enough boost is when you have 3 dimple marks in the hood from the valve cover nuts..
What's the history on the pump? Any chance it's 180° out? Have you tried different accelerator lever to shaft orientations? Diesel Purge is better than ATF.
A friend of mine put a TDI head 180deg off in a mtdi pump, there was absolutely no chance to get that thing started at all. Not even a hint of combustion.
Yep AAZ camplate which was seemingly identical to the TDI one.QuoteA friend of mine put a TDI head 180deg off in a mtdi pump, there was absolutely no chance to get that thing started at all. Not even a hint of combustion.It starts well.
How much diesel do you get circulated for a minute of idle?
Tap a fitting in the top of the banjo would do it yes? VW quote 4 - 7 bar in their training manual.As for the 180 issue. My running issues don't seem to match the symptoms of those that have done it by mistake in the past.i.e. starts easy, idles smooth with no smoke and normal clatter, EGT doesn't even register on the guage (yes it does work) i'll check it though.
Mark, unless it is permanently installed, then your setup is not accurate. It is blocking the normal flow up the threads and measuring the pressure when flow is only through the orifice. Once you replace your setup with the actual pump out bolt, the flow will be both around the threads and out the orifice and consequently lower than your setup would display. While you might consider it clever it isn't functionally accurate.

I make that about 100 to 1 difference in pipe length, and so maybe 1% flow rate up the threads, I think that's right. If flow rate is proportionate to resistance. Either way it's such a small flow loss that the vane pump won't even know of the pressure gain... Better than 1% error is my submission Are you saying that the flow rate through a pipe of consistent diameter is directly proportional to the pipe's length? A 1 meter long pipe will flow 100 times that of a 100 meter pipe of the same diameter? Regardless, I'm glad you think it works well enough for you. I wouldn't recommend that system to anyone else. I'm done with this conversation.

Didn't Hagar claim he'd started a diesel in reverse
