The hv pump we have only put's out a maxium of 55 psi cold and 25-30 psi hot . That's the most it's ever put out no matter what oil weight we try. So I guess it's either change relief valve or spring and get the correct pressure or get a standard oil pump and opening it up like some people do. The oil pan we have is really not worth the effort and time to fix so I am either going to get a 8qt moroso or the milodon 9qt ss pan. So what ever oil pump would be better to use in either application is what I need to use. Anyone reccomend getting a stock oil volume oil pump and open it up and get the right spring for oil pressure? Any power to be had or just a waste of time?



With the pump you have now it looks like the by pass
spring is a bit on the weak side... most open at about
65-70 psi.... I always blend in the bores in the pump
just to help with the flow(make sure you clean it out
real good and that means taking the by pass out to
make sure its all clean)... a standard pump will take
a LITTLE less power to spin... would you see a difference..
nope
