I will be very interested to see how the performance of the electric cooling devices improve the fuel economy. I have never been able to get my mind around it though. I remember from my high school physics class that every conversion between energy types is less than 100%....many are well under 50% the best seem to be more like 90%. Changing from the mechanical water pump to one that is electric changes from one with no conversions (mechanical to mechanical) to one with a conversion from mechanical to electrical and then from electrical back to mechanical (right?). Its hard for me to see how you can come out ahead.

Now you mention better control of cooling and the ability to cool after shut down and I can understand that but cannot see how that will convert to increased fuel economy.

I wish you the best though and am waiting to hear your reports of how it all pans out when you get it all working.

I always wanted to try some aero mods to increase fuel economy further on that car.....a deep front spoiler, smooth wheel covers on front, skirts on the back, an extension of the roof line perhaps and a small relatively flat spoiler on the deck.

I am planning to build up Pancakes the 82 240 I got from TheDon with a fresh engine and at minimum a taller rear end. I might even try putting in a five speed if I decide not to use the wagon I bought from RLeo as is.

Sorry for the thread jack.
