I'm currently building a pop tester so that I can baseline all of my injectors. Based on the following page from a Bosch Injection Pump manual, it looks like the max nozzle opening pressure for our IDI applied VE pump is ~5000 psi.

Attachment 183

This seems reasonable to me, given the pressure continues to ramp up to around 15,000 psi after the injector opens. I am planning on baselining all my injectors around 2800 or 2900 psi. I'll most likely set the timing to about 1.05 mm to start with, and then try 1.10 mm.

My goal is efficiency, not massive power production. I'm fine with losing 10% power output if my efficiency increases by 2%. I really want to break the 40 mpg mark. I'll share my results with you folks.

There are likely diminishing returns to increasing pop pressures for a given injector/prechamber design. Have you found any convincing evidence that increasing pop to 2800-2900 psi will give you the results you desire? I will be interested to see your results.

Hi, I'm looking to rebuild my D24T injectors soon, and would be tempted to give the Monark nozzles a try. I'm looking to up the power a bit, but nothing too major - definitely no drag racing.

Are these the ones to go for?

Yes, the MONARK 039 305 138 are what we have had good results with.

Ok cheers. Sorry, I've got a bit lost reading this thread - these are the ones that have seem to give smoother running and less smoke even with the diesel screw turned up?

Also, is that a reasonable price?

I didn't notice any major difference, but was running stock tune settings anyway. The finish quality looked excellent. V8volvo has more experience with these nozzles than me. He gives them thumbs up, that's mainly why I bought them. Last year I bought them at $22 and $30, not incl. shipping (different suppliers).

Default injectors

Nice thread.
What is the main difference between v8volvo's 138 nozzles and the gtd ones?
I'd like to get a set of injectors built.
Car runs great but injectors might be getting tired a bit. I see smoke that developed slowly through recent years. Everything is well tuned. Injectors may need attention.
Idk what they are btw and mileage in them is unknown.
