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

Well I'd say that Calc is pretty well spot on its splitting hairs ey..

Out of curiosity what would a set of marks 24% reduction gears take it to??

someone correct me if Im wrong, but 2.020:1 is roughly 50% reduction correct?
