If your application is for a Stock or Super Stock engine, this pump is an overkill.

This Energy Recovery version of his pump is more effective when used with a Petersen external oil pressure regulator and to adjust its operation, in lieu of an oil pressure gauge, you use an inline flowmeter and adjust the oil pump for a specific oil volume flow.

I know of a racers that have been using the Energy Recovery oil pump with the external regulator successfully on high RPM engines making 1000+ HP.

If your application is a Stock Eliminator, his Pro Standard version of the pump would suffice; if a Super Stock, you can use either the Pro Standard or the Pro Maxx version of the pump.

You are absolutely correct about Vern knowing his stuff. I'm not disputing that or knocking his product. I'm just trying to get as much understanding as I can to feel confident about my customers oiling system.
This pump was special ordered and speced out for a Factory Stock application when ordered. With that said, using an external regulator is not accepted as I'm sure you know.
There are others in F/S using the energy recovery pumps that is why the owner requested to switch over.
