Cam plate and delivery upgrade

[theman53]

Most everyone on here before running merc nozzles said that there was no increase in power and much smoke.

No,

Youre thinking of the very old Peugeot diesel engines, that may have been sold over the pond,

The XUD range is the last of the Mechanical injected Peugeot diesel engines, after that they moved onto Common rail in a DW engine,

The XUD uses a Swirl chamber rather than a Mercedes prechamber (which is exclusive to them as it was designed by them) the swirl chamber in question is a "Ricardo Comet" design which would seem to be the same as the VW, BMW and Toyota siwlr chamber, and the standard nozzles are definatly the DN0SD306

I have seen some rather enormous nozzles for the screw in type injectors but no idea where to get them, and the guy I know who had them has no intention of sharing his information.

BIGGER NOZZLES are not needed in a VW diesel!

wont the stock ones deliver the fuel needed?
is there a benefit to fit bigger nozzles even if the fuel output by the pump is the same?

@R.O.R
Im not talking about a VW diesel mate, its my peugeot diesel which is similar in design to your AAZ
Bigger nozzles might not be needed but it thats not what Im asking,
Putting that aside, does anyone know of any bigger nozzles?

@carrizog,
Maybe but a specific hole size can only flow up to so much... Seeing as though asking for more than double the power (and probably more than double the fuel) the standard nozzles will become an issue and i want to know what my options are should the time comr

idk how a Pug engine is set up, but on a VW, the injectors flow more fuel than the engine is ever capable of burning..

Info from a 306 specific forum, several people have now used dv's from a Nissan Terrano pump and found it much better, how I'm not sure as I'm yet to investigate myself. The first fella that did it mentioned that the hole in the peugeot dv's is tiny and hence provides a restriction, the terrano valves are larger and hence produce less restriction.

Hope this helps!

Thank you very much sir! You are very helpful, ive looked over loads of 306 and french forums and not found anything on the subject before....but ill have a look...

Ive bought an Iveco 2.8td pump pump number ending 171, can i use the delivery valves from this? They look to be bigger but of a different design and i cant part the holder from the valve.. any ideas?

[Harky]

Have a good read through the 9mm vs 11mm thread on oc and you'll see all the info!

With regard to the iveco valves, its something I don't know much about but I know if you do a 11mm conversion you do NOT use the transit valves, they may be longer or something. Hoping to get to a pump specialist near me in the next few days to see what he has!
