A bargain at £7K I went to a sadev dealer when looking for a gear cable maker.... the boxes are utter porn!

I wish they could cope with the torque :-(

[slindborg]

iirc the dealer I went to said they had some guy running a mental V8 of roader and the box fitted wasnt rated anywhere near the torque this engine was making, and it was running for 2 seasons at a time without rebuild. Although its a lot of cash to take that gamble with

Off roaders aren't going to get enough traction to load it up though. Circuit car with big slicks is a bit of a different story unfortunately. I would LOVE something like that in the Europa but with the M-32 being so robust and cheap to replace its very hard to justify a change. Also, following the Britcar 24 today, it seems like loads of teams suffer flat shift and flappy paddle failures. Good old synchro's do have their advantages!

it was also the benefit of having a diff designed for the purpose , rather than stick in an aftermarket passive jobbie. If I an going to have a LSD then I want a clever programmable one, not just oily bits. 250 lb-ft at 8000 rpm = 380bhp , map it to restrict boost and have a completely flat torque curve.

I would be looking for more like 520bhp if I were revving to 8K!

Personally I would not choose a plate LSD in a VX, the torsen type suits the chassis better IMHO.
