    In most cases it'll pick up around 25 hp, assuming you've got everything sealed up real good, so it can pull at least 10 inches of vacuum. 10 to 15 is where you want to be. Much more than that and you risk sucking oil away from the wrist pins. I picked up 30 hp on mine pulling 11-12. Sorry I don't have any pics of my installation. I've got the 4 vane pump and it's mounted on the drivers side of the engine, bolted to the front motor plate. Hope this helps.
