Hi group
Thanks to everybody I'm learning a lot here.
The idea of the electric pump sounds good to me
this is for a single rotor I have a big Rad so I think
the flow will be adequate!
It is easier to intall and it remove one belt
in my configuration.
What do you think about it?

I will take a look at the Ford Fiesta pump too
I  have to machine an adapter anyway.I'll
consider all possibility.
Thanks
Francois

Don't mess with the electric pump. Let's us assume for the moment it only takes
one HP to pump enough water for a one rotor engine. One HP is 746 watts or 
at 12 volts ...62 amps!!!!!! Right out at the total capacity of your alternator!!!!!!
The only reason those pump work in drag racing at all is the engine does
not get time to fully heat up in eight or less seconds. 

After the drag run the engine idles so the electric pump can cool them down. 
The reason they use them in drag racing in the first place is 
the fact that mechanical pumps do indeed suck HP. In some cases as much as 
three HP. So too does an electric pump pumping the same amount of water.
There is only one thing you need to remember at all times... 

There is no free lunch!!!!!!
 
Most advertising claims for these pumps are just plain false.
The US gov agency responsible for monitoring advertising claims is 
too stupid to figure it out.
