C16 Cat motor married to spicer 6x4

It's a C-15 in video. All depends on your right foot. Many a 9513 or 12513 lived behind some hot motors.

 

I agree it's all in your right foot. I have seen a set of boxes behind several 3408 CATS and KTA Cummins that were big horses.

 

I love that Amodel it pops up every once in a while on Facebook and other outlets. It’s just a gorgeous piece of old iron.

 

If your a good driver and easy on equipment, then no problem. Some abuse in the lower gears and weak link will show up.

As far as torque ratings go, a C15 set @ 475HP and 1650 torque is more torque than its rated for.

A stock C16 is 600HP 2050 ft lb torque, the spicer PSO140-6A is rated for 1400 ft lbs torque. the old spicer 1241 4 speed aux is rated for 12,000 ft lbs. In 1st gear 7.47 x 2,050 = 15,313 ft lbs going into the aux trans.

This says on paper it does not work, in the real world, with "top shelf" drivers it works just fine.

We need to know what transmissions are laying in the garage, there is a AMO 1750-4 rated at 17,000 lbs

 

Can the moderators merge this thread with the other? Thanks

 

Thank you!

 

Like I said, on paper it does not work. That 6 speed is rated @ 1400 ft lbs, a 600HP C16 is putting out 2050 ft lbs. The 1241 spicer is rated at 12,000 ft pounds, in 1st gear you would be putting 15,313 ft lbs into it.

On paper both boxes are to weak to handle a C16.

In the real world, with a good driver both boxes would last a very long time. Myself and some others on this forum would love to have that setup and would not be scared to work it.

You seem to be unsure of yourself, that is a huge amount of torque, things can go bad and get expensive fast. Since you don't have a burning desire for the 6x4 two stick, then just replace the 18 speed. It's made to handle the big horse. Enjoy the show quality pete with the C16 big horse.
