Can you post a pic of the fuel limiter pin out of the side of the pump, the one needing removal from the NA pump?

Certainly.



Thank you sir! Is it the long pin or the short rusty pin on the lower part of the pic? What's the best way to remove it?

How long did it take you design this system?

It's been a gradually evolving design with lots of input from others.  I think I started playing with the VNTs in 2005.

that vanagon setup looks very nice, how did you figure the spring rates for the pump lever to boost actuator arm?

jboogie13, when are you getting the injection pumps? Take lot's of pics when you do the parts swap.

n/a pump is in the mail, and currently waiting on flowmastergfunk to ship the pug pump, will definitely make a build thread for the pump as i will surely have many questions


Nothing at all different with the pug innards. I have one open on my bench right now. Identical innards. Do not use the pug cam plate, it has a smaller lift than the 1.6 one.

????????

WTF? i measured mine.. 2.3mm lift on the 1.6, and pug pumps i have..

10mm plunger, 2.3mm lift cam plate..
92 Jetta GLI - Black, 1.6D w/ GT2056V turbo..
86 GTI - 4 Door, Med Twilight Gray, Tow Machine..
86 Audi Coupe GT - Tornado Red, All Stock.. WRECKED.
89 Toyota 4Runner - Dark Grey Metallic, LIFTED!

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

perhaps there were different cam plates installed according to their application, injector combo's etc, i would measure the difference anyways just for the sake of good habits.

I have measured 2.19mm on my pug, 2.26mm on the 1.6 and 3.13mm on the AAZ.

hmm.. weird. may have to go measure again...

i swear my measurements were closer than that?!

thats pretty weird tho, they call the 1.6 plate a "2.3mm lift" and the 1.9 plate is said to have 4mm lift. or atleast thats the numbers that have been floating around..

but the Peugeot cars have DNO SD251 nozzles set @ 130bar, and supposedly a 2.19mm lift plate (i trust Jeremys memory more than my own) with a 10mm plunger...

kinda thinking out loud now, but being that the pug pump has a smaller cam, in theory, it is capable of spinning greater RPMs before roller float, right?

i doubt a smaller cam is what we need for RPMs tho..

has anyone run some TDI plunger springs on an IDI pump yet?

i think you are correct in thinking that the smaller lift would equate higher float rpm, but i think the difference would be marginal.

really wish i had some pumps to play around with!!

I measured a pug pump I have 0 460 494 159 and the cam plate lift is 4.2 mm. On the back of the cam plate is marked 440. Does that number signify anything?

the difference from the valley to the peaks is 4.2mm?!?!

and its a 9mm plunger.. weird..

Sorry, I forgot to subtract the thickness (1.9 mm) of the plate that was laid on top of 2 peaks when the measurement was made. Subtracting 1.9 would give 2.3 mm for the pug cam plate on my pump.

Some possibilities for the 2.19 mm that Jeremy measured:

1. It is correct
2. Cam is worn. Can it wear that much?
3. Jeremy's memory may be off?
4. Error in measurement

Maybe Jeremy would be so kind to measure it again?
