[Mgs] OD Query

[Dodd, Kelvin]

I'm setting the MGA up for drift racing, so want to make sure the rear
end will hold together under boost when the MP62 blower kicks in. Figure
about 160 ft lbs of torque at about 3500 rpm.

	I haven't found the flange area on the solid wheel axles to be a
particular problem, but I have snapped two axles at the inner end, both
with coarse spline, which I am convinced is weaker. I use fine spline in
the Jamaican and I am not a young drag racer so do not submit it to hard
standing starts. Hopefully it will serve me well.

	I suspect that the fine spline axles in a Banjo axle would also
work with the Miata - my race MG engine puts out more torque than they
do and I've been getting by on coarse wire wheel style with it.

	The late axle is around 50 pounds of extra unsprung weight as I
recall....
