valve train

id like to see what AKI is doing to get 7000 rpm out of one.

[Rabbit on Roids]

thats probably exactly what it is...

[RabbitJockey]

thats a fancy looking pump almost like a bosch p series fopund on cummins 4bt's

it could be one for all i know i just got it off google haha.  i just wonder if that would be better for revving.

[burn_your_money]

i wonder if an inline pump would do the trick, but i guess they could be worse

I would think they would be better because each cylinder has it's own plunger so it would be cycling only once per engine rotation where as an inline is cycling 4 times.

I think you mean a Rotary is cycling 4 times per engine rotation there Tyler. lol

and you work on these lil buggers!? Could never tell lol.

Btw im just bustin' your balls for fun lol. Inline pumps are pretty cool, one plunger per cylinder.. so theoreitcally they should be able to fuel 4x as much as the rotary.. assumg it could stay together, have an engine to fuel, and suck in that much fuel LOL... its bed time i think.... lol

[smoken u]

hmmm inline pump should be able to stay together, like you said 1 piston and delivery valve per cylinder, as for fuel you could use an electric lift pump like a fass or aeromotive pump to supply the fuel that the pump would need. another idea is common rail but there are alot electronics, and computers that are involved in that. kinda takes the simplicity out of it lol

There is at least one documented TDI engine using an inline pump for a tractor-pulling vehicle.  As far as I know, an inline pump mounted to a VW diesel will not fit under the hood.  I'd sure love to see someone try it though.  The VE pump is the weak point of these engines.  I know they are capable of putting out a lot of fuel, they just aren't very good at it.
