Default Max fuel pressure with stock injectors?

How much fuel pressure can the stock S2000 fuel injectors handle before the either malfunction, or spray pattern deteriorates? Thanks

What is the flow of the stock injectors? I'm considering larger injectors but if the upper rate of the stock injectors is sufficient perhaps I can just up them a little.

Past 110 psi the injectors have trouble opening. I wouldn't exceed that.

Thanks David. Does anyone know what sort of percentage the injectors are running at peak? 80%? 90%?

I'm pretty sure the stock injectors are running well below 80% at peak, but I could be wrong. You could buy an OBD-II datalogger if you really want to find out. www.obd-2.com.

Just got my laptop today for the OBD-2 datalogger. I'll test on the weekend.

You might also call RC Engineering (rceng.com) and speak with a tech support guy. They may have tested S2K stock injectors and may be willing to share what they learned with you. I found them to be very helpful.
