Limeted Slip Diff and "Axle Tramp"

Is it possible to still get "Axle-tramp" with a LSD ?
I have a mate who is getting tramp at the drags,yet I was under the impression that a LSD wouldnot allow this ?He is running an IRS setup on a T3 fastback. Should he support the motor still ?Any feedback would be appreciated !

Hi,
IMO, the bounching of the wheel (wheel hop) - if that is what you mean by axle tramp - is caused by the short slippage of one or both wheels and then regaining grip.
Wheel hop can be avoided by making sure the engine is firmly attached to the chassis by a brace or extra monting point(s) and then also good shocks should help.
A LSD will only avoid wheel slippage to some extent between the left and right axle. This comes in most usefull in corners, where otherwise the power is routed to the wheel with the least grip, usually being the inner wheel in a corner.
With a drag start, I imagine that when one wheel wants to slip because of a twisting engine that causes unequal traction, LSD will prevent some of the slippage, but not all (unless it is not a 'limited' slip differential, but a 100% slip differential) and certainly not wheel hop of both wheels, which can also occur.
I hope this makes any sense to you.
Greetings,
Walter

The engine/trans needs to be mounted very securely for drag starts. Any flex in the mounts will allow movement which causes wheel hop or "axle tramp". A rear engine brace will definately help.
