Noble M12 heavily modified
Discussion
I already have a thread running called "My Project Supercar" but I have recently put that on hold while I have a little fun with my Noble M12.
Ive had the M12 for a few years and it has been my company car iterally, I have done 40k miles in it in this time and it remained completely standard and was quite frankly an astonishing machine that was a worthy replacement for my M3 company car (the M3 turned into my track day toy after covering 160k and is an amazing car).
Earlier this year I had a slack period at work so decided to do some routine maintenance and to correct a few known issues with my model as std (weak gearbox, no track day sump etc) which whilst had never caused issue or unreliablity I wanted to do just to keep it that way.
As with all best laid plans it all went horribly wrong, I upgraded the box clutch etc and then remapped it to 400bhp... were almost imediatelly the big ends in the engine went...
So I decided to go the whole hog and put a mountune race engine it, also upgraded the box to a 6 speeder which I has strengthend, changed the clutch again (as box used different one) etc etc.. all this cost me close to what I originally paid for the car and when finished we rolling roaded it and it did 480bhp on low boost (0.9bar full boost would be 1.7bar).
We never mapped it for full power as we had some issues with the spark plugs and so I went to lemans and had a ball in the car on low boost.... upon return the engine prompty dropped 2 valves and destroyed itself due to an assembly fault by myself.... not good
Anyhow I have now decided to absolutelly mad with the car, I have sold almost all the nice parts that made it the monster spec that it was (intercooler, exhaust, turbos etc etc) and I have started a whole set of all new mods... these include developing my own single large turbo setup, developing a tripple plate clutch and doing a whole set of chassis mods (I cut the rear chassis off) and some radical body mods.
All in all its going to be a bit of a monster and hopefully quite unique and maybe a little fast
Anyhow onto some pics.
In its std guise with some stripes that I fitted and some M400 wheels.
Engine lunched itself

new clutch and flywheel helped save 10kgs off the rotating masses!!!!
some of the new nice bits ready to go on... old race spec turbo and fuel pump as examples... the race spec is 600bhp and im 'going a step further
new exhaust runs dual external wastegates which will be unsilenced
body mods are going to be kept under cover for the moment, mainly as they typically look rubbish until they are complete and painted

sorry but this is completely wrong and a common misconception... if its not less laggy than the previous spec and hold power over a significantly larger power band then I have messed up... full boost should be achieved at around 4000rpm and hold till the 8000rpm redline rather than tail off at 6500rpm as the twin turbos do.Please remember there are 6 cylinders and 3L driving that turbo wereas the little turbo has only 3 cylinders and 1.5L driving it.
Also Im running a Motec M800 with anti lag and traction control etc with totaly variable boost and traction control via the ecu...
I should point out that I am not planning on running more boost than before, just hold it for longer.

It's not lag, it's boost threshold. Two very different things. But I'm guessing the boost threshold will be quite a step. I assume you'll have a lower boost "street" map to stop it being a bit scary on the road?Edited by davepoth on Thursday 2nd December 20:59
