disco pump, timing

[blackdogvan]

Monkey Magic, the AAZ cam is well documented as an option in 1Z & AHU engines. My dynolicious app will tell me the difference!! (one day...)

[monkey magic]

I've heard of 2 people running their car with the timing 180 out so it is definitely possible.

Fair enough, didnt doubt it after seeing rolo say it, but cant get my head round it!

Ref the aaz cam, it is still a non standard thing, does it time up the same as a tdi cam, or does it need 'offsetting' one way or the other? Can these be run smoke free, or is it a pure power option?

[oldskool rich]

my corrado runs smoke free, weve tried it with both cams and seems to make no difference

its got to be timing, its realy hard to get it right because no one knows where tdc on the pump realy is.

its time to reverse engineer my carrado to find out where tdc is and get this one rapped up for good

its been 3 months now on a job that should of took a day

[monkey magic]

because no one knows where tdc on the pump realy is.

When you say tdc on the pump, what do you mean? Thats thrown me..

If you have the corrado running a similar set up, have you tried sticking the serviced pump on that, and have you tried the same with the injectors, to prove to yourself they are all happy?

I reckon you will end up being right about it being timing, have you tried adjusting it by hand when running (dont fancy this myself, but know others do it) and trying to find a sweet spot?

i am happy to report, great sucsess 

it finaly works, not only does it work but having trouble with 3rd gear wheel spin, and its astonishingly fast, dont know exactly what power but well over 200 im guessing around the 220/230 mark it managed to stay neck and neck with an M5 all the way to 120mph which is pretty special think this is the winning formula

the timing was 90 wrong, the pump tdc is different to a land rover, the woodfuff key should point towards the top of the cam pully, then set it to 1.25 we are running big nozzles, AAZ cam, new K24 turbo with bleed valve, not sure of how much boost either as we hav no gauge, infact i think the valve is closed so there will be more power once we hav set it up right and using charge cooler instead of stock GTD intercooler

im so happy  i love it wen *** works, i was about to giv up too
ill try and get sum pics and vids

Glad to hear you got it sorted. I think a video proving the success is in order though.

Nice work Rich.

Really nice, I'd like some video's of this basterd.

That woodruff key setting, is that valid for all LR-pumps or is it just your custom pump?
I started to think about it when burn_your_money said 180 degrees, I realized I actually have no idea where "TDC" is on my pump... 

[oldskool rich]

all 3 of my land rover pumps work like this, they are unmodified apart from the govener

we got carwoods (diesel specialists) to rebuild the pump back to standard and lock it at TDC which they did, we tried it and it still didnt work, it turns out that it was 90 degrees around from where it runns on a landrover. we only found this strait away on the rado because we machined a VW pully to fit the pump and we actualy used the woodruff key and drilled out the pump so we could twist it to get the timing right, we used the timing hole on the VW pully to work out where pump TDC was, on the golf we had adjustable pullys made up and then we had been running what we thort was landrover TDC assuming it would be the same

landrovers have bigger pullys and it seems the pump sits differently so the pipes must run differently too

but officialy on a VW point ur key towards the top of the cam pully and work it out, ull be amazed 

im taking it for a test drive tonight, will let you know how it goes, hopfully ill get sum vids next wk, the owner works for MR2 tuning company drives 700hp car on a regular basis, if he says its fast then i believe him

[svenakela]

Thanks for that.
So, to make it all happen, which outlet on the disco pump should go to the first cylinder on the VW engine?

what you do is set your engine to TDC ,timming belt of the fuel pump turn the pump by hand with spaner clock wise and with your other hand pumping your primming builb with the ING on (power going to your stop solanod)and have no1 fuel pipe slackend at the injector , stop when you see fuel coming out no1 at the injector pipe, put the belt back on and time with dile gauge , or by ear as what i do

I do know that.
What I meant is that there's nothing that says that the fuel lines are in the same order.

[snakemaster]

 think vw is 1342 fireing order  land rover is the same as vw cos i have fitted a LR 11mm head on a 1.9 aaz pump and used the vw 1.9 tdi  hp fuel lines and there was no prob with fireing order and run sweet

[blackdogvan]

Same, as long as you mount it the same as the VE that came with your car. I swapped out the LR delivery valves with a set from a AAZ pump. The LR's are longer & caused the shown injector line issue. I would have just bent them but I recall reading somewhere that the plating on the inside that could flake off & plug injectors.

[burn_your_money]

The firing order out of the pump is always the same, ABCD(EF). As long as you are using the lines from the engine you won't have a problem.
