Full cut delivery valves???

[BC847]

I believe what you're referring to is the NON-IC'd DVs flow a little more than IC'd DVs, below 1500 rpm.

The task there is to effectively utilize that additional fuel . . . . at 1500 rpm. I'd guess you'd have to run a 9cm exhaust housing on the turbo to get it genning at that low an engine rpm.

I get what ur saying David I was on schieds website yesterday and saw that their $1400 12mm ve pump they sell is advertised w/ cut delivery valves??? I'm going to call them Monday and see what's up w that

[oldestof11]

I believe they are modified A pump dvs. Jason can confirm.

[cummins12club]

Well I'll let u know tommorow when I call I wonder if they are buyable?

[cmann250]

I remember Scheid telling JQmile that they're ag DVs and Sheid claims supply is limited

[cummins12club]

Hmm which pretty much means they are only Gunna sell them in one of their built pumps

[Tacoclaw]

Unless you throw some $$ down, I doubt they'll tell you too much about them anyways. Giving away secrets for free isn't very smart for a business of they want to turn a profit.

[cummins12club]

Well tacoclaw u sure are right they wouldn't tell me sthi they just said its an in house affair and they aren't allowed to disclose information conceding the actuall modifying or machining process I tried to buy em even and they told me they ate only sold in a Schied built pump that better be one bad ass pump for the price and with all these secrets they wouldn't even tell me much about the pumps

[cmann250]

I may investigate next time I'm there. I have a Scheid 10 min away and I've talked to the guy that I'm pretty sure builds the 14mm about my pump

did you put your own rotor head on or did you pay schied?

[cmann250]

Neither, but they know me by name and I'm in there way too often. I don't expect them to straight up tell me all their secrets, but it's different if somebody they know asks a few general questions than someone calling on the phone.

They guy that I work for used to have a RoGator sprayer and it had a VE 12v in it. It would only make sense that those would be ag DVs

Right well u see if u look at the d valves the barrel the plunger rides in has a machined collar on the outside where the holder rides I was told to machine that down so I took them to the locall machine shop and took 28 thousands off which made the barrel no longer have the colar now I will tell u that these d valves were from a non ic pump but they appeared to have absolutley no difference when compared to my ic pump d valves I used my stock ic holders and stock ic lines and Im telling u they made a difference a little smokier but not much and my little h 35 spools quick and now their is almost no lag even w no afc tuning everything's just max I can feel it pull more and know theirs a difference I'm taking it to the track this Friday to see numbers proof it ran 16.30 before I feel that i can get it to 15.99 now but I'll let u know friday

[cummins12club]

Well ran a 15.71 last night that's over half a second to my previous run of 16.35 only changers were those delivery valves and a new stock lift pump

[Sutter1stgen]

Do you have before and after pics of the dv????? I have a lathe at work. Just want to know where you machined. Stackx2 ran a pump off of a gen set/ AG pump engine. That thing had different dv, and ran terrible. The power was in the wrong spot, and it got runaway easy. Maybe imcould talk him out of those dv since he's p-p-pumped his truck now.

[cummins12club]

Stupid me didn't take any pics but I have my stock ones still so I will try to figure out how to make one of those pics with the arrows trying to explain it with out pics is basically nothing was altered on the plunger of the d valve the little cylinder the plunger rides in is what I had cut their is a machined collar right above that bottom shoulder/collar it's shinny not rough cut like the rest of the cylinder I machined that down to the same diameter as the rest of the cylinder took 28 thousands off that's all I did cost me 50 bucks the only other mod I made between track times is I put a new stock lift pump on that's it
