Anyone know just how strong this gearbox is??
I am thinking about buying one for a future project, but as they are expensive Id like to hear from people currently using them, and if there any problems to look for.

Thanks, I just want to see what the options are, as I will require a strong box.
The 6 ratios doesnt appeal that much, but if its strong, then Im ok with it.
It will be used primarily as a road car, but I will be drag racing it too.
It will be some time before I am ready to buy anyway, as I have to sort a new engine first.

Anybody wanna see a 1980 Granada, with a twin turbo LS6 engine ? Im getting rid of the old rover engine soon, in favour of something a little stringer, and more modern. Already have a short motor, + new forged pistons, courtesy of BoostedLS1, although just not too sure of the origins of the engine. It seems to be an LS6 block, but with a Camaro sump. Anyway, it all looks good to me
I might be ready for TOTB3, but just depends on how the finances go.

It was my Granada with the rover engine at TOTB. Im not sure what times to expect really. To be honest, I dont see myself getting into the 10's, as weight and cost are against me ( car + driver is 1580kgs ). While I may try and lighten where possible, I am not going to butcher the car, or remove any of the trim etc to do so. It is primarily a road car, and it will stay that way. It will also always be driven to and from any events.

Given a std LS6 makes around 400bhp, I see no reason why 750-800bhp shouldnt be possible. That may take a while, as I will be using some bits I currently have to keep costs down, like fuel system and turbos. This may limit me initially to around 600-650. I think the turbos will do that easily enough, but my fuel system will be at its limit, for both pump, and injectors.
Traction is a major problem at the minute, as are driveshafts breaking. I have a Ford 8.8" axle that I will be fitting over the winter, so I think this should help strength, and hopefully give me a lot more traction, alng with bigger tyres.
At TOTB, i was getting around 2.3s 60ft times at best. I have been at Crail, and Santa Pod since, but best I could get was 2.5's. But im losing traction for a lot more than 60ft.
Steve Scotts white Focus I mention in the other thread is launching amazing 1.7s 60ft times. Id like to get mine under 2s.
My car does have enough power to get into the 11's at the minute I think, I just cant get grip.
At TOTB, my terminals were consistent around 118-120mph. At Crail, and Santa Pod ( 2 runs at Pod before breakage ) again they were around 115mph, despite the huge wheelspin issues. Of the 2wd cars that went quicker, I think my terminals were higher than most.

An auto may suit a drag car, but for a performance road car......No thanks.

So far anyway, opinions on the T56 are good, and if need be it does have available upgrades which is good.

I see also the Tremec 3550 TKO II 5 speed is rated at 525lbft
If thats what they rate it at, then im sure it will ahndle a lot more, given the T56 is rated at 450lbft.
