What is a Slipperential?

[superek4]

need to check with u guys for the speed calculator under scriptasylum to calculator the 46t slipper diff do u input under the transmission gear ratio under 44/20 or under 1/1 direct drive?

I get 20km/h when I input the slipper diff, if I input 1/1 direct drive I get 48km/hr.

I thought slipper diff is not a differential diff? So it shld be 1/1? Pls advise wat I input wrongly thx.

My input was CRT 43/13, 46 spur, 11pinion, holeshot lrp truck tires, 1600x70mm medusa motor, 4s 5000.

Pls advise thx
