Compounds. Or P-pump for better acceleration!

The Allison would give a hard no to that idea.

I did single shots and slightly bigger nozzles in one one time, and with stock ecu programming it still had enough balls to put the Allison in limp mode due to ”over torque”.

A manual trans would be the ticket. :evil
 
I told you, just go ahead and do it all. Parts list is post #145....

As to removing the pump, if some of the goobers here can do it, I'm SURE you can handle it. If you need or want some tips, I'll see if I can hook you up with someone here or I can ask and relay answers for you.

Too bad you aren't closer to Jacksonville. One of the best CAT techs I've known moved down there to take care of his mom. He started with CAT's in the Army.
 
thanks man..i can do it..just don't wanna screw it up pulling the pump or comp off. long as it isn't timed or keyed or some dumb stuff ill get it..its really good everywhere now except the huei pump area leak..

Did you find what you needed, Gary?

Do you need this piece in RED or do you need what plugs into it?
