New Gearbox for M12 owners
Discussion
I've been working hard to produce a stronger gearbox for the M12 and am pleased to announce its now available.
The box uses a Brand New M12 6 speed gearbox, fitted with stronger bearings and a Brand new Quaife ATB
The Gearset is Hardened, shotpeened, polished and super finished.
This gearset finishing process has been perfected on another gearbox project I have been involved in
The box is also modified to take an oil cooler which is essential to protect the gears, bearings and fork selector.
I can not tell you exactly how much HP/Torque this gearbox will take but I can tell you there has never been a failure of the other type of gearbox that has been developed.
the price is £3000 all in - but does not include the oil pump or cooler
I'm working on an oil cooler that will fit in the side air vents neatly
I have also been asked if I can produce a box with a different set of ratio's - this is possible however i will need probably 20 - 30 orders to make it cost effective
Hope this helps

Ciao Gadgeroonie!
As soon as you can have an idea of the maximum torque it can resist let us know.
My car has a very strong engine by roush but we had to limit the torque on the old gearbox, even on mine we've fitted oil pump and cooler and after a lot of track days all seems to be fine at the moment.
Did you change the metal kind of the gearset?
Thank you for replying ciao
Marcello.

A clutch that'll take 500ft/lbs would be handy too.
To be honest, without someone having the standard 6 speed fail, and have it in bits to find exactly why, we're just as much in the dark. Everyone goes on about torque related failures, but who's actually had one? I believe a couple of 5th gears have been lost in racing, but that's racing for you! Big jump over the curbs with your foot planted can cause the strongest things to break.
I'm not trying to rubbish your efforts Mike, as we need people like you pushing this forward, but the question is, are we trying to fix a problem that doesn't actually exist? I don't know, and as ever, happy to be corrected.

Hi Phil
yes - I think the Gearbox in the Noble is probably a lot stronger than we realise
however if you speak to some of the Noble service centres the failures are probably more common than you might think
lots of the owners in the USA have been pushing the power and there are quite a few reports of gearbox failures there too
I have a clutch lined up for the box also

In fact quite a few have gone, most commonly 5th gear. What Mike's doing is a definite advance, I'd like dog engagement next.
Well done mate, I just wish he'd do re-furbs as well as selling whole new boxes.

Paul,
Have you actually seen one of these failed gearboxes? Any pics? I´m interested too, to know exactly what breaks. If it´s stripping 5th gear, then something is obviously wrong with the gear as first and second have the highest stresses on the teeth. Bearings? do they fail first and cause reduced meshing on the gear?
Otherwise all we have is hearsay, and another urban myth gets stronger....

the problem with a rebuild when the the bearings have gone is that the gearset will have been damaged - you may not be able to see the damage by eye - but there is a good chance the gearset will fail in the future due to this
so the only thing you would end up rescuing from the box is the casing
Noble will only sell new boxes - not parts - so it is not possible or economical to repair a damaged box
Hope this helps

Ah - did they make a 3.0l ST220?
I was just going on the fact there was only 5 gears on the ST Owners club specs for the ST220...
www.stownersclub.com/models/st220.htm
Mondeo ST220 MTX75 Gear Ratios
1st 3.417
2nd 2.136
3rd 1.483
4th 1.114
5th 0.902
Reverse 3.620
Final Drive 3.560
