More like a Coolant Processing Unit, but ...

I had hacked out a nice reply right after I posted this but ... the post didn post

More goodness from you cats down under at [www.daviescraig.com.au].

This system allows setting the coolant systems temp with a tap on the controller allowing you to run at 160(F) for preformance, then all the way to like 205 for fuel economy. Then it also continues to run after the key's turned off until the engine reaches the set point to prevent heat soaking the components ... too cool!

From their posted data their research points to conventional engine driven pumps actually being less efficient at high rpms due to inherent pump cavitation and excess flow not allowing the coolant optimum time in the radiator.

A good friend of mine and I conceptualized the same idea for an electric oil pump about 10yrs ago to replace the turbo timer used in turboed motors. While a turbo timer allows the engine to run on a set increment of time after the key's turned off in efforts to cool the turbo down more slowly, it does so while still adding heat to the turbo.

By using an electric oil pump in addition to the engine driven pump we devised several benefits. One was to build in a manual switch on the dash to allow you to prelube the motor before firin it up. testing I've read shows about 60-70% of engine wear comes from the dry start condition engines see every time they fire up.

We also planned to incorporate an ON light on the dash to show the system was running and utilize a Hobbs switch plumbed into the oil system to kick on the pump any time the oil pressure dropped below 20psi.

This parameter was to overcome the 12-15psi Mitsu engines get at idle and .... since it was activated by a drop in oil pressure it would also signal an oil pressure failure that might be overlooked with just an oil pressure gauge
