Wanting to upgrade nozzles on a pd130 to dssr 130% what bodies are best to use I hear the bew bodies flow better through the channel is this true
PD150 and BEW bodies are the same (8mm) if I'm not mistaken.
Well there ya go, thanks for clearing that upYou are.
Is there any evidence that XX injectors and better then YY? I've always assumed BEW and PD150's were identical (sans the nozzles)I heard PD105 1.9 bodies were the best, but I have seen no supporting evidence or statistics about them. I'll be a little gutted if so as I would appear to have sourced a set of injectors for my DSSR 130s which were not optimal.
I think it's better someone to confirm that US BEW and European BKC (PD105) have identical injector bodies...Can any 1 confirm the part number of the bew injectors I need
X2 I've got some pd 105s to change from my 150s if there is a gain to be had!So, has anyone actually bench tested the AG (pd105) vs the AL (pd130/150) with the same nozzles fitted, for comparison purposes?
I don't fancy looking in to the AG bodies for my car unless there is a proven gain. Plus it would mean time off the road and more garage and united diesel labour to take my 130s off my AL injectors and fit them to AG injectors.
This is the kind of thing that I am sure Keith at United Diesel would look into if requested. I've spoke to my mapper who said that they may flow a little more at the bottom end but past 3k they flow the same.So, has anyone actually bench tested the AG (pd105) vs the AL (pd130/150) with the same nozzles fitted, for comparison purposes?

Absolutely correct.definitely NOT identical.
There's more to it than just "plunger size" internal flow path is different (more twisted and convoluted on the "non BEW" = restrictive) and internal restrictor plates also. Non-BEW are essentially throttled by design. BRM is worse because of small piston. BHW is non-BEW.
Going to BEW (or maybe even 105 hp) bodies vs PD150 is good for more hp. Seen this over and over again. Guy using "special imported Euro 60k miles" PD150 injectors with R783, 190 hp. Other guy, same everything, same tune, same turbo, same nozzles, same everything, but BEW injectors, 215 hp. Never fails. More power with BEW vs PD150.
I was under the impression the BHW injectors are 8mm. Did you mean BRM?...The US BHW (7.50 mm) injectors use a higher flow set point to offset the lower volume and peak pressure...this forces higher peak pressure thru slightly longer stroke range, but this greatly limits peak delivery volume since the effective stroke is less by virtue of the narrower high pressure plunger bore. These use similiar nozzles to the BEW however the key limiting factor is the smaller pump section...
Got a Bosch reference for that statement?The PD150 uses the large 8.00 mm bore and higher flow nozzles. However they limit output in the primary hydraulic channel. This was per Bosch to make it probitive to tune or modify the ECU for greater after market performance.
You want pictures of the restriction circuit? its a designed in limitation that cannot be swapped out...Got a Bosch reference for that statement?
