The strongest & quietest RS turbo gearbox!!
After months of waiting the box is finally done - well nearly.I called to see how it was going on today and took some snaps. Im sick of ripping and blowing up boxes. Straight cut was just to noisy to use on the road so, shot peened aint all its cracked up to be.
See what you think!

Bc boxes aka before christ boxes are a waste of time! ive had a load of hassle with boxes especially second hand boxes and my advice to anyone who doesnt want to waste a load of money is go the mtx route as its a fit and forget jobby! like the old saying goes you cant polish a turd lol

the bearing center is bigger than mtx75, so these wont let me down. Bigger gears & stronger material allow the box to be stronger. Bigger teeth helical cut to make it acceptable on road. the 6 speed [prototype] was built using standard shafts and gears. Before i opted to get these beasts made.
I will add pictures later of the progress and details

If it is expensive a lot of people will still prefer it as it will save chopping the car about and messing with driveshafts etc. There must be a potentially huge (relative in car terms of course) market for these if they can take some hammer.

They use special custom forks (heavy duty), syncro rings (not dog engagement) shafts have extra oil ways for better lube, gears run on rollers etc etc etc and it has an ATB diff.

Indeed how many? I know of luca's that's it tbh
400HP but there zetec and not CVH so if it's 400HP zetec most in fact all would use a MTX or something along them line's Most of 99% as karl said are running 250HP around We can use CTS 2+ box for that and it will cope very well

As above......if you were breaking stage 2+'s at Ł1800 a chuck (which a few have) then why would an extra Ł650 seem so ridiculous if it actually did the business?? It is indeed a LOT of wedge and i would also have to see it tested in some proper cars before shelling out but could be another option, certainly an easier one in terms of installation!

Isn't the BC gearbox casing itself another inherant weakness though? Prone to flexing due to the lack of webbing causing bearing failure?
That said those gears do look good. I recently stripped my Quaife straight cut box down and the gears are so well made and strong looking. Difference to the standard gears I had lying about was night and day.
