well my opion is that you found the limit of the sc gear set mat, trouble is when turbo's come on boost its progressive weres nos its a direct hit giving shock loading on to the gears, a progressive nos shot will help but i think we have found the limit of the set, unless you can find a wider tooth set. always looking for them bigger bunches of bannanas |

The trouble with 3rd gear is that end of the main shaft has movement as its only supported by the first motion shaft. If you could eliminate that movement it might last longer. Maybe a better condition gearbox and transfer casing that the bearing areas are tighter. Paul pauls got it in one! IMHO

i know dan webster uses a dog box on the road in his KAD 1380, from what he says its fine once you're used to it. loads of vids of his car on youtube aswell if you do a search on there to get an idea what its like on the road. On 20th Oct, 2015 Tom Fenton said:

heres a q ... is a straight cut gear always stronger than a helical gear in a mini box ,bear with me lol.... if the straight cut gear has a root the same area as a helical then i would asssume it would be stronger , but if its a smaller cross section than the helical ,could it be that a h would be stronger than a sc ??i was wondering if the root of the a+gears in helical form is bigger in area than the sc gear ,sufficiently big enough to make it stronger ...any gear specialists out there that could set me straight here ?.. Medusa + injection = too much torque for the dyno ..https://youtu.be/qg5o0_tJxYM |

I know in other non mini circles straight cuts are considered weaker than helis as you say they are not as big at the base but are used for reduced frictional loss. On 7th Nov, 2008 Nic said:

Generally there is more contact with helical gears, which should make them stronger as the load is spread better.

Yes, all the truckers and bikers  Great stuff thanks for your help. bud666, yes cheers mate i'll do a seach for him. Bat i see what you are saying, the gas comes in when i want it, as it so small a shot it doesn't matter if its below 3000 rpm. and like Stevie says, I think my peak torque is about 5,000 rpm, i only rev it to around 6,500 rpm, so if i wait untill after 5,000 there isn't going to really be worth it lol :) Any way THANKS TO RICHACH GREEVES (HOGSTER) for getting us in so fast. The box was rebuilt and i got the car started today. I hope to drive it this evening, so please fingers crossed, and i might even STAY OFF the gas tonight as well LOL!

I would agree with TD (not that it matters now) the cost of replacing gears would possibly justify a better box in the long run, i feel for ya mate what an absolute sickner !! its a shame that BL didnt design some sort of damper on the gears for ultra power motors, just to take the initial shock out of the gear change when you put the power down.

I think it has been discussed before that the helical gears are stronger. The reason aftre market gera sets are SC is because they are cheaper to make in small batches. The problem is that the only helical gear sets available have rubbish ratios. I can't see how a dog box on its own will make any differance, it's not the dogs that are breaking. TD seemed to suggest that the Swiftune/Quaif DB has wider gears, which would add strength, so worth a try. It seems the limit of the MS set is reached.

the gears are wider on dog boxes which would make then consdrably stronger.

Why not get in contact with Swifty, and ask them to sell you a cheap box to "test". After all you-ve probably got the mot powerful in miles. On 13th Jul, 2012 Ben H said:
