depends what car its on, nova MPI are external but corsas / astras are internal. They generally run on 3 bar systems but if thats on a turbo application there is the scope to run higher pressure due to the nature of the fuel reg.

The pumps dont run at a certain pressure, the system pressure is set by the pressure regulator on the fuel rail.

Bear in my the same pump is used on cav/cally turbos.... Which are 204hp as std...
