I said 2.4x additional reduction.

You said in an earlier post "I'm wondering if direct driving Mechanum Wheels using 4 - CIMple Boxes wasn't enough of a mechanical reduction and hence cause too much draw".

If you are direct-driving 8" wheels with nothing but a CIMPLE box for gear reduction, your motors are overloaded. CIMPLE box provides 4.67:1 reduction. You need more gear reduction. Preferably at least 2.4x more gear reduction. So, 2.4x4.67 = 11.2 total reduction from CIM shaft to wheel.
