Put the pump on (the iveco pump) yesterday and got it running today. We had visitors yesterday and went out to visit some friends today, so I didn't have that much time to get it on and get it going. There were also some clearance issues for the advanced timing mechanism at the back (engine side of the pump), so I had to cut a bit out of the pump support bracket to be able to have enough adjustment possibility on the pump.
Finally tonight I got it up and running.
First impression, wow what a throttle response! Completely different from the old pump though, I think probably because of the spring that is not caged and not reinforced yet. But that will come soon enough I think.
It now revs up to around 4000 rpm-ish, I still don't have a rev counter yet.. Boost is immediately there at the touch of the throttle. It makes about 1,5+ Bar at around 2500 rpm in 5th, but the wastegate of the turbo is closed by me, so that helps too of course. NEvertheless, the old pump couldn't get the boost up to more than 1,1 Bar at 3500 rpm.
It pulls great along the rpm range, not smoking too much at all. I still have the maximum fuel screw set up against the collar that is still on the pump. first I am going to get a IC, some other nozzles, a new exhaust pipe, and a 02A tranny (has to be installed, as my clutch can't take the beating as this point, if I put my foot down to hard, it slips in 3rd, 4th and 5th) :twisted: .
So if someone wants to build a M-TDI, definitely go for one of these pumpe, all that has to be done to fit it is remove the advance timing actuator, have a custom pulley made, and take a little bit of your bracket, and she will go like crazy, with a lot of fueling reserve.
I'm a happy guy now!
