    i had over 9 psi on my riva/vortech 2 days ago (with 4" intake). but it was pretty chilly that day, normally its around 8.5.

    9.6 psi with the RR impeller on a completely stock boat. meaning stock air intake and stock intercooler. expect about 11 psi on a modified boat @8500 rpm ....thats why you need larger injectors
