So I'm building a 540 blower motor and have been kicking around the idea of how all of this will or won't work together.

Closed cooling system.

I also have a Superchiller how does that get plummed? From the circulation pump to the Super Chiller then to the Oil cooler, then Exhaust?

Dry sump oil system and a Engine pre-lube system. How will these two work together and how are they normaly installed (what order)?

The Blower is a Vortech unit (5 PSI), and the engine has a custom EFI system.

The chiller has to get plumbed from a separate water intake or by using a 2 stage sea pump. If you use a separate hull pick up, the pressure alone will be plenty to feed the chiller.
