at what fuel pressure are Bosch 30# injectors rated?

 

Depends on which Bosch.... most of the popular injectors are all Bosch, but Accel uses a different pressure than Ford for example. It would help if you listed the numbers on them.

 

SVO Injectors were rated at 39.2 PSI. Our cars run at 43.5.
The formula for figuring out the new flow rate is:

newflowrt = sqrt(newpress/oldpress)*oldflowrt

I don't have a pocket calculator

adjust accordingly to the fuel pressure you are running

Hope that helps
