You said you did a lot of research but I have never heard of anyone successfully using an electric water pump on the street, just a thought, not cutting your project down I just think you may wish to look into that a bit more as I have read it just does not keep up for stop and go traffic. The TPI your using is it factory or aftermarket? Just curious cause the do make a better a better after market one.

All Jaguar waterpumps are now fully electric, as are a lot of modern landrover products. If its good enough for them, then its good enough for me :)

Right im going to continue this in the Projects section as it will turn out to be a long one

In 07 BMW started using electric water pumps, lots of models. Toyota Prius uses an electric water pump. I'm sure there are more out there as well. Being able to control the flow regardless of RPM, different mounting options, letting it run after the engine stops, I think you will see more and more as time goes on.

Will, you nailed it mate.

An electric pump is PWM controlled which basically means you can control its speed via electronics which match up your engine temp. speed and cooling requirements, keep it running when its switched off allowing it to cool properly and not allowing hot spots to occur deep in the block.
Its way more efficient and allows for less emissions as its not taking HP from the engine to drive it, and it hardly runs at full speed either.

Its win win all round, yep, i agree the early ones were a bit pants, but the new generation of pumps are bloody amazing, also EPAS systems are way better than standard PAS as they are PWM speed controlled too.

Its the 21st century guys :)
