just curious on the benefits of bigger DV holders? probly not much without bigger lines with them ehh? i got a guy that says he can machine 'em for me, i was just curious if they are worth it and what sizes are common to go with?

any info appreciated, thanks

The theory is that the small .025" hole in them is a restriction, but they are actually a valve.

I haven't seen anyone port any before vs after results between modified and stock ones. Some think they work, but no one has proven it yet.

I ran some and didn't notice any difference but I'm not pushing the limits by any stretch.
 
really, so u noticed no change at all? not even smoke/egt's?

and do the diff pumps (160, 180, 215) have diff holders?

All the Dodge/Cummins application pumps use the same style DV holders...

I've swapped them onto trucks and not noticed any difference. The gain I see for them is in a high rpm engine (sled pulling) when the fuel is being delivered in an extremely short window by 13mm or larger plungers...keeps it from bottle-necking fuel flow, relative to time being delivered
 
i did (at one time) buy some .093 holders and lines from a buddy of mine and i liked them. They did pick up the power quite a bit. YES........... egts went up but the wot s.o.t.p. was totally different than stock. Remember this was years ago.
