Well I had my pump on our test stand at work to do a recalibration. At 21mm it did 451cc's with 191's and no plate.
I used stock 131s(160hp 841 pump), 191s, and we had some 024s in stock.
Im not sure these are the same 024s as everyone loves because they didn't perform how I thought they would. Bosch Part # is 9418270024.
Left = 024s Middle = 191s Right = 131s
EDIT: Previously stated that those were not 24's but it seems that there are too many differences between companies to truthfully tell if they are 24's or not, they can vary in flutes, pintles, taper, and shoulders. Learned something new today.
Interesting to see that .003" diff of shoulder hight makes just over 5cc's of difference in flow. Might be able to crunch some numbers and find out how much shoulder would produce diff flow rates. Was wanting to do this myself but you beat me to it.
Would you be able to do the 131/181 combo?
I would like to see across the board results for 131, 181, 131/181, 191, 24, 22, and lazer cuts.
oh and you may wanna edit the shoulder measuments, you put 181 instead of 131

those are not 24's. The shoulder on 24's is .024".

I thought the .024's were a .024" shoulder also, but this is the part number I found and same # works with 022 on the end. I have access to test stands at work and will be doing another pump next week or the week after. I would really like solid numbers on all dv's available, but I really don't have the money to buy a set of each and test them. Im interested in the accuracy of these 024s compared to what everyone else is buying from peaks or others. This test just didn't seem to support what everyone is saying about 024s compared to 191s.

On CompD "DDP Magic DV's"
Shoulder = .76mm = .02992"
It can be easy for 2 people to measure something and get totally different results, but his measurement is closer to my .033" than .024".

On second thought if everyone wants to send a sample dv to be tested. My old boss and I will be building my 13mm pump. I'd be willing to foot the bill for shipping and testing so we could get some accurate cc differences. Say 131, 181, 131/181, 191, 022, 024, ddp, full cuts, sdx comp.
