Nevermind on the 920. Wrong number it's an 841 the other pump number is still 846
 
841 is a 160/175 pump. Not sure what the 846 is though.
 
846 i believe is a 230 hp, I have that one on my truck now running as my spare cuz I'm too lazy to put the 913 back on.
 
210hp is what the spec shows for the 846 pump. Same cam as the 160/175hp pumps and a plunger like the 215hp pumps IIRC. Same gov. as the 160/175 pumps as well.

Edit: The pic in Bosch shows constant pressure dv's, but the part number is for a regular dv IIRC. It's a 127 part number dv.

I pulled my 127's and put in 191's with edm'd holders. Spill port according to the spec card i think was 3.6mm but the timing was off and seemed to be 2.4mm when confirmed with the light.
