5th gear low range manual, what speed should I get at 3000rpm? ?

Mudski we are not talking beach sand here which is compacted by water. Super soft power sucking sand!

Lol.

Power makes a lot of difference in the sand. Ever seen what a turbo 4.8 does on sand?

The sand down Southend, Beachport, etc is FLUFFY and will catch the unwary very quickly

I've written a calculator for speeds in excel. The FS5R50A trans bolted to a TX12a with the stock 2.020:1 low range reduction on 31" tires will do 64 km/h @ 3000 rpm.

You're also very right about driving at speed in low - its often a necessity. I'm often on long sandy beaches and stopping to go into high is just not possible once Im moving. And on the beach I rarely go over 50km/h any way so low range is well suited. Also due to the high reduction, you've not got as much load on the motor which I find keeps the temps down, and keeps the amount of power still available up
