radiators (on EFI engines:)

>Gentlemen, a question came up on another list about which routing 
>(paralell or series) is better for cooling an engine (fuel injected 
>ofcourse)equiped with dual radiators. 

I'd go for parallel, since the delta-T * will be greater over a larger 
surface area, giving you higher heat rejection

* delta-T meaning the difference between the coolant temp and the 
ambient air temperature
