What should the operating pressure be on an EFI throttle body?
What should the operating pressure be on an EFI throttle body? When the injector(s) are signaled to open, the constant pressure is already there to be dispersed. System pumps vary. In general, the operating pressure for typical applications will likely run in the 30- to 90-psi range (some systems, again, depending on the application, may run as little as 19- to 24-lb. injectors). How does a multipoint injection throttle body work? At the other end of the spectrum, multipoint injection systems are available that feature a throttle body (strictly for air intake/control) mounted atop an intake manifold that features dedicated...
