PT36 retarder & other things

[Don Bradner]

At a guess, too much stopping power. Think about it this way: You have your
drivers turning freely, no brakes applied. They are in turn running the rear-end
and the rest of the drive train back through the transmission and engine.

Now imagine you have some ability to "clamp" down on that drive line at the
engine, without producing excessive heat, to the point that you could actually
stop it from turning. How much before you got to that point, with the wheels
starting to slide, do you think you would potentially suffer damage to some
portion of the driveline?

Our Allison's can handle 500HP, but the combination of Jake and retarder is
capable of more than 500HP of stopping power. Not enough to freeze the driveline
unless you are on a slippery road, but you could come close.
