After calibrating so closely, how did the car run?

The four injectors were within 4.5 bar before adjustment, and within 1.5 bar after. There was no perceptible change in how the car ran after adjusting them this closely (they were reasonably well matched to begin with).

What are you guys using for shut-off valves? The cheapest one from McMaster-Carr rated for 2000psi is ~$35 (4024T71).

I am in the process of building a pop tester based on Cornblatt's design. However, I read in some MB manual that the valve functions to control the rate at which injector pressure increases thus allowing a more accurate reading of pop pressure. I'm thinking that to accomplish this, the sequence should be: bottle jack -- valve -- gauge -- injector. This way the gauge reading will be the pressure at the injector side.

The pop pressure procedure would then be:

1) Pump bottle jack with valve closed.
2) Slowly open valve to increase pressure at the injector side. The gauge should then show increase in pressure.
3) If pressure is not enough, close valve, pump jack and then slowly open valve. Repeat until injector pops.

I will build mine this way and let you guys know how it turns out. The only problem is that I am having difficulty finding 6mm OD Merc injector lines. Another option is to obtain an old delivery valve holder so I can temporarily use one of the injector lines on my 300D. Anyone have a spare injector line or delivery valve holder I can buy?

I have 5 Monark nozzles from C. Sean Watts that I'm itching calibrate and install.

What about making opne for the old type petrol none electric injectors .Would the idea be the same ?

Is there an advantage to using a liquid filled gauge vs a dry gauge? My Bosch pop tester came with a couple of dry gauges but I was debating getting a liquid gauge.

Hello I know the thread is quite old but someone can help...
What does Cornblatt mean by tapping,? Just screw the adapter then tapp it by hammer? Doesnt it damage the thread?? Thank you

thread tapping = cutting threads
