I am also working on the design of the end housings. The rear is
 quite simple.

 The front end housing must accommodate a water pump. Does anybody
 have any preferences for water pumps. 2nd gen or RX8? Or some else
 perhaps?

 The oil pump with be a dry sump pump with choices of several brands.

 In regard to your water pump choice question I would like to comment.
 If designing a different front cover, the water pump chosen firstly
 needs to meet the flow requirements of the engine. The pulley needs
 to match with regard to belt type and width as well as diameter.
 Then replacement cost and availability need consideration.
 Accessibility at any location in firstly N. America and potentially
 the world should be taken into consideration. Possibly the pump from
 a Cummins diesel as installed in Dodge or Ram trucks would work.

 Paul I like the 2nd generation RX8 pump. From left to right: 2nd gen
 RX8, 1st gen RX8 and Remedy RX8  (See attached).

 Maybe I'm just blowing smoke here.. Suppose turbo extracted power
 from the exhaust to drive a water pump that is redundant to a pump
 on the eccentric shaft. Plumbd together, excess power in the exhaust
 might compound to the engine through the pump?

 I'd like to see all accessories driven from the eccentric shaft or
 gear box. Built in water pump on the housing, perhaps an alternator
 in the gru. This would keep frontal area remarkably small.

Hi Paul,

Would an electric water pump be applicable in this case? You could modulate the
cooling rate from a sensor reading water temperature.

It could be mounted anywhere.

Cheers,

If some one could come up with an electric water pump capable of pumping
3 Horse Power worth of water that would be great. That's what it takes
to cool a constant 200 HP internal combustion engine.

 3 HP is 2,238 watts. 746 watts is one HP.  Add 20% for inefficiency and you have 2,865 watts.

At a battery voltage of 12 Volts  THE current out of the battery or alternator
required is 223 AMPS!!!!!

Horse Power in watts is voltage times current.
