its a oil pump that you can measure the break pressure of manual injectors
based on a car jack with a pressure gauge

cba to make one. Cheap enough to buy new on ebay with fitting for different injectors. Handy for setting up custom injectors as well.

Why are you going M-Hdi can I ask? Why not go for 2.2Hdi with EDC15c2 (learn to remap it) control, BFO VNT, big diesel squirters and figure a way to use a CP3 pump. That would = Much power.
Also all that would be schweet in a 405 Mi16 shell

Why not. I like the ve pump. I like the idea. We've established that engine has choice for injectors. Doesn't stop me strapping a vnt to just because its m-tdi. Have to agree with Darren here. Its the best of both worlds. DI and endless adjustment fast and at home with minimal equipment
RE: Thinking out loud about diesel engine conversion - Uberderv - 28-06-2015
Not saying its a bad idea, I too like the VE pump its a thing of beauty how it works etc..... Having ECU control would just make it more refined. Once set up you can do it all on a laptop.

Soo have had a little nod from the Mrs saying that I can buy a second car soon so this may come to light in something now. Would love an old 305 but what else is there out there that I can fit an xud into for a track car build and have shits and giggles. Citroen visa......

Hmmmm. Still thinking about this.
RE: Thinking out loud about diesel engine conversion - bashbarnard - 12-10-2015
Lets talk injectors. The angle of hdi is 142, jtd nozzles are 144 i think. Some ive found are 145 for mtdi. But its not just that is it. Maybe hdi nozzles on those injectors. Can shim the first stage injection to test the second i think.
RE: Thinking out loud about diesel engine conversion - bashbarnard - 12-10-2015
So some useful info for people if they want.
Dsla p142 1477 is the nozzle on the hdi injector.
Dsla corresponds to the nozzle orifice
P is the needle type of 4 mm
The next 3 numbers are spray angle.
The last numbers are just for application apprently.
RE: Thinking out loud about diesel engine conversion - bashbarnard - 12-10-2015
so anyone got any injector nozzle ideas. i cant seem to find any

Is it really worth building a derv for track use only?

You drive yours daily as well I thought?
I'm not insulting fast dervs I'm just saying for track only it'd be more cost-effective to build a petrol car for track only to go quickly. For speed and reasonable economy yours is great. A track car does not need to balance fuel economy and suitability for daily driving against track-orientated factors.
