Hmm, interesting. I don't really understand the differences. I do feel my Monark "273" nozzles didn't give me anymore extra power than you would expect rebuilt injectors vs. old injectors to give anyway.
Is is true that running higher pressure will reduce the amount of fuel they flow, as they are open for a shorter period of time?

I believe that any of the stock nozzles are more then capable of flowing what a max 10mm head/rotor can put out. As far as higher pop pressures, I could only assume the higher the pop pressure there might be a very slight decrease in fuel injected per stroke of the plunger. As the pressure rises there is more of a chance of the fuel getting pushed past the control collar and the mating surfaces of the plunger and head itself, it would be very minimal though.
The injectors will remain open as long as it's needed to inject the specific quantity of fuel the IP is suppling, whether it be at 130 bar, 155 bar or 180 bar.

OK fair enough, just a thought.
I'm comparing it to my other car - a Rover 45 Turbo Diesel. These have 210 bar injectors and with standard fuel settings put out 100BHP. Simply switching to the 200 bar earlier injectors running standard fuel settings increases to ~130BHP. Add a remap, and 150bhp is usual. I understand they are completely different setups though - the Rover being direct injection and using the VP37 electronic pump.

Hi,
I'm new here but I've purchased some new GTD nozzles of the German ebay. My old injectors are quite charred up so I would like to refurbish them with the new nozzles installed. But how much bar would you guys recommend? Stock is 150 bar right? Think 170 bar is a nice middle way or do you guys think its a waste of time? |

I get my injectors set at 170 bar, I have yet to run a set though.

I must rebuild my injectors and have stock pump. So the 293 are stock nozzles ? The GTD are 273 = monark nozzles ? and which are best ? I heard too about nozzles from bmw tds DN0SD318.

My project car will have 1.9 xud nozzles set at 175bar...
I put the injectors in the daily car for a few dozen miles and it was the quietest d24 i have heard. I had tried some '4S1' nozzles at 155 bar with a hope that they would fuel enough....dont go there... Standard injectors flow 35cc over 15s 4S1 nozzles st 155 bar flow 70cc over 15s Xud nozzles at 175 bar flow 45cc over 15s |
