the search for the truth about our injectors

[Bean]

So I've been pondering about injectors lately and after gong back and forth with the manual and various sources on the net - I'm non the wiser.

I have a stock bigport EU-spec bluetop and the injector colour is blueish.
according to various sources these are 210cc low ohm (2.4Ω @255kPa (~37psi) - according to the manual stock pressure is 38-44psi though, except @idle therefor actual cc would be more like 221cc (@41psi).

same goes for the 7MGE low ohm injectors which are rated at 295cc (also @255kPa) and would there for be at 310cc (@41psi).

41psi is the average of the fuel pressure at the rail according to manual - as I don't have a suiting gauge to measure it I used that. Now it would be nice to know what the actual pressure is - I'm aware that due to age the results will differ from engine to engine or rather fpr to fpr.

anyway did anyone measure fuel pressure with the stock fpr (vacuum disconected) or could do it?

alternatively but probably more unrealistic - did anyone get the stock injectors ever flow tested and if yes what were the results and crucial at what pressure?

I'm asking all this as I have a though time to source some injectors localy as most cars around here run carbs and those who don't use side feed injectors.
If my above theses is correct I could try and find another fpr and raise fuel pressure to 4bar (58psi) which would be sufficient for me to start tuning my new engine as that should be able to support up to around 165hp. I'm not particularly a fan of raising fuel pressure as this introduces more heat to the fuel in most cases, same as a fuel pump which delivers more fuel than necessary. This as a remark for all those with 255lph pumps (100lph @3bar is more than enough to power 230+hp).

Time for a beer now hope to get some factual input back from the community.

Best regards and have a good week
