
Since the last updates I did have a silencer made for the wastegates so that it passes drive by's on track... this worked a treat but is removable so I can have straight through on the road as it does muffle the wonderful noise they make lol

I already have the Motec M800 so money already spent and not looked at anything else ... its interfaced to the stack dash already so i'm not going to change
Ah ok, its very good anyway. Apparently they have just released all the extra add on features for free now?djt100 said:
Andy, Are you still building the Supercar ?? would love to see an update on that thread
that is still sitting in my garage awaiting me to do more work on it... thinking of scrapping the bmw V12 and using a bmw V10 as I recently bought an M5 and the engine is epic and revs to 8250rpm so perfect for my GTT and with some turbos and internal work I recon I could get 1000bhp from one GravyScape said:
Bump for interest
not updated this thread for a while as I have a thread on the noble forum that I update... anyhow I have been busy on the car... I decided to teach myself how to make carbon fibre parts and then made the rear clip from carbon.Standard clip is over 30kgs... my new self made carbon one is 9.6kgs with some trimming still to do.
I also made a new dash and have had a loom made so I can fit the Motec M800 ecu I want to run the car with and I will then push the power up a little as it will be monitoring everything properly... its also having a complete colour change and I will be having my trademark stripes over the car in exposed laquered carbon, obviously the rear clip is easy seeing as its entirelly carbon but Im not replacing the center tub so I had it taken back to gel coat and infused genuine carbon onto it making it a composite tub rather than wrapped one lol.
Also bought some new lightweight wheels and a new massive rear spoiler as used on some Corvette GT race cars Im told.
anyhow pics.
Ok well lets be clear I had no experience with carbon until 2 months ago, so this is me teaching myself... get the right products and advice and its achievable by anyone.... break down each stage of what I did and it doesnt seem hard.. polish a part... then apply wax... paint some gel coat on.. etc etc
Also remember Im actually just a bean counter, if I can do it, anyone can lol

been a while so thought Id update.... lots of work has been done to the car over last year and Im still getting it all together... most significant think it still needs is paint but that will have to wait till next year.
Engine is now running on the Motec ecu... mapping is still ongoing especially around idle as I have removed so much weight for the flywheel and clutch (10kgs) that the revs rise and fall so quickly its hard to control idle when the car is blipped... I have just fitted an idle control valve and will be mapping this in over the coming months.
I fitted new spec pistons and these seem to be giving a better power and spool, on low boost its running 382hp at the wheels at 0.6bar flat... I ran 1.6bar previously.... we have not mapped it beyond 1bar yet due to a turbo failure on the dyno but while the turbo was failing it did make 500hp at wheels at 1bar flat which is only 75hp down on what it did previously at 1.4bar so I should see my target 700bhp at flywheel as Im only just over 100bhp shy already.
Carbon clip came out well, I have made an all new way of hinging and holding the clip on the car so that it can take more downforce that the rear wing generates.... Ive also remade the interior fitting by remodeling the dash and making yet more carbon interior panels... also had the door cards covered in a 2 tone leather to match the dash which is leather clad.
Had the car on track at low boost and it was very quick considering the low boost it was running... still got issues to iron out that I am gradually working my way around... fitted electric windows last weekend by removing the entire noble mechanism and fitting a heavily modified one of my own... even saved a bit of weight in the process.
should be noted that I make the carbon stuff myself and its all lightweight vac bagged... I saved over 15kgs on the rear clip alone.
anyhow here are some pics...
first fit of the rear clip and temporary perspex rear window

As per above... speak to Matt as he was a wealth of help and expertise.http://www.easycomposites.co.uk/
its not the cheapest thing to tool up in... and be aware you may end up with the bug as I make everything from carbon now... even planning my own design of full carbon seat
great skill to have though as carbon is bloody expensive mostly due to the labour involved in making them as its not a fast process and cant be rushed.
colour is undecided and I am open to suggestions however the stripes over the car will be in laquered carbon though hence I have taken the paint on gel in a strip over the front and tub and bonded carbon onto it (yes I vac bagged my car lol).
Guess what? after making the rear clip I decided it would be rude not to do the doors and front clip in carbon as well... so I started with the passenger door.
Pretty please with results, I layed up a lot of material (carbon and Kevlar) to make sure it added some extra side impact.
I've made the mould for the inner panel, but not yet pulled the first part.
So its confirmed... I officially have a carbon fettish

carbon is 1/3rd the weight of GRP of same strength... Ive made this skin a lot stronger than the standard one for some extra crash protection so I expect it to only be half the weight... my stock passenger door weighed just over 9kgs totally stripped.
The BMW V10's do sound soooo good... I did my own version of a silencer delete on my E60 M5 and it sounds increadable, Im actually tempted to put some induction air filters on just for the induction roar... the induction raw on my E36 M3 sounds as good as the exhaust which is whats making me think about it.
Finding the time is never easy, especially as I spend half my life overseas with work... however its my R&R, I dont feel relaxed sitting in front on the TV or generally doing nothing and I need my R&R with the job I do else I would burn out very quickly.
Having said that Im not making as much progress as I would like... going to start the moulds for the driver door and hopefully paint the front clip in preparation for moulds this weekend.

aol stopped providing web space so a lot of the pics have dissapeared although I do have the backups i've not re-established it in 4 years lol.
