5-port manifold and the accumulator will take care fo the beat
frequency- the system run extremely quite and smooth.

Thanks, i was thinking that two pumps each with its own HSV, could be activated at seperatly at different times, using separate pressure switches. Do i need two FIA 2's or would one do the job ?

Im looking in to injecting pre turbo and at the throttle body.
