As was said, most electric pumps you see in the catalogues are made for drag racing and simply won't move enough water to cool a 300-horse engine thats street driven. Moroso and Mezier make models that can work on long road trips- I know of one stock-horsepower Pantera that made it from LA to 'Vegas & back a few years ago for the big Fun Rally with a modified Mezier & only one or two instances of 220-and-up on the temp gauge. The useable pumps cost over $300 apiece and there are major adaptions to do correctly... There is one Mezeier model that attaches directly to a radiator tank in place of the return elbow. Front-mounting an electric pump has an advantage since the battery already is up front in a Pantera, but the ones I've seen weigh as much or more than a mechanical pump. A small Bosch electric pump in series with the stock pump (with a check valve to stop backflow) is used on a couple more cars as a supplement for around-town use.
Some time ago, I toyed with the idea of an electric water pump. I was encouraged by feedback from GT40 owners, who had fitted such items and were pleased with the result. Before moving forward, I called both Meziere's and Stewart Component's tech support people. Both companies said "don't do it"! This surprised me as both companies make such pumps. Their reasoning was that their electric water pumps don't flow enough coolant and aren't sufficiently reliable for a street application. As an alternative, both companies recommended fitting an auxilliary electric water pump as close to the outlet of the radiator as possible, and keeping the OE belt driven mechanical water pump. This would help to increase flow at idle and help reduce cavitation at higher RPM's. It can also be left running for a set period of time, after the engine's been shut off, in order to eliminate hot spots. I eventually chose the Stewart in-line electric booster pump because it offers "zero" restriction to coolant flow when it's turned off.
I recently chopped up my water pump and fitted the new Davies craig electric water pump.Ended up with a flat bulkhead cover and cooling is awesome.I did reallocated the alternater were the air con compressor used to be.The car runs very cool even in the hot australian climate.
ozzie,
Can you post some pictures? Thanks.
