to all the really experianced ve pump experts

I have been doin some playin around lookin for high power outa my ve instead of doin my p pump conversion here are my questions.
1. the transfer pump is 4 vane. what would happen if it was machined to hold 8 vanes? more pressure more flow? or pump explosion?

2. could laser cut delivery valves and edm'ed holder be worth any power and flow like it is on a p pump?

3. would deeper cut chamber fill slots on the distributor piston be woth anything?

4. would enlarging the injector orrifaces in the distibutor piston be worth anything?

5. would a higher lift cam plate profile or duration profile change the amount of flow and power available?

6. This 14 mm head i keep hearing about where can i get one, what is 14 mm about it, will the stock delivery valve holders work, and how much more flow and power is gained with it? I wanna keep my ve and try and make some killer power i have a leaking spare pump to toy with so if it doesnt go nothin lost really. and help would be greatly appreciated cuz i really would like to beat down some common rails and p pumpers at the local pulls

1. Probably neither, just less blade loading. The blades need to be wider to have an effect on flow, and pressure is determined by inlet volume vs compressed volume.
2. Not realy, because it is a distributor style pumping element with very big injectors and rpm's over 2000 the DV's are a non issue.
3.Might, might not
4. Same as above
5. Yes
6. there is a guy on this board goes by KTA who designed and has the 14mm heads built. The plunger is 14mm vs 12mm stock. It adds about 100rwhp for most, depends on how much air ya got and injector. It is a direct replacement for the stock part.

so to #1 the higher the inlet volume i.e. larger lines larger pump the higher the transfer pump pressure? on the delivery valve question i have plenty of air so any more fule flow would have to help?? and how much for a 14mm head and when can i get one

If you want a project, you can be the first guy to supply fuel to the VE through the shut-off solenoid hole.

That's an idea that's been spitballed enough it's well past time for somebody to try it.

[ford69557ci]

then how do you shut the truck off??? get a guillotine?? and how would this improve flow or performance?

[ford69557ci]

i was readin a little on this dule supply thing. how much pressure would one need at the shut off port?

[Begle1]

I think it was around 150 PSI. Quite a bit, but not out of range.

I'd go with some kind of belt-drive pump...

[ford69557ci]

wow thats alot i have a belt drive of and alky injecter drag car but i have no idea what the max pressure is?

You can shut down just fine with the manual shut-down lever on the side of the pump. Be a member of the pull-cable club.

On a stock truck, the vane pump on front of the IP delivers all the fuel that the plunger pressurizes.

I believe that trucks with the 14 mm plunger, like KTA's Big Yellow, are capable of pressurizing and injecting more fuel than the vane pump can deliver. Hence the idea to use a second pump in parallel with the vane pump, delivering fuel through the solenoid hole.

I think that somebody had an electric pump sourced for only a few hundred dollars...

[ford69557ci]

thats why i was curious if there was any way to modify the vane pump i have a friend that is really big into indutrial air motor and in dutrial air pumps and alot of them r the vane style he knows how to get more out of them so maybe he can make that little vane pump move more fuel

Plan on big injectors too! I had a 14mm head in my hand last saturday, and the 6x18 injectors that go with it! The end of the 6x18's look like a Gatling gun!

[ford69557ci]

wow those r some big injectors i found a really killer deal on 14mm heads if anybody is interested

[KTA]

Probably some of those $60 China specials I get emails about. Too bad proper heat treat isnt in their capacity.

There were a few European sites floating around that had 14 mm heads advertised for use on turbo 4's

[ford69557ci]

these are american made and they are not for a 4cyl they are for a 6 cyl cummins
