Can the valley plate area be used for the relief?
IMO no reson to regulate it unless you are the paranoid type. Especially with a 3 vane pump, in that case there is ZERO reason to run a regulator
How about a 4 vane Moroso pump? My machinist told me to not even worry about regulating it with an aluminum block. Your thoughts Al?
I use a Moroso 4 vane and I am happy with it.
I do regulate it.
How much vacuum to run is a whole other discussion. I limit mine to 12".
However I know that the more vacuum I let it pull the more horsepower it makes.
I think Star is considered the top of the line.
