i was told that SVO 24lbs/hr injectors are rated are 36psi. if that is true what flow will you get at 43psi on a ported TPI with a larger than stock cam?

 

It's a myth. Don't buy into all the hype you hear about it.

 

I always thought it to be about 39psi.

Anyway like mentioned in the above post it doesnt really matter. If you plug em in your gonna need to watch output of your ECM to ensure they are operating within the control of the ECM. If they are way off you have to adjust fuel pressure to get em close or adjust the injector constant seting within the chip.

I have SVO 24lbers running at 56psi but they are programmed in the chip at 23.75lbs, go figure but thats what the motor wants.

The more PSI you run the better the spray pattern, so dialing em in through the chip is the prefered method. I would never run an injector at less than 48psi, just my opinion though.
