Greetings,
 
I'm coming pretty close to ordering my radiator, and I think I've decided on sort of a hybrid water pump layout.  My current plan, unless someone can convince me otherwise, is to have my radiator made into two separate rads, via a divided end tank on both ends.  The mechanical water pump will feed the front of one half.  The rear of that half will go into an EWP, then output into the rear of the other half of the radiator.  The front of the second half will return to the engine. 
 
The theory is that I keep the stock pump, with an EWP as backup in case I lose the belts (which I consider the most likely failure mode).   With either the EWP, or the stock pump working alone, there will be some restriction to flow, which will be just dandy for cruise.  For climb, I'll always run both pumps, giving more than stock flow.  I can even use the stock thermostat if I want to. 
 
What do you think?  Brilliant, or stupid... don't answer that.
 
Cheers,
Rusty (great comment censored, but Paul will see it <g>)
